Peak seasons, times for suicidal thoughts, attempts identified
In addition, the results from Harvard University’s Project Implicit Health also show that people are most likely to make an attempt at suicide between 4 and 6 a.m.
“No research has demonstrated a peak in suicidal ideation in winter until our paper,” study investigator Brian O’Shea, PhD, assistant professor of social psychology at the University of Nottingham, England, told this news organization.
“Most people incorrectly assume that suicide behaviours peak in winter and are surprised, as I was, when learning about this phenomenon, that suicide actually peaks in spring/early summer,” he added.
However, at least one expert cautioned that the database, which comprises mostly responses from younger women, doesn’t capture responses from those who are most likely to attempt suicide: older men with substance abuse.
The findings were published online in Translational Psychiatry.
New insight into suicide risk
Previous studies examining the seasonality of suicides and suicide attempts have reported a peak in spring and early summer, but there has been very little information about why this may be, the investigators noted.
Dr. O’Shea and his colleague from the University of Amsterdam, René Freichel, mined one of the databases from Project Implicit Health, which contains self-report measures on suicidal ideation, self-harm, and past suicide attempts, as well as respondents’ implicit biases on these topics.
The analysis included data from 10,000 respondents living in the United States, United Kingdom, and Canada provided between April 2012 and November 2018.
The sample was predominantly young and female, with 38% (3,247) of the sample reporting that they had made at least one suicide attempt.
The researchers found a peak in negative mood and desire to die occurring in December, especially among those who reported attempting suicide (P ≤ .001)
Suicidal ideation peaked approximately 3-4 months before the annual seasonal crest of suicide attempts in early spring and summer.
“Affected individuals may become severely depressed and experience a lack of energy throughout the winter months. Essentially, this period may put them below a threshold of severe suicide risk as the high level of suicidal ideation coincides with a low level of energy,” said Dr. O’Shea.
When the days get longer, brighter, and warmer, these changes likely improve an individuals’ mood, he explained. “Hence, the most at-risk individuals become slightly less depressed and may gain more energy to contemplate and plan their method to attempt suicide,” Dr. O’Shea noted.
A major limitation of the study is that all responses included in analysis were based on self-report.
To confirm the findings, future research should include ecological momentary assessment, which involves using a large community sample to question participants about suicidal intent at various time points, along with real-time monitoring of vital signs, said Dr. O’Shea.
Ideally, the investigators noted, the study’s findings will inform clinician assessments of patients who are at risk for suicide.
A research gap?
Commenting on the findings, Justin Shuster, MD, MPH, assistant professor of psychiatry at the University of Pittsburgh and medical director of two psychiatric units at Western Psychiatric Hospital, noted that the database used in the study did not include responses from those who were most likely to attempt or commit suicide: older men with a history of substance abuse, who require social supports, and who have a family history of suicide.
Though Dr. Shuster agreed with Dr. O’Shea about the possibility that spring brought energy to a desire to take one’s life, he had another theory.
“When people are depressed in the winter, they expect to feel better with the advent of the warmer weather in spring. When they don’t feel better, they may think to themselves, ‘If I’m going to feel like this forever, I may as well follow through with these plans,’ ” he said.
As for the early morning attempts, he noted that 4-6 a.m. is often when people are alone, and there are fewer distractions.
“The other thing I see a great deal of clinically is intoxication,” said Dr. Shuster. “Either intoxication with substances or alcohol, or the fact that intoxication is waning at those early morning hours, and people are becoming desperate as they face a new day,” he said.
The study was funded by a German Academic Exchange Service Scholarship and an EU Horizon 2020 Fellowship. Dr. O’Shea reports being an unpaid member of Project Implicit’s scientific advisory board and is on the executive committee of Project Implicit Health.

Will a mindfulness approach to depression boost recovery rates, reduce costs?
Self-help mindfulness-based cognitive therapy (MBCT-SH) produced better outcomes for participants with depression and was more cost-effective than CBT-SH.
Practitioner-supported self-help therapy regimens are growing in popularity as a way to expand access to mental health services and to address the shortage of mental health professionals.
Generally, mindfulness-based cognitive therapy aims to increase awareness of the depression maintenance cycle while fostering a nonjudgmental attitude toward present-moment experiences, the investigators note.
In contrast, CBT aims to challenge negative and unrealistic thought patterns that may perpetuate depression, replacing them with more realistic and objective thoughts.
“Practitioner-supported MBCT-SH should be routinely offered as an intervention for mild to moderate depression alongside practitioner-supported CBT-SH,” the investigators note.
The study was published online in JAMA Psychiatry.
Better recovery rates?
CBT-SH traditionally had been associated with high attrition rates, and alternative forms of self-help therapy are becoming increasingly necessary to fill this treatment gap, the researchers note. To compare the efficacy and cost-effectiveness of both treatment types, the researchers recruited 410 participants with mild to moderate depression at 10 sites in the United Kingdom. Participants were randomly assigned to receive either MBCT-SH or CBT-SH between November 2017 and January 2020. A total of 204 participants received MBCT-SH, and 206 received CBT-SH.
