When many people across the country, not to mention in public office, believe that the world is run by a group of Satanic pedophiles that includes top Democrats and Hollywood elites, and that former President Trump is leading a secret mission to bring these evildoers to justice, one can’t help but ask if they’re at least to some degree mentally impaired.

Conspiracy theories are often received with psychiatric connotations; associated with paranoid plan-hatchers, and nonbelieving outsiders. But whereas theories such as QAnon strain credibility for many people, we would argue that they are likely not the product of psychosis or mental illness; nor do conspiracy theories in general represent delusions.
For one thing, surveys have consistently revealed that about 50% of the population believes in at least one conspiracy theory. Furthermore, there are several substantive differences between conspiracy theory beliefs and delusions.
Some researchers consider conspiracy theories to be “a subset of false beliefs,” but most scholars, ourselves included, do not prejudge their validity or veracity. Real-life conspiracies, such as the CIA’s MK-Ultra program, have clearly occurred throughout history.
Our central contention is that belief in conspiracy theories is distinct from psychosis, and more closely resembles extreme but subculturally sanctioned religious or political beliefs. However, the line between believing in conspiracies and being delusional becomes blurred when the believer becomes part of the conspiracy theory and feels compelled to act on the belief as part of a personal mission.
Take Edgar Maddison Welch, a 28-year-old man who firmly believed the so-called “Pizzagate” conspiracy theory – the baseless claim that Hillary Clinton and Democratic elites were running a child sex-trafficking ring out of a Washington, DC, pizzeria. Seeing himself a potential savior of children, Mr. Welch drove 350 miles to the pizza shop from his home in North Carolina in December 2016 and fired three shots from an AR-15 style rifle into a locked closet door, ultimately surrendering to police. However, on questioning he quickly conceded, “The intel on this wasn’t 100%.”
Who believes in conspiracy theories?
Given that half the population believes in at least one conspiracy theory, it should come as little surprise that there is no reliable “profile” for believers. Although some studies have suggested associations with low education, right-wing political orientation, and certain personality traits like subclinical paranoia and schizotypy, such findings have been inconsistent and may vary across specific conspiracy theory. Associations between conspiracy belief and paranoia suggest overlap within a “conspiratorial mindset,” with recent evidence that “distrust of officialdom” is a key mediator between believing in conspiracies and political ideology.
Dr. Joseph M. Pierre
Other quantitative “cognitive quirks” reported in those who believe in conspiracies are a need for certainty and control, a need for uniqueness, illusory pattern perception, and lack of analytical thinking. It’s unclear which of these factors may represent universal cognitive explanations for conspiratorial beliefs, vs. those that might be related to specific beliefs, such as the need for certainty during times of crisis and societal upheaval, when conspiracy theories tend to flourish.
Much of the research on conspiracy theory belief is based on the questionable premise that it’s best understood at the level of the individual’s psychopathology, or the “deficit model,” as it’s called. One of us (JMP) has instead proposed a two-component model that includes social and informational contexts. The first component – epistemic mistrust – involves mistrusting conventional, “authoritative” knowledge. The second involves biased information processing and exposure to misinformation, often transmitted by word of mouth, or through social networks. With this model, believing in conspiracy theories could be conceived as involving “delusion-like beliefs,” but not frank psychosis or full-blown delusions, as one might see, for example, in schizophrenia.
Indeed, many of the cognitive characteristics associated with conspiracy theory belief are universal, continuously distributed traits, varying in quantity, rather than all-or-none variables or distinct symptoms of mental illness.
Essentially, delusions are fixed, false, usually unshared beliefs, often based on subjective “inner” experience. (One rare exception is the so-called folie à deux, in which two people appear to “share” the same delusion; however, psychiatrists have long debated whether both individuals should be considered truly delusional). The delusion’s content is often “self-referential”; i.e., focused primarily on the believer.
In contrast, conspiracy theories are usually, but not necessarily, false. They are typically shared beliefs that don’t explicitly or directly involve the believer, and are based on evidence that one finds “out there,” such as on the Internet. This speaks to the highly communal nature of so many conspiracy theories – networks of like-minded individuals reinforcing one another’s beliefs in a particular socio-cultural context.
Conspiracy theory belief, COVID-19, and medical intervention
As for medical conspiracy theories, none have flourished recently more so than those involving the COVID-19 pandemic. As a recent editorial by Stein and colleagues noted, “Some conspiratorial claims include assertions that COVID‐19 is a hoax; arguments that the virus was created artificially and spread on purpose as a bioweapon; or allegations that governments are using the emergency situation to pursue their antidemocratic goals. … Other conspiracies argued that people in power are taking advantage of the pandemic as a plan to inject microchip quantum-dot spy software and monitor people.”
Stein and colleagues make the important point that a “key difference between COVID‐19 and the 1918 flu pandemic ... is that [now] a highly interconnected world, to a great extent on social media, is setting the stage for distributing information and misinformation about COVID‐19.”
Consider the following composite vignette: Mr. A is a 70-year-old retiree with a history of COPD who has been advised by his PCP to get vaccinated against COVID-19. He is extremely reluctant to do so, fearing that “the vaccine is going to change my DNA” and “might even give me COVID.” He has heard from friends on social media that vaccine developers “faked the results” and are “in cahoots with the federal government.” Mr. A has heard “experts” declare the vaccines safe, but does not trust them. Mr. A has no psychiatric or substance abuse history, and there are no cognitive, perceptual, or other abnormalities in Mr. A’s mental status exam.
Mr. A’s beliefs qualify as a “conspiracy theory,” but probably represent widely held misconceptions about COVID-19 vaccines, as well as widespread mistrust of pharmaceutical companies and the federal government. Based on the information provided, there is no basis for concluding that Mr. A is psychotic or delusional. His beliefs appear to be the result of “epistemic mistrust” of authoritative informational accounts, biased information processing, and exposure to misinformation.
How should the physician manage and care for patients like Mr. A? Absent frank delusions, there is no role for antipsychotic medication, though for extremely anxious patients, a time-limited course of an antianxiety agent may sometimes be warranted. In addition to providing accurate medical information to the patient, the physician should avoid arguing, or trying to “talk the patient out of” his or her belief. Instead, the focus should be on sustaining and strengthening the physician-patient alliance, establishing an atmosphere of respect and safety, clarifying differences in trusted sources of medical information, and allowing the patient time to process the physician’s recommendations.
One-to-one engagement with health care providers has proved effective in reducing vaccine hesitancy and correcting misinformation. For patients with less fixed conspiracy theory beliefs, it may sometimes be helpful to gently offer alternative hypotheses to the patient’s conspiracy theory, using elements of cognitive-behavioral therapy (CBT). For example, a physician might ask, “Is it possible that the online source you read was mistaken about the vaccine changing your DNA?” while reminding patients that – contrary to popular belief – mRNA vaccines have been in development against cancer for several decades.
Challenging beliefs collaboratively and acknowledging areas of uncertainty, rather than confronting or arguing about false beliefs, can foster trust between physician and patient and, at the very least, open a dialogue regarding potential exposure to medical misinformation. “Inoculation” strategies that present and then dispel misinformation before patients become aware of it are among the best supported strategies for mitigating conspiracy theory belief. Ideally, physicians and health care systems should maintain an ongoing “inventory” of medical misinformation circulating online and “beat it to the punch” with reliable information.
Finally, because believing in conspiracy theories is often associated with a sense of uncertainty, and feeling that one’s life is “out of control,” medical interventions can be framed as ways of regaining control and appealing to patients’ values; for example, saying, “By getting the vaccine, you’ll be more likely to stay in good health, protect your family, and do all the things you want to do.”

The antidepressant fluvoxamine shows promise in preventing people infected with coronavirus from developing serious symptoms and having to be hospitalized, according to a nonrandomized study of California racetrack workers.
Dr. Caline Mattar
“What we observed was that of all the patients who received fluvoxamine, none of them had a severe COVID infection that affected their lungs or their respiratory status,” Caline Mattar, MD, told KNBC in Los Angeles. Dr. Mattar is an infectious disease researcher at Washington University in St. Louis who helped conduct the study that was published in Open Forum Infectious Diseases.
Fluvoxamine, which is sold under the brand name Luvox, is a selective serotonin reuptake inhibitor (SSRI) often prescribed for people diagnosed with obsessive-compulsive disorder. It’s been on the market for over a decade.
Two-hundred employees at Golden Gate Fields Racetrack in Berkeley, Calif., tested positive for COVID-19 last November. Track physician David Seftel, MD, offered fluvoxamine to 113 of them, having learned of a previous randomized study of COVID-19 patients that indicated fluvoxamine helped ward off serious illness, Science News said.
The 65 workers who took a 2-week course of the drug didn’t have to be hospitalized, didn’t have serious symptoms, and felt better after 2 weeks, the study said. Six of the 48 workers who turned down fluvoxamine had to be hospitalized, two required intensive care, and one died, the study said.
“Overall, fluvoxamine appears promising as early treatment for COVID-19 to prevent clinical deterioration requiring hospitalization and to prevent possible long haul symptoms persisting beyond 2 weeks,” the study said.
The authors stressed that their findings were “a real world evidence study” necessitated by the urgency of the coronavirus pandemic.
They said their research needed verification from a randomized, controlled trial. Such a study is now being conducted by Washington University and other schools, KNBC said.
The track workers who were infected were predominantly male and Latino, and 30% had chronic medical problems such as diabetes or high blood pressure, Science News said.

The United States has now reported more than 450,000 COVID-19 deaths during the pandemic, adding 3,912 more on Wednesday, according to data from Johns Hopkins University.
Daily COVID-19 deaths still remain high in the United States, though they’ve decreased slightly from the peak of 4,466 deaths on Jan. 12.
The United States also reported more than 121,000 new COVID-19 cases on Wednesday, which is down from a peak of more than 300,000 new cases on Tuesday. In total, more than 26.5 million people in the United States have been diagnosed with COVID-19, making up a quarter of the 104.5 million cases reported worldwide.
The 7-day average for COVID-19 hospitalizations and deaths continues to decline, according to the COVID Tracking Project. The 7-day average for hospitalizations is around 96,500, and the 7-day average for deaths is about 3,000. With the exception of Vermont, all states and territories have reported declines or no changes in their hospitalizations and deaths.
“We have seen the 7-day average for new deaths decrease for over a week. At the same time, states are reporting an average of 3,000 people dying per day,” the COVID Tracking Project wrote in a post on Twitter. “The data is hopeful and devastating.”
More than 2.2 million COVID-19 deaths have been reported worldwide. The United States continues to report the most deaths, followed by Brazil with 227,500, Mexico with 161,200, and India with 154,700 deaths.
The U.S. COVID-19 death toll could reach 496,000-534,000 by the end of February, according to a new forecast by the CDC, which includes models from 36 national groups. Deaths will likely decrease during the next 4 weeks, with about 11,300-22,600 deaths possibly reported during the last week of February.
The 534,000 total would equal about 1 death for every minute of the pandemic, according to CNN, given that the first U.S. death was reported on Feb. 29 last year.

