While scientists aren’t sure exactly what causes ADHD, they think it’s likely caused by a combination of genes, environment, and slight differences in how the brain is hardwired. If you were diagnosed with childhood ADHD or ADD, chances are you’ve carried at least some of the symptoms into adulthood. But even if you were never diagnosed as a child, that doesn’t mean ADHD can’t affect you as an adult.

ADHD in adults can be caused by a combination of genes, environment, and brain differences, and can affect individuals regardless of their childhood diagnosis.
