The prevalence of dementia among homeless people is almost twice as high as that in housed populations in Ontario, Canada, according to the results of a new study.

The findings suggested that dementia occurs earlier in homeless individuals, and that these patients could benefit from proactive screening and housing interventions.

“Whether dementia caused the homelessness or homelessness caused the dementia, it’s a bidirectional relationship,” said lead author Richard G. Booth, PhD, RN, adjunct scientist at ICES (formerly Institute for Clinical Evaluative Sciences) and associate professor of nursing at Western University in London, Ontario, Canada.

The study was published in the April issue of The Lancet Public Health.

 

Dementia at Early Ages

The investigators used health administrative data from Ontario to compare the prevalence of dementia among homeless people with that among housed individuals in the general population and those living in low-income neighborhoods.

They included individuals aged 45 years or older on January 1, 2019, who visited hospital-based ambulatory care (such as emergency departments), were hospitalized, or visited a community health center in 2019. The researchers identified people as experiencing homelessness if they had one or more healthcare records with an indication of homelessness or unstable housing. The prevalence of dementia was ascertained as of December 31, 2019.

Included in the population-based, cross-sectional comparative analysis were 12,863 homeless people, 475,544 people in the low-income group, and 2,273,068 people in the general population group.

Dementia prevalence was 68.7 per 1000 individuals among the homeless population, 62.6 per 1000 in the low-income group, and 51.0 per 1000 in the general population group.

After adjustments for age, sex, geographical location of residence (urban vs rural), and health conditions associated with dementia, the prevalence ratio of dementia among homeless people was 1.71, compared with the low-income group, and 1.90, compared with the general population group.

Dementia also was detected in the 45- to 55-year age group among homeless people. This age is much earlier than the age at which doctors start screening their patients for cognitive decline (65 years).

“The study was not designed to define the causality but consider: If you have early-stage dementia and you are not intact enough to do basic functions of life, the likelihood of you becoming homeless is definitely increased, and vice versa. If you are homeless and suffer significant environmental and physical traumas just living on the street, you age much quicker, and you will experience geriatric symptoms such as dementia earlier in your life trajectory,” said Dr. Booth.

“The main takeaway here is that if you don’t have housing, bad things are going to happen in life.”
 

Public Health Problem

In an accompanying editorial, William J. Panenka, MD, associate professor of psychiatry at the University of British Columbia in Vancouver, British Columbia, Canada, and colleagues cited modifiable risk factors for dementia, including lower education, traumatic brain injury, substance use, smoking, mood disorders, and social isolation, many of which are disproportionately prevalent among homeless individuals.

“Ultimately, dementia could contribute to the cycle of homelessness, whereby housing instability increases the risk for brain impairment, and brain impairment makes breaking the cycle of homelessness progressively more challenging,” they wrote.

Dr. Panenka and colleagues also pointed out that the average age of homeless people is increasing. In the United States, it is now approximately 50 years. This fact underscores “the immediacy and gravity of the public health problem. A multifaceted approach that integrates healthcare, housing, and social services is needed to better understand and alleviate the health consequences of homelessness. A concerted effort at all levels is vital to inform future public health efforts and stem the tide of increasing morbidity, compromised function, and early mortality in homelessness,” they concluded.

Stephen Hwang, MD, director of the MAP Centre for Urban Health Solutions at St. Michael’s Hospital and Unity Health in Toronto, said that the study may underestimate the magnitude of the problem of dementia among homeless people.

“The methods used in this research study are very strong because they draw upon data for everyone living in the entire province of Ontario, and this is a very powerful way of looking at this challenging problem. The study probably underestimates the magnitude of the problem because to be diagnosed with dementia, patients have to have contact with healthcare providers that make that diagnosis. Often, people experiencing homelessness don’t have extensive contact with the healthcare system, and so their condition may go undiagnosed,” said Dr. Hwang.

A specialist in internal medicine, Dr. Hwang has provided healthcare for homeless people, and his research focuses on homelessness, housing, and health. He said that the findings from the Canadian study are applicable to the United States.

Forced clearances of homeless people and placing them in encampments, something that has been discussed in Florida, is unlikely to solve the problem, he said.

“The approach that has been shown to be beneficial is to engage with people and offer them housing and services that will allow them to exit homelessness without criminalizing the fact that they’re homeless. There really is no reason to think that this approach of forced clearances is going to help anyone.”

This study was supported by ICES (formerly the Institute for Clinical Evaluative Sciences), which is funded by the Ontario Ministry of Health and Ontario Ministry of Long-Term Care. Dr. Booth and Dr. Hwang reported no relevant financial relationships. Dr. Panenka reported receiving a research grant from the Canadian Institutes of Health Research.

SAN DIEGO — While the concept of zoom dysmorphia is well accepted in today’s clinical practice, diagnostic criteria are lacking, especially in virtual settings, according to George Kroumpouzos, MD, PhD, who, with colleagues, recently proposed a screening tool to help identify patients with zoom dysmorphia.

The term, coined in 2020 by dermatologist Shadi Kourosh, MD, MPH, and colleagues at Harvard Medical School, Boston, refers to an altered or skewed negative perception of one’s body image that results from spending extended amounts of time on video calls. Speaking at the annual meeting of the American Academy of Dermatology, Dr. Kroumpouzos, clinical associate professor of dermatology at Brown University, Providence Rhode Island, explained that most people believe that zoom dysmorphia falls within the spectrum of body dysmorphic disorder (BDD). He described zoom dysmorphia as “a facial dysmorphia triggered or aggravated by frequent virtual meetings. Frequent use of videoconferencing platforms is linked to a distorted perception of facial images, which leads to dysmorphic concerns.”

Dr. Kroumpouzos

Individuals with zoom dysmorphia tend to scrutinize their facial features and fixate on what they think needs to improve, he continued. They experience anxiety about attending video conferences with the camera on and feel pressured to appear perfect before virtual meetings. “They find facial flaws during virtual meetings, and they believe others notice their perceived flaws,” he said. “This all has drastic effects on body dissatisfaction and self-esteem, which leads to a desire to seek cosmetic procedures. It interferes with an individual’s life and can trigger or aggravate body dysmorphic disorder.”