All participants were given specific self-help workbooks, depending on the study group to which they were assigned. Those who received MBCT-SH used “The Mindful Way Workbook: An 8-Week Program to Free Yourself From Depression and Emotional Distress,” while those who received CBT-SH used “Overcoming Depression and Low Mood: A Five Areas Approach, 3rd Edition.”
Investigators asked all participants to guide themselves through six 30- to 45-minute sessions, using the information in the workbooks. Trained psychological well-being practitioners supported participants as they moved through the workbooks during the six sessions.
Participants were assessed at baseline with the Patient Health Questionnaire–9 (PHQ-9) and the Clinical Interview Schedule–Revised at 16 weeks and 24 weeks.
At 16 weeks post randomization, results showed that practitioner-supported MBCT-SH led to significantly greater reductions in depression symptom severity, compared with practitioner-supported CBT-SH (mean [standard deviation] PHQ-9 score, 7.2 [4.8] points vs. 8.6 [5.5] points; between-group difference, –1.5 points; 95% confidence interval, –2.6 to –0.4; P = .009).
Results also showed that on average, the CBT-SH intervention cost $631 more per participant than the MBCT-SH intervention over the 42-week follow-up.
The investigators explain that “a substantial proportion of this additional cost was accounted for by additional face-to-face individual psychological therapy accessed by CBT-SH participants outside of the study intervention.
“In conclusion, this study found that a novel intervention, practitioner-supported MBCT-SH, was clinically superior in targeting depressive symptom severity at postintervention and cost-effective, compared with the criterion standard of practitioner-supported CBT-SH for adults experiencing mild to moderate depression,” the investigators write.
“If study findings are translated into routine practice, this would see many more people recovering from depression while costing health services less money,” they add.
Clinically meaningful?
Commenting on the study for this article, Lauren Bylsma, PhD, professor of psychiatry and psychology at the University of Pittsburgh, cast doubt on the ability of such a short trial to determine meaningful change.
She said that the extra costs incurred by participants in the CBT-SH arm of the study are likely, since it is “difficult to do CBT alone – you need an objective person to guide you as you practice.”
Dr. Bylsma noted that ultimately, more real-world studies of therapy are needed, given the great need for mental health.
The study was funded by the National Institute for Health and Care Research. The original article contains a full list of the authors’ relevant financial relationships.

Rheumatoid arthritis linked to increased Parkinson’s risk
Claims data in 55,000 patients with RA and 273,000 age- and sex-matched controls show that those with RA were 1.74 times more likely than controls to be diagnosed with PD.
“If patients with rheumatoid arthritis begin exhibiting motor symptoms such as muscle rigidity, tremors, or slowed movement, it is imperative that they be evaluated by a qualified neurologist to rule out the possibility of developing Parkinson’s disease,” study investigator Hyungjin Kim, MD, PhD, told this news organization.
Dr. Kim is an associate professor in the department of medical humanities at Sungkyunkwan University School of Medicine in Seoul, South Korea.
The findings were published online in JAMA Neurology.
Conflicting findings
The investigators note that a number of studies have examined the link between RA and PD, with conflicting results – one even showing a 35% reduced risk for PD for individuals with RA. A more recent population-based study in Taiwan showed a 37% higher rate of PD in patients with rheumatic disease.
However, previous studies did not control for important variables such as body mass index or diabetes.
For the current study, the investigators analyzed claims on about 55,000 patients diagnosed with RA between 2010 and 2017, with follow-up until 2019, and compared the outcomes of this group vs. those of 273,000 controls.
The mean age of claimants was 58 years, and 75% were female.
Results showed that those diagnosed with seropositive RA were about twice as likely as controls to be diagnosed with PD. Those with seronegative RA were 1.2 times as likely as controls to be diagnosed with PD.
Dr. Kim noted that although the pathogenic link between RA and PD remains elusive, inflammation probably plays an important role. “Inflammatory cytokines such as tumor necrosis factor alpha and interleukin-6, which are increased in RA patients, can induce microglial activation, leading to neuroinflammation,” he stated.
“These inflammatory cytokines are known to be associated with the dysfunction and degeneration of nigral dopaminergic neurons, which are important in the pathogenesis of PD,” he added.
The investigators noted that patients with RA may have been subject to more frequent health care services than controls and so were more likely to obtain a PD diagnosis.
Another possibility was that because patients with health check-ups were included in the analysis, the findings may have been biased toward those who were older and who had a higher income.
Dr. Kim noted that additional research is required to clarify the pathogenic connection between RA and PD.
“Moreover, additional studies are necessary to explore the potential influence of novel therapeutic treatments for RA on Parkinson’s disease susceptibility in patients with RA,” he said.
Commenting on the findings for this news organization, David Sulzer, PhD, professor of psychiatry, neurology, and pharmacology at Columbia University in New York, said that the study adds to the growing body of evidence showing there is an autoimmune component to PD.
