"About 7 Percent of Kids Worldwide Have ADHD: Study"
About 7 percent of children worldwide have attention-deficit/hyperactivity disorder (ADHD), new research concludes. This estimate -- which differs significantly from other recent appraisals -- is based on data from 175 prior studies conducted over nearly four decades. Critics say there may be serious problems with the way the researchers came to their conclusions, noting the research pools together dozens of studies that used a wide variety of criteria to determine whether children had ADHD. For example, the study pools prior results based on diagnostic criteria that varied among three versions of the Diagnostic and Statistical Manual of Mental Disorders, the "bible" used by mental health professionals, said Eyal Shemesh, MD, chief of behavioral and developmental health at the Kravis Children's Hospital at Mount Sinai in New York City.