In total, more than 26.5 million people in the United States have been diagnosed with COVID-19, making up a quarter of the 104.5 million cases reported worldwide.
The 7-day average for COVID-19 hospitalizations and deaths continues to decline, according to the COVID Tracking Project. The 7-day average for hospitalizations is around 96,500, and the 7-day average for deaths is about 3,000. With the exception of Vermont, all states and territories have reported declines or no changes in their hospitalizations and deaths.
“We have seen the 7-day average for new deaths decrease for over a week. At the same time, states are reporting an average of 3,000 people dying per day,” the COVID Tracking Project wrote in a post on Twitter. “The data is hopeful and devastating.”
More than 2.2 million COVID-19 deaths have been reported worldwide. The United States continues to report the most deaths, followed by Brazil with 227,500, Mexico with 161,200, and India with 154,700 deaths.
The U.S. COVID-19 death toll could reach 496,000-534,000 by the end of February, according to a new forecast by the CDC, which includes models from 36 national groups. Deaths will likely decrease during the next 4 weeks, with about 11,300-22,600 deaths possibly reported during the last week of February.
The 534,000 total would equal about 1 death for every minute of the pandemic, according to CNN, given that the first U.S. death was reported on Feb. 29 last year.

Higher fiber intake may be associated with decreased risk of depression in premenopausal women, new research suggests.
Nic_Ol/Thinkstock
Investigators analyzed data from close to 6,000 pre- and postmenopausal women. They found that, in premenopausal women, dietary fiber intake was higher among those without depression versus their counterparts with the disorder in a dose-dependent manner. However, there appeared to be no relationship between higher fiber intake and depression risk in postmenopausal women.
“We think the most important finding of our study is that dietary fiber intake was inversely associated with depression in premenopausal but not postmenopausal women,” lead author Yunsun Kim, MD, resident, department of family medicine, Chung-Ang University Hospital, Seoul, South Korea, said in an interview.
“We hope that the findings of this study could form the basis of future investigations to determine the causal relationship between dietary fiber intake and depression,” she added.
The prevalence of depression is twice as high in women, compared with men, which may be attributable to a number of factors, including hormonal status – especially during menstruation and menopause, the authors wrote.
Previous research suggests a potential association between dietary fiber and depression in premenopausal women and between estrogen and gut microbiota. Fiber intake has an impact on gut microbiota, Dr. Kim said.
“We are motivated by the fact that depression provokes disease burden internationally and we would like to find modifiable factors that could prevent depression, especially in women, who are more vulnerable to depression,” she noted.
To investigate, the researchers drew on data from the Korea National Health and Nutrition Examination Survey for 2014, 2016, and 2018. Of the total number of women who met inclusion criteria (n = 5807; mean age, 47.11), roughly half were premenopausal and half were postmenopausal (n = 2,949 [mean age, 36.23 years] and n = 2,868 [mean age, 62.73], respectively).
Dietary fiber intake was assessed using the 24-hour dietary recall method, while depression was assessed using the Patient Health Questionnaire-9. The researchers used the Dietary Reference Intakes for Koreans to define a sufficient intake of dietary fiber (i.e., 12 g/1,000 kcal).
Covariates included chronic diseases, body mass index, medications, smoking status, alcohol use, physical activity, and sociodemographic factors.
When the researchers looked at all participants, they found that the estimated mean dietary fiber intake was significantly higher in women without depression, compared with those with depression (14.07 g/1,000 kcal/d; 95% confidence interval, 13.85-14.29 vs. 12.67 g/1,000 kcal/d; 95% CI, 11.79-13.55; P = .003).
Although the relationship remained significant in premenopausal women, it lost significance in postmenopausal women.
A 5% decrease in the prevalence of depression in premenopausal (but not postmenopausal) women was found in those with an increased intake of dietary fiber – i..e, there was a 1-g increase for every 1,000 kcal of daily energy intake, after adjusting for potential confounders in premenopausal women (OR, 0.949; 95% CI, 0.906-0.993]).
“The inverse relationship between dietary fiber intake and depression could be explained by the gut-brain interactions,” said Dr. Kim.
“Changes in the gut microbiota composition may affect neurotransmission and various neuropsychiatric phenomena in the brain,” she said, noting that previous studies have suggested that dietary fiber intake “may modulate the richness and diversity of the gut microbiota, and this change may promote brain health by affecting neurotransmission.”
Because postmenopausal women experience estrogen depletion, “the decreased interaction between estrogen and the gut microbiota may be related to the insignificant association between dietary fiber intake and depression in postmenopausal women,” she said.
Despite the lack of a significant association between postmenopausal depression and fiber intake, Dr. Kim said she “advises middle-aged women to have dietary fiber–rich diets, regardless of their menopausal status.”
Link between food and mood
In a comment, Stephanie S. Faubion, MD, MBA, a professor and chair of the department of medicine and the Penny and Bill George director of the Mayo Clinic’s Center for Women’s Health in Rochester, Minn., noted the study was cross-sectional and therefore the direction of the association could not be determined and “causality cannot be assumed.”
It is possible that “depressed women are less likely to eat fiber than women without depression. For example, a depressed woman may be more likely to sit on the couch eating Cheetos than shopping for and preparing a healthy meal,” said Dr. Faubion, who is also the medical director of the North American Menopause Society and was not involved with the study.
She noted that other potential confounders, including access to fresh fruits and vegetables or geographic locations could also “impact the findings and it is important that we do not somehow imply that eating a high-fiber diet can in any way treat a major depression.”
Nevertheless, the study does “add to the body of evidence suggesting a link between diet and overall health, including brain health,” Dr. Faubion said.
One take-home message for practicing clinicians is that a healthy diet that includes fiber may benefit women (and men) for a number of reasons and “appears to be linked to mood.”
More research is needed “to determine the pathophysiologic mechanisms (such as potential brain-gut connection that involves the microbiome) that may explain this association,” Dr. Faubion added.
No source of funding listed. Dr. Kim and coauthors, as well as Dr. Faubion, disclosed no relevant financial relationships.

Psychiatrists with expertise in delusional infestation have some advice for dermatologists, infectious disease specialists, and primary care physicians who encounter affected patients: If you want to try to help them, initiate treatment yourself.
Dr. Peter Lepping
“If you see it, try and treat it. These patients are unlikely to agree to see a psychiatrist,” Peter Lepping, MD, said at the Entomology 2020 annual meeting.
Indeed, one of the hallmarks of delusional infestation (DI) is a refusal to even consider referral to a mental health professional, noted Dr. Lepping, a consultation-liaison psychiatrist at Bangor (Wales) University who, together with an infectious disease specialist, codirects one of the world’s few DI multispecialty referral clinics, located at the University of Liverpool School of Tropical Medicine.
That being said, he offered another piece of advice: “Accept that it is not easy to help these patients.”
Dr. Lepping was among a group of distinguished psychiatrists, dermatologists, entomologists, and a neurologist at the annual meeting who participated in a comprehensive session devoted to DI. The experts shared tips on making the diagnosis, establishing the rapport necessary to persuade affected patients to try taking a very-low-dose antipsychotic agent for their delusion, and how to achieve a high rate of therapeutic success. They also highlighted recent research advances in the field, including brain MRI evidence suggesting that impaired somatosensory neural networks mediate symptoms in DI, but not in nonsomatic delusional disorders.
COVID-19 pandemic triggers surge in DI
Entomologist Gail E. Ridge, PhD, has taken notes on all of her thousands of consultations with individuals with suspected DI since the late 1990s. A sharp jump in such contacts occurred during the Great Recession of 2008 in conjunction with the widespread social distress of job loss and threatened economic ruin. Now the same thing is happening as the catastrophic COVID-19 pandemic stretches on. Indeed, during the first 8 months of the pandemic she documented 500 interactions involving people with suspected DI. She’s learned to identify the clues, including a chattering mind, defensiveness, physician avoidance, and rigid body tension.