While several tools have been validated in cosmetic settings to screen for BDD, such as the 9-item Body Dysmorphic Disorder Questionnaire–Dermatology questionnaire, the 7-item Body Dysmorphic Disorder Questionnaire–Aesthetic Surgery questionnaire, the Cosmetic Procedure Screening Questionnaire, and the Body Dysmorphic Disorder Symptom Scale, no formal screening tools exist to identify zoom dysmorphia. To complicate matters, “identifying dysmorphic concerns in virtual settings can be challenging,” Dr. Kroumpouzos added. “This makes the recognition of zoom dysmorphia during telehealth visits even more difficult.”

Individuals who may have zoom dysmorphia may fear being misunderstood, judged, or ridiculed because of a perceived flaw in appearance, he said, making establishing rapport and eye contact difficult. “There’s a reticence and silence due to the individual’s avoidant characteristics,” he said. “Patients may become easily distracted or disengaged during telehealth visits in case of technical issues. Psychiatric comorbidities can mask symptoms related to dysmorphic concerns.”

To bridge this gap, Dr. Kroumpouzos and colleagues have proposed a screening tool, a questionnaire related to features of zoom dysmorphia, to facilitate recognition of zoom dysmorphia in virtual settings.

The first component consists of open-ended questions such as “Are you comfortable with being interviewed in a virtual appointment?” and “How do you feel about your appearance during virtual meetings?” Such questions “aim to start the dialogue, to facilitate the discussion with a patient who may be shy or avoidant,” Dr. Kroumpouzos explained.

The second component of the tool consists of questions more specific to screening for zoom dysmorphia, starting with “Are you concerned about facial flaws?” If the patient answers no, they don’t qualify for any others, he said. “But, if they answer yes to that question and yes to at least one more [question], they may have zoom dysmorphia.”

Other questions include, “Do you think that your face is not friendly to the camera?” “Do you hesitate to open the camera?” “Have you tried to hide or camouflage your flaw with your hands, hair, makeup, or clothing?” “Have you sought advice from others to improve your appearance or image?” “Do you often use the filter features of the video conferencing platform?” “Did you consider buying a new camera or equipment that helps improve your image?”

If the clinician deems the patient a candidate for the diagnosis of zoom dysmorphia, the tool recommends asking a BDD-focused question: “In the past month, have you been very concerned that there is something wrong with your physical appearance or the way one or more parts of your body look?” If the patient answers yes, “that individual should be invited to fill out a questionnaire specifically for BDD or come to the office for further evaluation,” Dr. Kroumpouzos said.

In his view, the brevity of the proposed screening tool makes it easy to incorporate into clinical practice, and the “yes or no” questions are practical. “It is crucial to elicit the presence of zoom dysmorphia in its early stage,” he said. “Zoom dysmorphia may trigger an increase in BDD, [so] it is essential to identify the presence of BDD in zoom dysmorphia sufferers and treat it appropriately.”

Dr. Kroumpouzos reported having no relevant financial disclosures.

Images generated by photographic computer software are the first to depict accurate images of facial distortions experienced by patients with prosopometamorphopsia (PMO), a rare visual disorder that is often mistaken for mental illness.

PMO is a rare, often misdiagnosed, visual disorder in which human faces appear distorted in shape, texture, position, or color. Most patients with PMO see these distorted facial features all the time, whether they are looking at a face in person, on a screen, or paper.

For this study, investigators worked with a single patient, a 58-year-old man with a 31-month history of seeing what he describes as “demonic”-looking human faces. Unlike most cases of PMO, the patient reported seeing the distortions only when encountering someone in person but not on a screen or on paper.

This allowed researchers to use editing software to create an image on a computer screen that matched the patient’s distorted view.

“This new information should help healthcare professionals grasp the intensity of facial distortions experienced by people with PMO,” study investigator Brad Duchaine, PhD, professor, Department of Psychological and Brain Sciences, Dartmouth College, Hanover, New Hampshire, told this news organization.

“A substantial number of people we have worked with have been misdiagnosed, often with schizophrenia or some sort of psychotic episode, and some have been put on antipsychotics despite the fact they’ve just had some little tweak in their visual system,” he added.

The report was published online on March 23 in The Lancet.
 

Prevalence Underestimated?

Although fewer than 100 cases of PMO have been reported in the literature, Dr. Duchaine said this is likely an underestimate. Based on a response to a website his team created to recruit affected patients, he said he believes “there are far more cases out there that we realize.”

PMO might be caused by a neurologic event that leads to a lesion in the right temporal lobe, near areas of facial processing, but in many cases, the cause is unclear.

PMO can occur in the context of head trauma, as well as cerebral infarction, epilepsy, migraine, and hallucinogen-persisting perception disorder, researchers noted. The condition can also manifest without detectable structural brain changes.

“We’re hearing from a lot of people through our website who haven’t had, or aren’t aware of having had, a neurologic event that coincided with the onset of face distortions,” Dr. Duchaine noted.

The patient in this study had a significant head injury at age 43 that led to hospitalization. He was exposed to high levels of carbon monoxide about 4 months before his symptoms began, but it’s not clear if the PMO and the incident are related.

He was not prescribed any medications and reported no history of illicit substance use.

The patient also had a history of bipolar affective disorder and posttraumatic stress disorder. His visions of distorted faces were not accompanied by delusional beliefs about the people he encountered, the investigators reported.

Neuropsychological tests were normal, and there were no deficits of visual acuity or color vision. Computer-based face perception tests indicated mild impairment in recognition of facial identity but normal recognition of facial expression.

The patient did not typically see distortions when looking at objects, such as a coffee mug or computer. However, said Dr. Duchaine, “if you get enough text together, the text will start to swirl for him.”
 

Eye-Opening Findings

The patient described the visual facial distortions as “severely stretched features, with deep grooves on the forehead, cheeks, and chin.” Even though these faces were distorted, he was able to recognize the people he saw.

Because the patient reported no distortion when viewing facial images on a screen, researchers asked him to compare what he saw when he looked at the face of a person in the room to a photograph of the same person on a computer screen.

The patient alternated between observing the in-person face, which he perceived as distorted, and the photo on the screen, which he perceived as normal.

