The percentage of children diagnosed with attention deficit-hyperactivity disorder or ADHD in the U.S. has increased in the past decade, according to a new report.
The percentage of children who had ever received a diagnosis of ADHD had increased from about 7 per cent in the 1998-2000 period to 9 per cent in 2007-2009, the August issue of the National Center for Health Statistics Data Brief said.
