Newest firstEpigenetic mechanisms are thought to contribute to neurodevelopmental vulnerability for psychiatric disorders, yet longitudinal evidence linking DNA methylation (DNAm) to brain maturation and psychopathology is limited. Using epigenome-wide DNAm (372,582 CpGs) and whole-brain structural MRI data from the IMAGEN cohort (n = 506, ages 14–19), we identified 18 co-regulated DNAm clusters, ten enriched for brain-expres…
Open article record in new tab ↗Globally, cannabis ranks third in psychoactive substance prevalence after nicotine and alcohol, with heavy use linked to psychosis, anxiety, and depression. However, real-time data on how legal reforms influence consumption remain scarce. This Ecological Momentary Assessment (EMA) study analyzed daily cannabis use patterns before and after Germany's recreational cannabis decriminalization in April 2024 in 49 indiv…
Rationale For decades, cannabis has been the most widely used illicit substance in the world, particularly among youth. Research suggests that mental health problems associated with cannabis use may result from its effect on reward brain circuit, emotional processes, and cognition. However, findings are mostly derived from correlational studies and inconsistent, particularly in adolescents. Objectives and methods…
Open article record in new tab ↗Substance use, including cigarettes and cannabis, is associated with poorer sustained attention in late adolescence and early adulthood. Previous studies were predominantly cross-sectional or under-powered and could not indicate if impairment in sustained attention was a predictor of substance-use or a marker of the inclination to engage in such behaviour. This study explored the relationship between sustained att…
Open article record in new tab ↗BackgroundIt has not yet been determined if the commonly reported cannabis–psychosis association is limited to individuals with pre-existing genetic risk for psychotic disorders.MethodsWe examined whether the relationship between polygenic risk score for schizophrenia (PRS-Sz) and psychotic-like experiences (PLEs), as measured by the Community Assessment of Psychic Experiences-42 (CAPE-42) questionnaire, is mediat…
Open article record in new tab ↗While there is substantial evidence that cannabis use is associated with differences in human brain development, most of this evidence is correlational in nature. Bayesian causal network (BCN) modeling attempts to identify probable causal relationships in correlational data using conditional probabilities to estimate directional associations between a set of interrelated variables. In this study, we employed BCN m…
Open article record in new tab ↗Ziel der StudieIm Zuge der Minimierungsabsichten von Zwangsmaßnahmen ist ein gutes Verständnis für deren Einflussfaktoren elementar. Die vorliegende Arbeit untersucht den Zusammenhang zwischen Substanzkonsum und der Anwendung von Zwangsmaßnahmen.MethodenAlle im Jahr 2019 durchgeführten Zwangsmaßnahmen der akutpsychiatrischen Stationen der Charité Campus Mitte wurden untersucht, mit Fokus auf den Zusammenhang mit S…
Open article record in new tab ↗Genetic markers of the endocannabinoid system have been linked to a variety of addiction-related behaviors that extend beyond cannabis use. In the current study we investigate the relationship between endocannabinoid (eCB) genetic markers and alcohol use disorder (AUD) in European adolescents (14-18 years old) followed in the IMAGEN study (n = 2,051) and explore replication in a cohort of North American adolescent…
