INDIANAPOLIS – Despite the common prevalence of skin-picking disorder and trichotillomania (hair pulling), no Food and Drug Administration–approved treatments exist for either condition.

And while both body-focused repetitive behavior disorders affect a greater proportion of females than males, “we have no current information that is useful about what hormonal influences may or may not play in terms of picking and pulling behaviors,” Jon E. Grant, MD, JD, MPH, professor of psychiatry and behavioral neuroscience at the University of Chicago, said at the annual meeting of the Society for Pediatric Dermatology. “On a cognitive level, affected children and adolescents often have impaired inhibitory control but they are often 1-2 standard deviations above average IQ. They have Type A personalities [and are] very driven young kids. They also do not tolerate any down time or boredom. They need to be doing something all the time.”

According to the DSM-5, the diagnostic criteria for skin picking includes recurrent skin picking that results in skin lesions and is not attributable to another medical condition or substance. It also involves repeated attempts to decrease or stop the behavior and causes clinically significant distress or impairment.

“The other medical condition that we are interested in is the misuse of or dependence upon amphetamines or other prescription-based or illicit stimulants,” Dr. Grant said. “I saw a young man who was using about 600 mg of Ritalin a day, and he was picking all over the place. He did not have a primary skin disorder.”

The lifetime prevalence of skin picking disorder ranges between 1.4% and 5.4% of the general population. However, about 63% of people in a community sample endorsed some form of skin picking, and in a study of 105 college students, almost 40% said they picked their skin and had noticeable tissue damage as a result.

“Skin picking is not the same as self-injury,” Dr. Grant said. “It is also not simply an anxiety disorder. Anxiety will make people who pick worse, so people will say that they pick when they’re under stress. I can give them benzodiazepines and they’re still going to pick.”

Animal and human studies demonstrate that skin picking and hair pulling primarily affect females. “You will encounter young boys that pick and pull, but it largely affects females, and it tends to start around puberty,” he said. “Picking can have an onset after the age of 30, which is quite uncommon.”

From a cognitive standpoint, pathological skin pickers demonstrate impaired inhibitory control, impaired stop signal reaction time, increased rates of negative urgency (a tendency to act impulsively in response to negative emotions), and increased rates of positive urgency (a tendency to act impulsively in response to exciting or pleasurable emotions).

Trichotillomania

The lifetime prevalence of trichotillomania ranges between 0.6% and 3.9%. The onset is typically from ages 10-13 years, and the mean duration of illness is 22 years.

The DSM-5 criteria for trichotillomania are similar to that of skin-picking disorder, “although we don’t really worry about the substance use issue with people who pull their hair,” Dr. Grant said. “It doesn’t seem to have a correlation.” In addition, sometimes, children “will worsen pulling or picking when they have co-occurring ADHD and they’ve been started on a stimulant, even at a typical dose. For kids who have those issues, we prefer to try nonstimulant options for their ADHD such as bupropion or atomoxetine.”

Individuals with trichotillomania also tend to have low self-esteem and increased social anxiety, he added, and about one-third report low or very low quality of life. “When you notice alopecia, particularly in young girls who often have longer hair, up to 20% will eat their hair,” Dr. Grant said. “We don’t know why. It’s not related to vitamin deficiencies; it’s not a pica type of iron deficiency. There seems to be a shame piece about eating one’s own hair, but it’s important to assess that. Ask about constipation or overflow incontinence because they can get a bezoar, which can rupture” and can be fatal.

Skin-picking disorder and trichotillomania co-occur in up to 20% of cases. “When they do it tends to be a more difficult problem,” he said. These patients often come for mental health care because of depression, and most, he added, say “I don’t think I would be depressed if I wasn’t covered with excoriations or missing most of my hair.”
 

Treatment for both conditions

According to Dr. Grant, the treatment of choice for skin-picking disorder and trichotillomania is a specific psychotherapy known as “habit reversal therapy,” which involves helping the patient gain better self-control. The drawback is that it’s difficult to find someone trained in habit reversal therapy, “who know anything about skin picking and hair pulling,” he said. “That has been a huge challenge in the field.”

In his experience, the medical treatment of choice for skin-picking disorder and trichotillomania is N-acetylcysteine, an over-the-counter amino acid and antioxidant, which has been shown to be helpful at a dose of 2,400 mg per day. “Patients report to me that some of the excoriations clear up a little quicker as they’re taking it,” Dr. Grant said.

There may also be a role for antipsychotic therapy, he said, “but because of the associated weight gain with most antipsychotics we prefer not to use them.”

The opioid antagonist naltrexone has been shown to be effective in the subset of patients with skin-picking or hair-pulling disorders whose parents have a substance use disorder, Dr. Grant said. “The thought is that there’s something addictive about this behavior in some kids. These kids will look forward to picking and find it rewarding and exciting.”

Dr. Grant reported having no relevant financial disclosures.

High-dose vitamin B6 supplements may reduce feelings of anxiety and depression, new research suggests.

Investigators compared supplementation with a 1-month course of vitamin B6 or B12 to supplementation with placebo in almost 500 adults. Results showed that vitamin B6 supplementation was associated with reductions in self-reported anxiety and a trend toward decreased depressive symptoms.

In addition, the vitamin B6 group showed increased levels of gamma-aminobutyric acid (GABA), as indicated by results on a visual test that was administered at the end of the trial. The test results demonstrated subtle changes in participants’ visual performance. The researchers considered this to be consistent with controlled levels of GABA-related brain activity.

However, “before practicing clinicians would recommend taking high doses of vitamin B6, a full-scale clinical trial would have to be carried out to verify the findings, assess any side effects, and find out which types of patients do or don’t benefit,” study investigator David Field, PhD, associate professor, School of Psychological and Clinical Language Sciences, University of Reading (England), told this news organization.

“My relatively small study can only be considered as an initial proof of concept,” Dr. Field said.

The findings were published online in the Journal of Human Psychopharmacology: Clinical and Experimental.
 

Eat Marmite?

“Recent research has connected mood disorders and some other neuropsychiatric conditions with disturbance in this balance, often in the direction of raised levels of brain activity,” Dr. Field noted.

Vitamin B6 is a coenzyme in the synthesis of GABA, an inhibitory neurotransmitter, from glutamate. Some previous research has suggested that vitamins B6 and B12 have a role in improving mood-related outcomes.

Dr. Field had reviewed a 2017 study of the effects on visual processing of eating Marmite, a type of food spread rich in vitamin B, every day for a few weeks.

“Remarkably, the results of that study suggested that eating Marmite had increased the level of the inhibitory neurotransmitter GABA in the visual part of the brain, damping down the level of neural activity slightly,” he said.

However, Marmite contains other B vitamins and other ingredients that might potentially account for this result, “plus, a lot of people don’t like the taste of Marmite,” Dr. Field noted.

Therefore, he wanted to “find out which individual ingredients were driving the effect, and B6 and B12 were the most plausible candidates.”

He decided to test these vitamins individually and to compare them to placebo. “I added the measures of anxiety and depression that were not in the Marmite study because I reasoned that if GABA levels were altered, this could improve those disorders, because we know that decreased levels of GABA in the brain occur in both of those conditions,” Dr. Field added.

Over the course of 5 years, investigators recruited 478 participants aged 18-58 years (mean age, 23 years; 381 women). Of these, 265 reported having anxiety, and 146 reported having depression.

The study participants were randomly assigned to receive either vitamin B6 (100 mg pyroxidine hydrochloride), vitamin B12 (1,000 mg methylcobalmin), or placebo tablets once daily for a month.

They also completed the Screen for Adult Anxiety Related Disorders (SCAARED) and the Mood and Feelings Questionnaire (MFQ) long version at baseline and following supplementation (“post test”), and they underwent three sensory tests that acted as assays of inhibitory function at post test.

In addition, 307 participants completed the Visual Contrast Sensitivity and Surround Suppression, which “measures the minimum percentage contrast between the lighter and darker regions of a striped pattern that can be detected (called the contrast threshold),” the investigators note.

The contrast threshold was measured with and without a suppressive surround mask that increases the threshold – an effect mediated by GABAergic connections in the visual cortex.

Participants (n = 172) also completed the Binocular Rivalry test and the Tactile Test Battery (n = 180). Both tests are designed to measure responses requiring GABAergic inhibitory activity.
 

‘Subtle changes’

ANOVA analyses revealed a “highly significant” reduction in anxiety at post test (F[1,173] = 10.03; P = .002; np 2 = .055), driven primarily by reduced anxiety in the B6 group (t[88] = 3.51; P < .001; d = .37). The placebo group also showed some reduction in anxiety, but it was not deemed significant, and the overall interaction itself did not reach significance.

A comparison of the B12 group with the group that received placebo revealed a significant reduction in anxiety at post test (F[1,175] = 4.08; P = .045; np 2 = .023), similarly driven by reduced anxiety in the B12 group (t[89] = 1.84; P = .069; d = .19) – but the interaction was not significant.

Among the B6 group, there was a highly significant reduction in scores on the generalized anxiety disorder and social anxiety subscales of the SCAARED, and there was a trend toward reductions on the other subscales. Among the B12 group, there was a significant reduction only on scores on the separation anxiety subscale. No significant changes were found in the placebo group.

The ANOVA test analysis of the B6 and placebo group data showed “no uniform direction of change” in depression at post test. The researchers found a “tendency” for depression scores to decrease between baseline and post test in the B6 group but to increase in the placebo group – an interaction that “approached” significance (F[1,96] = 3.08; P = .083; np 2 = .031), they report.

The ANOVA analysis of the B12 and placebo group data revealed no significant or trending effects, and the t-test comparing baseline and post-test scores in the B12 group was similarly nonsignificant.

