Because its scope, projected popularity, immersivity, may pose unique opportunities risks for mental health.

Precision psychiatry has emerged as part of the shift to personalized medicine and builds on frameworks such U.S. National Institute Mental Health Research Domain Criteria (RDoC), multilevel biological “omics” data and, most recently, computational psychiatry. The is prompted by realization that a one-size-fits all approach inadequate guide clinical care because people differ in ways are not captured broad diagnostic categories. One first steps developing this treatment was use genetic...
This study investigates the clinical utility of rhythmic digital markers (RDMs) in schizophrenia. RDMs are capturing behavioral rhythms over different timescales - within 24 hours span (ultradian), at a (circadian), or cycles more than (infradian). While previous research has explored for schizophrenia, focus primarily been on sensor data variability rather patterns. introduces two RDMs: an entropy RDM, which quantifies uncertainty activity distribution infradian cycles, and dynamic is...
Background and aims: Problematic gaming has been linked to increased levels of psychotic-like experiences (PLEs) in youth, but the role environmental factors remains unclear. Using affordance theory, this study aimed examine association problematic with PLEs factors. Methods: Participants were 6492 youth (39.2% female) who reported playing video games, from Adolescent Brain Cognitive Development Study U.S. Measures included gaming, peer environment (number close friends), school (teachers,...
<h3>Importance</h3> Household food insecurity has been associated with mental health problems in children independently of family income and other confounders.

Abstract Background Expressive writing requires journaling stressor-related thoughts and feelings over four daily sessions of 15 min. Thirty years research have popularized expressive as a brief intervention for fostering trauma-related resilience; however, its ability to surpass placebo remains unclear. This study aimed determine the efficacy improving post-traumatic stress symptoms in perinatal women who were living Houston area during major flooding caused by Hurricane Harvey. Methods A...
Across subthreshold psychotic and nonpsychotic syndromes, symptoms experienced before the onset of a first episode psychosis (FEP) may index distinct illness trajectories. We aimed to examine associations between three types pre-onset (self-harm, suicide attempts, psychotic) outcome trajectories during FEP. Participants with FEP were recruited from PEPP-Montreal, catchment-based early intervention service. Pre-onset systematically assessed through interviews participants (and their...
Abstract The stress-vulnerability model has been repeatedly highlighted in relation to the risk, onset and course of psychosis, independently studied clinical high-risk (CHR) first-episode psychosis (FEP) populations. Notable this literature, however, is that there are few studies directly comparing markers stress response across progressive stages illness. Here we examined psychobiological Trier Social Stress Test 28 CHR (mean age 19.1) 61 FEP (age 23.0) patients, order understand stage(s)...
Abstract Young people are worried about climate change but the association with current and past mental health symptoms is rarely examined in longitudinal population-based samples. Drawing on a birth cohort from Canadian province of Quebec ( n = 1325), this study used cross-over design to (1) test between worry at age 23-years concurrent assessed standardised instruments, (2) adolescent (15 17 years) anxiety, depression, inattention-hyperactivity, aggression-opposition 23-years. Participant...
Abstract Background and Hypothesis Symptoms that precede a first episode of psychosis (FEP) can ideally be targeted by early intervention services with the aim preventing or delaying onset. However, these precursor symptoms emerge in combinations sequences do not rest fully within traditional diagnostic categories. To advance our understanding illness trajectories preceding FEP, we aimed to investigate temporal associations among symptoms. Study Design Participants were from PEPP-Montréal,...
Paranoia is a spectrum of fear-related experiences that spans diagnostic categories and influenced by social cognitive factors. The extent to which media other types use are associated with paranoia remains unclear.

The frontal variant of Alzheimer disease (fvAD) is characterized by behavioral and/or dysexecutive impairments that can resemble those behavioral-variant frontotemporal dementia (bvFTD). This overlap, in addition to the lack consensus clinical criteria for fvAD, complicates its identification. We provide first case report fvAD differentiated vivo from bvFTD using amyloid-beta and tau PET imaging. patient, a right-handed woman, presented with forgetfulness at age 60. Cognitive testing time...
While health needs in Nunavik are distinct, there is a scarcity of knowledge transfer intended for local primary care providers. We aimed to build an information tool the form newsletter and website share with them selection relevant research articles. To identify such articles, scoping study Inuit published between 2012 2017 was conducted. Selection criteria were adapted from framework mastery. After database search yielding 2896 results, publications screened eligibility. Next, 226...