“They’re fearful of judgment and suggestions of madness. And they’ll pounce on any perceived negativity. I never debunk beliefs; that can immediately backfire. If the medical profession was educated about DI, then many cases could be caught early. I, as the entomologist, and the mental health professionals are often last in line to be seen,” said Dr. Ridge, director of the Insect Information Office at the Connecticut Agricultural Experiment Station in New Haven.
She has noticed a recurring theme in her interactions with these patients: DI often starts with a real underlying medical condition, such as, for example, a cutaneous drug reaction, which over time, progresses to gain a psychiatric component. And she has found that a tipping point often occurs after roughly 6 months of unrelieved symptoms and sensations. Prior to that, affected individuals are concerned about their condition and will seek medical help in a genuine effort to understand what’s going on. They can be redirected. After about 6 months, however, Dr. Ridge has observed “they slide into the rabbit hole of fanaticism and despair.”
Arriving at the diagnosis
In the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), DI is classified as a “delusional disorder, somatic type 297.1 F22.” The diagnosis requires that the delusion be present for at least 1 month, criteria for schizophrenia are not met, and the condition cannot be attributed to other medical or neuropsychiatric conditions.
“Many of these people are very high-functioning. I have corporate CEOs who fly in to see me in their private jets. At work, they’re king of their domain. At home, their family is falling apart because of their delusion,” said Dirk M. Elston, MD, professor and chair of the department of dermatology and dermatologic surgery at the Medical University of South Carolina, Charleston.
Dr. Dirk M. Elston
“These people suffer, and the people around them suffer,” he emphasized.
Dozens of medical conditions can cause intractable itching or biting sensations. Far and away at the top of the medical differential diagnosis is thyroid disease, given its high incidence and frequent presentation with anxiety and itch. Other possibilities that can readily be ruled out via lab tests include substance use – especially involving amphetamine/methamphetamine, cocaine, or opioids – liver or kidney disease, diabetes and other sources of peripheral neuropathy, polycythemia, dermatitis herpetiformis, and pemphigus, Dr. Elston said.
Scott A. Norton, MD, MPH, MSc, a dermatologist and preventive medicine specialist at the Uniformed Services University of the Health Sciences in Bethesda, Md., noted that a diagnosis of DI requires three elements: The presence of abnormal sensations in the skin, a patient’s tenacious conviction that the sensations are caused by an infestation, and a lack of supporting evidence for that conviction.
Dr. Scott A. Norton
Taking an accurate medical history can be a challenge in these patients because they are often so guarded. They won’t disclose that they’ve already seen other health care providers, or that they’ve been self-treating with OTC veterinary medicine products, such as high-dose topical or oral ivermectin. They’ll often even deny repeated scratching despite clear evidence to the contrary from the skin exam.
As a dermatologist, Dr. Norton considers his first task to be a search for evidence of an infestation. Scabies is usually the first diagnosis proposed to account for the uncomfortable skin sensations. The presentation can be subtle. While the classic teaching is that the telltale signs of infestation by Sarcoptes scabiei are burrows in the skin and a rash in the web spaces between the fingers, he finds these features are often absent or equivocal.
“I think there are two more reliable presentations of scabies: Check to see if there’s symmetric involvement of the volar or palm side of the wrists; if there isn’t, I’m skeptical of the diagnosis. And every male older than 1 year of age with scabies will have scabies nodules on their genitalia. If the penis, the glans, or the scrotum aren’t involved with the nodules, I discard scabies as a possible diagnosis and look for evidence of other skin conditions that can plausibly explain the sensations and skin lesions, like eczema, contact dermatitis, scalp folliculitis, or dry skin,” he said.
If he can’t find evidence of infestation, he next systematically looks for another dermatologic cause of the patient’s sensations. When that proves fruitless, he tries to determine if there might be a biomedical or neuropsychiatric cause, such as depression, anxiety, schizophrenia, or dementia.
Taking a personal hygiene history is helpful. Patients who believe they have an infestation may bathe or shower three to five times daily with harsh soaps, causing dry, inflamed, itchy and uncomfortable skin.
“Many patients are thrilled to hear the good news that the history, physical examination, and lab tests do not show an infestation and that we have another explanation to account for their unwanted sensations. However, there are some patients who vehemently reject that idea and immediately return to their unwavering, unalterable belief that they are in fact infested. At this point, the possible diagnosis of DI looms large,” the dermatologist said.
Clues suggestive of DI include a patient’s obsessive focus on collecting “specimens” of the offending pathogen in Ziplock bags for assessment during the office visit – “usually a mix of unhelpful household debris and environmental detritus” – and eager presentation of a lengthy and detailed infestation diary, Dr. Norton said.
“Among the most distinctive signs that the patient is detached from reality are the biologically implausible descriptions and explanations of the supposed attacking organism. It’s a fanciful amalgamation of mutable features, behaviors, and life cycles composed of a composite of taxonomically unrelated organisms – for example, fungal hyphae with wings – that shapeshift at will to evade detection,” he said.
Dr. Elston observed that DI skin lesions are typically excoriated, sometimes because of a patient’s systematic use of a sharp object in an effort to dig out the infestation.
“One of the clues is the angularity of the lesion,” the dermatologist noted. “We always say round-to-oval lesions suggest an inside job; angulated lesions suggest an outside job, like fingernail work. There’s often a row of good healing border showing there’s really nothing wrong with wound healing, but a fibrinoid base where the excoriations have occurred. And the lesions are often in various stages of healing.”
Don’t forget neuropathic itch in nondelusional individuals as a potential cause of sensations of infestation and self-injury due to relentless scratching, urged Anne Louise Oaklander, MD, PhD, associate professor of neurology, Harvard Medical School, Boston, who is director of the nerve unit and the neurodiagnostic skin biopsy lab at Massachusetts General Hospital, Boston.
Dr. Anne Louise Oaklander
“There’s no one cause of patients’ impressions that they may have insects. Let’s be sympathetic: It is a normal assumption that insects may be present if the skin itches. One problem is that when patients don’t get good medical diagnoses they make up their own explanations, and sometimes these include persistent ideas of infestation. Many of them don’t realize that their scratching is a cause, not a result, of their skin lesions,” said Dr. Oaklander, who has conducted pioneering research on unintentional self-injury due to neuropathic itch accompanied by loss of pain signaling.
“Rapport first, medication later”
“The office visits are typically difficult to conclude, but skills can be learned and make it much easier to help these people,” Dr. Elston said.
John Koo, MD, emphasized that establishing rapport is “by far” the most important part of managing patients with DI.
Dr. John Koo
“Rapport first, medication later. This may require multiple visits,” said Dr. Koo, professor of dermatology at the University of California, San Francisco, who is a board-certified psychiatrist.
He makes sure he walks into the examination room all smiles and positivity. Patients with DI are eager to expound on their ailment; he lets them talk for a while, then when the timing is right, he actively encourages them to shift their focus away from etiology to treatment.
Dr. Koo and coworkers have described a spectrum of mental fixation in DI ranging from having only crawling and biting sensations, progressing to holding an overvalued idea as to their cause, then on to DSM-5 somatic preoccupation, followed by becoming truly delusional, and finally terminal delusion, where the patient doesn’t care about getting better, but only wants the physician to agree there is an infestation (J Clin Exp Dermatol Res. 2014 Oct. 3. doi: 10.4172/2155-9554.1000241).
“You cannot argue with people with delusions. How you talk to them as a clinician depends on whether they are entirely delusional or not,” he advised. “I cannot agree with their ideation, but I can agree with their misery – and that’s how I make a connection.”
Declining a DI patient’s request for a skin biopsy when it’s obvious there is no infestation can lead to a counterproductive power struggle. Instead, Dr. Koo turns the patient request into an opportunity to form a verbal contract: “I ask, ‘If the result comes back negative, can you be open-minded about the possibility of other etiologies besides parasites?’ ”
As for Dr. Norton, when his schedule shows a patient is coming in for a first visit for a supposed skin infestation, he tells his staff to expect a lengthy session as he works at establishing a good relationship.
“When my patients arrive with bags of specimens, I ask them to select two or three that they’re most confident will have a creature in them. Then I bring a two-headed microscope into the exam room and ask the patient to join me in examining the material. It helps with rapport by showing that I genuinely want to determine if there’s an infestation,” he explained.
He then sends the specimens to a laboratory, which provides a full report of the findings.
In performing a skin biopsy in a patient with suspected DI, Dr. Norton routinely biopsies two sites so the patient can’t claim sampling error when the pathology report comes back with no pathogens or parasites found. Also, he asks the patient to choose biopsy sites with intact skin where he or she believes the infestation exists. There is no point in biopsying excoriated lesions because they often contain snagged textile fibers.
Another rapport-building strategy: “I try to design a treatment regimen that will palliate the uncomfortable sensations and help relieve the patient’s misery while we continue working towards treating those delusions,” Dr. Norton said.
This might entail cutting back to one lukewarm shower per day with gentle or no soap, coupled with moisturizing, oral antihistamines or doxepin for itch, topical corticosteroids for the associated inflammation, and oral or topical antibiotics for any secondary bacterial skin infection.
What he doesn’t recommend as a rapport-building strategy or simply in order to get the patient out of the office is offering a therapeutic trial of an antiparasitic agent. That’s counterproductive. It may reinforce the false belief of infestation, and when the medication doesn’t bring lasting belief, the patient may conclude the infestation is resistant to conventional treatment.
Dr. Koo tells affected patients that he suspects they have Morgellons syndrome. He doesn’t call it DI in their presence.
“These people would not like their condition to be called delusional,” he explained. “Morgellons is a more neutral term. I tell them it’s a mysterious condition, and that what I’m really interested in is in trying to get them out of their misery.”
Treatment tips
Dr. Koo’s first-line medication for DI is pimozide (Orap), which in the United States has the advantage of being approved only for Tourette syndrome; it’s an antipsychotic without the perceived stigma of a psychiatric indication.
“Many of these patients will not consider taking any medication that has any psychiatric indication,” he noted.
Low-dose pimozide is highly effective, according to Dr. Koo, who recommends starting at 0.5 mg to 1 mg/day, increasing by 0.5 mg/day every 2-4 weeks. The drug is usually effective at a dose of 3 mg/day or less. Once a patient’s symptoms become clear or almost clear, the patient is maintained on that dose for another 3-4 months, then tapered by 0.5 mg/day every 2-4 weeks.
“In 35 years of seeing a new patient on average every week or two, I’ve had only five patients with one recurrence and one patient with two recurrences. All six responded to repeat therapy,” Dr. Koo said.
Side effects at these low doses are “very rare,” he added. Diphenhydramine (Benadryl) at 25 mg up to four times daily is effective for complaints of stiffness or restlessness. Prolongation of the QT interval is a potential concern, but Dr. Koo has never encountered it despite routinely ordering ECGs for patients on pimozide with known heart disease or who are over age 50.
When a patient can’t tolerate pimozide, Dr. Koo’s second-line antipsychotic for DI is low-dose risperidone (Risperdal), which is also highly effective.
Dr. Lepping noted that the European situation is different. There, unlike in the United States, pimozide has regulatory approval as an antipsychotic, so it loses the advantage of being an under-the-radar neuroleptic. His go-to medication is the first-generation antipsychotic sulpiride (Dogmatil), which he finds has a more favorable side effect profile than pimozide, particularly in the elderly. (Sulpiride is not approved in the United States.)
In treating DI, he prefers more dopaminergic-focused antipsychotics over those covering a broader spectrum of receptors. His alternatives to sulpiride include risperidone and olanzapine, atypical antipsychotics. He explains to patients that just as aspirin is used in low doses for its antiplatelet effect and in higher doses for pain relief, these medications can help them feel better at much lower doses than for schizophrenia.
“Once we get some rapport and a trusting relationship going, we normally try to persuade people to basically try something against their better judgment. We know that they don’t believe in it, but you try to get them to at least try something because everything else has failed,” Dr. Lepping explained. “We tell them it’s a condition we have seen before, and we have seen these medications to be useful because they are good for their distress, they help with making them calmer, and they might help with their symptoms. We say, ‘What do you have to lose if you trust us?’
“About 60% of our patients take the medication and almost invariably they all get better,” the psychiatrist said. “The others we either lose to follow-up or they just refuse to take the medication.”
A patient’s first visit to the Liverpool multispecialty DI referral clinic is 1 hour long. “They know that in advance, and we very much stick to that hour. We say to people up front, ‘We have an hour – that’s a lot, but we don’t have more,’ ” he said.
The initial visit is typically followed by two to four 30-minute follow-up visits. Dr. Lepping recommends that when possible, patients with DI should be seen jointly by a psychiatrist and a nonpsychiatrist physician. He finds this approach leads to substantially better clinical outcomes than with a single health care provider.
“If you have two people in the clinic with the patient, when you get really annoyed and your amygdala really starts going, that’s the time when you can then turn to your colleague and say, ‘Oh yes, and Professor Squire, what do you have to say to that?’ So as you see the red mist rising in yourself because you’re getting so exasperated, you have the other person there to take over so you can calm down. And then the other person does the same. That can be really important to deescalate a heated situation,” Dr. Lepping explained.
Roughly 10% of patients with DI have what is termed folie à deux, where the delusion of infestation is shared by another person.
“Anecdotally, I would say those are much more difficult to treat,” said Jason S. Reichenberg, MD, MBA, professor of medicine (dermatology) at the University of Texas at Austin and president of the Ascension Medical Group Texas.