Researchers used real-time feedback from the patient and photo-editing software to manipulate the photo on the screen until the photo and the patient’s visual perception of the person in the room matched.

“This is the first time we have actually been able to have a visualization where we are really confident that that’s what someone with PMO is experiencing,” said Dr. Duchaine. “If he were a typical PMO case, he would look at the face in real life and look at the face on the screen and the face on the screen would be distorting as well.”

The researchers discovered that the patient’s distortions are influenced by color; if he looks at faces through a red filter, the distortions are greatly intensified, but if he looks at them through a green filter, the distortions are greatly reduced. He now wears green-filtered glasses in certain situations.

Dr. Duchaine hopes this case will open the eyes of clinicians. “These sorts of visual distortions that your patient is telling you about are probably real, and they’re not a sign of broader mental illness; it’s a problem limited to the visual system,” he said.

The research was funded by the Hitchcock Foundation. The authors reported no relevant conflicts of interest.

PMO is a rare, often misdiagnosed, visual disorder in which human faces appear distorted in shape, texture, position, or color. Most patients with PMO see these distorted facial features all the time, whether they are looking at a face in person, on a screen, or paper.

For this study, investigators worked with a single patient, a 58-year-old man with a 31-month history of seeing what he describes as “demonic”-looking human faces. Unlike most cases of PMO, the patient reported seeing the distortions only when encountering someone in person but not on a screen or on paper.

This allowed researchers to use editing software to create an image on a computer screen that matched the patient’s distorted view.

“This new information should help healthcare professionals grasp the intensity of facial distortions experienced by people with PMO,” study investigator Brad Duchaine, PhD, professor, Department of Psychological and Brain Sciences, Dartmouth College, Hanover, New Hampshire, told this news organization.

“A substantial number of people we have worked with have been misdiagnosed, often with schizophrenia or some sort of psychotic episode, and some have been put on antipsychotics despite the fact they’ve just had some little tweak in their visual system,” he added.

The report was published online on March 23 in The Lancet.
 

Prevalence Underestimated?

Although fewer than 100 cases of PMO have been reported in the literature, Dr. Duchaine said this is likely an underestimate. Based on a response to a website his team created to recruit affected patients, he said he believes “there are far more cases out there that we realize.”

PMO might be caused by a neurologic event that leads to a lesion in the right temporal lobe, near areas of facial processing, but in many cases, the cause is unclear.

PMO can occur in the context of head trauma, as well as cerebral infarction, epilepsy, migraine, and hallucinogen-persisting perception disorder, researchers noted. The condition can also manifest without detectable structural brain changes.

“We’re hearing from a lot of people through our website who haven’t had, or aren’t aware of having had, a neurologic event that coincided with the onset of face distortions,” Dr. Duchaine noted.

The patient in this study had a significant head injury at age 43 that led to hospitalization. He was exposed to high levels of carbon monoxide about 4 months before his symptoms began, but it’s not clear if the PMO and the incident are related.

He was not prescribed any medications and reported no history of illicit substance use.

The patient also had a history of bipolar affective disorder and posttraumatic stress disorder. His visions of distorted faces were not accompanied by delusional beliefs about the people he encountered, the investigators reported.

Neuropsychological tests were normal, and there were no deficits of visual acuity or color vision. Computer-based face perception tests indicated mild impairment in recognition of facial identity but normal recognition of facial expression.

The patient did not typically see distortions when looking at objects, such as a coffee mug or computer. However, said Dr. Duchaine, “if you get enough text together, the text will start to swirl for him.”
 

Eye-Opening Findings

The patient described the visual facial distortions as “severely stretched features, with deep grooves on the forehead, cheeks, and chin.” Even though these faces were distorted, he was able to recognize the people he saw.

Because the patient reported no distortion when viewing facial images on a screen, researchers asked him to compare what he saw when he looked at the face of a person in the room to a photograph of the same person on a computer screen.

The patient alternated between observing the in-person face, which he perceived as distorted, and the photo on the screen, which he perceived as normal.

Researchers used real-time feedback from the patient and photo-editing software to manipulate the photo on the screen until the photo and the patient’s visual perception of the person in the room matched.

“This is the first time we have actually been able to have a visualization where we are really confident that that’s what someone with PMO is experiencing,” said Dr. Duchaine. “If he were a typical PMO case, he would look at the face in real life and look at the face on the screen and the face on the screen would be distorting as well.”

The researchers discovered that the patient’s distortions are influenced by color; if he looks at faces through a red filter, the distortions are greatly intensified, but if he looks at them through a green filter, the distortions are greatly reduced. He now wears green-filtered glasses in certain situations.

Dr. Duchaine hopes this case will open the eyes of clinicians. “These sorts of visual distortions that your patient is telling you about are probably real, and they’re not a sign of broader mental illness; it’s a problem limited to the visual system,” he said.

The research was funded by the Hitchcock Foundation. The authors reported no relevant conflicts of interest.

Premenstrual disorders (PMDs) and perinatal depression (PND) appear to have a bidirectional association, a Swedish national registry-based analysis found.

In women with PND, 2.9% had PMDs before pregnancy vs 0.6% in a matched cohort of unaffected women, according to an international team led by Quian Yang, MD, PhD, of the Institute of Environmental Medicine at the Karolinska Institutet in Stockholm, Sweden. Their study appears in PLoS Medicine.

“Preconception and maternity care providers should be aware of the risk of developing perinatal depression among women with a history of PMDs,” Dr. Yang said in an interview. “Healthcare providers may inform women with perinatal depression about the potential risk of PMDs when menstruation returns after childbirth.” She recommended screening as part of routine perinatal care to identify and treat the condition at an early stage. Counseling and medication may help prevent adverse consequences.

In other findings, the correlation with PMDs held for both prenatal and postnatal depression, regardless of any history of psychiatric disorders and also in full-sister comparisons, the authors noted, with a stronger correlation in the absence of psychiatric disorders (P for interaction <.001).

“Interestingly, we noted a stronger association between PMDs and subsequent PND than the association in the other direction, Dr. Yang said. And although many experience PMD symptom onset in adolescence, symptom worsening has been reported with increasing age and parity. “It is possible that women with milder premenstrual symptoms experienced worse symptoms after pregnancy and are therefore first diagnosed with PMD after pregnancy,” the authors hypothesized.

