What is attention deficit hyperactivity disorder (ADHD)?
Top
ADHD refers to a chronic bio behavioral disorder that initially manifests in childhood and is characterized by
Hyperactivity, Impulsivity, Inattention. Not all of those affected by ADHD manifest all three behavioral categories. These symptoms can lead to difficulty in academic, emotional, and social functioning.