“It’s like getting somebody to quit smoking when everybody else in the house is still smoking. It’s very hard to convince a single family member that they’re wrong when everybody else in their family keeps telling them they’re right,” he said.
Recent advances in DI research
Dr. Lepping and coinvestigators at multispecialist DI clinics in London, Italy, and Moscow reported in an unusually large observational study of 236 affected patients that longer duration of untreated psychosis was associated with significantly worse clinical outcome. It’s a finding consistent with Dr. Koo’s construct of progressive stages of delusionality, and it underscores the need for early treatment.
“Having said that, improvement is still possible, even if people have had quite a long time of untreated psychosis,” Dr. Lepping said. The same study also showed that older age at illness onset was inversely associated with good outcome.
In another study, Dr. Lepping and colleagues reported that substance use involving amphetamines, cocaine, opioids, and other drugs that can cause itch was roughly twice as common in a group of patients with DI compared to the general population. “I highly recommend, if at all possible, a drug screen in suspected DI,” he said.
In a large survey of U.S. and Canadian veterinarians, Dr. Lepping and coinvestigators found that these practitioners not infrequently encountered delusional infestation among pet owners who claimed their dog or cat is infested when it’s not. This is called “delusion by proxy,” and it often leads to unwarranted animal euthanasia. Some of these pet owners claim they, too, are infested, which the investigators termed “double delusional infestation.”
MRI studies
Recent structural brain MRI studies support the concept that impaired somatosensory neural networks mediate the delusional symptoms of DI, but not in delusional disorders without somatic content. This was demonstrated in an MRI study by Dr. Lepping and others conducted in 18 patients with DI, 19 others with nonsomatic delusional disorders centered on themes of persecution or jealousy, and 20 healthy volunteers. The DI group had lower gray matter volume in prefrontal, thalamic, striatal, and insular regions of the brain compared to the other two groups.
Of note, mapping of the insula and dorsal striatum indicates they are part of the peripersonal space network, which integrates tactile and visual perceptions involving the area near the body surface. The insula also mediates feelings of pain and disgust.
Some of the same investigators have also recently reported brain MRI evidence specifically of cerebellar dysfunction in patients with DI, who displayed decreased gray matter volume in left lobule VIIa of the cerebellum and increased gray matter volume in bilateral lobule VIIa/crus II compared to patients with non-somatic delusions. This points to a role for impaired cerebellar neural networks related to somatosensory perception in patients with DI but not in those with non-somatic delusions.
Delusional infestation: What’s in a name?
Ekbom syndrome. Delusional parasitosis. Morgellons syndrome. These and other terms are increasingly giving way to ‘delusional infestation’ as the preferred moniker for the disorder. That’s in part because the delusional focus in patients with this condition has shifted over time. In the 19th century, for example, affected patients often attributed their infestation to typhus.
In contemporary practice, roughly one-quarter of affected patients think they are infested by small inanimate objects, most commonly fibers or threads emerging from the skin, rather than by parasites, insects, or worms. In a study of 148 consecutive European patients with suspected DI, Dr. Lepping and coinvestigators reported only 35% believed they were infested by parasites.
“The name ‘delusional infestation’ emphasizes the constantly changing pathogens and covers all present and future variations of the theme that are bound to occur,” Dr. Lepping observed.
All speakers reported having no conflicts of interest.
Psychiatrists with expertise in delusional infestation have some advice for dermatologists, infectious disease specialists, and primary care physicians who encounter affected patients: If you want to try to help them, initiate treatment yourself.
Dr. Peter Lepping
“If you see it, try and treat it. These patients are unlikely to agree to see a psychiatrist,” Peter Lepping, MD, said at the Entomology 2020 annual meeting.
Indeed, one of the hallmarks of delusional infestation (DI) is a refusal to even consider referral to a mental health professional, noted Dr. Lepping, a consultation-liaison psychiatrist at Bangor (Wales) University who, together with an infectious disease specialist, codirects one of the world’s few DI multispecialty referral clinics, located at the University of Liverpool School of Tropical Medicine.
That being said, he offered another piece of advice: “Accept that it is not easy to help these patients.”
Dr. Lepping was among a group of distinguished psychiatrists, dermatologists, entomologists, and a neurologist at the annual meeting who participated in a comprehensive session devoted to DI. The experts shared tips on making the diagnosis, establishing the rapport necessary to persuade affected patients to try taking a very-low-dose antipsychotic agent for their delusion, and how to achieve a high rate of therapeutic success. They also highlighted recent research advances in the field, including brain MRI evidence suggesting that impaired somatosensory neural networks mediate symptoms in DI, but not in nonsomatic delusional disorders.
COVID-19 pandemic triggers surge in DI
Entomologist Gail E. Ridge, PhD, has taken notes on all of her thousands of consultations with individuals with suspected DI since the late 1990s. A sharp jump in such contacts occurred during the Great Recession of 2008 in conjunction with the widespread social distress of job loss and threatened economic ruin. Now the same thing is happening as the catastrophic COVID-19 pandemic stretches on. Indeed, during the first 8 months of the pandemic she documented 500 interactions involving people with suspected DI. She’s learned to identify the clues, including a chattering mind, defensiveness, physician avoidance, and rigid body tension.

“They’re fearful of judgment and suggestions of madness. And they’ll pounce on any perceived negativity. I never debunk beliefs; that can immediately backfire. If the medical profession was educated about DI, then many cases could be caught early. I, as the entomologist, and the mental health professionals are often last in line to be seen,” said Dr. Ridge, director of the Insect Information Office at the Connecticut Agricultural Experiment Station in New Haven.
She has noticed a recurring theme in her interactions with these patients: DI often starts with a real underlying medical condition, such as, for example, a cutaneous drug reaction, which over time, progresses to gain a psychiatric component. And she has found that a tipping point often occurs after roughly 6 months of unrelieved symptoms and sensations. Prior to that, affected individuals are concerned about their condition and will seek medical help in a genuine effort to understand what’s going on. They can be redirected. After about 6 months, however, Dr. Ridge has observed “they slide into the rabbit hole of fanaticism and despair.”
Arriving at the diagnosis
In the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), DI is classified as a “delusional disorder, somatic type 297.1 F22.” The diagnosis requires that the delusion be present for at least 1 month, criteria for schizophrenia are not met, and the condition cannot be attributed to other medical or neuropsychiatric conditions.
“Many of these people are very high-functioning. I have corporate CEOs who fly in to see me in their private jets. At work, they’re king of their domain. At home, their family is falling apart because of their delusion,” said Dirk M. Elston, MD, professor and chair of the department of dermatology and dermatologic surgery at the Medical University of South Carolina, Charleston.
Dr. Dirk M. Elston
“These people suffer, and the people around them suffer,” he emphasized.
Dozens of medical conditions can cause intractable itching or biting sensations. Far and away at the top of the medical differential diagnosis is thyroid disease, given its high incidence and frequent presentation with anxiety and itch. Other possibilities that can readily be ruled out via lab tests include substance use – especially involving amphetamine/methamphetamine, cocaine, or opioids – liver or kidney disease, diabetes and other sources of peripheral neuropathy, polycythemia, dermatitis herpetiformis, and pemphigus, Dr. Elston said.
Scott A. Norton, MD, MPH, MSc, a dermatologist and preventive medicine specialist at the Uniformed Services University of the Health Sciences in Bethesda, Md., noted that a diagnosis of DI requires three elements: The presence of abnormal sensations in the skin, a patient’s tenacious conviction that the sensations are caused by an infestation, and a lack of supporting evidence for that conviction.
Dr. Scott A. Norton
Taking an accurate medical history can be a challenge in these patients because they are often so guarded. They won’t disclose that they’ve already seen other health care providers, or that they’ve been self-treating with OTC veterinary medicine products, such as high-dose topical or oral ivermectin. They’ll often even deny repeated scratching despite clear evidence to the contrary from the skin exam.
As a dermatologist, Dr. Norton considers his first task to be a search for evidence of an infestation. Scabies is usually the first diagnosis proposed to account for the uncomfortable skin sensations. The presentation can be subtle. While the classic teaching is that the telltale signs of infestation by Sarcoptes scabiei are burrows in the skin and a rash in the web spaces between the fingers, he finds these features are often absent or equivocal.
“I think there are two more reliable presentations of scabies: Check to see if there’s symmetric involvement of the volar or palm side of the wrists; if there isn’t, I’m skeptical of the diagnosis. And every male older than 1 year of age with scabies will have scabies nodules on their genitalia. If the penis, the glans, or the scrotum aren’t involved with the nodules, I discard scabies as a possible diagnosis and look for evidence of other skin conditions that can plausibly explain the sensations and skin lesions, like eczema, contact dermatitis, scalp folliculitis, or dry skin,” he said.
If he can’t find evidence of infestation, he next systematically looks for another dermatologic cause of the patient’s sensations. When that proves fruitless, he tries to determine if there might be a biomedical or neuropsychiatric cause, such as depression, anxiety, schizophrenia, or dementia.
Taking a personal hygiene history is helpful. Patients who believe they have an infestation may bathe or shower three to five times daily with harsh soaps, causing dry, inflamed, itchy and uncomfortable skin.
“Many patients are thrilled to hear the good news that the history, physical examination, and lab tests do not show an infestation and that we have another explanation to account for their unwanted sensations. However, there are some patients who vehemently reject that idea and immediately return to their unwavering, unalterable belief that they are in fact infested. At this point, the possible diagnosis of DI looms large,” the dermatologist said.
Clues suggestive of DI include a patient’s obsessive focus on collecting “specimens” of the offending pathogen in Ziplock bags for assessment during the office visit – “usually a mix of unhelpful household debris and environmental detritus” – and eager presentation of a lengthy and detailed infestation diary, Dr. Norton said.
“Among the most distinctive signs that the patient is detached from reality are the biologically implausible descriptions and explanations of the supposed attacking organism. It’s a fanciful amalgamation of mutable features, behaviors, and life cycles composed of a composite of taxonomically unrelated organisms – for example, fungal hyphae with wings – that shapeshift at will to evade detection,” he said.
Dr. Elston observed that DI skin lesions are typically excoriated, sometimes because of a patient’s systematic use of a sharp object in an effort to dig out the infestation.
“One of the clues is the angularity of the lesion,” the dermatologist noted. “We always say round-to-oval lesions suggest an inside job; angulated lesions suggest an outside job, like fingernail work. There’s often a row of good healing border showing there’s really nothing wrong with wound healing, but a fibrinoid base where the excoriations have occurred. And the lesions are often in various stages of healing.”
Don’t forget neuropathic itch in nondelusional individuals as a potential cause of sensations of infestation and self-injury due to relentless scratching, urged Anne Louise Oaklander, MD, PhD, associate professor of neurology, Harvard Medical School, Boston, who is director of the nerve unit and the neurodiagnostic skin biopsy lab at Massachusetts General Hospital, Boston.
Dr. Anne Louise Oaklander
“There’s no one cause of patients’ impressions that they may have insects. Let’s be sympathetic: It is a normal assumption that insects may be present if the skin itches. One problem is that when patients don’t get good medical diagnoses they make up their own explanations, and sometimes these include persistent ideas of infestation. Many of them don’t realize that their scratching is a cause, not a result, of their skin lesions,” said Dr. Oaklander, who has conducted pioneering research on unintentional self-injury due to neuropathic itch accompanied by loss of pain signaling.
“Rapport first, medication later”
“The office visits are typically difficult to conclude, but skills can be learned and make it much easier to help these people,” Dr. Elston said.
John Koo, MD, emphasized that establishing rapport is “by far” the most important part of managing patients with DI.
Dr. John Koo
“Rapport first, medication later. This may require multiple visits,” said Dr. Koo, professor of dermatology at the University of California, San Francisco, who is a board-certified psychiatrist.
He makes sure he walks into the examination room all smiles and positivity. Patients with DI are eager to expound on their ailment; he lets them talk for a while, then when the timing is right, he actively encourages them to shift their focus away from etiology to treatment.
Dr. Koo and coworkers have described a spectrum of mental fixation in DI ranging from having only crawling and biting sensations, progressing to holding an overvalued idea as to their cause, then on to DSM-5 somatic preoccupation, followed by becoming truly delusional, and finally terminal delusion, where the patient doesn’t care about getting better, but only wants the physician to agree there is an infestation (J Clin Exp Dermatol Res. 2014 Oct. 3. doi: 10.4172/2155-9554.1000241).
“You cannot argue with people with delusions. How you talk to them as a clinician depends on whether they are entirely delusional or not,” he advised. “I cannot agree with their ideation, but I can agree with their misery – and that’s how I make a connection.”
Declining a DI patient’s request for a skin biopsy when it’s obvious there is no infestation can lead to a counterproductive power struggle. Instead, Dr. Koo turns the patient request into an opportunity to form a verbal contract: “I ask, ‘If the result comes back negative, can you be open-minded about the possibility of other etiologies besides parasites?’ ”
As for Dr. Norton, when his schedule shows a patient is coming in for a first visit for a supposed skin infestation, he tells his staff to expect a lengthy session as he works at establishing a good relationship.
“When my patients arrive with bags of specimens, I ask them to select two or three that they’re most confident will have a creature in them. Then I bring a two-headed microscope into the exam room and ask the patient to join me in examining the material. It helps with rapport by showing that I genuinely want to determine if there’s an infestation,” he explained.
He then sends the specimens to a laboratory, which provides a full report of the findings.
In performing a skin biopsy in a patient with suspected DI, Dr. Norton routinely biopsies two sites so the patient can’t claim sampling error when the pathology report comes back with no pathogens or parasites found. Also, he asks the patient to choose biopsy sites with intact skin where he or she believes the infestation exists. There is no point in biopsying excoriated lesions because they often contain snagged textile fibers.
Another rapport-building strategy: “I try to design a treatment regimen that will palliate the uncomfortable sensations and help relieve the patient’s misery while we continue working towards treating those delusions,” Dr. Norton said.
This might entail cutting back to one lukewarm shower per day with gentle or no soap, coupled with moisturizing, oral antihistamines or doxepin for itch, topical corticosteroids for the associated inflammation, and oral or topical antibiotics for any secondary bacterial skin infection.
What he doesn’t recommend as a rapport-building strategy or simply in order to get the patient out of the office is offering a therapeutic trial of an antiparasitic agent. That’s counterproductive. It may reinforce the false belief of infestation, and when the medication doesn’t bring lasting belief, the patient may conclude the infestation is resistant to conventional treatment.
Dr. Koo tells affected patients that he suspects they have Morgellons syndrome. He doesn’t call it DI in their presence.
“These people would not like their condition to be called delusional,” he explained. “Morgellons is a more neutral term. I tell them it’s a mysterious condition, and that what I’m really interested in is in trying to get them out of their misery.”
Treatment tips
Dr. Koo’s first-line medication for DI is pimozide (Orap), which in the United States has the advantage of being approved only for Tourette syndrome; it’s an antipsychotic without the perceived stigma of a psychiatric indication.
“Many of these patients will not consider taking any medication that has any psychiatric indication,” he noted.
Low-dose pimozide is highly effective, according to Dr. Koo, who recommends starting at 0.5 mg to 1 mg/day, increasing by 0.5 mg/day every 2-4 weeks. The drug is usually effective at a dose of 3 mg/day or less. Once a patient’s symptoms become clear or almost clear, the patient is maintained on that dose for another 3-4 months, then tapered by 0.5 mg/day every 2-4 weeks.
“In 35 years of seeing a new patient on average every week or two, I’ve had only five patients with one recurrence and one patient with two recurrences. All six responded to repeat therapy,” Dr. Koo said.
Side effects at these low doses are “very rare,” he added. Diphenhydramine (Benadryl) at 25 mg up to four times daily is effective for complaints of stiffness or restlessness. Prolongation of the QT interval is a potential concern, but Dr. Koo has never encountered it despite routinely ordering ECGs for patients on pimozide with known heart disease or who are over age 50.
When a patient can’t tolerate pimozide, Dr. Koo’s second-line antipsychotic for DI is low-dose risperidone (Risperdal), which is also highly effective.
Dr. Lepping noted that the European situation is different. There, unlike in the United States, pimozide has regulatory approval as an antipsychotic, so it loses the advantage of being an under-the-radar neuroleptic. His go-to medication is the first-generation antipsychotic sulpiride (Dogmatil), which he finds has a more favorable side effect profile than pimozide, particularly in the elderly. (Sulpiride is not approved in the United States.)
In treating DI, he prefers more dopaminergic-focused antipsychotics over those covering a broader spectrum of receptors. His alternatives to sulpiride include risperidone and olanzapine, atypical antipsychotics. He explains to patients that just as aspirin is used in low doses for its antiplatelet effect and in higher doses for pain relief, these medications can help them feel better at much lower doses than for schizophrenia.
“Once we get some rapport and a trusting relationship going, we normally try to persuade people to basically try something against their better judgment. We know that they don’t believe in it, but you try to get them to at least try something because everything else has failed,” Dr. Lepping explained. “We tell them it’s a condition we have seen before, and we have seen these medications to be useful because they are good for their distress, they help with making them calmer, and they might help with their symptoms. We say, ‘What do you have to lose if you trust us?’
“About 60% of our patients take the medication and almost invariably they all get better,” the psychiatrist said. “The others we either lose to follow-up or they just refuse to take the medication.”
A patient’s first visit to the Liverpool multispecialty DI referral clinic is 1 hour long. “They know that in advance, and we very much stick to that hour. We say to people up front, ‘We have an hour – that’s a lot, but we don’t have more,’ ” he said.