Both PMDs and PND share depressive symptomatology and onset coinciding with hormonal fluctuations, particularly estrogen and progesterone, suggesting a shared etiology, Dr. Yang explained. “It’s plausible that an abnormal response to natural hormone fluctuations predisposes women to both PMDs and PND. However, the underlying mechanism is complex, and future research is needed to reveal the underlying etiology.”

Affecting a majority of women of reproductive age to some degree, PMDs in certain women can cause significant functional impairment and, when severe, have been linked to increased risks of accidents and suicidal behavior. The psychological symptoms of the more serious form, premenstrual dysphoric disorder, for example, are associated with a 50%-78% lifetime risk for psychiatric disorders, including major depressive, dysthymic, seasonal affective, and generalized anxiety disorders, as well as suicidality.

Mood disorders are common in pregnancy and the postpartum period.

The Swedish Study

In 1.8 million singleton pregnancies in Sweden during 2001-2018, the investigators identified 84,949 women with PND and 849,482 unaffected women and individually matched them 10:1 by age and calendar year. Incident PND and PMDs were identified through clinical diagnoses or prescribed medications, and adjustment was made for such demographics as country of birth, educational level, region of residency, and cohabitation status.

In an initial matched-cohort case-control study with a mean follow-up of 6.9 years, PMDs were associated with a nearly five times higher risk of subsequent PND (odds ratio, 4.76; 95% CI, 4.52-5.01; P <.001).

In another matched cohort with a mean follow-up of 7.0 years, there were 4227 newly diagnosed PMDs in women with PND (incidence rate [IR], 7.6/1000 person-years) and 21,326 among controls (IR, 3.8/1000). Compared with matched controls, women with PND were at almost twice the risk of subsequent PMDs (hazard ratio, 1.81; 95% CI, 1.74-1.88; P <.001).

Commenting on the study but not involved in it, Bernard L. Harlow, PhD, a professor of epidemiology at Boston University School of Public Health in Massachusetts who specializes in epidemiologic studies of female reproductive disorders, said he was not surprised at these findings, which clearly support the need for PMD screening in mothers-to-be. “Anything that is easy to measure and noninvasive that will minimize the risk of postpartum depression should be part of the standard of care during the prenatal period.” As to safety: If treatment is indicated, he added, “studies have shown that the risk to the mother and child is much greater if the mother’s mood disorder is not controlled than any risk to the baby due to depression treatment.” But though PMDs may be predictive of PND, there are still barriers to actual PND care. A 2023 analysis reported that 65% of mothers-to-be who screened positive for metal health comorbidities were not referred for treatment.

Dr. Yang and colleagues acknowledged that their findings may not be generalizable to mild forms of these disorders since the data were based on clinical diagnoses and prescriptions.

The study was supported by the Chinese Scholarship Council, the Swedish Research Council for Health, Working Life and Welfare, the Karolinska Institutet, and the Icelandic Research Fund. The authors and Dr. Harlow had no relevant competing interests to disclose.

One in three Black men in rural America experienced suicidal or death ideation (SDI) in the past week, new research showed.

A developmental model used in the study showed a direct association between experiences pertaining to threat, deprivation, and racial discrimination during childhood and suicide risk in adulthood, suggesting that a broad range of adverse experiences in early life may affect SDI risk among Black men.

“During the past 20-30 years, young Black men have evinced increasing levels of suicidal behavior and related cognitions,” lead author Steven Kogan, PhD, professor of family and consumer sciences at the University of Georgia, Athens, Georgia, and colleagues wrote.

“By controlling for depressive symptoms in assessing increases in SDI over time, our study’s design directly informed the extent to which social adversities affect SDI independent of other depressive problems,” they added.

The findings were published online in Cultural Diversity and Ethnic Minority Psychology.
 

Second Leading Cause of Death

Suicide is the second leading cause of death for Black Americans ages 15-24, according to the Centers for Disease Control and Prevention. The outlook is worse for Black men, whose death rate from suicide is about four times greater than for Black women.

Previous research suggests Black men are disproportionately exposed to social adversity, including poverty and discrimination, which may increase the risk for SDI. In addition, racial discrimination has been shown to increase the risks for depression, anxiety, and psychological distress among Black youth and adults.

But little research exists to better understand how these negative experiences affect vulnerability to SDI. The new study tested a model linking adversity during childhood and emerging exposure to racial discrimination to increases in suicidal thoughts.

Researchers analyzed data from 504 participants in the African American Men’s Project, which included a series of surveys completed by young men in rural Georgia at three different time points over a period of about 3 years.

Composite scores for childhood threat and deprivation were developed using the Adverse Childhood Experiences Scale and Childhood Trauma Questionnaire. Everyday discrimination was measured on the Schedule of Racist Events response scale.

To assess their experience with childhood threats, the men in the study, who were about 21 years old on average when they enrolled, were asked if they experienced a series of adverse childhood experiences and deprivation through age 16. Questions explored issues such as directly experiencing physical violence or witnessing abuse in the home and whether the men felt loved and “important or special” as children.

The investigators also asked the men about their experiences of racial discrimination, the quality of their relationships, their belief that aggression is a means of gaining respect, and their cynicism regarding romantic relationships.
 

Targeted Prevention

Overall, 33.6% of participants reported SDI in the previous week. A history of childhood threats and deprivation was associated with an increased likelihood of SDI (P < .001).

Researchers also found that a history of racial discrimination was significantly associated with the development of negative relational schemas, which are characterized by beliefs that other people are untrustworthy, uncaring, and/or hostile. Negative schemas were in turn associated with an increased risk for suicidal thoughts (P = .03).

“Clinical and preventive interventions for suicidality should target the influence of racism and adverse experiences and the negative relational schemas they induce,” the investigators noted.

“Policy efforts designed to dismantle systemic racism are critically needed. Interventions that address SDI, including programming designed to support Black men through their experiences with racial discrimination and processing of childhood experiences of adversity, may help young Black men resist the psychological impacts of racism, expand their positive support networks, and decrease their risk of SDI,” they added.

