Attention Deficit Hyperactivity Disorder (ADHD) - Cause

The exact cause of attention deficit hyperactivity disorder (ADHD) isn't known. But it may run in families. Ongoing research is focused on finding the genes that cause a person to be likely to get ADHD.

A mother's use of cigarettes, alcohol, or other drugs during pregnancy may increase the risk for ADHD. Also, exposure to lead may cause symptoms linked with ADHD.1

Although many parents believe that foods with sugar and food additives make their children more hyperactive, these foods haven't been shown to cause ADHD.2