B6 supplementation did change visual contrast thresholds, but only when a suppressive surround was present. There were “no clear effects” of B6 supplementation on other outcome measures, including binocular rivalry reversal rate and the tactile test battery, the investigators note.

“We found that supplementation with B6 produced subtle changes in tests of visual processing in a way that suggested an increase in the level of the inhibitory neurotransmitter GABA,” Dr. Field reported.

Vitamin B6 is a “cofactor for a metabolic pathway in the brain that converts the excitatory neurotransmitter glutamate into the inhibitory/calming GABA,” he said.

“By increasing the quantity of the cofactor, we slightly speed up the rate of this metabolic process, and so you end up with a bit more of the GABA neurotransmitter and a bit less glutamate. The net effect of this is to slightly reduce the amount of activity in the brain,” Dr. Field added.
 

Most common nutrient deficiency

Carol Johnston, PhD, professor and associate dean for faculty success, College of Health Solutions, Arizona State University, Phoenix, said vitamin B6 is “the most common nutrient deficiency in the United States;” 16% of men and 32% of women are reportedly B6 deficient.

“Young women on birth control are at higher risk for B6 deficiency due to effects of oral contraceptives on B6 metabolism,” whereas vitamin B12 deficiency is more common in older adults, said Dr. Johnston, who was not involved with the study.

The current study’s population mainly consisted of young women, and the interpretation of the data is “limited” because the researchers did not measure blood status for B6 and B12, Dr. Johnston noted. It is possible the sample was low in B6 and that the supplements “improved cognitive measures.”

Because the population was young – no one was older than 60 years – B12 status was likely “adequate in the sample, and supplementation did not have an impact,” she said.

Overall, Dr. Johnston cautioned that it is important to “alert clinicians and the general public about the concerns of overdosing B6.” For example, supplementation at high amounts can cause potentially irreversible sensory neuropathy, she noted.

“The safe upper limit defined by experts is 100 mg per day – the dosage used in this trial. Daily supplementation should not exceed this level,” Dr. Johnston said.

The vitamin tablets used in the study were supplied by Innopure. The investigators and Dr. Johnston have reported no relevant financial relationships.

Vitamin B6 is a coenzyme in the synthesis of GABA, an inhibitory neurotransmitter, from glutamate. Some previous research has suggested that vitamins B6 and B12 have a role in improving mood-related outcomes.

Dr. Field had reviewed a 2017 study of the effects on visual processing of eating Marmite, a type of food spread rich in vitamin B, every day for a few weeks.

“Remarkably, the results of that study suggested that eating Marmite had increased the level of the inhibitory neurotransmitter GABA in the visual part of the brain, damping down the level of neural activity slightly,” he said.

However, Marmite contains other B vitamins and other ingredients that might potentially account for this result, “plus, a lot of people don’t like the taste of Marmite,” Dr. Field noted.

Therefore, he wanted to “find out which individual ingredients were driving the effect, and B6 and B12 were the most plausible candidates.”

He decided to test these vitamins individually and to compare them to placebo. “I added the measures of anxiety and depression that were not in the Marmite study because I reasoned that if GABA levels were altered, this could improve those disorders, because we know that decreased levels of GABA in the brain occur in both of those conditions,” Dr. Field added.

Over the course of 5 years, investigators recruited 478 participants aged 18-58 years (mean age, 23 years; 381 women). Of these, 265 reported having anxiety, and 146 reported having depression.

The study participants were randomly assigned to receive either vitamin B6 (100 mg pyroxidine hydrochloride), vitamin B12 (1,000 mg methylcobalmin), or placebo tablets once daily for a month.

They also completed the Screen for Adult Anxiety Related Disorders (SCAARED) and the Mood and Feelings Questionnaire (MFQ) long version at baseline and following supplementation (“post test”), and they underwent three sensory tests that acted as assays of inhibitory function at post test.

In addition, 307 participants completed the Visual Contrast Sensitivity and Surround Suppression, which “measures the minimum percentage contrast between the lighter and darker regions of a striped pattern that can be detected (called the contrast threshold),” the investigators note.

The contrast threshold was measured with and without a suppressive surround mask that increases the threshold – an effect mediated by GABAergic connections in the visual cortex.

Participants (n = 172) also completed the Binocular Rivalry test and the Tactile Test Battery (n = 180). Both tests are designed to measure responses requiring GABAergic inhibitory activity.
 

‘Subtle changes’

ANOVA analyses revealed a “highly significant” reduction in anxiety at post test (F[1,173] = 10.03; P = .002; np 2 = .055), driven primarily by reduced anxiety in the B6 group (t[88] = 3.51; P < .001; d = .37). The placebo group also showed some reduction in anxiety, but it was not deemed significant, and the overall interaction itself did not reach significance.

A comparison of the B12 group with the group that received placebo revealed a significant reduction in anxiety at post test (F[1,175] = 4.08; P = .045; np 2 = .023), similarly driven by reduced anxiety in the B12 group (t[89] = 1.84; P = .069; d = .19) – but the interaction was not significant.

Among the B6 group, there was a highly significant reduction in scores on the generalized anxiety disorder and social anxiety subscales of the SCAARED, and there was a trend toward reductions on the other subscales. Among the B12 group, there was a significant reduction only on scores on the separation anxiety subscale. No significant changes were found in the placebo group.

The ANOVA test analysis of the B6 and placebo group data showed “no uniform direction of change” in depression at post test. The researchers found a “tendency” for depression scores to decrease between baseline and post test in the B6 group but to increase in the placebo group – an interaction that “approached” significance (F[1,96] = 3.08; P = .083; np 2 = .031), they report.

The ANOVA analysis of the B12 and placebo group data revealed no significant or trending effects, and the t-test comparing baseline and post-test scores in the B12 group was similarly nonsignificant.

B6 supplementation did change visual contrast thresholds, but only when a suppressive surround was present. There were “no clear effects” of B6 supplementation on other outcome measures, including binocular rivalry reversal rate and the tactile test battery, the investigators note.

“We found that supplementation with B6 produced subtle changes in tests of visual processing in a way that suggested an increase in the level of the inhibitory neurotransmitter GABA,” Dr. Field reported.

Vitamin B6 is a “cofactor for a metabolic pathway in the brain that converts the excitatory neurotransmitter glutamate into the inhibitory/calming GABA,” he said.

“By increasing the quantity of the cofactor, we slightly speed up the rate of this metabolic process, and so you end up with a bit more of the GABA neurotransmitter and a bit less glutamate. The net effect of this is to slightly reduce the amount of activity in the brain,” Dr. Field added.
 

Most common nutrient deficiency

Carol Johnston, PhD, professor and associate dean for faculty success, College of Health Solutions, Arizona State University, Phoenix, said vitamin B6 is “the most common nutrient deficiency in the United States;” 16% of men and 32% of women are reportedly B6 deficient.

“Young women on birth control are at higher risk for B6 deficiency due to effects of oral contraceptives on B6 metabolism,” whereas vitamin B12 deficiency is more common in older adults, said Dr. Johnston, who was not involved with the study.

The current study’s population mainly consisted of young women, and the interpretation of the data is “limited” because the researchers did not measure blood status for B6 and B12, Dr. Johnston noted. It is possible the sample was low in B6 and that the supplements “improved cognitive measures.”

Because the population was young – no one was older than 60 years – B12 status was likely “adequate in the sample, and supplementation did not have an impact,” she said.

Overall, Dr. Johnston cautioned that it is important to “alert clinicians and the general public about the concerns of overdosing B6.” For example, supplementation at high amounts can cause potentially irreversible sensory neuropathy, she noted.

“The safe upper limit defined by experts is 100 mg per day – the dosage used in this trial. Daily supplementation should not exceed this level,” Dr. Johnston said.

The vitamin tablets used in the study were supplied by Innopure. The investigators and Dr. Johnston have reported no relevant financial relationships.

Pharmacogenetic testing, which is used to classify how patients with major depressive disorder (MDD) metabolize medications, reduces adverse drug-gene interactions, new research shows.

In a randomized clinical trial that included almost 2,000 adults with MDD, patients in the pharmacogenomics-guided group were more likely to receive an antidepressant that had no potential drug-gene interaction than the patients who received usual care.

In addition, among the intervention group, the rate of remission over 24 weeks was significantly greater.

“These tests can be helpful in rethinking choices of antidepressants, but clinicians should not expect them to be helpful for every patient,” study investigator David W. Oslin, MD, Corporal Michael J. Crescenz VA Medical Center and professor of psychiatry at Perelman School of Medicine, University of Pennsylvania, Philadelphia, said in an interview.

The findings were published online  in JAMA.

Less trial and error

Pharmacogenomic testing can provide information to inform drug selection or dosing for patients with a genetic variation that alters pharmacokinetics or pharmacodynamics. Such testing may be particularly useful for patients with MDD, as fewer than 40% of these patients achieve clinical remission after an initial treatment with an antidepressant, the investigators note.

“To get to a treatment that works for an individual, it’s not unusual to have to try two or three or four antidepressants,” said Dr. Oslin. “If we could reduce that variance a little bit with a test like this, that would be huge from a public health perspective.”

The study included 676 physicians and 1,944 adults with MDD (mean age, 48 years; 24% women) who were receiving care at 22 Department of Veterans Affairs medical centers. Eligible patients were set to start a new antidepressant monotherapy, and all underwent a pharmacogenomic test using a cheek swab.

Investigators randomly assigned patients to receive test results when available (pharmacogenomic-guided group) or 24 weeks later (usual-care group). For the former group, clinicians were asked to initiate treatment when test results were available, typically within 2-3 days. For the latter group, they were asked to initiate treatment on a day of randomization.

Assessments included the 9-item Patient Health questionnaire (PHQ-9), scores for which range from 0-27 points, with higher scores indicating worse symptoms.