As a dermatologist, Dr. Norton considers his first task to be a search for evidence of an infestation. Scabies is usually the first diagnosis proposed to account for the uncomfortable skin sensations. The presentation can be subtle. While the classic teaching is that the telltale signs of infestation by Sarcoptes scabiei are burrows in the skin and a rash in the web spaces between the fingers, he finds these features are often absent or equivocal.
“I think there are two more reliable presentations of scabies: Check to see if there’s symmetric involvement of the volar or palm side of the wrists; if there isn’t, I’m skeptical of the diagnosis. And every male older than 1 year of age with scabies will have scabies nodules on their genitalia. If the penis, the glans, or the scrotum aren’t involved with the nodules, I discard scabies as a possible diagnosis and look for evidence of other skin conditions that can plausibly explain the sensations and skin lesions, like eczema, contact dermatitis, scalp folliculitis, or dry skin,” he said.
If he can’t find evidence of infestation, he next systematically looks for another dermatologic cause of the patient’s sensations. When that proves fruitless, he tries to determine if there might be a biomedical or neuropsychiatric cause, such as depression, anxiety, schizophrenia, or dementia.
Taking a personal hygiene history is helpful. Patients who believe they have an infestation may bathe or shower three to five times daily with harsh soaps, causing dry, inflamed, itchy and uncomfortable skin.
“Many patients are thrilled to hear the good news that the history, physical examination, and lab tests do not show an infestation and that we have another explanation to account for their unwanted sensations. However, there are some patients who vehemently reject that idea and immediately return to their unwavering, unalterable belief that they are in fact infested. At this point, the possible diagnosis of DI looms large,” the dermatologist said.
Clues suggestive of DI include a patient’s obsessive focus on collecting “specimens” of the offending pathogen in Ziplock bags for assessment during the office visit – “usually a mix of unhelpful household debris and environmental detritus” – and eager presentation of a lengthy and detailed infestation diary, Dr. Norton said.
“Among the most distinctive signs that the patient is detached from reality are the biologically implausible descriptions and explanations of the supposed attacking organism. It’s a fanciful amalgamation of mutable features, behaviors, and life cycles composed of a composite of taxonomically unrelated organisms – for example, fungal hyphae with wings – that shapeshift at will to evade detection,” he said.
Dr. Elston observed that DI skin lesions are typically excoriated, sometimes because of a patient’s systematic use of a sharp object in an effort to dig out the infestation.
“One of the clues is the angularity of the lesion,” the dermatologist noted. “We always say round-to-oval lesions suggest an inside job; angulated lesions suggest an outside job, like fingernail work. There’s often a row of good healing border showing there’s really nothing wrong with wound healing, but a fibrinoid base where the excoriations have occurred. And the lesions are often in various stages of healing.”
Don’t forget neuropathic itch in nondelusional individuals as a potential cause of sensations of infestation and self-injury due to relentless scratching, urged Anne Louise Oaklander, MD, PhD, associate professor of neurology, Harvard Medical School, Boston, who is director of the nerve unit and the neurodiagnostic skin biopsy lab at Massachusetts General Hospital, Boston.
Dr. Anne Louise Oaklander
“There’s no one cause of patients’ impressions that they may have insects. Let’s be sympathetic: It is a normal assumption that insects may be present if the skin itches. One problem is that when patients don’t get good medical diagnoses they make up their own explanations, and sometimes these include persistent ideas of infestation. Many of them don’t realize that their scratching is a cause, not a result, of their skin lesions,” said Dr. Oaklander, who has conducted pioneering research on unintentional self-injury due to neuropathic itch accompanied by loss of pain signaling.
“Rapport first, medication later”
“The office visits are typically difficult to conclude, but skills can be learned and make it much easier to help these people,” Dr. Elston said.
John Koo, MD, emphasized that establishing rapport is “by far” the most important part of managing patients with DI.
Dr. John Koo
“Rapport first, medication later. This may require multiple visits,” said Dr. Koo, professor of dermatology at the University of California, San Francisco, who is a board-certified psychiatrist.
He makes sure he walks into the examination room all smiles and positivity. Patients with DI are eager to expound on their ailment; he lets them talk for a while, then when the timing is right, he actively encourages them to shift their focus away from etiology to treatment.
Dr. Koo and coworkers have described a spectrum of mental fixation in DI ranging from having only crawling and biting sensations, progressing to holding an overvalued idea as to their cause, then on to DSM-5 somatic preoccupation, followed by becoming truly delusional, and finally terminal delusion, where the patient doesn’t care about getting better, but only wants the physician to agree there is an infestation (J Clin Exp Dermatol Res. 2014 Oct. 3. doi: 10.4172/2155-9554.1000241).
“You cannot argue with people with delusions. How you talk to them as a clinician depends on whether they are entirely delusional or not,” he advised. “I cannot agree with their ideation, but I can agree with their misery – and that’s how I make a connection.”
Declining a DI patient’s request for a skin biopsy when it’s obvious there is no infestation can lead to a counterproductive power struggle. Instead, Dr. Koo turns the patient request into an opportunity to form a verbal contract: “I ask, ‘If the result comes back negative, can you be open-minded about the possibility of other etiologies besides parasites?’ ”
As for Dr. Norton, when his schedule shows a patient is coming in for a first visit for a supposed skin infestation, he tells his staff to expect a lengthy session as he works at establishing a good relationship.
“When my patients arrive with bags of specimens, I ask them to select two or three that they’re most confident will have a creature in them. Then I bring a two-headed microscope into the exam room and ask the patient to join me in examining the material. It helps with rapport by showing that I genuinely want to determine if there’s an infestation,” he explained.
He then sends the specimens to a laboratory, which provides a full report of the findings.
In performing a skin biopsy in a patient with suspected DI, Dr. Norton routinely biopsies two sites so the patient can’t claim sampling error when the pathology report comes back with no pathogens or parasites found. Also, he asks the patient to choose biopsy sites with intact skin where he or she believes the infestation exists. There is no point in biopsying excoriated lesions because they often contain snagged textile fibers.
Another rapport-building strategy: “I try to design a treatment regimen that will palliate the uncomfortable sensations and help relieve the patient’s misery while we continue working towards treating those delusions,” Dr. Norton said.
This might entail cutting back to one lukewarm shower per day with gentle or no soap, coupled with moisturizing, oral antihistamines or doxepin for itch, topical corticosteroids for the associated inflammation, and oral or topical antibiotics for any secondary bacterial skin infection.
What he doesn’t recommend as a rapport-building strategy or simply in order to get the patient out of the office is offering a therapeutic trial of an antiparasitic agent. That’s counterproductive. It may reinforce the false belief of infestation, and when the medication doesn’t bring lasting belief, the patient may conclude the infestation is resistant to conventional treatment.
Dr. Koo tells affected patients that he suspects they have Morgellons syndrome. He doesn’t call it DI in their presence.
“These people would not like their condition to be called delusional,” he explained. “Morgellons is a more neutral term. I tell them it’s a mysterious condition, and that what I’m really interested in is in trying to get them out of their misery.”
Treatment tips
Dr. Koo’s first-line medication for DI is pimozide (Orap), which in the United States has the advantage of being approved only for Tourette syndrome; it’s an antipsychotic without the perceived stigma of a psychiatric indication.
“Many of these patients will not consider taking any medication that has any psychiatric indication,” he noted.
Low-dose pimozide is highly effective, according to Dr. Koo, who recommends starting at 0.5 mg to 1 mg/day, increasing by 0.5 mg/day every 2-4 weeks. The drug is usually effective at a dose of 3 mg/day or less. Once a patient’s symptoms become clear or almost clear, the patient is maintained on that dose for another 3-4 months, then tapered by 0.5 mg/day every 2-4 weeks.
“In 35 years of seeing a new patient on average every week or two, I’ve had only five patients with one recurrence and one patient with two recurrences. All six responded to repeat therapy,” Dr. Koo said.
Side effects at these low doses are “very rare,” he added. Diphenhydramine (Benadryl) at 25 mg up to four times daily is effective for complaints of stiffness or restlessness. Prolongation of the QT interval is a potential concern, but Dr. Koo has never encountered it despite routinely ordering ECGs for patients on pimozide with known heart disease or who are over age 50.
When a patient can’t tolerate pimozide, Dr. Koo’s second-line antipsychotic for DI is low-dose risperidone (Risperdal), which is also highly effective.
Dr. Lepping noted that the European situation is different. There, unlike in the United States, pimozide has regulatory approval as an antipsychotic, so it loses the advantage of being an under-the-radar neuroleptic. His go-to medication is the first-generation antipsychotic sulpiride (Dogmatil), which he finds has a more favorable side effect profile than pimozide, particularly in the elderly. (Sulpiride is not approved in the United States.)
In treating DI, he prefers more dopaminergic-focused antipsychotics over those covering a broader spectrum of receptors. His alternatives to sulpiride include risperidone and olanzapine, atypical antipsychotics. He explains to patients that just as aspirin is used in low doses for its antiplatelet effect and in higher doses for pain relief, these medications can help them feel better at much lower doses than for schizophrenia.
“Once we get some rapport and a trusting relationship going, we normally try to persuade people to basically try something against their better judgment. We know that they don’t believe in it, but you try to get them to at least try something because everything else has failed,” Dr. Lepping explained. “We tell them it’s a condition we have seen before, and we have seen these medications to be useful because they are good for their distress, they help with making them calmer, and they might help with their symptoms. We say, ‘What do you have to lose if you trust us?’
“About 60% of our patients take the medication and almost invariably they all get better,” the psychiatrist said. “The others we either lose to follow-up or they just refuse to take the medication.”
A patient’s first visit to the Liverpool multispecialty DI referral clinic is 1 hour long. “They know that in advance, and we very much stick to that hour. We say to people up front, ‘We have an hour – that’s a lot, but we don’t have more,’ ” he said.
The initial visit is typically followed by two to four 30-minute follow-up visits. Dr. Lepping recommends that when possible, patients with DI should be seen jointly by a psychiatrist and a nonpsychiatrist physician. He finds this approach leads to substantially better clinical outcomes than with a single health care provider.
“If you have two people in the clinic with the patient, when you get really annoyed and your amygdala really starts going, that’s the time when you can then turn to your colleague and say, ‘Oh yes, and Professor Squire, what do you have to say to that?’ So as you see the red mist rising in yourself because you’re getting so exasperated, you have the other person there to take over so you can calm down. And then the other person does the same. That can be really important to deescalate a heated situation,” Dr. Lepping explained.
Roughly 10% of patients with DI have what is termed folie à deux, where the delusion of infestation is shared by another person.
“Anecdotally, I would say those are much more difficult to treat,” said Jason S. Reichenberg, MD, MBA, professor of medicine (dermatology) at the University of Texas at Austin and president of the Ascension Medical Group Texas.
Dr. Jason S. Reichenberg
“It’s like getting somebody to quit smoking when everybody else in the house is still smoking. It’s very hard to convince a single family member that they’re wrong when everybody else in their family keeps telling them they’re right,” he said.
Recent advances in DI research
Dr. Lepping and coinvestigators at multispecialist DI clinics in London, Italy, and Moscow reported in an unusually large observational study of 236 affected patients that longer duration of untreated psychosis was associated with significantly worse clinical outcome. It’s a finding consistent with Dr. Koo’s construct of progressive stages of delusionality, and it underscores the need for early treatment.
“Having said that, improvement is still possible, even if people have had quite a long time of untreated psychosis,” Dr. Lepping said. The same study also showed that older age at illness onset was inversely associated with good outcome.
In another study, Dr. Lepping and colleagues reported that substance use involving amphetamines, cocaine, opioids, and other drugs that can cause itch was roughly twice as common in a group of patients with DI compared to the general population. “I highly recommend, if at all possible, a drug screen in suspected DI,” he said.
In a large survey of U.S. and Canadian veterinarians, Dr. Lepping and coinvestigators found that these practitioners not infrequently encountered delusional infestation among pet owners who claimed their dog or cat is infested when it’s not. This is called “delusion by proxy,” and it often leads to unwarranted animal euthanasia. Some of these pet owners claim they, too, are infested, which the investigators termed “double delusional infestation.”
MRI studies
Recent structural brain MRI studies support the concept that impaired somatosensory neural networks mediate the delusional symptoms of DI, but not in delusional disorders without somatic content. This was demonstrated in an MRI study by Dr. Lepping and others conducted in 18 patients with DI, 19 others with nonsomatic delusional disorders centered on themes of persecution or jealousy, and 20 healthy volunteers. The DI group had lower gray matter volume in prefrontal, thalamic, striatal, and insular regions of the brain compared to the other two groups.
Of note, mapping of the insula and dorsal striatum indicates they are part of the peripersonal space network, which integrates tactile and visual perceptions involving the area near the body surface. The insula also mediates feelings of pain and disgust.
Some of the same investigators have also recently reported brain MRI evidence specifically of cerebellar dysfunction in patients with DI, who displayed decreased gray matter volume in left lobule VIIa of the cerebellum and increased gray matter volume in bilateral lobule VIIa/crus II compared to patients with non-somatic delusions. This points to a role for impaired cerebellar neural networks related to somatosensory perception in patients with DI but not in those with non-somatic delusions.
Delusional infestation: What’s in a name?
Ekbom syndrome. Delusional parasitosis. Morgellons syndrome. These and other terms are increasingly giving way to ‘delusional infestation’ as the preferred moniker for the disorder. That’s in part because the delusional focus in patients with this condition has shifted over time. In the 19th century, for example, affected patients often attributed their infestation to typhus.
In contemporary practice, roughly one-quarter of affected patients think they are infested by small inanimate objects, most commonly fibers or threads emerging from the skin, rather than by parasites, insects, or worms. In a study of 148 consecutive European patients with suspected DI, Dr. Lepping and coinvestigators reported only 35% believed they were infested by parasites.
“The name ‘delusional infestation’ emphasizes the constantly changing pathogens and covers all present and future variations of the theme that are bound to occur,” Dr. Lepping observed.