Dr. Sulzer pointed to data in several papers he published with others to this effect, including one showing higher rates of PD in people with inflammatory bowel disease.
The study had no specific funding. The study investigators and Dr. Sulzer report no relevant disclosures.

New tool accurately predicts suicide risk in serious mental illness
The 17-question Oxford Mental Illness and Suicide Tool (OxMIS) assessment is designed to predict 12-month suicide risk in people with schizophrenia spectrum disorders and bipolar disorder based on risk factors such as familial traits, antisocial traits, and information about self-harm.
“We have demonstrated the clinical utility of OxMIS in two separate studies and countries. As with any clinical risk prediction tool, it will not improve outcomes unless coupled with effective interventions,” lead investigator Amir Sariaslan, PhD, a senior research fellow in psychiatric epidemiology at the University of Oxford, England, told this news organization.
The findings were published online in Translational Psychiatry.
Twice validated
Dr. Sariaslan and his team originally developed and validated the OxMIS in a cohort of 75,000 people with SMI in Sweden. Recognizing the lack of externally validated prognostic models in the mental health field, the team wanted to validate the instrument in a new, population-based sample in Finland.
The investigators accessed information about patient diagnosis and treatment from the Finnish Care Register for Health Care, which contains de-identified information for all individuals between ages 15 and 65 years diagnosed with an SMI between Jan. 1, 1996, and Dec. 31, 2017.
They included 137,000 patients with somatic symptom disorder or bipolar disorder for a total of more than 5 million episodes of inpatient or outpatient treatment. Investigators linked the cohort to the Causes of Death Register to identify those who had died by suicide within 12 months of an index treatment episode, which investigators randomly selected for each person.
The investigators found that 1,475 individuals in the sample died by suicide within 1 year of their index episode (1.1%).
Each patient was assigned a clinical suicide risk score based on their clinical information, familial traits, prescription information, and comorbid conditions. Using OxMIS, the investigators found that the instrument accurately predicted suicide with an area under the curve of 0.70.
In other words, in 70% of the instances where the investigators randomly selected two people from the sample, one of whom died by suicide and the other of whom did not, the individual who died by suicide had a higher OxMIS risk score.
The investigators note the model overestimated the risk for patients who were at extremely high risk for suicide (those with a predicted suicide risk of > 5%). “In our complementary sensitivity analysis, we observed improved calibration in these patients when we assigned them a suicide risk prediction of no more than 5%,” they write.
Dr. Sariaslan said that the findings highlight the importance of safety planning interventions. “It is also essential to remember that OxMIS is not intended to replace clinical decision-making, but rather to support it,” he said.
As to whether the tool could be used in other populations, such as in the United States, Dr. Sariaslan said, “there is no good evidence that the contribution of risk factors to suicide in this population is different in the U.S. than in northern Europe, so there is no a priori reason to have to do multiple external validations before it can be used for research or clinical purposes.”
One size does not fit all
Commenting on the study, Ronald Kessler, PhD, McNeil Family Professor, department of health care policy at Harvard Medical School, Boston, said that he’d be “surprised” if OxMIS was adopted in the United States because there is already an existing tool that is “slightly more accurate,” which he helped develop.
“In addition, when we start thinking about uses for such scales, it becomes clear that different scales should be used for different segments of the population, depending on intervention options,” Dr. Kessler said.
“So, for example, a different scale would probably be optimal in deciding how to manage psychiatric inpatients in the transition back to the community after hospital discharge than [it would be], say, in deciding how to respond to suicidality among patients presenting at an emergency department. No one scale will fit for all the scenarios in which prediction is desired,” he added.
The study was funded by the Academy of Finland. Dr. Kessler receives funding from the National Institute of Mental Health, Department of Defense, and Veterans Administration to develop suicide prediction models. Dr. Sariaslan has no disclosures to report.

High-dose vitamin D and MS relapse: New phase 3 data
, results from a randomized control trial show. However, at least one expert believes the study’s exclusion criteria may have been too broad.
The investigation of vitamin D to prevent relapse of MS is based on older observational studies of people who already had higher blood levels of vitamin D and were less likely to develop MS, said study investigator Ellen Mowry, MD, Richard T. and Frances W. Johnson professor of neurology, Johns Hopkins University, Baltimore.
Later research where participants were given vitamin D as a therapeutic option for MS “were disappointing as the vitamin D had minimal effect,” she said.
“While we were excited by early data suggesting that vitamin D may have an important impact on MS, it’s essential to follow those linkage studies with the gold standard clinical evidence, which we have here,” Dr. Mowry added.
The findings were published online in eClinicalMedicine.
No difference in relapse risk
The multisite, phase 3 Vitamin D to Ameliorate MS (VIDAMS) clinical trial included 172 participants aged 18-50 years with RRMS from 16 neurology clinics between 2012 and 2019.