Of the total patient population, 79% completed the 24-week assessment.

Researchers characterized antidepressant medications on the basis of drug-gene interaction categories: no known interactions, moderate interactions, and substantial interactions.

The co-primary outcomes were treatment initiation within 30 days, determined on the basis of drug-gene interaction categories, and remission from depression symptoms, defined as a PHQ-9 score of less than or equal to 5.

Raters who were blinded to clinical care and study randomization assessed outcomes at 4, 8, 12, 18, and 24 weeks.
 

Significant impact?

Results showed that the pharmacogenomic-guided group was more likely to receive an antidepressant that had no potential drug-gene interaction, as opposed to one with a moderate/substantial interaction (odds ratio, 4.32; 95% confidence interval, 3.47-5.39; P < .001).

The usual-care group was more likely to receive a drug with mild potential drug-gene interaction (no/moderate interaction vs. substantial interaction: OR, 2.08; 95% CI, 1.52-2.84; P = .005).

For the intervention group, the estimated rates of receiving an antidepressant with no, moderate, and substantial drug-gene interactions were 59.3%, 30.0%, and 10.7%, respectively. For the usual-care group, the estimates were 25.7%, 54.6%, and 19.7%.

The finding that 1 in 5 patients who received usual care were initially given a medication for which there were significant drug-gene interactions means it is “not a rare event,” said Dr. Oslin. “If we can make an impact on 20% of the people we prescribe to, that’s actually pretty big.”

Rates of remission were greater in the pharmacogenomic-guided group over 24 weeks (OR, 1.28; 95% CI, 1.05-1.57; P = .02; absolute risk difference, 2.8%; 95% CI, 0.6%-5.1%).

The secondary outcomes of response to treatment, defined as at least a 50% decrease in PHQ-9 score, also favored the pharmacogenomic-guided group. This was also the case for the secondary outcome of reduction in symptom severity on the PHQ-9 score.

Some physicians have expressed skepticism about pharmacogenomic testing, but the study provides additional evidence of its usefulness, Dr. Oslin noted.

“While I don’t think testing should be standard of practice, I also don’t think we should put barriers into the testing until we can better understand how to target the testing” to those who will benefit the most, he added.

The tests are available at a commercial cost of about $1,000 – which may not be that expensive if testing has a significant impact on a patient’s life, said Dr. Oslin.
 

Important research, but with several limitations

In an accompanying editorial, Dan V. Iosifescu, MD, associate professor of psychiatry at New York University School of Medicine and director of clinical research at the Nathan Kline Institute for Psychiatric Research, called the study an important addition to the literature on pharmacogenomic testing for patients with MDD.

The study was significantly larger and had broader inclusion criteria and longer follow-up than previous clinical trials and is one of the few investigations not funded by a manufacturer of pharmacogenomic tests, writes Dr. Iosifescu, who was not involved with the research.

However, he notes that an antidepressant was not initiated for 30 days after randomization in 25% of the intervention group and in 31% of the usual-care group, which was “puzzling.” “Because these rates were comparable in the 2 groups, it cannot be explained primarily by the delay of the pharmacogenomic test results in the intervention group,” he writes.

In addition, in the co-primary outcome of symptom remission rate, the difference in clinical improvement in favor of the pharmacogenomic-guided treatment was only “modest” – the gain was of less than 2% in the proportion of patients achieving remission, Dr. Iosifescu adds.

He adds this is “likely not very meaningful clinically despite this difference achieving statistical significance in this large study sample.”

Other potential study limitations he cites include the lack of patient blinding to treatment assignment and the absence of clarity about why rates of MDD response and remission over time were relatively low in both treatment groups.

A possible approach to optimize antidepressant choices could involve integration of pharmacogenomic data into larger predictive models that include clinical and demographic variables, Dr. Iosifescu notes.

“The development of such complex models is challenging, but it is now possible given the recent substantial advances in the proficiency of computational tools,” he writes.

The study was funded by the U.S. Department of Veterans Affairs (VA), Health Services Research and Development Service, and the Mental Illness Research, Education, and Clinical Center at the Corporal Michael J. Crescenz VA Medical Center. Dr. Oslin reports having received grants from the VA Office of Research and Development and Janssen Pharmaceuticals and nonfinancial support from Myriad Genetics during the conduct of the study. Dr. Iosifescu report having received personal fees from Alkermes, Allergan, Axsome, Biogen, the Centers for Psychiatric Excellence, Jazz, Lundbeck, Precision Neuroscience, Sage, and Sunovion and grants from Alkermes, AstraZeneca, Brainsway, Litecure, Neosync, Otsuka, Roche, and Shire.

SAN DIEGO – For the first time, the Alzheimer’s Association has released recommendations for the use of blood-based biomarkers in clinical trials and certain clinical situations. The organization has previously published recommendations for use of amyloid positron emission tomography (PET) and cerebrospinal fluid (CSF) biomarkers for Alzheimer’s disease.

The recommendations were the subject of a presentation at the 2022 Alzheimer’s Association International Conference and were published online in Alzheimer’s & Dementia.

During his presentation, Oskar Hansson, MD, PhD, stressed that the document describes recommendations, not criteria, for use of blood-based biomarkers. He suggested that the recommendations will need to be updated within 9-12 months, and that criteria for blood-based biomarkers use could come within 2 years.

The new recommendations reflect the recent acceleration of progress in the field, according to Wiesje M. van der Flier, PhD, who moderated the session. “It’s just growing so quickly. I think within 5 years the whole field will have transformed. By starting to use them in specialized memory clinics first, but then also local memory clinics, and then finally, I think that they may also transform primary care,” said Dr. van der Flier, who is a professor of neurology at Amsterdam University Medical Center.
 

Guidance for clinical trials and memory clinics

The guidelines were created in part because blood-based biomarkers for Alzheimer’s disease have become increasingly available, and there has been a call from the community for guidance, according to Dr. Hansson. There is also a hazard that widespread adoption could interfere with the field itself, especially if physicians don’t understand how to interpret the results. That’s a particularly acute problem since Alzheimer’s disease pathology can precede symptoms. “It’s important to have some guidance about regulating their use so we don’t get the problem that they are misused and get a bad reputation,” said Dr. Hansson in an interview.

The current recommendations are for use in clinical trials to identify patients likely to have Alzheimer’s disease, as well as in memory clinics, though “we’re still a bit cautious. We still need to confirm it with other biomarkers. The reason for that is we still don’t know how these will perform in the clinical reality. So it’s a bit trying it out. You can start using these blood biomarkers to some degree,” said Dr. Hansson.

However, he offered the caveat that plasma-based biomarkers should only be used while confirming that the blood-based biomarkers agree with CSF tests, ideally more than 90% of the time. “If suddenly only 60% of the plasma biomarkers agree with CSF, you have a problem and you need to stop,” said Dr. Hansson.

The authors recommend that blood-based biomarkers be used in clinical trials to help select patients and identify healthy controls. Dr. Hansson said that there is not enough evidence that blood-based biomarkers have sufficient positive predictive value to be used as the sole criteria for clinical trial admission. However, they could also be used to inform decision-making in adaptive clinical trials.

Specifically, plasma Abeta42/Abeta40 and P-tau assays using established thresholds can be used in clinical studies first-screening step for clinical trials, though they should be confirmed by PET or CSF in those with abnormal blood biomarker levels. The biomarkers could also be used in non–Alzheimer’s disease clinical trials to exclude patients with probable Alzheimer’s disease copathology.

In memory clinics, the authors recommend that BBMs be used only in patients who are symptomatic and, when possible, should be confirmed by PET or CSF.
 

More work to be done

Dr. Hansson noted that 50%-70% of patients with Alzheimer’s disease are misdiagnosed in primary care, showing a clear need for biomarkers that could improve diagnosis. However, he stressed that blood-based biomarkers are not yet ready for use in that setting.

Still, they could eventually become a boon. “The majority of patients now do not get any biomarker support to diagnosis. They do not have access to amyloid PET or [CSF] biomarkers, but when the blood-based biomarkers are good enough, that means that biomarker support for an Alzheimer’s diagnosis [will be] available to many patients … across the globe,” said Dr. van der Flier.

There are numerous research efforts underway to validate blood-based biomarkers in more diverse groups of patients. That’s because the retrospective studies typically used to identify and validate biomarkers tend to recruit carefully selected patients, with clearly defined cases and good CSF characterization, according to Charlotte Teunissen, PhD, who is also a coauthor of the guidelines and professor of neuropsychiatry at Amsterdam University Medical Center. “Now we want to go one step further to go real-life practice, and there are several initiatives,” she said.

SAN DIEGO – For the first time, the Alzheimer’s Association has released recommendations for the use of blood-based biomarkers in clinical trials and certain clinical situations. The organization has previously published recommendations for use of amyloid positron emission tomography (PET) and cerebrospinal fluid (CSF) biomarkers for Alzheimer’s disease.

The recommendations were the subject of a presentation at the 2022 Alzheimer’s Association International Conference and were published online in Alzheimer’s & Dementia.

During his presentation, Oskar Hansson, MD, PhD, stressed that the document describes recommendations, not criteria, for use of blood-based biomarkers. He suggested that the recommendations will need to be updated within 9-12 months, and that criteria for blood-based biomarkers use could come within 2 years.

The new recommendations reflect the recent acceleration of progress in the field, according to Wiesje M. van der Flier, PhD, who moderated the session. “It’s just growing so quickly. I think within 5 years the whole field will have transformed. By starting to use them in specialized memory clinics first, but then also local memory clinics, and then finally, I think that they may also transform primary care,” said Dr. van der Flier, who is a professor of neurology at Amsterdam University Medical Center.
 

