Narrator: This is Science Today. Symptoms of attention deficit hyperactivity disorder, or ADHD, usually diminish in girls as they enter adolescence. But a new University of California, Berkeley study has found that certain symptoms still plague girls between ages 12 and 17 and can cause serious problems. Psychology professor Stephen Hinshaw, who led the study, explains.
Hinshaw: Risk for delinquency, risk for depression and anxiety, risk for eating problems and substance use. Things we couldn't measure in childhood. 544 In all of the domains we measured, the girls with ADHD continued to lag behind their peers and show noticeable deficits.
Narrator: Hinshaw says that relatively little is known about ADHD in girls because it was believed that it couldn't affect them until recently.
Hinshaw: For a long time, many people, well-educated people thought, “Well ADHD doesn't really occur in girls. We don't see any girls referred to clinics for this problem.” Well one of the reasons for that was because people thought it couldn't exist in girls, they didn't diagnose it, so no one was referred.
