Researchers now say attention deficit hyperactivity disorder can occur in adults who did not show signs of ADHD as kids.
The study out of King's College London found "nearly 70 percent of the young adults with ADHD in their study did not meet criteria for the disorder at any of the childhood assessments. Adults with this 'late-onset' ADHD had high levels of symptoms, impairment and other mental health disorders."
The study was published in the Journal of the American Medical Association and examined 2,200 twins from the U.K. Researchers measured childhood ADHD symptoms at certain ages: 5, 7, 10, 12 and again as adults at 18.
