Association of Brain Structural Measurements and Polygenic Risk Scores with Obsessive-Compulsive Symptoms in Adolescents Diagnosed with Obsessive-Compulsive Disorder, Attention-Deficit/Hyperactivity Disorder, Anxiety, Depression, Autism and Tic Disorders.

ABSTRACT: Obsessive-compulsive symptoms, characterized by intrusive thoughts and repetitive behaviors, are prevalent among youth. These symptoms are known to be moderately heritable and linked to structural brain changes involved in their pathophysiology. This study investigates the connections between structural brain alterations (cortical thickness, surface area and subcortical volume), genetic variation, and childhood obsessive-compulsive symptom scores within 143 samples of healthy control participants and cases diagnosed with obsessive-compulsive disorder, attention-deficit/hyperactivity disorder, anxiety disorder, autism spectrum disorders and/or tic disorders. We hypothesize that the effect of genetic variants on standardized scores of obsessive-compulsive symptoms is mediated by imaging endo
