What causes hyperactive-impulsive ADHD?

ANSWER

The causes of ADHD aren't clear. Scientists say it is due in large part to genes that are passed down from parent to child, but experts aren't sure yet which specific genes make it more likely to get ADHD. A child is more likely to have ADHD if a close family member has it.