Inclusion criteria were having one or more clinical episodes of MS in the past year and at least one brain lesion on MRI in the past year or having two or more clinical episodes in the past year. Eligible participants also had to have a score of 4 or less on the Kurtzke Expanded Disability Status Scale.
A total of 83 participants were randomly assigned to receive low-dose vitamin D3 (600 IU/day) and 89 to receive high-dose vitamin D3 (5,000 IU/day). Each participant took the vitamin tablet with glatiramer acetate, a synthetic protein that simulates myelin.
Participants were assessed every 12 weeks to measure serum 25(OH)D levels and every 24 weeks for a number of movement and coordination tests, as well as two 3T clinical brain MRIs to check for lesions.
By the trial’s end at 96 weeks, the researchers found no differences in relapse risk between the high- and low-dose groups (P = .57). In addition, there were no differences in MRI outcomes between the two groups.
Dr. Mowry said that more than a few people have asked her if she is disappointed by the results of the VIDAMS trial. “I tell them that no, I’m not – that we are scientists and clinicians, and it is our job to understand what they can do to fight their disease. And if the answer is not vitamin D, that’s OK – we have many other ideas.”
These include helping patients minimize cardiometabolic comorbidities, such as heart disease and blood pressure, she said.
Exclusion criteria too broad?
Commenting on the findings, Alberto Ascherio, MD, professor of epidemiology and nutrition at Harvard School of Public Health, Boston, said a key principle of recommending vitamin supplements is that they are, generally speaking, only beneficial for individuals with vitamin deficiencies.
He noted that “patients with vitamin D deficiency (25(OH)D < 15 ng/mL, which corresponds to 37.5 nmol/L) were excluded from this study. Most importantly, the baseline mean 25(OH)D levels were about 30 ng/mL (75 nmol/L), which is considered a sufficient level (the IOM considers 20 ng/mL = 50 nmol/L as an adequate level),” with the level further increasing during the trial due to the supplementation.
“It would be a serious mistake to conclude from this trial (or any of the previous trials) that vitamin D supplementation is not important in MS patients,” Dr. Ascherio said.
He added that many individuals with MS have serum vitamin D levels below 20 ng/mL (50 nmol/L) and that this was the median serum value in studies among individuals with MS in Europe.
“These patients would almost certainly benefit from moderate doses of vitamin D supplements or judicious UV light exposure. Most likely even patients with sufficient but suboptimal 25(OH)D levels (between 20 and 30 ng/mL, or 50 and 75 nmol/L) would benefit from an increase,” he said.
The study was funded by the National Multiple Sclerosis Society, Teva Neuroscience, and the National Institute of Health. Dr. Mowry reported grant support from the National MS Society, Biogen, Genentech, and Teva Neuroscience; honoraria from UpToDate; and consulting fees from BeCare Link.

Erratic sleep, lack of activity tied to worsening schizophrenia symptoms
The findings also showed that people with schizophrenia spectrum disorders (SSDs) who lived in residential facilities experienced rigid routines, which correlated with a higher degree of negative symptoms.
The rigid routines were problematic for the patients living in residential settings, lead investigator Fabio Ferrarelli, MD, PhD, told this news organization. Dr. Ferrarelli is an associate professor of psychiatry at the University of Pittsburgh.
“Engaging in different activities at different times in activities associated with motivation and social interaction – this helps to ameliorate difficult-to-treat negative symptoms,” he said.
The findings were published online in Molecular Psychiatry.
Need to increase activity levels
While there is no shortage of research on sleep disturbances among people with schizophrenia, research focusing specifically on rest-activity rhythm disturbances and their relationships to symptoms of schizophrenia has been limited by small sample sizes or the lack of a control group, the investigators note.
To address this research gap, the investigators recruited 230 patients with SSD from participating residential facilities and communities throughout Italy. The participants included 108 healthy control participants, 54 community-dwelling patients with SSD who were receiving outpatient services, and 68 patients with SSD who were living in residential facilities.
All participants wore an actigraph for 7 consecutive days so that investigators could monitor sleep-wake patterns.
Compared with healthy control participants, both SSD groups had more total sleep time and spent more time resting or being passive (P < .001). In contrast, healthy control participants were much more active.
Part of the explanation for this may be that most of the control participants had jobs or attended school. In addition, the investigators note that many medications used to treat SSD can be highly sedating, causing some patients to sleep up to 15 hours per day.
Among residential participants with SSD, there was a higher level of inter-daily stability and higher daily rest-activity-rest fragmentation than occurred among healthy control participants or community-dwelling patients with SSD (P < .001). There was also a higher level of negative symptoms among residential participants with SSD than among the community-dwelling group with SSD.
When the findings were taken together, Dr. Ferrarelli and his team interpreted them to mean that inter-daily stability could reflect premature aging or neurodegenerative processes in patients with more severe forms of schizophrenia.
Another explanation could be that the rigid routine of the residential facility was making negative symptoms worse, Dr. Ferrarelli said. It is important to add variety into the mix – getting people to engage in different activities at different times of day would likely help residential SSD patients overcome negative symptoms of the disorder.
