Newest firstBackground The endocannabinoid system (ES) plays a pivotal role in modulating central nervous system activity in response to emotional stimuli. This study aimed to identify and validate biomarkers associated with ES-related genes (ES-RGs) in major depressive disorder (MDD), providing insights into potential therapeutic targets. Methods Datasets GSE52790 and GSE38206 were analyzed in this study. Overlapping differe…
Background Cannabis is one of the most commonly used drugs globally, although its legal status varies across regions. Public support for its decriminalization has increased, but gaps in our understanding of the health consequences of cannabis use remain, particularly related to its impact on mental health. This article provides an updated systematic review and meta-analysis (previous being Lev-Ran et al., ) lookin…
The role of the endocannabinoid system (ECS) in major depressive disorder (MDD) is under-investigated despite reports of increased activity and/or concentration of fatty acid amide hydrolase (FAAH), a key ECS enzyme, in fronto-limbic brain regions in some animal models of depressive behavior. We hypothesized that [11C]CURB λk3, an index of FAAH density, would be elevated in the prefrontal cortex, hippocampus, and…
Introduction Nitrous oxide (N2O) is used for anesthetic purposes but has gained popularity as a recreational substance. Despite its potentially severe adverse effects, knowledge about N2O use within psychiatric populations is limited. This study aimed to evaluate the life-time prevalence and patterns of N2O consumption among patients with psychiatric disorders. Methods A retrospective observational cohort study wa…
Background Rapid changes in attitudes, legality, and patterns of cannabis use (CU) underscore the importance of understanding its impact on mental health. Although links between CU and personality disorders (PDs) are documented, their causality remains uncertain. Methods Employing Genome-Wide Association Studies (GWAS) data, this study investigated the causal relationship between cannabis use disorder (CUD) and li…
Though significant research highlights higher rates of mental ill-health and substance use among trans, non-binary and gender diverse (henceforth 'trans') young people, little research has considered patterns, contextual characteristics, and correlates of co-occurring experiences of mental ill-health and substance use among trans young people. Using data from the Trans Pathways study, we used prevalence ratios and…
Emerging evidence suggests that glucagon-like peptide-1 receptor (GLP1R) agonists may have potential benefits for mental illnesses. However, their exact effects remain unclear. This study investigated the causal relationship between glucagon-like peptide-1 receptor agonist (GLP1RA) and the risk of 10 common mental illnesses, including attention deficit and hyperactivity disorder, anorexia nervosa, anxiety disorder…
Background The sensory-motor network is essential for integrating sensory input with motor function and higher-order cognition. Resting-state functional connectivity (rsFC) within this network undergoes significant developmental changes, and disruptions in these connections have been linked to behavioral and psychiatric outcomes. However, the relationship between sensory-motor connectivity, early-life adversity, a…
Introduction Adverse childhood experiences (ACEs) have been linked to chronic health conditions, at-risk behaviors, and reduced quality and length of life. Public health interventions targeting childhood trauma require an investigation of overall prevalence of ACEs and associations with outcomes and behaviors. Methods We created an ACE score using aggregated North Dakota (ND) Behavioral Risk Factor Surveillance Sy…
Abstract Background People living with HIV experience high rates of mental health disorders, but the comorbidity patterns of these conditions remain poorly understood. Identifying how disorders cluster and which diagnoses are most central may guide more effective screening and integrated treatment strategies. Methods This cross-sectional study used electronic health records and survey data from the National Instit…
Background and aims The co-occurrence of behavioral addictions (BAs) and substance use disorders (SUDs) or other mental health problems (MHPs) is well documented. However, there is limited evidence on associations between changes in the severity of BAs, SUDs, and MHPs, or their directions of influence or causation. Methods A non-self-selecting sample of 5,611 young Swiss men (mean age 25.5 at baseline and 28.3 at…
Major depressive disorder (MDD) exhibits substantial neurobiological heterogeneity that complicates treatment selection and mechanistic understanding. While conventional group-level analyses identify diverse structural alterations, they obscure clinically relevant individual differences. We employed heterogeneity through discriminant analysis (HYDRA) clustering to decompose morphometric inverse divergence (MIND) n…
Introduction Tobacco and other substance co-use has not been examined in adolescent and young adult (AYA) cancer survivors. We compared the prevalence of past-month co-use of tobacco+cannabis, alcohol and illicit drugs between AYAs with and without a cancer history and considered associations between co-use and nicotine dependence in AYA cancer survivors who use tobacco, exploring if past-year major depression mod…
Background Cannabis use is elevated in youth with depression and attention-deficit/hyperactivity disorder (ADHD), but drivers of this increase remain underexplored. The self-medication hypothesis suggests cannabis is used by patients for mood regulation, a common difficulty in ADHD and depression. This study aimed to examine associations between mood instability and cannabis use in a large, representative clinical…
Technological devices play a central role in adolescents' life. Despite concerns about negative effects of excessive screen time, there is little knowledge of screen behaviors' genetic architecture. Using self-reports from adolescents in the Norwegian Mother, Father, and Child Cohort Study (n = 18,490), we performed genome-wide association analysis for four screen behaviors: time spent (1) watching television; (2)…
Background and aim Major depressive disorder is a prevalent psychiatric condition associated with impaired neuroplasticity, particularly in the hippocampus. Although selective serotonin reuptake inhibitors (SSRIs) are commonly prescribed, their delayed onset and adverse effects highlight the need for alternative therapies. Cannabidiol (CBD), a non-psychotomimetic cannabinoid, has shown antidepressant-like properti…
Background Sexual and gender minority (SGM) youth are at elevated risk for adverse mental health and substance use outcomes. Stressors such as family conflict, discrimination, and trauma have been suggested as possible mediators of these disparities. Aims This study examined whether family conflict, discrimination, and trauma mediate the associations between SGM identity and adverse outcomes, including suicide att…
BACKGROUND: The corpus callosum (CC) is a brain structure with a high heritability and potential role in psychiatric disorders. However, the genetic architecture of the CC and the genetic link with psychiatric disorders remain largely unclear. We investigated the genetic architectures of the volume of the CC and its subregions and the genetic overlap with psychiatric disorders. METHODS: We applied multivariate gen…
Introduction This study provides a descriptive overview of the prevalence of posttraumatic stress disorder (PTSD) in Canada, across sociodemographic characteristics, mental health-related variables and negative impacts of the COVID-19 pandemic. Methods Data were obtained from cycles 1 and 2 of the Survey on COVID-19 and Mental Health (SCMH), collected in fall 2020 (N = 14 689) and spring 2021 (N = 8032). The preva…
Background Depression is a prevalent and disabling disorder that poses serious problems in mental health care, and rapid antidepressants are novel treatments for this disorder. Cannabidiol (CBD), a nonintoxicating phytocannabinoid, is thought to have therapeutic potential due to its important neurological and anti-inflammatory properties. Despite major advances in pharmacotherapy in experimental animals, the exact…
