ADHD is a neurodevelopmental disorder that affects a person's ability to pay attention, control impulsive behaviors, and regulate their activity level.

It is diagnosed in childhood and can persist into adulthood.

Symptoms of ADHD can vary from person to person, but some common signs include:

Treatment for ADHD typically involves a combination of medication and therapy.