Although participants were recruited in Italy, Dr. Ferrarelli said he believes the findings are generalizable.
Bidirectional relationship?
Commenting on the findings, Matcheri Keshavan, MD, professor of psychiatry at Harvard Medical School in Boston, said the results are consistent with “well-known clinical observations that SSD patients tend to spend more time in bed and have more dysregulated sleep.
“Negative symptoms are also common, especially in residential patients. However, it is difficult to determine causality, as we do not know whether excessive sleepiness and decreased physical activity cause negative symptoms, or vice versa, or whether this is a bidirectional relationship,” Dr. Keshavan said.
He emphasized that physical exercise is known to increase sleep quality for people with mental illness and may also improve negative symptoms. “A useful approach in clinical practice is to increase activity levels, especially physical activities like walking and gardening.”
Dr. Keshavan said he would like to see future research that focuses on whether an intervention such as aerobic exercise would improve sleep quality as well as negative symptoms.
He also said that future research should ideally examine the characteristics of sleep alterations in schizophrenia.
“For example, while sleep duration is increased in schizophrenia, studies suggest that time spent in deep sleep is reduced; sleep spindles, which are important for consolidating memory during sleep, are also reduced. Correcting these deficits may improve negative symptoms and cognitive deficits,” he added.
The study was funded by the Italian Ministry of Health and the National Institute of Mental Health. There were no conflicts of interest.

It is important to add variety into the mix – getting people to engage in different activities at different times of day would likely help residential SSD patients overcome negative symptoms of the disorder.
Although participants were recruited in Italy, Dr. Ferrarelli said he believes the findings are generalizable.
Bidirectional relationship?
Commenting on the findings, Matcheri Keshavan, MD, professor of psychiatry at Harvard Medical School in Boston, said the results are consistent with “well-known clinical observations that SSD patients tend to spend more time in bed and have more dysregulated sleep.
“Negative symptoms are also common, especially in residential patients. However, it is difficult to determine causality, as we do not know whether excessive sleepiness and decreased physical activity cause negative symptoms, or vice versa, or whether this is a bidirectional relationship,” Dr. Keshavan said.
He emphasized that physical exercise is known to increase sleep quality for people with mental illness and may also improve negative symptoms. “A useful approach in clinical practice is to increase activity levels, especially physical activities like walking and gardening.”
Dr. Keshavan said he would like to see future research that focuses on whether an intervention such as aerobic exercise would improve sleep quality as well as negative symptoms.
He also said that future research should ideally examine the characteristics of sleep alterations in schizophrenia.
“For example, while sleep duration is increased in schizophrenia, studies suggest that time spent in deep sleep is reduced; sleep spindles, which are important for consolidating memory during sleep, are also reduced. Correcting these deficits may improve negative symptoms and cognitive deficits,” he added.
The study was funded by the Italian Ministry of Health and the National Institute of Mental Health. There were no conflicts of interest.

Obstructive sleep apnea linked to early cognitive decline
In a pilot study out of King’s College London, participants with severe OSA experienced worse executive functioning as well as social and emotional recognition versus healthy controls.
Major risk factors for OSA include obesity, high blood pressure, smoking, high cholesterol, and being middle-aged or older. Because some researchers have hypothesized that cognitive deficits could be driven by such comorbidities, the study investigators recruited middle-aged men with no medical comorbidities.
“Traditionally, we were more concerned with sleep apnea’s metabolic and cardiovascular comorbidities, and indeed, when cognitive deficits were demonstrated, most were attributed to them, and yet, our patients and their partners/families commonly tell us differently,” lead investigator Ivana Rosenzweig, MD, PhD, of King’s College London, who is also a consultant in sleep medicine and neuropsychiatry at Guy’s and St Thomas’ Hospital, London, said in an interview.
“Our findings provide a very important first step towards challenging the long-standing dogma that sleep apnea has little to do with the brain – apart from causing sleepiness – and that it is a predominantly nonneuro/psychiatric illness,” added Dr. Rosenzweig.
The findings were published online in Frontiers in Sleep.
Brain changes
The researchers wanted to understand how OSA may be linked to cognitive decline in the absence of cardiovascular and metabolic conditions.
To accomplish this, the investigators studied 27 men between the ages of 35 and 70 with a new diagnosis of mild to severe OSA without any comorbidities (16 with mild OSA and 11 with severe OSA). They also studied a control group of seven men matched for age, body mass index, and education level.
The team tested participants’ cognitive performance using the Cambridge Neuropsychological Test Automated Battery and found that the most significant deficits for the OSA group, compared with controls, were in areas of visual matching ability (P < .0001), short-term visual recognition memory, nonverbal patterns, executive functioning and attentional set-shifting (P < .001), psychomotor functioning, and social cognition and emotional recognition (P < .05).
On the latter two tests, impaired participants were less likely to accurately identify the emotion on computer-generated faces. Those with mild OSA performed better than those with severe OSA on these tasks, but rarely worse than controls.
