What are two major symptoms required for a diagnosis of Attention Deficit/Hyperactivity Disorder?

For a diagnosis of Attention Deficit/Hyperactivity Disorder (ADHD), the core symptoms revolve around patterns of inattention and hyperactivity-impulsivity. The DSM-5 outlines that individuals must exhibit symptoms from both categories— inattention and hyperactivity-impulsivity—to meet the diagnostic criteria.

Inattention symptoms may include difficulties sustaining attention, following through on tasks, and organizational challenges, while hyperactivity includes excessive fidgeting, talking, or difficulty remaining seated in appropriate situations. By identifying these two major symptoms, clinicians can more accurately assess the presence of ADHD and differentiate it from other disorders that may exhibit overlapping symptoms, such as anxiety or mood disorders. This clarity is vital for determining appropriate interventions and supports for individuals with ADHD.
