ATTENTION-DEFICIT / HYPERACTIVITY DISORDER
ADHD is a neuropsychiatric condition beginning during childhood that often persists into adulthood. The core feature of this condition is a persistent pattern of attention difficulties and/or hyperactivity-impulsivity that interferes with functioning. Untreated ADHD in children is associated with reduced school performance and more difficulties with peer interactions. In adults, untreated ADHD is associated with poorer occupational performance and attainment, higher chances of unemployment and increased interpersonal conflict. It is more frequent in males than in females, and females are more likely to primarily have symptoms of inattention.
Presentations of ADHD may be predominantly inattentive, predominantly hyperactive/impulsive, or combined.