Dr. Rosenzweig noted that the findings were one-of-a-kind because of the recruitment of patients with OSA who were otherwise healthy and nonobese, “something one rarely sees in the sleep clinic, where we commonly encounter patients with already developed comorbidities.
“In order to truly revolutionize the treatment for our patients, it is important to understand how much the accompanying comorbidities, such as systemic hypertension, obesity, diabetes, hyperlipidemia, and other various serious cardiovascular and metabolic diseases and how much the illness itself may shape the demonstrated cognitive deficits,” she said.
She also said that “it is widely agreed that medical problems in middle age may predispose to increased prevalence of dementia in later years.
Moreover, the very link between sleep apnea and Alzheimer’s, vascular and mixed dementia is increasingly demonstrated,” said Dr. Rosenzweig.
Although women typically have a lower prevalence of OSA than men, Dr. Rosenzweig said women were not included in the study “because we are too complex. As a lifelong feminist it pains me to say this, but to get any authoritative answer on our physiology, we need decent funding in place so that we can take into account all the intricacies of the changes of our sleep, physiology, and metabolism.
“While there is always lots of noise about how important it is to answer these questions, there are only very limited funds available for the sleep research,” she added.
Dr. Rosenzweig’s future research will focus on the potential link between OSA and neuroinflammation.
In a comment, Liza Ashbrook, MD, associate professor of neurology at the University of California, San Francisco, said the findings “add to the growing list of negative health consequences associated with sleep apnea.”
She said that, if the cognitive changes found in the study are, in fact, caused by OSA, it is unclear whether they are the beginning of long-term cognitive changes or a symptom of fragmented sleep that may be reversible.
Dr. Ashbrook said she would be interested in seeing research on understanding the effect of OSA treatment on the affected cognitive domains.
The study was funded by the Wellcome Trust. No relevant financial relationships were reported.

FROM FRONTIERS IN SLEEP
Alzheimer’s drug may ease hair pulling, skin-picking disorders
Results from the double-blind, placebo-controlled trial showed that 61% of participants who received memantine were “much or very much improved,” versus 8% in the placebo group.
“Memantine was far more effective than placebo,” lead investigator Jon Grant, MD, MPH, professor of psychiatry and behavioral neuroscience at the University of Chicago, said in an interview. “However, while subjects responded favorably, that didn’t necessarily mean there were no symptoms.”
The study was published online in the American Journal of Psychiatry.
Underrecognized, disabling
The investigators noted that trichotillomania and skin-picking disorder are underrecognized and are often disabling conditions. However, the researchers pointed out that with prevalence rates of 1.7% for trichotillomania and 2.1% for skin-picking disorder, they are not uncommon.
Behavioral therapy that attempts to reverse these habits is considered first-line treatment, but trained therapists are difficult to find. In addition, the investigators wrote that currently, there are no Food and Drug Administration–approved medications for either disorder, and pharmacologic clinical trials are relatively uncommon.
The existing data from double-blind, placebo-controlled studies support the use of the antipsychotic olanzapine, the tricyclic antidepressant clomipramine, and the supplement N-acetyl-L-cysteine (NAC). Dr. Grant also noted that previous drug trials involving patients with trichotillomania have been very short in duration.
Prior research has implicated the glutamate system in repetitive motor habits and the urges that drive them. Memantine, a glutamate receptor antagonist, targets excessive glutamatergic drive. To investigate whether this medication may be beneficial for patients with trichotillomania and skin-picking disorders, the investigators conducted a randomized placebo-controlled trial.
The study included 100 adults (86 women; mean age, 31.4) with trichotillomania, skin-picking disorder, or both; participants received memantine (n = 55) or placebo (n = 45) for 8 weeks; they received memantine 10 mg or placebo for the first 2 weeks, then 20 mg for the next 6 weeks.
The researchers, who were blinded to assignment, assessed participants every 2 weeks using the National Institute of Mental Health Trichotillomania Symptom Severity Scale, which was modified to include questions for skin-picking disorder.
The team also tracked symptoms and behaviors using additional scales, including the Sheehan Disability Scale and the Clinical Global Impressions severity scale.
At the study’s conclusion, 79 patients remained. Of those, 26 of the 43 participants in the memantine group were “very much” or “much” improved (61%), versus 3 of 36 (8%) in the placebo group. (P < .0001)
Six participants in the memantine group experienced complete remission of symptoms, compared with one in the placebo group. There were no differences between the study groups in terms of adverse events.
Study limitations included the relatively short length of the trial for what should be considered a chronic disease, as well as the inclusion of only mildly to moderately symptomatic participants.
Dr. Grant said that he would like to study how memantine works in combination with behavioral therapy.
‘Two great options’
Katharine Phillips, MD, professor of psychiatry at Weill Cornell Medicine, New York, said she has been using memantine for “quite some time” to treat her patients with skin-picking disorder, adding that she uses higher doses of the drug than were tested in the study.
