ADHD and the Brain

Attention deficit hyperactivity disorder (ADHD) is a common behavioral disorder that emerges in children before the age of 7 and can extend into adulthood. It was discovered in 1902 and thought to be a symptom of brain damage.

The occurrence of ADHD is closely tied to biological factors such as the size and density of various brain structures and their chemical reactions.