Guidance for clinical trials and memory clinics

The guidelines were created in part because blood-based biomarkers for Alzheimer’s disease have become increasingly available, and there has been a call from the community for guidance, according to Dr. Hansson. There is also a hazard that widespread adoption could interfere with the field itself, especially if physicians don’t understand how to interpret the results. That’s a particularly acute problem since Alzheimer’s disease pathology can precede symptoms. “It’s important to have some guidance about regulating their use so we don’t get the problem that they are misused and get a bad reputation,” said Dr. Hansson in an interview.

The current recommendations are for use in clinical trials to identify patients likely to have Alzheimer’s disease, as well as in memory clinics, though “we’re still a bit cautious. We still need to confirm it with other biomarkers. The reason for that is we still don’t know how these will perform in the clinical reality. So it’s a bit trying it out. You can start using these blood biomarkers to some degree,” said Dr. Hansson.

However, he offered the caveat that plasma-based biomarkers should only be used while confirming that the blood-based biomarkers agree with CSF tests, ideally more than 90% of the time. “If suddenly only 60% of the plasma biomarkers agree with CSF, you have a problem and you need to stop,” said Dr. Hansson.

The authors recommend that blood-based biomarkers be used in clinical trials to help select patients and identify healthy controls. Dr. Hansson said that there is not enough evidence that blood-based biomarkers have sufficient positive predictive value to be used as the sole criteria for clinical trial admission. However, they could also be used to inform decision-making in adaptive clinical trials.

Specifically, plasma Abeta42/Abeta40 and P-tau assays using established thresholds can be used in clinical studies first-screening step for clinical trials, though they should be confirmed by PET or CSF in those with abnormal blood biomarker levels. The biomarkers could also be used in non–Alzheimer’s disease clinical trials to exclude patients with probable Alzheimer’s disease copathology.

In memory clinics, the authors recommend that BBMs be used only in patients who are symptomatic and, when possible, should be confirmed by PET or CSF.
 

More work to be done

Dr. Hansson noted that 50%-70% of patients with Alzheimer’s disease are misdiagnosed in primary care, showing a clear need for biomarkers that could improve diagnosis. However, he stressed that blood-based biomarkers are not yet ready for use in that setting.

Still, they could eventually become a boon. “The majority of patients now do not get any biomarker support to diagnosis. They do not have access to amyloid PET or [CSF] biomarkers, but when the blood-based biomarkers are good enough, that means that biomarker support for an Alzheimer’s diagnosis [will be] available to many patients … across the globe,” said Dr. van der Flier.

There are numerous research efforts underway to validate blood-based biomarkers in more diverse groups of patients. That’s because the retrospective studies typically used to identify and validate biomarkers tend to recruit carefully selected patients, with clearly defined cases and good CSF characterization, according to Charlotte Teunissen, PhD, who is also a coauthor of the guidelines and professor of neuropsychiatry at Amsterdam University Medical Center. “Now we want to go one step further to go real-life practice, and there are several initiatives,” she said.

Older adults who have spent time in the intensive care unit have double the risk of developing dementia in later years, compared with older adults who have never stayed in the ICU, new research suggests.

“ICU hospitalization may be an underrecognized risk factor for dementia in older adults,” Bryan D. James, PhD, epidemiologist with Rush Alzheimer’s Disease Center, Chicago, said in an interview.

“Health care providers caring for older patients who have experienced a hospitalization for critical illness should be prepared to assess and monitor their patients’ cognitive status as part of their long-term care plan,” Dr. James added.

The findings were presented at the Alzheimer’s Association International Conference.
 

Hidden risk factor?

ICU hospitalization as a result of critical illness has been linked to subsequent cognitive impairment in older patients. However, how ICU hospitalization relates to the long-term risk of developing Alzheimer’s and other age-related dementias is unknown.

“Given the high rate of ICU hospitalization in older persons, especially during the COVID-19 pandemic, it is critical to explore this relationship, Dr. James said.

The Rush team assessed the impact of an ICU stay on dementia risk in 3,822 older adults (mean age, 77 years) without known dementia at baseline participating in five diverse epidemiologic cohorts.

Participants were checked annually for development of Alzheimer’s and all-type dementia using standardized cognitive assessments.

Over an average of 7.8 years, 1,991 (52%) adults had at least one ICU stay; 1,031 (27%) had an ICU stay before study enrollment; and 961 (25%) had an ICU stay during the study period.

In models adjusted for age, sex, education, and race, ICU hospitalization was associated with 63% higher risk of Alzheimer’s dementia (hazard ratio, 1.63; 95% confidence interval, 1.41-1.88) and 71% higher risk of all-type dementia (HR, 1.71; 95% CI, 1.48-1.97).

In models further adjusted for other health factors such as vascular risk factors and disease, other chronic medical conditions and functional disabilities, the association was even stronger: ICU hospitalization was associated with roughly double the risk of Alzheimer’s dementia (HR 2.10; 95% CI, 1.66-2.65) and all-type dementia (HR, 2.20; 95% CI, 1.75-2.77).

Dr. James said in an interview that it remains unclear why an ICU stay may raise the dementia risk.

“This study was not designed to assess the causes of the higher risk of dementia in persons who had ICU hospitalizations. However, researchers have looked into a number of factors that could account for this increased risk,” he explained.

One is critical illness itself that leads to hospitalization, which could result in damage to the brain; for example, severe COVID-19 has been shown to directly harm the brain, Dr. James said.

He also noted that specific events experienced during ICU stay have been shown to increase risk for cognitive impairment, including infection and severe sepsis, acute dialysis, neurologic dysfunction and delirium, and sedation.
 

Important work

Commenting on the study, Heather Snyder, PhD, vice president of medical & scientific relations at the Alzheimer’s Association, said what’s interesting about the study is that it looks at individuals in the ICU, regardless of the cause.

“The study shows that having some type of health issue that results in some type of ICU stay is associated with an increased risk of declining cognition,” Dr. Snyder said.

“That’s really important,” she said, “especially given the increase in individuals, particularly those 60 and older, who did experience an ICU stay over the last couple of years and understanding how that might impact their long-term risk related to Alzheimer’s and other changes in memory.”

“If an individual has been in the ICU, that should be part of the conversation with their physician or health care provider,” Dr. Snyder advised.

The study was funded by the National Institute on Aging. Dr. James and Dr. Snyder disclosed no relevant financial relationships.

Transgender children, even those as young as 9 or 10 years old, already show increased susceptibility to mental health problems compared with their cisgender peers, new research suggests.

Investigators assessed a sample of more than 7000 children aged 9-10 years in the general population and found those who reported being transgender scored considerably higher on all six subscales of the DSM-5-oriented Child Behavior Checklist (CBCL).

Transgender children had almost sixfold higher odds of suicidality and over twice the odds of depressive and anxiety problems, compared with cisgender children. Moreover, transgender children displayed higher levels of mental health problems compared with previous studies of transgender children recruited from specialist gender clinics.

“Our findings emphasize the vulnerability of transgender children, including those who may not yet have accessed specialist support,” senior author Kenneth C. Pang, MBBS, BMedSc, PhD, associate professor, Murdoch Children’s Research Institute, University of Melbourne, Royal Children’s Hospital, Australia, told this news organization.

“Clinicians providing general health care to transgender children should keep this vulnerability in mind and proactively address any mental health problems that exist,” he said.

The findings were published online as a research letter in JAMA Network Open.
 

Higher levels of support?

“We felt this study was important to conduct because previous studies regarding the mental health of transgender children have been drawn from children receiving specialist gender-related care,” Dr. Pang said.

“Transgender children receiving such care are likely to enjoy higher levels of support than those unable to access such services, and this might create differences in mental health,” he added.

To investigate this issue, the researchers turned to participants (n = 7,169; mean age, 10.3 years) in the Adolescent Brain Cognitive Development (ABCD) study.

“The ABCD study is a longitudinal study of over 11,000 children who were recruited to reflect the sociodemographic variation of the U.S. population,” lead author Douglas H. Russell, MSc, a PhD candidate at the University of Melbourne, told this news organization.

To be included in the current study, children had to understand and respond to the question “Are you transgender?”

The researchers compared mental health outcomes between transgender and cisgender children (n = 58 and n = 7,111, respectively) using the CBCL, which study participants had completed at baseline.
 

Key protective factor

The transgender children recorded higher mean T scores for all six subscales of the CBCL, although all children scored in the references range; and the standardized mean difference was “small.”

Suicidality was measured by summing the two suicide-related items in the parent-report CBCL assessing suicidal ideation and attempts.

“For the CBCL, T scores are calculated for measures that are scored on a continuous scale,” Dr. Pang noted. “Responses to the suicidality questions on the CBCL were assessed in a categorical manner (at risk of suicide vs. not), as previously described by others. So T scores were therefore not able to be calculated.”

When the investigators determined the proportion of cisgender and transgender children who scored in the “borderline” or “clinical” range (T score, 65), they found increased odds of transgender children scoring in that range in all six subscales, as well as suicidality.

The researchers note the results for attention-deficit/hyperactivity disorder and oppositional defiant problems were not statistically significant.

Previous studies that used clinical samples of young transgender children (aged 5 -11 years) reported lower rates of depression and anxiety than what was found in the current study.

“Transgender children in the general population displayed higher levels of mental health problems compared to previous studies of transgender children recruited from specialist gender clinics,” Mr. Russell said.

One reason for that may be children in specialist clinics “are likely to have support from their families (a key protective factor for the mental health of transgender young people); in comparison, many transgender children in the general population lack parental support for their gender,” the investigators wrote.

“Our findings suggest that by 9 to 10 years of age transgender children already show increased susceptibility to mental health problems compared with their cisgender peers, which has important public health implications,” they added.

