This document discusses attention deficit hyperactivity disorder (ADHD) by outlining potential causes, common symptoms, diagnostic criteria, and recommendations for academic accommodations. It notes that ADHD symptoms can be inattentive, hyperactive/impulsive, or a combination. Diagnosis involves assessing functioning across settings and ruling out other potential causes. Accommodations help students with challenges in attention, impulsivity, organization and compliance by providing structure, cues, praise and consequences to support their success.