The study authors reported no funding sources or relevant financial relationships.

What if a walk in a green environment could reshape brains, recalibrate sense of time, and stave off mental health conditions? If the research trends are true, you might soon find yourself writing prescriptions of 20 minutes of nature per day.

Evidence for the health benefits of exposure to green spaces, like parks, open spaces, gardens, outdoor gyms, and woodland trails, has been mostly interventional and observational, but that has not stopped global recognition that these exposures are important. 

In the wake of the pandemic, the British government allocated more than £5 million to pandemic recovery efforts that specifically involved green spaces. Since then, it has committed even more funding toward an expansive social prescribing program that connects patients to “link workers” who determine personal care needs and facilitate community and volunteer-based interventions. These can include group walking and volunteering to help out in community gardens or conservation efforts. Similar green programs can be found in Japan, where shinrin-yoku (forest bathing) was recently adopted as a national health strategy, and in the United States and Canada.

“Disconnection from nature is a major part of the health problems that we have on this planet,” said William Bird, a UK-based general practitioner, green prescriber, and CEO of Intelligent Health, which is geared toward building healthy, active, and connected communities. Dr. Bird received the prestigious Member of the Order of the British Empire (MBE) in 2010 for services related to physical activity and health. 

“Our brains are designed to connect to nature ... and we haven’t lost that instinct,” he explained. “Once we are with birdsong and water flowing and greenery, cortisol levels drop, our central vagus nerve improves, our fight and flight [response] disappears, and we start to be more receptive to other people.” 
 

Shifting Time Perception and Health

Ricardo A. Correia, PhD, a biologist and researcher at the University of Helsinki in Finland, said he believed that the mechanism for at least some of these outcomes might be differences in how time is perceived. In a perspective that appeared in March in People and Nature, Dr. Correia explored how the “services” that nature provides shift time perceptions and, in turn, regulate overall well-being. 

“I reached the realization that there was some evidence for the shift in some of the dimensions that we use to make sense of time in urban vs natural environments,” he told this news organization. 

Dr. Correia explained that human time perception facilitates understanding cause and effect, so we can act in a way that allows us to survive. 

“Time perception in humans is really complex and multifaceted,” he said. “The way that we make sense of time is not directly attached to any sensory organ, but rather goes through a range of cognitive, emotional, and bodily processes, all of which vary from person to person.” 

Dr. Correia pointed to evidence showing that time perception is shorter in urban environments and longer in natural ones. This, in turn, influences attention and attention restoration. “When we live in cities, we are exposed to similar sorts of demanding environments, increased time pressures, less time for oneself and for recreational purposes,” he said. “Ever-mounting pressure on daily demands plus processes we use to make sense of time, especially attention, means that we pay a cognitive toll.”

Dr. Correia posits that it might be possible to recalibrate time perception, but only by breaking the cycle of exposure. 

“If we are always exposed to fast-paced lifestyles, we become attuned to them and get caught up in an endless loop.” This cycle can be broken, Dr. Correia explained, by increasing exposure to natural environments. This leads to positive emotions, a sense of being in the present, and a heightened sense of mindfulness, all of which help mitigate the physical and mental health outcomes commonly associated with time scarcity. 
 

Brain-Mental Health Benefits

To date, there is quite a bit of research exploring the impacts of exposure to nature on the brain. For example, data have shown that adolescents raised exclusively in rural environments have a larger hippocampus and better spatial processing than children exclusively raised in cities. Other research demonstrated that spending just an hour in the forest led to a decline in amygdala activity in adults, whereas it remained stable after walking in an urban setting, underscoring the salutogenic effects on brain regions related to stress. There is also evidence from a 10-year longitudinal study of more than 2 million Welsh adults that highlights the value of proximity to green or blue (eg, lakes and rivers) spaces and common mental health conditions, with every additional 360 meters to the nearest green or blue space associated with 10% greater odds of anxiety and depression.

Dr. Bird said there has been a massive sea change in attitudes among general practitioners, who have come around to embracing the concept of nature as medicine. This shift among peers, who teased him in the 1990s about his green walking and conservation prescriptions, portends a bandwagon of epic proportions that could benefit patients. He said that he was especially hopeful that green prescriptions will become mainstream in certain conditions, especially those like depression and anxiety that are resistant to medication.

But Dr. Bird cautions that primary care professionals need to be mindful. “Patients need to know that it’s real science, otherwise they’ll think that they’re being pawned off or dismissed,” he said. “I try to put real evidence behind it and explain that there’s no contraindication. The main thing is to start where patients are, what they’re feeling, and what they need. Some people just don’t like nature,” he said.

Logan is a 62-year-old woman who has reached the pinnacle of professional success. She started a $50 million consumer products company and, after selling it, managed to develop another successful brand. She is healthy and happily married, with four adult children. And yet, despite all her achievements and stable family life, Logan was always bothered by her inability to lose weight. 

Despite peddling in beauty, she felt perpetually overweight and, frankly, unattractive. She has no family history of obesity, drinks minimal alcohol, and follows an (allegedly) healthy diet. Logan had tried “everything” to lose weight — human growth hormone injections (not prescribed by me), Ozempic-like medications, Belviq, etc. — all to no avail. 

Here’s the catch: After she finished with her busy days of meetings and spreadsheets, Logan sat down to read through countless emails and rewarded herself with all her favorite foods. Without realizing it, she often doubled her daily caloric intake in one sitting. She wasn’t hungry in these moments, rather just a little worn out and perhaps a little careless. She then proceeded to email her doctor (me) to report on this endless cycle of unwanted behavior. 

In January 2024, a novel study from Turkey examined the relationship between hedonic eating, self-condemnation, and self-esteem. Surprising to no one, the study determined that higher hedonic hunger scores were associated with lower self-esteem and an increased propensity to self-stigmatize.

Oprah could have handily predicted this conclusion. Many years ago, she described food as a fake friend: Perhaps you’ve had a long and difficult day. While you’re busy eating your feelings, the heaping plate of pasta feels like your best buddy in the world. However, the moment the plate is empty, you realize that you feel worse than before. Not only do you have to unbutton your new jeans, but you also realize that you have just lost your ability to self-regulate. 