The researchers noted that whether this susceptibility “is due to stigma, minority stress, discrimination, or gender dysphoria is unclear, but providing appropriate mental health supports to this vulnerable group is paramount.”
 

“Pathologizing and damaging”

Commenting for this news organiztion, Jack L. Turban, MD, incoming assistant professor of child and adolescent psychiatry, University of California, San Francisco, said that “sadly” the findings are “largely in line with past studies that have shown dramatic mental health disparities” for transgender and gender diverse youth.

“The dramatically elevated odds of suicidality warrants particular public health concern,” said Dr. Turban, who was not involved with the study.

He noted these results “come at a time when transgender youth are under legislative attack in many states throughout the country, and the national rhetoric around them has been pathologizing and damaging.”

Dr. Turban said that he worries “if our national discourse around trans youth doesn’t change soon, that these disparities will worsen.”

Mr. Russell and Dr. Pang reported being members of the Australian Professional Association for Trans Health. Dr. Pang is a member of the World Professional Association for Transgender Health and a member of the editorial board of the journal Transgender Health.

To investigate this issue, the researchers turned to participants (n = 7,169; mean age, 10.3 years) in the Adolescent Brain Cognitive Development (ABCD) study.

“The ABCD study is a longitudinal study of over 11,000 children who were recruited to reflect the sociodemographic variation of the U.S. population,” lead author Douglas H. Russell, MSc, a PhD candidate at the University of Melbourne, told this news organization.

To be included in the current study, children had to understand and respond to the question “Are you transgender?”

The researchers compared mental health outcomes between transgender and cisgender children (n = 58 and n = 7,111, respectively) using the CBCL, which study participants had completed at baseline.
 

Key protective factor

The transgender children recorded higher mean T scores for all six subscales of the CBCL, although all children scored in the references range; and the standardized mean difference was “small.”

Suicidality was measured by summing the two suicide-related items in the parent-report CBCL assessing suicidal ideation and attempts.

“For the CBCL, T scores are calculated for measures that are scored on a continuous scale,” Dr. Pang noted. “Responses to the suicidality questions on the CBCL were assessed in a categorical manner (at risk of suicide vs. not), as previously described by others. So T scores were therefore not able to be calculated.”

When the investigators determined the proportion of cisgender and transgender children who scored in the “borderline” or “clinical” range (T score, 65), they found increased odds of transgender children scoring in that range in all six subscales, as well as suicidality.

The researchers note the results for attention-deficit/hyperactivity disorder and oppositional defiant problems were not statistically significant.

Previous studies that used clinical samples of young transgender children (aged 5 -11 years) reported lower rates of depression and anxiety than what was found in the current study.

“Transgender children in the general population displayed higher levels of mental health problems compared to previous studies of transgender children recruited from specialist gender clinics,” Mr. Russell said.

One reason for that may be children in specialist clinics “are likely to have support from their families (a key protective factor for the mental health of transgender young people); in comparison, many transgender children in the general population lack parental support for their gender,” the investigators wrote.

“Our findings suggest that by 9 to 10 years of age transgender children already show increased susceptibility to mental health problems compared with their cisgender peers, which has important public health implications,” they added.

The researchers noted that whether this susceptibility “is due to stigma, minority stress, discrimination, or gender dysphoria is unclear, but providing appropriate mental health supports to this vulnerable group is paramount.”
 

“Pathologizing and damaging”

Commenting for this news organiztion, Jack L. Turban, MD, incoming assistant professor of child and adolescent psychiatry, University of California, San Francisco, said that “sadly” the findings are “largely in line with past studies that have shown dramatic mental health disparities” for transgender and gender diverse youth.

“The dramatically elevated odds of suicidality warrants particular public health concern,” said Dr. Turban, who was not involved with the study.

He noted these results “come at a time when transgender youth are under legislative attack in many states throughout the country, and the national rhetoric around them has been pathologizing and damaging.”

Dr. Turban said that he worries “if our national discourse around trans youth doesn’t change soon, that these disparities will worsen.”

Funding was provided to individual investigators by the Hugh Williamson Foundation, the Royal Children’s Hospital foundation, the National Health and Medical Research Council, and the Australian Government Research Training Program Scholarship. Mr. Russell and Dr. Pang reported being members of the Australian Professional Association for Trans Health. Dr. Pang is a member of the World Professional Association for Transgender Health and a member of the editorial board of the journal Transgender Health. Dr. Turban reported textbook royalties from Springer Nature, being on the scientific advisory board of Panorama Global (UpSwing Fund), and payments as an expert witness for the American Civil Liberties Union, Lambda Legal, and Cooley LLP. He has received a pilot research award from AACAP and pharmaceutical partners (Arbor and Pfizer), a research fellowship from the Sorensen Foundation, and freelance payments from the New York Times, the Washington Post, and the Los Angeles Times.

The Canadian Task Force on Preventive Health Care recommends against the routine screening of all pregnant and postpartum women for depression using a standard questionnaire, according to its new guideline.

The basis for its position is the lack of evidence that such screening “adds value beyond discussions about overall wellbeing, depression, anxiety, and mood that are currently a part of established perinatal clinical care.

“We should not be using a one-size-fits all approach,” lead author Eddy Lang, MD, professor and head of emergency medicine at the Cumming School of Medicine, University of Calgary (Alta.), told this news organization.

Instead, the task force emphasizes regular clinical care, including asking patients about their wellbeing and support systems. The task force categorizes the recommendation as conditional and as having very low-certainty evidence.

The recommendation was published in CMAJ.
 

One randomized study

The task force is an independent panel of clinicians and scientists that makes recommendations on primary and secondary prevention in primary care. A working group of five members of the task force developed this recommendation with scientific support from Public Health Agency of Canada staff.

In its research, the task force found only one study that showed a benefit of routine depression screening in this population. This study was a randomized controlled trial conducted in Hong Kong. Researchers evaluated 462 postpartum women who were randomly assigned to receive screening with the Edinburgh Postnatal Depression Scale (EPDS) or no screening 2 months post partum.

“We found the effect of screening in this study to be very uncertain for the important outcomes of interest,” said Dr. Lang.

“These included parent-child stress, marital stress, and the number of infant hospital admissions. The effects of screening on all of these outcomes were very uncertain, mainly because it was such a small trial,” he said.

The task force also assessed how pregnant and postpartum women feel about being screened. What these women most wanted was a good relationship with a trusted primary care provider who would initiate discussions about their mental health in a caring atmosphere.

“Although they told us they liked the idea of universal screening, they admitted to their family doctors that they actually preferred to be asked about their wellbeing, [to be asked] how things were going at home, and [to have] a discussion about their mental health and wellbeing, rather than a formal screening process. They felt a discussion about depression with a primary health care provider during the pregnancy and postpartum period is critical,” said Dr. Lang.

Thus, the task force recommends “against instrument-based depression screening using a questionnaire with cutoff score to distinguish ‘screen positive’ and ‘screen negative’ administered to all individuals during pregnancy and the postpartum period (up to 1 year after childbirth).”
 

Screening remains common

“There’s a lot of uncertainty in the scientific community about whether it’s a good idea to administer a screening test to all pregnant and postpartum women to determine in a systematic way if they might be suffering from depression,” said Dr. Lang.

The task force recommended against screening for depression among perinatal or postpartum women in 2013, but screening is still performed in many provinces, said Dr. Lang.

Dr. Lang emphasized that the recommendation does not apply to usual care, in which the provider asks questions about and discusses a patient’s mental health and proceeds on the basis of their clinical judgment; nor does it apply to diagnostic pathways in which the clinician suspects that the individual may have depression and tests her accordingly.

“What we are saying in our recommendation is that all clinicians should ask about a patient’s wellbeing, about their mood, their anxiety, and these questions are an important part of the clinical assessment of pregnant and postpartum women. But we’re also saying the usefulness of doing so with a questionnaire and using a cutoff score on the questionnaire to decide who needs further assessment or possibly treatment is unproven by the research,” Dr. Lang said.
 

A growing problem

For Diane Francoeur, MD, CEO of the Society of Obstetricians and Gynecologists of Canada, this is all well and good, but the reality is that such screening is better than nothing.

Quebec is the only Canadian province that conducts universal screening for all pregnant and postpartum women, Dr. Francoeur said in an interview. She was not part of the task force.

“I agree that it should be more than one approach, but the problem is that there is such a shortage of resources. There are many issues that can arise when you follow a woman during her pregnancy,” she said.

Dr. Francoeur said that COVID-19 has been particularly tough on women, including pregnant and postpartum women, who are the most vulnerable.

“Especially during the COVID era, it was astonishing how women were not doing well. Their stress level was so high. We need to have a specific approach dedicated to prenatal mental health, because it’s a problem that is bigger than it used to be,” she said.

Violence against women has increased considerably since the beginning of the COVID-19 pandemic, said Dr. Francoeur. “Many more women have been killed by their partners. We have never seen anything like this before, and I hope we will never see this again,” she said.

“Help was more available a few years ago, but now, it’s really hard if and when you need to have a quick consultation with a specialist and the woman is really depressed. It can take forever. So, it’s okay to screen, but then, what’s next? Who is going to be there to take these women and help them? And we don’t have the answer,” Dr. Francoeur said.

Pregnant and postpartum women who suffer from depression need more than pills, she added. “We reassure them and treat their depression pharmacologically, but it’s also a time to give appropriate support and help them through the pregnancy and get well prepared to receive their newborn, because, as we now know, that first year of life is really important for the child, and the mom needs to be supported.”

Funding for the Canadian Task Force on Preventive Health Care is provided by the Public Health Agency of Canada. Dr. Lang and Dr. Francoeur reported no relevant financial relationships.

