Supplementary — Child and Adolescent Psychiatry (Neurodevelopmental Disorders)

1. Overview & Epidemiology

Neurodevelopmental disorders (DSM-5-TR chapter; ICD-10 F70–F98) are a group of conditions with onset in the early developmental period, producing deficits that impair personal, social, academic, or occupational functioning. They include: intellectual developmental disorder, communication disorders, autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), specific learning disorder, motor disorders (incl. tic disorders / Tourette), and stereotypic movement disorder. Selective mutism is classified with the anxiety disorders, not here — a frequent exam point.
