More children are getting a diagnosis of ADHD, according to a study that looked at hundreds of thousands of California medical records.
FOX News Radio's Bill Vitka reports:
The number of children with ADHD, Attention Deficit Hyperactivity Disorder, is growing and growing rapidly, rising by 24% since 2001.
Boys are three times more likely to be affected than girls. They may be more vulnerable, or it may be girls with the condition are overlooked.
As well, high-income white children are more likely to be diagnosed with ADHD, which may reflect greater concern with school performance.
The study which appears online in the journal Pediatric relied on detailed medical records by experts and not primary-care doctors.