Cee Elliot is afraid of pregnancy. The 29-year-old retail manager in Connecticut said she has felt that way since puberty, when she “finally understood” pregnancy and reproduction. Always squeamish around babies and pregnant people, she said, as she learned more about the complications birth can cause, the idea of carrying a child herself became increasingly repulsive.

Later, Ms. Elliot said, she was treated poorly by a partner because of her fears, leading to regular panic attacks. She moved on from that partner, but her fear of pregnancy did not. Along the way, she felt her fears were dismissed by doctors and peers alike.

Tokophobia – a severe fear of childbirth – goes beyond the typical anxieties about birth or pregnancy that women often experience. The condition can intrude on everyday life, crippling social interaction and interrupting regular sleep patterns. Although statistics in the United States don’t exist, as many as 14% of women internationally are thought to have tokophobia.

Although psychiatric treatment focusing on past traumas can help, many women resort to managing the condition themselves. Some seek sterilization, whereas others take multiple forms of contraception simultaneously – combining intrauterine devices and oral birth control, for example, experts said. Some women have sought abortions and some even have attempted suicide rather than face giving birth, according to Leila Frodsham, MbChB, a women’s health expert at King’s College London, who has studied tokophobia.

The International Classification of Diseases added tokophobia to its list of diagnostic codes in 2018. But the Diagnostic and Statistical Manual of Mental Disorders, used by clinicians in the United States, has yet to do the same. Without this designation, some doctors are more inclined to diagnose tokophobia than others, Dr. Frodsham said.

“I think some clinicians struggle to understand how much this condition affects women. There isn’t training in it, and I’d like to see it discussed more,” Dr. Frodsham told this news organization.

Dr. Frodsham said she has seen hundreds of patients seeking help with their fear of pregnancy. Many of these women don’t know that they might have a condition that could benefit from psychiatric treatment.

Tokophobia typically takes two forms: primary, which affects women who have never given birth; and secondary, which stems from a previous traumatic birth experience.

“It’s not the pain of childbirth they are afraid of, but rather their fear comes out of a sense that they lack control over themselves and the situation of being pregnant,” Dr. Frodsham said.

Although the phenomenon has been studied internationally, particularly in Europe, fear of childbirth remains almost entirely unexplored in the United States literature.

One of the only scientific examinations of tokophobia in this country was a 2016 survey of 22 women with the condition by researchers at the University of Michigan, Ann Arbor. Published in the Journal of Obstetric, Gynecology & Neonatal Nursing, the survey found that many of the women expressed concern that their race, gender, or level of income might affect the quality of their care. Some women surveyed said they had experienced traumas directly related to systemic inequalities in the health care system.

Lee Roosevelt, PhD, MPH, CNM, a nurse and midwife and a coauthor of the study, said fear of the health care system, coupled with concern over the loss of bodily autonomy, can foster severe aversion to childbirth. In her experience, she said, clinicians often handle these patients poorly.

“If a woman is making the decision not to have children, we want it to be because she has decided for her, and her body, that it is the right thing,” added Lisa Kane Low, PhD, CNM, professor of obstetrics and gynecology at the University of Michigan, who worked with Dr. Roosevelt on the survey. “She shouldn’t feel the decision is made because she can’t access what she needs or the health care system is unable to provide it.”

Access to midwives, doulas, or therapists trained in trauma counseling can allow women to have a voice in their treatment, Dr. Roosevelt said.

No specific medication exists to treat tokophobia; however, drugs for depression or anxiety sometimes help, Dr. Low said. “Women with tokophobia may not need medication but would benefit from other therapies like desensitization or biobehavioral approaches or combinations of those,” she said.
 

Treating triggers

According to Dr. Frodsham, women with tokophobia often experience guilt and isolation. They may avoid speaking to women who are pregnant or avoid discussing pregnancy and childbirth, afraid that doing so may trigger their fear.

“They can’t see how they can get close to this catastrophic thing they think is going to happen to them,” she said. “Many of them think they will die.”

Many patients avoid thinking about memories of traumatic events so as to not trigger extreme emotional responses.

Dr. Roosevelt said developing ways to assess and treat tokophobia has become more urgent, since the Supreme Court’s recent decision to overturn Roe v. Wade could lead to more instances of women carrying unwanted pregnancies.
 

Seeking community

The internet has become a place where women with tokophobia and less severe fears about pregnancy can share their experiences. On the online bulletin board Reddit, r/Tokphobia and r/childfree contain thousands of queries and personal stories about the condition, as well as requests for advice.

Jillian Kilcoyne, who lives in New York and attends college in Michigan, said: “Pregnancy has always freaked me out. A part of me believes it’s a biological injustice that women have to go through such pain and be ignored by the medical community just to give birth.” Ms. Kilcoyne said she has not sought counseling or help from a clinician.

“I’m not sure I even want it,” she told this news organization. “Some people want to get over their phobia because they want families, and others don’t want children at all. I think that those individuals should have the help they need.”

Claudia, a South Carolina resident who asked to be identified only by her first name owing to concerns about her privacy, said her tokophobia began when she started having sex. It grew worse when she developed health conditions that could be exacerbated by pregnancy. She said she stocks up on contraceptives and periodically takes a pregnancy test to ease her nerves.

“This started for me when I realized that having children wasn’t a requirement for life. I didn’t even know there was a name for what I was feeling,” Claudia said in an interview. “So, letting women know they have options, and then not making them feel guilty, or ashamed, is the most important thing. We shouldn’t try to convince women that motherhood is the only, or the correct, path.”

Ms. Elliot urged clinicians to have compassion: “Treat tokophobic patients – especially a pregnant one seeking an abortion – like someone with a life-threatening parasite. Don’t belittle or dismiss them. We’re already going to lose so many lives because of unwanted pregnancies and birth. Don’t add to the number.”

Cee Elliot is afraid of pregnancy. The 29-year-old retail manager in Connecticut said she has felt that way since puberty, when she “finally understood” pregnancy and reproduction. Always squeamish around babies and pregnant people, she said, as she learned more about the complications birth can cause, the idea of carrying a child herself became increasingly repulsive.

Later, Ms. Elliot said, she was treated poorly by a partner because of her fears, leading to regular panic attacks. She moved on from that partner, but her fear of pregnancy did not. Along the way, she felt her fears were dismissed by doctors and peers alike.

Tokophobia – a severe fear of childbirth – goes beyond the typical anxieties about birth or pregnancy that women often experience. The condition can intrude on everyday life, crippling social interaction and interrupting regular sleep patterns. Although statistics in the United States don’t exist, as many as 14% of women internationally are thought to have tokophobia.

Although psychiatric treatment focusing on past traumas can help, many women resort to managing the condition themselves. Some seek sterilization, whereas others take multiple forms of contraception simultaneously – combining intrauterine devices and oral birth control, for example, experts said. Some women have sought abortions and some even have attempted suicide rather than face giving birth, according to Leila Frodsham, MbChB, a women’s health expert at King’s College London, who has studied tokophobia.

The International Classification of Diseases added tokophobia to its list of diagnostic codes in 2018. But the Diagnostic and Statistical Manual of Mental Disorders, used by clinicians in the United States, has yet to do the same. Without this designation, some doctors are more inclined to diagnose tokophobia than others, Dr. Frodsham said.

“I think some clinicians struggle to understand how much this condition affects women. There isn’t training in it, and I’d like to see it discussed more,” Dr. Frodsham told this news organization.

Dr. Frodsham said she has seen hundreds of patients seeking help with their fear of pregnancy. Many of these women don’t know that they might have a condition that could benefit from psychiatric treatment.

Tokophobia typically takes two forms: primary, which affects women who have never given birth; and secondary, which stems from a previous traumatic birth experience.

“It’s not the pain of childbirth they are afraid of, but rather their fear comes out of a sense that they lack control over themselves and the situation of being pregnant,” Dr. Frodsham said.

Although the phenomenon has been studied internationally, particularly in Europe, fear of childbirth remains almost entirely unexplored in the United States literature.

One of the only scientific examinations of tokophobia in this country was a 2016 survey of 22 women with the condition by researchers at the University of Michigan, Ann Arbor. Published in the Journal of Obstetric, Gynecology & Neonatal Nursing, the survey found that many of the women expressed concern that their race, gender, or level of income might affect the quality of their care. Some women surveyed said they had experienced traumas directly related to systemic inequalities in the health care system.

Lee Roosevelt, PhD, MPH, CNM, a nurse and midwife and a coauthor of the study, said fear of the health care system, coupled with concern over the loss of bodily autonomy, can foster severe aversion to childbirth. In her experience, she said, clinicians often handle these patients poorly.

“If a woman is making the decision not to have children, we want it to be because she has decided for her, and her body, that it is the right thing,” added Lisa Kane Low, PhD, CNM, professor of obstetrics and gynecology at the University of Michigan, who worked with Dr. Roosevelt on the survey. “She shouldn’t feel the decision is made because she can’t access what she needs or the health care system is unable to provide it.”

Access to midwives, doulas, or therapists trained in trauma counseling can allow women to have a voice in their treatment, Dr. Roosevelt said.

No specific medication exists to treat tokophobia; however, drugs for depression or anxiety sometimes help, Dr. Low said. “Women with tokophobia may not need medication but would benefit from other therapies like desensitization or biobehavioral approaches or combinations of those,” she said.
 

Treating triggers

According to Dr. Frodsham, women with tokophobia often experience guilt and isolation. They may avoid speaking to women who are pregnant or avoid discussing pregnancy and childbirth, afraid that doing so may trigger their fear.

“They can’t see how they can get close to this catastrophic thing they think is going to happen to them,” she said. “Many of them think they will die.”

Many patients avoid thinking about memories of traumatic events so as to not trigger extreme emotional responses.