She noted that both NAC and memantine affect glutamate, an amino acid in the brain that is likely involved in repetitive physical or motor habits, such as hair pulling and skin picking.
“The good news is that we have two great options” for the treatment of trichotillomania and skin-picking disorder, said Dr. Phillips, and that both are easy to tolerate.
Future research should focus on longer trials of memantine and at higher doses, as well as other glutamate modulators, she said.
The study was funded by departmental research funds at the University of Chicago. Dr. Grant reported receiving research funding from Biohaven Pharmaceuticals and Janssen, as well as yearly compensation from Springer Publishing for his role as editor-in-chief of the Journal of Gambling Studies. He has also received royalties from American Psychiatric Publishing, McGraw Hill, Oxford University Press, and WW Norton. Dr. Phillips reported receiving royalties from American Psychiatric Publishing and an honorarium from the Merck Manual.

Four PTSD blood biomarkers identified
“More accurate means of predicting or screening for PTSD could help to overcome the disorder by identifying individuals at high risk of developing PTSD and providing them with early intervention or prevention strategies,” said study investigator Stacy-Ann Miller, MS.
She also noted that the biomarkers could be used to monitor treatment for PTSD, identify subtypes of PTSD, and lead to a new understanding of the mechanisms underlying PTSD.
The findings were presented at Discover BMB, the annual meeting of the American Society for Biochemistry and Molecular Biology.
Toward better clinical assessment
The findings originated from research conducted by the Department of Defense–initiated PTSD Systems Biology Consortium. The consortium’s goals include developing a reproducible panel of blood-based biomarkers with high sensitivity and specificity for PTSD diagnosis and is made up of about 45 researchers, led by Marti Jett, PhD, Charles Marmar, MD, and Francis J. Doyle III, PhD.
The researchers analyzed blood samples from 1,000 active-duty Army personnel from the 101st Airborne at Fort Campbell, Ky. Participants were assessed before and after deployment to Afghanistan in February 2014 and are referred to as the Fort Campbell Cohort (FCC). Participants’ age ranged from 25 to 30 and approximately 6% were female.
Investigators collected blood samples from the service members and looked for four biomarkers: glycolytic ratio, arginine, serotonin, and glutamate. The team then divided the participants into four groups – those with PTSD (PTSD Checklist score above 30), those who were subthreshold for PTSD (PTSD Checklist score 15-30), those who had high resilience, and those who had low levels of resilience.
The resilience groups were determined based on answers to the Generalized Anxiety Disorder Questionnaire, Patient Health Questionnaire, Pittsburgh Sleep Quality Index, Intensive Combat Exposure (DRRI-D), the number of deployments, whether they had moderate or severe traumatic brain injury, and scores on the Alcohol Use Disorders Identification Test.
Those who scored in the high range at current or prior time points or who were PTSD/subthreshold at prior time points were placed in the low resilience group.
Ms. Miller noted that those in the PTSD group had more severe symptoms than those in the PTSD subthreshold group based on the longitudinal clinical assessment at 3-6 months, 5 years, and longer post deployment. The low resilience group had a much higher rate of PTSD post deployment than the high resilience group.
Investigators found participants with PTSD or subthreshold PTSD had significantly higher glycolic ratios and lower arginine than those with high resilience. They also found that those with PTSD had significantly lower serotonin and higher glutamate levels versus those with high resilience. These associations were independent of factors such as sex, age, body mass index, smoking, and caffeine consumption.
Ms. Miller said that the study results require further validation by the consortium’s labs and third-party labs.
“We are also interested in determining the most appropriate time to screen soldiers for PTSD, as it has been noted that the time period where we see the most psychological issues is around 2-3 months post return from deployment and when the soldier is preparing for their next assignment, perhaps a next deployment,” she said.
She added that previous studies have identified several promising biomarkers of PTSD. “However, like much of the research data, the study sample was comprised mainly of combat-exposed males. With more women serving on the front lines, the military faces new challenges in how combat affects females in the military,” including sex-specific biomarkers that will improve clinical assessment for female soldiers.
Eventually, the team would also like to be able to apply their research to the civilian population experiencing PTSD.
“Our research is anticipated to be useful in helping the medical provider select appropriate therapeutic interventions,” Ms. Miller said.

The consortium’s goals include developing a reproducible panel of blood-based biomarkers with high sensitivity and specificity for PTSD diagnosis and is made up of about 45 researchers, led by Marti Jett, PhD, Charles Marmar, MD, and Francis J. Doyle III, PhD.
The researchers analyzed blood samples from 1,000 active-duty Army personnel from the 101st Airborne at Fort Campbell, Ky. Participants were assessed before and after deployment to Afghanistan in February 2014 and are referred to as the Fort Campbell Cohort (FCC). Participants’ age ranged from 25 to 30 and approximately 6% were female.
Investigators collected blood samples from the service members and looked for four biomarkers: glycolytic ratio, arginine, serotonin, and glutamate. The team then divided the participants into four groups – those with PTSD (PTSD Checklist score above 30), those who were subthreshold for PTSD (PTSD Checklist score 15-30), those who had high resilience, and those who had low levels of resilience.
