Causes

By Mayo Clinic staff

While the exact cause of ADHD is not clear, research efforts continue.

Multiple factors have been implicated in the development of ADHD. It can run in families, and studies indicate that genes may play a role. Certain environmental factors also may increase risk, as can problems with the central nervous system at key moments in development.