Adolescents and young adults with mood disorders and cannabis use disorder (CUD) are at significantly increased risk for self-harm, all-cause mortality, homicide, and death by unintentional overdose, new research suggests.
Dr. Cynthia Fontanella
Investigators found the risk for self-harm was three times higher, all-cause mortality was 59% higher, unintentional overdose was 2.5 times higher, and homicide was more than three times higher in those with versus without CUD.
“The take-home message of these findings is that we need to be aware of the perception that cannabis use is harmless, when it’s actually not,” lead author Cynthia Fontanella, PhD, associate professor of psychiatry, Ohio State University Wexner Medical Center, Columbus, said in an interview.
“We need to educate parents and clinicians that there are risks associated with cannabis, including increased risk for self-harm and death, and we need to effectively treat both cannabis use disorder and mood disorders,” she said.
The study was published online Jan. 19, 2021, in JAMA Pediatrics.
Little research in youth
“There has been very little research conducted on CUD in the adolescent population, and most studies have been conducted with adults,” Dr. Fontanella said.
Research on adults has shown that, even in people without mood disorders, cannabis use is associated with the early onset of mood disorders, psychosis, and anxiety disorders and has also been linked with suicidal behavior and increased risk for motor vehicle accidents, Dr. Fontanella said.

“We were motivated to conduct this study because we treat kids with depression and bipolar disorder and we noticed a high prevalence of CUD in this population, so we were curious about what its negative effects might be,” Dr. Fontanella recounted.
The researchers analyzed 7-year data drawn from Ohio Medicaid claims and linked to data from death certificates in 204,780 youths between the ages of 10 and 24 years (mean age was 17.2 years at the time of mood disorder diagnosis). Most were female, non-Hispanic White, enrolled in Medicaid because of poverty, and living in a metropolitan area (65.0%, 66.9%, 87.6%, and 77.1%, respectively).
Participants were followed up to 1 year from diagnosis until the end of enrollment, a self-harm event, or death.
Researchers included demographic, clinical, and treatment factors as covariates.
Close to three-quarters (72.7%) of the cohort had a depressive disorder, followed by unspecified/persistent mood disorder and bipolar disorder (14.9% and 12.4%, respectively). Comorbidities included ADHD (12.4%), anxiety disorder (12.3%), and other mental disorders (13.1%).
One -tenth of the cohort (10.3%) were diagnosed with CUD.
CUD treatment referrals
“Although CUD was associated with suicide in the unadjusted model, it was not significantly associated in adjusted models,” the authors reported.
Dr. Fontanella noted that the risk for these adverse outcomes is greater among those who engage in heavy, frequent use or who use cannabis that has higher-potency tetrahydrocannabinol (THC) content.
Reasons why CUD might be associated with these adverse outcomes are that it can increase impulsivity, poor judgment, and clouded thinking, which may in turn increase the risk for self-harm behaviors, she said.
She recommended that clinicians refer youth with CUD for “effective treatments,” including family-based models and individual approaches, such as cognitive behavioral therapy and motivational enhancement therapy.
Open dialogue
In a comment, Wilfrid Noel Raby, MD, PhD, adjunct clinical professor, Albert Einstein College of Medicine, New York, noted that psychosis can occur in patients with CUD and mood disorders – especially bipolar disorder – but was not included as a study outcome. “I would have liked to see more data about that,” he said.
However, a strength of the study was that it included children aged as young as 10 years. “The trend is that cannabis use is starting at younger and younger ages, which has all kinds of ramifications in terms of cerebral development.”
Christopher Hammond, MD, PhD, assistant professor of psychiatry, Johns Hopkins University, Baltimore, said: “Three major strengths of the study are the size of the sample, its longitudinal analysis, and that the authors controlled for a number of potential confounding variables.”
In light of the findings, Dr. Hammond recommended clinicians and other health professionals who work with young people “should screen for cannabis-related problems in youth with mood disorders.”
Dr. Hammond, who is the director of the Co-occurring Disorders in Adolescents and Young Adults Clinical and Research Program, Johns Hopkins Bayview Medical Center, Baltimore, and was not involved with the study, recommended counseling youth with mood disorders and their parents and families “regarding the potential adverse health effects related to cannabis use.”
He also recommended “open dialogue with youth with and without mental health conditions about misleading reports in the national media and advertising about cannabis’ health benefits.”
The study was funded by the National Institute of Mental Health. Dr. Fontanella reported receiving grants from the National Institute of Mental Health during the conduct of the study. Dr. Raby reported no relevant financial relationships. Dr. Hammond reported receiving research grant funding from the National Institutes of Health, the American Academy of Child & Adolescent Psychiatry, Substance Abuse Mental Health Services Administration, the National Network of Depression Centers, and the Armstrong Institute at Johns Hopkins Bayview and serves as a scientific adviser for the National Courts and Science Institute and as a subject matter expert for SAMHSA related to co-occurring substance use disorders and severe emotional disturbance in youth.

