Understanding ADHD
Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental condition that affects millions of adults. Learn about symptoms, types, and how professional assessment can help.
What is ADHD?
ADHD is a neurodevelopmental disorder characterized by persistent patterns of inattention and/or hyperactivity-impulsivity that interfere with functioning or development.
According to the DSM-5, ADHD affects both children and adults, with symptoms that must have been present before age 12 and occur in multiple settings such as work, home, and social situations.
For adults, the diagnosis requires at least 5 symptoms from either the inattentive or hyperactive-impulsive categories, with symptoms persisting for at least 6 months.
