Is ADHD Hereditary?

Attention deficit hyperactivity disorder (ADHD or ADD) is a brain disorder with a number of likely causes — though the medical community still can’t pinpoint exactly which one explains the symptoms of ADHD. Researchers suspect that a gene involved in the creation of dopamine, a chemical that controls the brain’s ability to maintain regular and consistent attention may be traced back to ADHD. But conclusive studies are far outnumbered by ADHD myths and misperceptions today.
ADHD is not caused by bad parenting, too much sugar, or too many video games. It is a brain-based, biological disorder. Brain imaging studies and other research show many differences in the brains of individuals with ADHD. Other studies reveal that a child with ADHD is four times as likely to have had a relative also diagnosed with the condition