The resilience groups were determined based on answers to the Generalized Anxiety Disorder Questionnaire, Patient Health Questionnaire, Pittsburgh Sleep Quality Index, Intensive Combat Exposure (DRRI-D), the number of deployments, whether they had moderate or severe traumatic brain injury, and scores on the Alcohol Use Disorders Identification Test.
Those who scored in the high range at current or prior time points or who were PTSD/subthreshold at prior time points were placed in the low resilience group.
Ms. Miller noted that those in the PTSD group had more severe symptoms than those in the PTSD subthreshold group based on the longitudinal clinical assessment at 3-6 months, 5 years, and longer post deployment. The low resilience group had a much higher rate of PTSD post deployment than the high resilience group.
Investigators found participants with PTSD or subthreshold PTSD had significantly higher glycolic ratios and lower arginine than those with high resilience. They also found that those with PTSD had significantly lower serotonin and higher glutamate levels versus those with high resilience. These associations were independent of factors such as sex, age, body mass index, smoking, and caffeine consumption.
Ms. Miller said that the study results require further validation by the consortium’s labs and third-party labs.
“We are also interested in determining the most appropriate time to screen soldiers for PTSD, as it has been noted that the time period where we see the most psychological issues is around 2-3 months post return from deployment and when the soldier is preparing for their next assignment, perhaps a next deployment,” she said.
She added that previous studies have identified several promising biomarkers of PTSD. “However, like much of the research data, the study sample was comprised mainly of combat-exposed males. With more women serving on the front lines, the military faces new challenges in how combat affects females in the military,” including sex-specific biomarkers that will improve clinical assessment for female soldiers.
Eventually, the team would also like to be able to apply their research to the civilian population experiencing PTSD.
“Our research is anticipated to be useful in helping the medical provider select appropriate therapeutic interventions,” Ms. Miller said.

Exercise tied to reduced Parkinson’s motor symptoms and increased well-being
A systematic review of 156 clinical trials involving 8,000 patients with Parkinson’s disease showed dancing and aquatic exercise, in particular, were most likely to improve motor symptoms, while swimming, endurance training, and mind-body training were most likely to benefit quality of life.
“For most types of exercise we studied, we observed positive effects on both the severity of motor signs and quality of life. These results highlight the importance of exercise in general, as they suggest people with Parkinson’s disease can benefit from a variety of exercises,” said study investigator Moritz Ernst, MSc, deputy head of the working group on evidence-based medicine at the University Hospital Cologne (Germany).
“Clinicians and people with Parkinson’s disease may have several options of exercise programs to choose from when establishing an individual training routine,” he added, emphasizing that overall those with Parkinson’s disease should seek professional advice, including assessment of motor and nonmotor symptoms, to develop a training agenda based on their individual needs.
The study was published online in the Cochrane Database of Systematic Reviews.
May I have this dance?
The investigators analyzed data from randomized, controlled trials comparing different types of exercise and no exercise and the subsequent effect on Parkinson’s disease symptoms. Exercise included dance, strength-resistance training, mind-body training such as tai chi and yoga, water-based training, resistance training, gait/balance/functional training, and endurance training.
The average age of study participants ranged from 60 to 74 years, and most of the studies included patients with mild to moderate Parkinson’s disease. The mean length of the various interventions was 12 weeks.
When the researchers examined the effect of exercise on motor symptoms, they found that dance (P = .88), aqua-based training (P = .69), and gait/balance/functional training (P = .67) were most likely to reduce symptom severity.
Aqua-based training (P = .95), endurance training (P = .77), and mind-body training (P = .75) were most were most likely to benefit quality of life, although the investigators caution that these findings were at risk of bias because quality of life was self-reported.
The investigators noted other study limitations including the fact that most of the studies included in the review had small sample sizes and their study only included patients with mild to moderate versus severe Parkinson’s disease.
The authors said that future research should include larger samples, report intent-to-treat analyses, and involve participants with more advanced forms of Parkinson’s disease who may also have cognitive difficulties.
Prescribe exercise
“We should be giving our patients, no matter where they are in their disease stage, a ‘prescription’ to exercise,” said Mitra Afshari, MD, MPH. Dr. Afshari was not involved in the study but leads her own research on Parkinson’s disease and exercise as the site principal investigator on the National Institutes of Health–funded SPARX3 Study in Parkinson’s Disease and Exercise at Rush University in Chicago. She said that, based on her experience caring for patients with Parkinson’s disease at all disease stages, “patients who have been physically active their whole lives and can maintain that activity despite their diagnosis fare the best.”
However, she added, those who initiate physical exercise after diagnosis can also do very well and reap benefits, including improved motor symptoms.
The study was funded by University Hospital of Cologne, Faculty of Medicine and University Hospital, University of Cologne, and the German Ministry of Education and Research. The authors have disclosed no relevant financial relationships.
