The Role of Cognitive Disengagement Syndrome Symptoms in the Association Between ADHD Symptoms and Sleep Problems: Findings from An Epidemiological Survey

Cognitive Disengagement Syndrome (CDS), a transdiagnostic construct characterized by sluggishness and daydreaming, was associated with Attention-Deficit/ Hyperactivity Disorder (ADHD). Our study investigated the mediating role of CDS in the relationship between ADHD and sleep disturbances in a Turkish epidemiological sample.
