Attention deficit hyperactivity disorder is not limited to just children; anywhere from 30% to 70% of kids with ADHD continue having symptoms when they reach adulthood. In addition, people who were never diagnosed as kids may develop symptoms in adulthood, causing trouble on the job or in relationships. Many adults don’t realize they have ADHD, leaving them puzzled about why their goals seem to slip out of reach, or why they are having problems with paying attention when they never had difficulty before.