Dr. Roosevelt said developing ways to assess and treat tokophobia has become more urgent, since the Supreme Court’s recent decision to overturn Roe v. Wade could lead to more instances of women carrying unwanted pregnancies.
 

Seeking community

The internet has become a place where women with tokophobia and less severe fears about pregnancy can share their experiences. On the online bulletin board Reddit, r/Tokphobia and r/childfree contain thousands of queries and personal stories about the condition, as well as requests for advice.

Jillian Kilcoyne, who lives in New York and attends college in Michigan, said: “Pregnancy has always freaked me out. A part of me believes it’s a biological injustice that women have to go through such pain and be ignored by the medical community just to give birth.” Ms. Kilcoyne said she has not sought counseling or help from a clinician.

“I’m not sure I even want it,” she told this news organization. “Some people want to get over their phobia because they want families, and others don’t want children at all. I think that those individuals should have the help they need.”

Claudia, a South Carolina resident who asked to be identified only by her first name owing to concerns about her privacy, said her tokophobia began when she started having sex. It grew worse when she developed health conditions that could be exacerbated by pregnancy. She said she stocks up on contraceptives and periodically takes a pregnancy test to ease her nerves.

“This started for me when I realized that having children wasn’t a requirement for life. I didn’t even know there was a name for what I was feeling,” Claudia said in an interview. “So, letting women know they have options, and then not making them feel guilty, or ashamed, is the most important thing. We shouldn’t try to convince women that motherhood is the only, or the correct, path.”

Ms. Elliot urged clinicians to have compassion: “Treat tokophobic patients – especially a pregnant one seeking an abortion – like someone with a life-threatening parasite. Don’t belittle or dismiss them. We’re already going to lose so many lives because of unwanted pregnancies and birth. Don’t add to the number.”

Exercise in a pill? Sign us up

You just got home from a long shift and you know you should go to the gym, but the bed is calling and you just answered. We know sometimes we have to make sacrifices in the name of fitness, but there just aren’t enough hours in the day. Unless our prayers have been answered. There could be a pill that has the benefits of working out without having to work out.

In a study published in Nature, investigators reported that they have identified a molecule made during exercise and used it on mice, which took in less food after being given the pill, which may open doors to understanding how exercise affects hunger.

Gonorrhea and grandparents: A match made in prehistoric heaven

*Editorial note: LOTME takes no responsibility for any unfortunate imagery the reader may have experienced from the above headline.

Old people are the greatest. Back pains, cognitive decline, aches in all the diodes down your left side, there’s nothing quite like your golden years. Notably, however, humans are one of the few animals who experience true old age, as most creatures are adapted to maximize reproductive potential. As such, living past menopause is rare in the animal kingdom.

CDC/John Martin Jr.

This is where the “grandmother hypothesis” comes in: Back in Ye Olde Stone Age, women who lived into old age could provide child care for younger women, because human babies require a lot more time and attention than other animal offspring. But how did humans end up living so long? Enter a group of Californian researchers, who believe they have an answer. It was gonorrhea.

When compared with the chimpanzee genome (as well as with Neanderthals and Denisovans, our closest ancestors), humans have a unique mutated version of the CD33 gene that lacks a sugar-binding site; the standard version uses the sugar-binding site to protect against autoimmune response in the body, but that same site actually suppresses the brain’s ability to clear away damaged brain cells and amyloid, which eventually leads to diseases like dementia. The mutated version allows microglia (brain immune cells) to attack and clear out this unwanted material. People with higher levels of this mutated CD33 variant actually have higher protection against Alzheimer’s.

Interestingly, gonorrhea bacteria are coated in the same sugar that standard CD33 receptors bind to, thus allowing them to bypass the body’s immune system. According to the researchers, the mutated CD33 version likely emerged as a protection against gonorrhea, depriving the bacteria of their “molecular mimicry” abilities. In one of life’s happy accidents, it turned out this mutation also protects against age-related diseases, thus allowing humans with the mutation to live longer. Obviously, this was a good thing, and we ran with it until the modern day. Now we have senior citizens climbing Everest, and all our politicians keep on politicking into their 70s and 80s ... well, everything has its drawbacks.
 

Parents raise a glass to children’s food addiction

There can be something pretty addicting about processed foods. Have you ever eaten just one french fry? Or taken just one cookie? If so, your willpower is incredible. For many of us, it can be a struggle to stop.

A recent study from the University of Michigan, which considered the existence of an eating phenotype, suggests our parents’ habits could be to blame.

By administering a series of questionnaires that inquired about food addiction, alcohol use disorders, cannabis use disorder, nicotine/e-cigarette dependence, and their family tree, investigators found that participants with a “paternal history of problematic alcohol use” had higher risk of food addiction but not obesity.

Apparently about one in five people display a clinically significant addiction to highly processed foods. It was noted that foods like ice cream, pizza, and french fries have high amounts of refined carbs and fats, which could trigger an addictive response.

Lindzey Hoover, a graduate student at the university who was the study’s lead author, noted that living in an environment where these foods are cheap and accessible can be really challenging for those with a family history of addiction. The investigators suggested that public health approaches, like restriction of other substances and marketing to kids, should be put in place for highly processed foods.

Maybe french fries should come with a warning label.
 

A prescription for America’s traffic problems

Nostalgia is a funny thing. Do you ever feel nostalgic about things that really weren’t very pleasant in the first place? Take, for instance, the morning commute. Here in the Washington area, more than 2 years into the COVID era, the traffic is still not what it used to be … and we kind of miss it.

PhotoDisk

Nah, not really. That was just a way to get everyone thinking about driving, because AAA has something of an explanation for the situation out there on the highways and byways of America. It’s drugs. No, not those kinds of drugs. This time it’s prescription drugs that are the problem. Well, part of the problem, anyway.

AAA did a survey last summer and found that nearly 50% of drivers “used one or more potentially impairing medications in the past 30 days. … The proportion of those choosing to drive is higher among those taking multiple medications.” How much higher? More than 63% of those with two or more prescriptions were driving within 2 hours of taking at least one of those meds, as were 71% of those taking three or more.

The 2,657 respondents also were asked about the types of potentially impairing drugs they were taking: 61% of those using antidepressants had been on the road within 2 hours of use at least once in the past 30 days, as had 73% of those taking an amphetamine, AAA said.

So there you have it. That guy in the BMW who’s been tailgating you for the last 3 miles? He may be a jerk, but there’s a good chance he’s a jerk with a prescription … or two … or three.

The term schizophrenia carries an incredible load with it.

It is not just a moniker for a serious mental condition but also a tool to support discrimination, shame, and condemnation, as multiple recent studies and surveys have shown.

The evidence suggests that many of the insensitivities of decades and centuries past, though certainly much improved, can still linger today. And when stigma is attached to a condition or status, it creates additional burdens on the people who are already enduring the challenges of their diagnosis.

There is a growing movement among patients and mental health experts to change the name of this complex condition because of both the added onus it places on patients and the fact that it’s simply clinically inaccurate. Opponents argue that the change will not create the sought-after results but instead, will just usher old negative attitudes into a new world.
 

Why the name change?

Recent research and literature suggest that it is time to change the name schizophrenia to reflect a more accurate description of the condition and to reduce the stigma it carries. The term schizophrenia translates to “split mind,” which is misleading from the start. Mental health experts, people who live with the syndrome, and their advocates believe that changing the term to one that is more closely descriptive of the condition can lead to a more tolerant, understanding public.

In 2021, the Consumer Advisory Board at the Psychosis Research Program of the Massachusetts Mental Health Center Public Psychiatry Division of Beth Israel Deaconess Medical Center created a project to collect feedback from key stakeholders about the possibility of a name change. The survey was given to people with lived experience of mental illness and their family members, clinicians, researchers, government officials, and the general public. The results showed that nearly 75% of the people surveyed were ready to embrace a name change.

Matcheri S. Keshavan, MD, and Raquelle I. Mesholam-Gately, PhD, are two of the 13 authors of this study. In an interview, the researchers explained how the study was handled and what the results mean to them.

“About 5 years ago, we were all talking about this idea of renaming schizophrenia. I began thinking that first of all, it doesn’t accurately describe what the condition is, and there’s a lot of stigma associated with the word. We also discussed that the name ‘schizophrenia’ has been changed in several other Asian countries, and there have been some benefits associated with those changes, including people being more comfortable with seeking out care,” said Dr. Mesholam-Gately, psychologist and assistant professor of psychology in the department of psychiatry at Harvard University, Boston.

“We reviewed the literature that was out there already and then we put together a survey that we could give to a broad sample of stakeholders, including people with lived experiences, to get a sense of how stigmatizing they thought the word schizophrenia was and whether they feel that the name schizophrenia should be changed. Then we listed some alternate names for schizophrenia and asked how people felt about those alternate names,” continued Dr. Mesholam-Gately.

The alternative names that received the most support were “altered perception syndrome,” “psychosis spectrum syndrome,” and “neuro-emotional integration disorder.” Dr. Keshavan, a clinical psychiatrist and academic head of psychiatry at Beth Israel Deaconess, said diagnostic name changes have been adopted before in the field and have led to effective results.

“There are several examples in mental health that have gone through this change. For example, autism has been changed to autism spectrum disorder. Manic depressive [disorder] has been changed to bipolar disorder. Mental retardation has been changed to intellectual disability. And those kinds of changes have led to positive benefits and reducing stigma. People are willing to come in for care. For those reasons, we wanted to get the thinking started.”
 

The burden of stigma

The stigma associated with schizophrenia and mental illness in general is as palpable as it is detrimental. Having a mental illness is one thing, but the stigma of carrying such a label is an additional load that individuals must carry as well. Not only does a person with schizophrenia have to manage their symptoms and treatment, both medical and behavioral, but they also must dodge negative attitudes, misinformation, and discrimination that comes from an uneducated or judgmental public. This can lead to different forms of stigma – like self-stigma and label avoidance.