The Food and Drug Administration has extended the review period for aducanumab, the investigational amyloid-clearing treatment for Alzheimer’s disease, by 3 months, the drug’s manufacturers have announced. The updated prescription drug user fee act (PDUFA) action date has been pushed forward from March 7 to June 7, 2021.
“As part of the ongoing review, Biogen submitted a response to an information request by the FDA, including additional analyses and clinical data, which the FDA considered a major amendment to the application that will require additional time for review,” Biogen and Eisai said in a statement.
“We are committed to working with the FDA as it completes its review of the aducanumab application. We want to thank the FDA for its continued diligence during the review,” said Biogen CEO Michel Vounatsos.
Biogen submitted the aducanumab application for approval to the FDA in July 2020. The FDA accepted it in August and granted priority review.
Aducanumab is a recombinant human monoclonal antibody targeting beta-amyloid (Abeta). If approved, it would be the first disease-modifying treatment for Alzheimer’s disease.
However, the road to approval has been bumpy. In November, despite high expectations and pleas from patients, caregivers, and advocacy groups, an FDA advisory panel declined to recommend approval of aducanumab.
As previously reported by this news organization, members of the FDA’s Peripheral and Central Nervous System Drugs Advisory Committee determined that results from Biogen’s one large positive trial did not provide strong enough evidence of efficacy for the treatment of Alzheimer’s disease.

“We are committed to working with the FDA as it completes its review of the aducanumab application. We want to thank the FDA for its continued diligence during the review,” said Biogen CEO Michel Vounatsos.
Biogen submitted the aducanumab application for approval to the FDA in July 2020. The FDA accepted it in August and granted priority review.
Aducanumab is a recombinant human monoclonal antibody targeting beta-amyloid (Abeta). If approved, it would be the first disease-modifying treatment for Alzheimer’s disease.
However, the road to approval has been bumpy. In November, despite high expectations and pleas from patients, caregivers, and advocacy groups, an FDA advisory panel declined to recommend approval of aducanumab.
As previously reported by this news organization, members of the FDA’s Peripheral and Central Nervous System Drugs Advisory Committee determined that results from Biogen’s one large positive trial did not provide strong enough evidence of efficacy for the treatment of Alzheimer’s disease.

The Food and Drug Administration has extended the review period for aducanumab, the investigational amyloid-clearing treatment for Alzheimer’s disease, by 3 months, the drug’s manufacturers have announced. The updated prescription drug user fee act (PDUFA) action date has been pushed forward from March 7 to June 7, 2021.

The final numbers won’t look much different, but the 2021 Match results will be unlike any before. As of mid-January, only 16 more institutions were confirmed to be participating in Match Day this year, resulting in about 800 more positions, said Donna Lamb, president and CEO of the National Resident Matching Program (NRMP). The Electronic Residency Application Service reported about 50,000 individual applicant submissions, a slight increase from prior years.
The stats may be similar, but the current residency application cycle may lead to wildly different results after the pandemic forced interviews to be conducted virtually and caused the cancellation of most away clinical rotations. Troy Amen, a fifth-year MD-MBA student at Harvard Medical School, Boston, and copresident of his student class, says the lack of on-campus, in-person experiences means students feel more in the dark than ever. The same is true for institutions. “The programs are also suffering because now they don’t know which students are a good ‘cultural fit’ for them,” he said.
Standing out has always been a concern for prospective residents, but Mr. Amen says fears are even higher this year. “[Institutions are] struggling to vet out 850 applicants, and they have no connection to us.”
Organizations have scrambled to keep the process as fair and informative as possible. “Everyone is trying to do the right thing here,” said Alison J. Whelan, MD, chief academic officer of the Association of American Medical Colleges (AAMC). She says that although the process has significantly changed, the heart of it remains the same. “The bottom line is directors really want to fill their intern class, and schools and students really want to match.”
Since the NRMP was established in 1952, it has never had to contend with a pandemic of this scale. The unprecedented circumstances have led to some much-feared and some unexpected changes, like top candidates “stealing” interview slots, “swag bags” sent to entice residents, beefed-up online profiles, as well as “Zoom fatigue,” a spike in home-field advantage for institutions, and massive anxiety for those students staking their future to a city they may have never seen in person.
What was lost and what was gained
“It’s really hard to get a real feel for the program when you’ve not been there in person,” said Christopher Smith, MD, director of the internal medicine residency program at Beth Israel Deaconess Medical Center in Boston. Dr. Smith recalled interviewing for residencies 25 years ago. His wife, a teacher, took time off to travel with him.
“She would ‘interview the town’ while I interviewed the program, and we compared notes at night,” he said. Because of COVID-19-related travel restrictions, just physically seeing the city in which they may live for years wasn’t an option for many. “I have a lot of sympathy for students applying right now,” Dr. Smith said.
For the residency class of 2021, the first shoe really dropped last March, when the AAMC issued guidance strongly recommending that programs pause clinical rotations away from their home schools. As established doctors know well, and as graduating medical students confirmed, these rotations are crucial to understanding a program’s culture and gaining experience that can boost candidacy. “I’m applying to orthopedic surgery, where away rotations are the gold standard for impressing attendees and residents at institutions away from home,” said Mr. Amen.
The pandemic completely cut off that key source of information to determine the right fit. It also meant applicants couldn’t have as diverse a portfolio of recommendation letters, something many worry may be detrimental to their soon-to-be-released Match rankings.
Unlike the loss of away rotations, the forced shift from in-person to virtual interviews had some meaningful benefits. Students no longer incurred expenses for airline flights, hotel rooms, and rental cars. Many organizations and programs have been trying for years to figure out how to lower the financial burden of interviews to make the process more equitable for those at economic or other disadvantage.
“The equity piece of this is huge – decreasing barriers and leveling the field a little bit is a really huge advantage,” said Kate Shaw, MD, residency program director and associate chair of education for the obstetrics and gynecology program at Stanford (Calif.) University. In some ways, this latest change is an extension of a strategy Dr. Shaw and others had already begun implementing.
“Over the last 5 to 10 years, we’ve been working to address the implicit bias in the application process, so we’ve gone to a holistic review of applicants, where we don’t have score cutoffs. We look at the whole person,” she said. “And we did that in an effort to increase diversity and equity.” Dr. Shaw and others hope that the accidental positive changes from COVID restrictions may be intentionally preserved long after the pandemic ends.
Home-field advantage vs. swag bags
Many medical students applying to residencies this year say they have given greater weight to their home programs than they might have without the pandemic. “I didn’t get a sense of anyone’s culture other than my home institution,” said Alex Skidmore, a fourth-year medical student at Washington University in St. Louis. “I definitely am ranking Wash-U higher.”
The desire to emphasize the known quality of a student’s home institution isn’t surprising to program directors. Dr. Shaw said she thinks this year’s Match could well end with a higher percentage of students matching either in their home programs or in programs close to loved ones. “The value of being close to family has come up in our conversations, where students are considering the right program for them but also the other life factors,” she said.
To overcome this home-field advantage, many programs have beefed up their websites, including providing video tours of their facilities. They also “upped their social media game” and encouraged residents to create online groups for prospective residents to share information about programs and life outside of work. Some residents even offered video tours of their personal apartments to applicants.
Without in-person access to facilities and staff, a program’s online presence became a deciding factor, applicants said. “If you have a bad website, it’s like having a dirty building to interview applicants in,” Mr. Skidmore said. For many prospective residents, an institution’s Internet presence was a “make or break” factor. “It’s the only thing I saw for many programs, and when we are doing the amount of research we are doing remotely, when I saw a program with a bad website, it made me not like the program as much,” he said.
Some programs, hoping to woo candidates as well as to provide them with more insight into what they and their cities have to offer, sent “swag bags” to candidates. These included things like gift cards for food delivery and offerings from local businesses. Washington University’s pediatrics residency program sent gooey butter cakes – a St. Louis staple – along with other treats from small businesses and copies of magazines that showcased the city’s dining and entertainment scene.
Other programs, even those at the same medical institution, felt quite strongly that those types of packages shouldn’t be sent. “We interviewed almost 500 applicants, so there was no way we could have afforded that,” said Dominique Cosco, MD, director of Washington University’s internal medicine residency program. “Our normal recruitment budget is almost $100,000 in a normal year, and that got cut because of COVID. For us, it was thinking about allocations of resources.”
Interview slot theft and zoom fatigue
Remote interviewing also meant that applicants could accept more interviews, something that raised a big concern. Without expenses or travel time, would top-tier candidates take more interviews than normal and thus take limited interview spots from other qualified candidates? Maybe so, says the AAMC’s Dr. Whelan.
“We didn’t have systematic data, but we heard from enough schools and programs ... that students who were maybe not the top-top ranked students in the class but in every way solid were receiving fewer interviews than previous years,” Dr. Whelan said. This is despite guidance that recommended programs add interview slots to serve as a counterbalance.
Some students say they accepted more interview slots in the beginning of the interview season, partly because they could, and partly because some thought of early interviews as “practice” for later interviews. However, as video interviews piled up, some of them described feeling “Zoom fatigue” and said they later canceled interviews with programs they didn’t anticipate joining.
More SOAP, less clarity
As for what comes next, the NRMP is preparing for a longer-than-normal Supplemental Offer and Acceptance Program (SOAP) than in years past. SOAP usually offers three rounds of matches after the initial Match Day; Ms. Lamb said things are different this year.
“SOAP will be the same number of days, but we’ve added an additional round on Thursday afternoon,” she said. Will it be unnecessary or not enough? Nobody knows. “How big SOAP actually is going to be is one of the things that we really don’t have a sense of right now and probably aren’t going to have a sense of until the Match.”
Uncertainty is the name of the game. More than any other Match before, programs and applicants won’t know how results from this pandemic year stack up for a few months at the very least. “I really want to see what this looks like on the other side,” Dr. Smith said. “Are applicants happy with the way it looks when they come here? Do they feel like they matched with the right place?”
Whether this unprecedented year will be remembered more for positive changes moving forward, including more flexibility on remote interviews, or for less-informed decisions that result in dissatisfied participants is also unclear.
“I think after the Match is over, we’ll be talking to everyone to get more perspective on what people who are applying now would tell the next class, and how programs can adjust,” said Kathy Diemer, MD, assistant dean for career counseling at Washington University. At the very least, those who are involved in this year after year can start thinking about what the future should look like.
“We’re going to need to do some kind of debriefing after this is over, both program directors and our students as well, so we can determine how to move forward next year and beyond.”

