Which disorder is classified as a neurodevelopmental disorder?

• A. Obsessive-Compulsive Disorder
• B. ADHD
• C. Major Depressive Disorder
• D. Generalized Anxiety Disorder

Answer: (B)

Neurodevelopmental disorders are conditions that originate in the development of the nervous system and typically appear in childhood, affecting areas like attention, learning, language, or motor skills. ADHD fits this pattern because it involves differences in brain development that influence executive functions such as sustaining attention, regulating impulses, and controlling activity level. These differences usually show up before school age and impact functioning across multiple settings (home, school, etc.). The other conditions here are not classified as neurodevelopmental disorders. Obsessive-compulsive disorder is primarily an anxiety-related condition characterized by intrusive thoughts and repetitive behaviors, not a developmental delay or brain-based difference that emerges early in development. Major depressive disorder is a mood disorder, centered on persistent sadness and anhedonia rather than developmental disruptions in brain maturation. Generalized anxiety disorder is another anxiety condition focused on excessive worry, not a developmental disorder affecting learning or behavior from early life. So ADHD is the choice that aligns with the idea of a neurodevelopmental disorder.