In a recent blog published by the National Alliance on Mental Illness, Casey Clabough, a person who lives with a diagnosis of schizophrenia, explained that people who have this serious mental illness can suffer from the backlash of the stigma. He explains that people with schizophrenia can misinterpret reality and behave in ways that the general public doesn’t understand or accept. As a result, they are labeled “crazy,” the public grows fearful of them, and they retreat to social isolation.

The stigma surrounding mental illness is perpetuated from several sources. Media and pop culture inaccurately portray schizophrenia as an out-of-control condition that makes someone prone to violence and more likely to commit crimes. In actuality, people living with schizophrenia are at increased risk of becoming victims of violence. One study found that people with schizophrenia are at least 14 times more likely to be victims of a violent crime than to be arrested for one.
 

A history of changes

The term “schizophrenia” is actually the result of a name change from over 100 years ago. The condition was first identified as a mental illness by Emil Kraepelin, MD, a German psychiatrist who studied the pathogenesis of neurologic and psychiatric disorders. In his studies of dementia in young adults, Dr. Kraepelin labeled the symptoms of what we now call schizophrenia as “dementia praecox,” or early dementia.

In 1908, a Swiss professor named Paul Eugen Bleuler, MD, challenged the accuracy of the term “dementia praecox” at a meeting of the German Psychiatric Association in Berlin. During this meeting, Dr. Bleuler argued that the term schizophrenia comes closer to describing the splitting of psychic functioning. Dr. Bleuler explained how schizophrenia has primary and secondary symptoms. The four primary symptoms (the four As) are:

• Abnormal associations
• Autistic behavior and thinking
• Abnormal affect
• Ambivalence

According to Dr. Bleuler, if an individual lacks adaptive capacity and support, these primary symptoms could lead to more pronounced secondary symptoms, such as social withdraw, hallucinations, and delusions.

In later years, more research has been done to gain a greater understanding of the illness. Kurt Schneider, a German psychiatrist, presented a group of select symptoms for diagnosing schizophrenia as First Rank Symptoms (FRS) in 1959. These symptoms may be experienced by people with psychosis.

The problem here is twofold. One, people who have bipolar disorder may also suffer from similar symptoms, which leads to problem number two: misdiagnosis. An examination of a collection of 21 studies on FRS used as a tool for schizophrenia diagnosis showed that FRS misdiagnosed almost 20% of individuals as having schizophrenia when, in fact, they didn’t have the illness.
 

A rose by any other name still smells sweet

There is apprehension about the name change from some mental health experts; not all respondents to the survey felt that a name change would help with stigma. Concerns range from potential confusion among medical professionals to changing the name prematurely before the newest revision of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, to having trouble applying for insurance coverages.

“There is a stigma, and people will have [negative] attitudes towards people with schizophrenia,” said William Carpenter, MD, professor of psychiatry and pharmacology at the University of Maryland School of Medicine, Baltimore. “That is going to occur no matter what kind of name you put to it. But the name itself sounds like you’ve been told you have the worst of all mental illnesses. Or you’re never going to get over this, which may be incorrect. So there’s self-stigma, and it’s based on these kinds of feelings.”

“There are several examples in mental health that have gone through this change. For example, autism has been changed to autism spectrum disorder. Manic depressive [disorder] has been changed to bipolar disorder. Mental retardation has been changed to intellectual disability. And those kinds of changes have led to positive benefits and reducing stigma. People are willing to come in for care. For those reasons, we wanted to get the thinking started.”
 

The burden of stigma

The stigma associated with schizophrenia and mental illness in general is as palpable as it is detrimental. Having a mental illness is one thing, but the stigma of carrying such a label is an additional load that individuals must carry as well. Not only does a person with schizophrenia have to manage their symptoms and treatment, both medical and behavioral, but they also must dodge negative attitudes, misinformation, and discrimination that comes from an uneducated or judgmental public. This can lead to different forms of stigma – like self-stigma and label avoidance.

In a recent blog published by the National Alliance on Mental Illness, Casey Clabough, a person who lives with a diagnosis of schizophrenia, explained that people who have this serious mental illness can suffer from the backlash of the stigma. He explains that people with schizophrenia can misinterpret reality and behave in ways that the general public doesn’t understand or accept. As a result, they are labeled “crazy,” the public grows fearful of them, and they retreat to social isolation.

The stigma surrounding mental illness is perpetuated from several sources. Media and pop culture inaccurately portray schizophrenia as an out-of-control condition that makes someone prone to violence and more likely to commit crimes. In actuality, people living with schizophrenia are at increased risk of becoming victims of violence. One study found that people with schizophrenia are at least 14 times more likely to be victims of a violent crime than to be arrested for one.
 

A history of changes

The term “schizophrenia” is actually the result of a name change from over 100 years ago. The condition was first identified as a mental illness by Emil Kraepelin, MD, a German psychiatrist who studied the pathogenesis of neurologic and psychiatric disorders. In his studies of dementia in young adults, Dr. Kraepelin labeled the symptoms of what we now call schizophrenia as “dementia praecox,” or early dementia.

In 1908, a Swiss professor named Paul Eugen Bleuler, MD, challenged the accuracy of the term “dementia praecox” at a meeting of the German Psychiatric Association in Berlin. During this meeting, Dr. Bleuler argued that the term schizophrenia comes closer to describing the splitting of psychic functioning. Dr. Bleuler explained how schizophrenia has primary and secondary symptoms. The four primary symptoms (the four As) are:

• Abnormal associations
• Autistic behavior and thinking
• Abnormal affect
• Ambivalence

According to Dr. Bleuler, if an individual lacks adaptive capacity and support, these primary symptoms could lead to more pronounced secondary symptoms, such as social withdraw, hallucinations, and delusions.

In later years, more research has been done to gain a greater understanding of the illness. Kurt Schneider, a German psychiatrist, presented a group of select symptoms for diagnosing schizophrenia as First Rank Symptoms (FRS) in 1959. These symptoms may be experienced by people with psychosis.

The problem here is twofold. One, people who have bipolar disorder may also suffer from similar symptoms, which leads to problem number two: misdiagnosis. An examination of a collection of 21 studies on FRS used as a tool for schizophrenia diagnosis showed that FRS misdiagnosed almost 20% of individuals as having schizophrenia when, in fact, they didn’t have the illness.
 

A rose by any other name still smells sweet

There is apprehension about the name change from some mental health experts; not all respondents to the survey felt that a name change would help with stigma. Concerns range from potential confusion among medical professionals to changing the name prematurely before the newest revision of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, to having trouble applying for insurance coverages.

“There is a stigma, and people will have [negative] attitudes towards people with schizophrenia,” said William Carpenter, MD, professor of psychiatry and pharmacology at the University of Maryland School of Medicine, Baltimore. “That is going to occur no matter what kind of name you put to it. But the name itself sounds like you’ve been told you have the worst of all mental illnesses. Or you’re never going to get over this, which may be incorrect. So there’s self-stigma, and it’s based on these kinds of feelings.”

The term schizophrenia carries an incredible load with it.

It is not just a moniker for a serious mental condition but also a tool to support discrimination, shame, and condemnation, as multiple recent studies and surveys have shown.

The evidence suggests that many of the insensitivities of decades and centuries past, though certainly much improved, can still linger today. And when stigma is attached to a condition or status, it creates additional burdens on the people who are already enduring the challenges of their diagnosis.

There is a growing movement among patients and mental health experts to change the name of this complex condition because of both the added onus it places on patients and the fact that it’s simply clinically inaccurate. Opponents argue that the change will not create the sought-after results but instead, will just usher old negative attitudes into a new world.
 

Why the name change?

Recent research and literature suggest that it is time to change the name schizophrenia to reflect a more accurate description of the condition and to reduce the stigma it carries. The term schizophrenia translates to “split mind,” which is misleading from the start. Mental health experts, people who live with the syndrome, and their advocates believe that changing the term to one that is more closely descriptive of the condition can lead to a more tolerant, understanding public.

In 2021, the Consumer Advisory Board at the Psychosis Research Program of the Massachusetts Mental Health Center Public Psychiatry Division of Beth Israel Deaconess Medical Center created a project to collect feedback from key stakeholders about the possibility of a name change. The survey was given to people with lived experience of mental illness and their family members, clinicians, researchers, government officials, and the general public. The results showed that nearly 75% of the people surveyed were ready to embrace a name change.

Matcheri S. Keshavan, MD, and Raquelle I. Mesholam-Gately, PhD, are two of the 13 authors of this study. In an interview, the researchers explained how the study was handled and what the results mean to them.

“About 5 years ago, we were all talking about this idea of renaming schizophrenia. I began thinking that first of all, it doesn’t accurately describe what the condition is, and there’s a lot of stigma associated with the word. We also discussed that the name ‘schizophrenia’ has been changed in several other Asian countries, and there have been some benefits associated with those changes, including people being more comfortable with seeking out care,” said Dr. Mesholam-Gately, psychologist and assistant professor of psychology in the department of psychiatry at Harvard University, Boston.

“We reviewed the literature that was out there already and then we put together a survey that we could give to a broad sample of stakeholders, including people with lived experiences, to get a sense of how stigmatizing they thought the word schizophrenia was and whether they feel that the name schizophrenia should be changed. Then we listed some alternate names for schizophrenia and asked how people felt about those alternate names,” continued Dr. Mesholam-Gately.

The alternative names that received the most support were “altered perception syndrome,” “psychosis spectrum syndrome,” and “neuro-emotional integration disorder.” Dr. Keshavan, a clinical psychiatrist and academic head of psychiatry at Beth Israel Deaconess, said diagnostic name changes have been adopted before in the field and have led to effective results.