Afternoon napping was associated with better cognition in an older Chinese population, according to a new study in General Psychiatry.
The findings add to those seen in other observational studies showing afternoon napping promotes cognitive function, said the authors of the paper, published in General Psychiatry.
“The prevalence of afternoon napping has been increasing in older adults much more than in younger individuals,” wrote Han Cai, MS, of the department of geriatrics at The Fourth People’s Hospital of Wuhu, Anhui, China, and coauthors. “The elderly individuals who took afternoon naps showed significantly higher cognitive performance compared with those who did not nap.”
The researchers enrolled 2,214 people in the study – all Han Chinese and aged 60 or older. Afternoon napping was considered any period of inactivity of at least 5 minutes but less than 2 hours after lunch and outside of the person’s main sleep schedule. Those who reported ever napping – 1,534 subjects – were included in the napping group, and the others – 680 – in the nonnapping group. Patients with major physical conditions were excluded.
The Montreal Cognitive Assessment (MoCA), the Mini-Mental State Examination (MMSE), and the Neuropsychological Test Battery (NTB) were used to measure cognitive function, and 739 patients agreed to blood tests for lipid values.
The average total MMSE score was higher for the napping group at 25.3 points out of 30, than for the nonnapping group, at 24.56 (P = .003). Those in the napping group also had significantly higher scores in the orientation portion of the MoCA test, at 5.55 out of 6 points, compared with 5.41 for the nonnapping group (P = .006).
Those in the napping group scored significantly higher on the digit span and language fluency parts of the Neuropsychological Test Battery (P = .009 and .020, respectively).
Dementia was assessed with face-to-face visits with clinicians, but diagnoses of dementia were not different between the groups.
Triglycerides were found to be higher – though still in the normal range – in the napping group compared with the nonnapping group, 1.80 mmol/L to 1.75 mmol/L, the researchers found (P = .001). No differences were seen for HDL or LDL cholesterol levels, or in hypertension or diabetes, the researchers reported.
The authors noted that inflammation is likely an important feature in the relationship between napping and cognitive function. Inflammatory cytokines have been found to play a role in sleep disorders, and strong inflammatory responses can lead to adverse events, including cognitive impairment.
“Sleep is known to be a regulator of the immune response that counters these inflammatory mediators, whereas napping, in particular, is thought to be an evolved response to inflammation,” they said.
The average age of patients in the napping group was 72.8 years, slightly older than those in the nonnapping group at 71.3 years, and this was a significant difference (P = .016).
The researchers acknowledged that the study “could not show direct causality of napping, whether beneficial or harmful,” and that “a lack of detailed information regarding napping duration ... also limited the description of napping status.”
Junxin Li, PhD, RN, assistant professor at Johns Hopkins School of Nursing, Baltimore, who has studied napping and cognition, said that previous research generally supports a U-shaped relationship between napping and mental acuity, with shorter or medium-length naps benefiting cognition and no naps or naps that are too long being detrimental.

“This study looked at no nap versus naps of less than 2 hours and may not be able to capture this potential U-shaped association,” she said.
For clinicians, the duration, timing, frequency, and purpose of naps are important factors in making recommendations to patients, she said.
“For example, timing – napping in the early evening close to older adult’s bedtime may delay their bedtime and interfere with their nighttime sleep quality. Taking naps after lunchtime is hypothesized to provide the most therapeutic values to the health and usually recommended,” she said. Regular napping is better than “randomly dozing off,” Dr. Li added.
There are also cultural considerations – in east Asia, napping tends to be considered part of a healthy lifestyle, while in western countries it is not – and this could impact napping behaviors and how these behaviors affect cognition, she said.
Phyllis C. Zee, MD, PhD, director of the Center for Circadian and Sleep Medicine at the Northwestern University, Chicago, said the results are consistent with early cross-sectional studies that showed that regular, scheduled naps in the afternoon were associated with positive cognitive performance and lower cardiometabolic disease risk.

Dr. Zee noted that it’s important to recognize that the positive data are associated with naps that are planned, while older adults napping because of excess sleepiness are at a higher risk for cognitive impairment and other health issues.

Afternoon napping was associated with better cognition in an older Chinese population, according to a new study in General Psychiatry.
The findings add to those seen in other observational studies showing afternoon napping promotes cognitive function, said the authors of the paper, published in General Psychiatry.
“The prevalence of afternoon napping has been increasing in older adults much more than in younger individuals,” wrote Han Cai, MS, of the department of geriatrics at The Fourth People’s Hospital of Wuhu, Anhui, China, and coauthors. “The elderly individuals who took afternoon naps showed significantly higher cognitive performance compared with those who did not nap.”
The researchers enrolled 2,214 people in the study – all Han Chinese and aged 60 or older. Afternoon napping was considered any period of inactivity of at least 5 minutes but less than 2 hours after lunch and outside of the person’s main sleep schedule. Those who reported ever napping – 1,534 subjects – were included in the napping group, and the others – 680 – in the nonnapping group. Patients with major physical conditions were excluded.
The Montreal Cognitive Assessment (MoCA), the Mini-Mental State Examination (MMSE), and the Neuropsychological Test Battery (NTB) were used to measure cognitive function, and 739 patients agreed to blood tests for lipid values.
The average total MMSE score was higher for the napping group at 25.3 points out of 30, than for the nonnapping group, at 24.56 (P = .003). Those in the napping group also had significantly higher scores in the orientation portion of the MoCA test, at 5.55 out of 6 points, compared with 5.41 for the nonnapping group (P = .006).
Those in the napping group scored significantly higher on the digit span and language fluency parts of the Neuropsychological Test Battery (P = .009 and .020, respectively).
Dementia was assessed with face-to-face visits with clinicians, but diagnoses of dementia were not different between the groups.
Triglycerides were found to be higher – though still in the normal range – in the napping group compared with the nonnapping group, 1.80 mmol/L to 1.75 mmol/L, the researchers found (P = .001). No differences were seen for HDL or LDL cholesterol levels, or in hypertension or diabetes, the researchers reported.

Areas with active cannabis dispensaries have seen a decrease in opioid-related mortalities, recent research has shown.
Dr. Greta Hsu
“Our findings suggest that higher storefront cannabis dispensary counts are associated with reduced opioid related mortality rates at the county level,” wrote Greta Hsu, PhD, professor of management, University of California, Davis, and Balázs Kovács, PhD, associate professor of organizational behavior, Yale University, New Haven, Conn. “This association holds for both medical and recreational dispensaries, and appears particularly strong for deaths associated with synthetic (nonmethadone) opioids, which include the highly potent synthetic opioid fentanyl and its analogs.”
Dr. Balázs Kovács
In the study, published in BMJ, the researchers evaluated the prevalence of medical and recreational cannabis dispensaries in 812 U.S. counties within 23 states with some degree of cannabis legalization between 2014 and 2018. Overall, dispensaries located in counties in eight U.S. states and the District of Columbia that sold cannabis recreationally and an additional 15 states that contained medical cannabis dispensaries were included.
Dr. Hsu and Dr. Kovács performed their analysis by examining dispensaries that were operating storefronts by the end of 2017 at the county level using panel-regression methods, combining data obtained from the consumer-facing website Weedmaps.com, Centers for Disease Control and Prevention U.S. mortality data, and data from the U.S. Census Bureau.
To measure opioid-related mortality, the researchers measured ICD-10 codes specific to natural opioid analgesics and semisynthetic opioids, methadone, heroin, nonmethadone synthetic opioid analgesics, and fentanyl-related deaths.
The analysis showed a negative association between the number of cannabis dispensaries at the county level and overall opioid-related mortality rates (95% confidence interval, −0.23 to −0.11), with an increase from one to two dispensaries in a county resulting in a 17% decrease in opioid-related mortality rates and an increase from two to three dispensaries resulting in another decrease in opioid-related mortality of 8.5%.
When evaluating mortality by specific opioid type, the researchers found a negative association between the number of dispensaries and synthetic nonmethadone opioids, with an increase from one to two dispensaries resulting in a 21% decrease in mortality attributable to synthetic nonmethadone opioids (95% CI, −0.27 to −0.14; P = .002). There were also negative associations between the number of dispensaries and prescription opioid-related mortality rates (95% CI, −0.13 to −0.03) and heroin-related mortality rates (95% CI, −0.13 to −0.02). The negative association was similar in comparisons between synthetic nonmethadone opioid-related mortality and the number of dispensaries for medical cannabis (95% CI, −0.21 to −0.09; P = .002) and recreational cannabis (95% CI, −0.17 to −0.04; P = .01).
Evidence of a negative association between legalization of medical or recreational cannabis and opioid-related mortality has been mixed in the literature, with some studies also showing a “spurious or nonsignificant” association, according to Dr. Hsu and Dr. Kovács.
While previous studies have looked at the legalization of cannabis for medical or recreational use, legalization on its own is an “incomplete picture,” they said, which might offer one explanation for these mixed findings. Some states that legalize medical cannabis, for example, might not allow dispensaries to legally sell cannabis, and there may be a delay of 1-2 years between the time a state legalizes cannabis for recreational use and when dispensaries are open and available to the public.
“These results were obtained after controlling for county level population characteristics, yearly effects, whether recreational dispensaries were legal or not in the focal county’s state, and opioid-related state policies,” the authors wrote.
Results ‘may be even stronger’ than reported
Christopher G. Fichtner, MD, clinical professor of psychiatry and neuroscience at the University of California, Riverside, said in an interview that the evidence for using cannabis as an opioid substitution for pain management has not been balanced, but noted “the bulk of it suggests that there is some harm reduction benefit by having liberalized access to cannabis.”

One strength of the study by Dr. Hsu and Dr. Kovács was how they were able to examine implementation of legalization of medical or recreational cannabis, rather than simply a change in the law, he said.
“By looking at dispensary count, it’s actually looking at a better measure of on-the-ground implementation than just change in policy,” Dr. Fichtner explained. “You’re looking at what was actually accomplished in terms of making cannabis legally available.”
The choice to evaluate storefront dispensaries only and not include delivery services in their data, “probably makes it a relatively conservative estimate. I think that would be a strength, that their findings may be even stronger than what it is they’re reporting,” Dr. Fichtner said.
“I do think, if anything, the paper is relatively tentative about advancing its conclusions, which I think is a weakness in a lot of these studies,” he added. In 2017, the National Academy of Sciences released a report that found evidence cannabis or cannabinoids can significantly reduce pain symptoms. In that report, “one of their strongest conclusions is that there’s conclusive or substantial evidence that cannabis or cannabinoids are effective management of chronic pain,” Dr. Fichtner said.
He said that digging deeper into what kinds of pain cannabis can treat is one area for future research. “Certainly, it seems that it’s unlikely that cannabis is going to be good for every kind of pain,” he said. “What kinds of pain is it better for than others? Is it some benefit for many kinds of pain, or only a few types of pain?”
The authors reported no relevant financial disclosures. Dr. Fichtner is the author of a book on cannabis policy in the United States, but reported no other financial disclosures.