While the positive association between hedonic eating and low self-esteem may seem self-evident, the solution is less obvious. Mindfulness is one possible approach to this issue. Mindfulness has been described as “paying attention in a particular way: on purpose, in the present moment, and nonjudgmentally” and has existed for thousands of years. Mindful eating, in particular, involves paying close attention to our food choices and how they affect our emotions, and typically includes some combination of:

• Slowing down eating/chewing thoroughly
• Eliminating distractions such as TV, computers, and phones — perhaps even eating in silence
• Eating only until physically satiated
• Distinguishing between true hunger and cravings
• Noticing the texture, flavors, and smell of food
• Paying attention to the effect of food on your mood
• Appreciating food

In our society, where processed food is so readily available and stress is so ubiquitous, eating can become a hedonic and fast-paced activity. Our brains don’t have time to process our bodies’ signals of fullness and, as a result, we often ingest many more calories than we need for a healthy lifestyle. 

If mindless eating is part of the problem, mindful eating is part of the solution. Indeed, a meta-review of 10 scientific studies showed that mindful eating is as effective as conventional weight loss programs in regard to body mass index and waist circumference. On the basis of these studies — as well as some good old-fashioned common sense — intuitive eating is an important component of sustainable weight reduction. 

Eventually, I convinced Logan to meet up with the psychologist in our group who specializes in emotional eating. Through weekly cognitive-behavioral therapy sessions, Logan was able to understand the impetus behind her self-defeating behavior and has finally been able to reverse some of her lifelong habits. Once she started practicing mindful eating, I was able to introduce Ozempic, and now Logan is happily shedding several pounds a week.

Cognitive assessments administered via a smartphone app are a reliable and valid way to detect frontotemporal dementia (FTD) in high-risk individuals, new research showed.

Cognitive tests administered remotely on the phone “showed similar findings as our gold standard in-clinic cognitive tests and brain imaging,” said study investigator Adam M. Staffaroni, PhD, with the Memory and Aging Center, University of California San Francisco.

“We also provided evidence that these assessments may be useful for detecting early symptoms of the disease at a level that is on par, or perhaps slightly better, than our gold standard in-person tests,” Dr. Staffaroni said.

The study was published online in JAMA Network Open.
 

Tough to Diagnose

Although relatively rare, FTD is the top cause of dementia in patients younger than 60 years. Patients are usually diagnosed relatively late in the disease because they are young and because their symptoms may be mistaken for psychiatric disorders.

In addition, behavioral and motor symptoms of FTD can make it hard for families to get to an academic center for in-clinic assessments, making remote assessments a huge need.

Dr. Staffaroni and colleagues with the ALLFTD Consortium partnered with software company Datacubed Health to develop the ALLFTD-mApp, which includes cognitive, motor, and speech tasks.

They assessed the reliability and validity of the app, against standard in-clinic assessments, in 350 individuals (mean age, 54 years; 58% women; mean education level, 16.5 years).

Among the 329 individuals with data on disease stage, 195 (59%) were asymptomatic or had preclinical FTD, 66 (20%) had prodromal FTD, and 68 (21%) had symptomatic FTD with a range of clinical syndromes.

The smartphone app showed “moderate to excellent” reliability within a single administration (ie, internally consistent) and across repeated assessments (ie, test-retest reliability), the researchers reported.

Validity was supported by association of smartphones tests with disease severity, criterion-standard neuropsychological tests, and brain volume, they noted.
 

Of Great Interest

They also reported that a composite of brief smartphone tests accurately distinguished dementia from cognitively unimpaired participants, screening out participants without symptoms, and detected prodromal FTD with greater sensitivity than the Montreal Cognitive Assessment.

“This tool is currently being used in several research studies. The remote aspect of this technology is important because it could allow researchers to collect data more frequently, which may give them a more accurate picture of the disease. Furthermore, researchers can be more inclusive in their study designs and include participants who otherwise might have difficulty traveling to academic centers for standard in-person visits,” said Dr. Staffaroni.

“Because the app appears sensitive to early stages of the disease, it could be also used as a screening tool, possibly alongside other remote data collection, to help identify participants that might be appropriate for a clinical trial. At this point, these technologies are not ready for clinical use and require additional research studies to understand their clinical utility,” he cautioned.

Commenting on the study, Walter Kukull, PhD, director of the National Alzheimer’s Coordinating Center at the University of Washington in Seattle, noted that “remote direct and indirect testing/telemetry are of great interest to the field and are being examined carefully in comparison to in-person means both for validity and possibly earlier recognition.”

This research was supported by grants from the National Institutes of Health, the Association for Frontotemporal Degeneration, the Bluefield Project to Cure FTD, the Rainwater Charitable Foundation, and the Larry L. Hillblom Foundation. Dr. Staffaroni reported being a coinventor of four ALLFTD mobile application tasks (not analyzed in the current study); receiving licensing fees from Datacubed Health and research support from the National Institute on Aging of the NIH, Bluefield Project to Cure FTD, the Alzheimer’s Association, the Larry L. Hillblom Foundation, and the Rainwater Charitable Foundation; and consulting for Alector Inc., Eli Lilly and Company Prevail Therapeutics, Passage Bio Inc, and Takeda Pharmaceuticals. Dr. Kukull participated in the ALLFTD Consortium.

Commenting on the study, Walter Kukull, PhD, director of the National Alzheimer’s Coordinating Center at the University of Washington in Seattle, noted that “remote direct and indirect testing/telemetry are of great interest to the field and are being examined carefully in comparison to in-person means both for validity and possibly earlier recognition.”

Cognitive assessments administered via a smartphone app are a reliable and valid way to detect frontotemporal dementia (FTD) in high-risk individuals, new research showed.

Cognitive tests administered remotely on the phone “showed similar findings as our gold standard in-clinic cognitive tests and brain imaging,” said study investigator Adam M. Staffaroni, PhD, with the Memory and Aging Center, University of California San Francisco.

“We also provided evidence that these assessments may be useful for detecting early symptoms of the disease at a level that is on par, or perhaps slightly better, than our gold standard in-person tests,” Dr. Staffaroni said.

The study was published online in JAMA Network Open.
 

Tough to Diagnose

Although relatively rare, FTD is the top cause of dementia in patients younger than 60 years. Patients are usually diagnosed relatively late in the disease because they are young and because their symptoms may be mistaken for psychiatric disorders.

In addition, behavioral and motor symptoms of FTD can make it hard for families to get to an academic center for in-clinic assessments, making remote assessments a huge need.

Dr. Staffaroni and colleagues with the ALLFTD Consortium partnered with software company Datacubed Health to develop the ALLFTD-mApp, which includes cognitive, motor, and speech tasks.

They assessed the reliability and validity of the app, against standard in-clinic assessments, in 350 individuals (mean age, 54 years; 58% women; mean education level, 16.5 years).

Among the 329 individuals with data on disease stage, 195 (59%) were asymptomatic or had preclinical FTD, 66 (20%) had prodromal FTD, and 68 (21%) had symptomatic FTD with a range of clinical syndromes.

The smartphone app showed “moderate to excellent” reliability within a single administration (ie, internally consistent) and across repeated assessments (ie, test-retest reliability), the researchers reported.

Validity was supported by association of smartphones tests with disease severity, criterion-standard neuropsychological tests, and brain volume, they noted.
 

Of Great Interest

They also reported that a composite of brief smartphone tests accurately distinguished dementia from cognitively unimpaired participants, screening out participants without symptoms, and detected prodromal FTD with greater sensitivity than the Montreal Cognitive Assessment.

“This tool is currently being used in several research studies. The remote aspect of this technology is important because it could allow researchers to collect data more frequently, which may give them a more accurate picture of the disease. Furthermore, researchers can be more inclusive in their study designs and include participants who otherwise might have difficulty traveling to academic centers for standard in-person visits,” said Dr. Staffaroni.

“Because the app appears sensitive to early stages of the disease, it could be also used as a screening tool, possibly alongside other remote data collection, to help identify participants that might be appropriate for a clinical trial. At this point, these technologies are not ready for clinical use and require additional research studies to understand their clinical utility,” he cautioned.

Dogs can detect stress-related compounds in the breath of people experiencing early signs of trauma, including those with posttraumatic stress disorder (PTSD), a new proof-of-concept study suggested.

The research provides evidence that some service dogs with PTSD can be trained to detect episodes of pending distress through a person’s breath and perhaps prompt the individual to use coping skills to manage the episode.

“Ours is the first study to demonstrate that at least some dogs can detect putative stress-related volatile organic compounds in human breath that are associated with PTSD symptoms,” study author Laura Kiiroja, PhD candidate, department of psychology and neuroscience, faculty of science, Dalhousie University, Halifax, Nova Scotia, Canada, told this news organization.

The study was published online on March 28, 2024, in Frontiers of Allergy.

Heightened Sense of Smell

The lifetime prevalence of PTSD is about 8% in the general population, but data show it can reach 23% in veterans. In addition, many more trauma-exposed individuals experience subthreshold symptoms.

Research is investigating the application of dogs’ sense of smell — which is up to 100,000 times more sensitive than humans’ — to detect cancers, viruses, parasites, hypoglycemia, and seizures in humans.

There is also some evidence that dogs can detect putative stress-related volatile organic compounds (VOCs) such as isoprene and monoterpenes from the human body through urine, sweat, and breath, with the greatest success achieved with breath.

The new study included 26 mostly civilian “donors” (mean age, 31 years; 18 females) who had experienced various types of trauma but had no severe mental illness. More than 50% met the criteria for PTSD.

Participants were recruited from a study examining neurocognitive mechanisms underlying the potential links between trauma and cannabis use. However, participants in the dog study abstained from using cannabis for at least 12 hours prior to the study experiments.

Breath Donors

Breath samples were collected via disposable medical-grade face masks at baseline and during ensuing experiments. In total, 40 breath sample sets were collected.

Two female companion dogs — Ivy, a red golden retriever, and Callie, a German shepherd/Belgian Malinois mix — were trained to identify target odors from the samples.

The animals were tested to determine whether they were able to discriminate between breath samples collected from these same “breath donors” during a relatively relaxed state and during induced stress testing which is known as the alternative forced choice discrimination test.

The dogs’ ability to discern trauma cues from breath samples of various individuals was tested by presenting one sample (baseline or trauma cue) at a time. The researchers used signal detection theory to evaluate the sensitivity and specificity of dogs in detecting human stress VOCs.

Investigators found the dogs had about a 90% accuracy rate across all sample sets in the discrimination experiment and 74% and 81% accuracy for Ivy and Callie, respectively, in the detection experiment.

“Our study contributed to the evidence showing that not only are dogs able to detect some physical health conditions in humans but also that some mental health conditions alter the released VOCs in a way that is detectable by dogs,” Ms. Kiiroja said.

Emotion Detectors

At baseline and during each cue exposure, donors reported their affect using the Positive and Negative Affect Schedule. Ivy’s performance correlated with the donors’ self-reported anxiety, and Callie’s performance correlated with the donors’ self-reported shame.

Based on these correlations, the researchers speculate Ivy detected VOCs that likely originated from the sympathetic-adrenomedullary axis, which involves adrenaline and noradrenaline.

VOCs detected by Callie likely originated in the hypothalamus-pituitary-adrenal axis, which involves cortisol and corticosterone. These two endocrine subsystems play a major role in reestablishing homeostasis in response to a stressor.

The results suggest some service dogs could alert to upcoming intrusion and hyperarousal symptoms even before physical signs manifest and before the person is even aware of the situation, said Ms. Kiiroja.

“This would enable earlier distraction and reminders to use skills learned in psychotherapy; this would have a better likelihood of increasing the efficacy of these skills and preventing further escalation of the arousal,” she said.

Most breath samples likely included both early and late stress VOCs, as the breath donors wore the trauma mask for a relatively long time, the authors noted. Future studies should test dogs’ olfactory acuity on samples collected minutes after the trauma cue, they added.

Another limitation is that all donors were regular cannabis users, so the results may not generalize to others. However, the fact the dogs demonstrated their detection ability even with cannabis users makes the proof-of-concept “more stringent,” Ms. Kiiroja said.

The goal of the study was to see if some dogs are capable of detecting stress VOCs from people with trauma histories in response to trauma cues, so the small number of dogs in the study isn’t a limitation, the authors noted.

‘Wonderful Work’

Commenting on the findings, Elspeth Ritchie, MD, chair of psychiatry, MedStar Washington Hospital Center, Washington, described the research as “wonderful work.” Dr. Ritchie, who was not a part of this study, has also studied PTSD supports dogs.

The study is yet another illustration of the “amazing things dogs can do ... not just for veterans but for people with mental illness.” They can be a source of comfort and help people manage their anxiety.

Training PTSD service dogs can be expensive, with some well-accredited organizations charging about $50,000 for an animal, Dr. Ritchie said. Training a dog to detect VOCs could also be costly, she added.

Although such research has increased in recent years, it’s unclear how it would be applied in practice. Identifying funding for this sort of study and designing trials would also be challenging, Dr. Ritchie added.

“The idea is good, but when you try to operationalize it, it gets tricky,” she said.

The fact that all donors in the study used cannabis is a confounding factor and raises the question of what else might confound the results, Dr. Ritchie added.

Dr. Ritchie emphasized that although ideally veterans would learn to recognize the onset of stress symptoms themselves, a dog could serve as a valuable companion in this process. “That’s precisely why this research should progress,” she said.

The authors and Dr. Ritchie reported no relevant disclosures.

This case is a little out of the ordinary, but we would love to find out how readers would handle it.

Diana is a 51-year-old woman with a history of depression, obesity, hypertension, type 2 diabetes, and coronary artery disease. She has come in for a routine visit for her chronic illnesses. She seems very distant and has a flat affect during the initial interview. When you ask about any recent stressful events, she begins crying and explains that her daughter was just deported, leaving behind a child and boyfriend.

Their country of origin suffers from chronic instability and violence. Diana’s father was murdered there, and Diana was the victim of sexual assault. “I escaped when I was 18, and I tried to never look back. Until now.” Diana is very worried about her daughter’s return to that country. “I don’t want her to have to endure what I have endured.”

You spend some time discussing the patient’s mental health burden and identify a counselor and online resources that might help. You wonder if Diana’s adverse childhood experiences (ACEs) might have contributed to some of her physical illnesses.

ACEs and Adult Health

The effects of trauma run long and deep. ACEs have been associated with higher risks for multiple chronic conditions, even among adults aged 60 years or older. Therefore, clinicians should consider a patient’s history of ACEs as part of their evaluation of risk for chronic illness.

One of the most pronounced and straightforward links is that between ACEs and depression. In the Southern Community Cohort Study of more than 38,200 US adults, the highest odds ratio between ACEs and chronic disease was for depression. Persons who reported more than three ACEs had about a twofold increase in the risk for depression compared with persons without ACEs. There was a monotonic increase in the risk for depression and other chronic illnesses as the burden of ACEs increased.

In another study from the United Kingdom, each additional ACE was associated with a significant 11% increase in the risk for incident diabetes during adulthood. Researchers found that both depression symptoms and cardiometabolic dysfunction mediated the effects of ACEs in promoting higher rates of diabetes.

Depression and diabetes are significant risk factors for coronary artery disease, so it is not surprising that ACEs are also associated with a higher risk for coronary events. A review by Godoy and colleagues described how ACEs promote neuroendocrine, autonomic, and inflammatory dysfunction, which in turn leads to higher rates of traditional cardiovascular risk factors such as diabetes and obesity. Ultimately, the presence of four or more ACEs is associated with more than a twofold higher risk for cardiovascular disease compared with no ACEs.

Many of the pathologic processes that promote cardiovascular disease also increase the risk for dementia. Could the reach of ACEs span decades to promote a higher risk for dementia among older adults? A study by Yuan and colleagues of 7222 Chinese adults suggests that the answer is yes. This study divided the cohort into persons with a history of no ACEs, household dysfunction during childhood, or mistreatment during childhood. Child mistreatment was associated with higher rates of diabetes, depression, and cardiovascular disease, as well as an odds ratio of 1.37 (95% CI, 1.12 to 1.68) for cognitive impairment.

The magnitude of the effects ACEs can have on well-being is reinforced by epidemiologic data surrounding ACEs. According to the US Centers for Disease Control and Prevention (CDC), 64% of US adults report at least one ACE and 17% experienced at least four ACEs. Risk factors for ACEs include being female, American Indian or Alaska Native, or unemployed.

How do we reduce the impact of ACEs? Prevention is key. The CDC estimates that nearly 2 million cases of adult heart disease and more than 20 million cases of adult depression could be avoided if ACEs were eliminated.

But what is the best means to pragmatically reduce ACEs in our current practice models? How do we discover a history of ACEs in patients, and what are the best practices in managing persons with a positive history? We will cover these critical subjects in a future article, but for now, please provide your own comments and pearls regarding the prevention and management of ACEs.

Could the reach of ACEs span decades to promote a higher risk for dementia among older adults? A study by Yuan and colleagues of 7222 Chinese adults suggests that the answer is yes. This study divided the cohort into persons with a history of no ACEs, household dysfunction during childhood, or mistreatment during childhood. Child mistreatment was associated with higher rates of diabetes, depression, and cardiovascular disease, as well as an odds ratio of 1.37 (95% CI, 1.12 to 1.68) for cognitive impairment.

The magnitude of the effects ACEs can have on well-being is reinforced by epidemiologic data surrounding ACEs. According to the US Centers for Disease Control and Prevention (CDC), 64% of US adults report at least one ACE and 17% experienced at least four ACEs. Risk factors for ACEs include being female, American Indian or Alaska Native, or unemployed.

How do we reduce the impact of ACEs? Prevention is key. The CDC estimates that nearly 2 million cases of adult heart disease and more than 20 million cases of adult depression could be avoided if ACEs were eliminated.

But what is the best means to pragmatically reduce ACEs in our current practice models? How do we discover a history of ACEs in patients, and what are the best practices in managing persons with a positive history? We will cover these critical subjects in a future article, but for now, please provide your own comments and pearls regarding the prevention and management of ACEs.
