Wider ADHD definition risks unnecessary medication, say experts

By Kate Kelland LONDON (Reuters) - A wider definition of attention deficit hyperactivity disorder (ADHD) is causing inappropriate diagnosis and unnecessary and possibly harmful medical treatment costing up to $500 million in the United States alone, scientists said on Wednesday. Less restrictive diagnostic criteria have contributed to a steep rise in diagnoses for the behavioral brain condition -particularly among children - the researchers said, and in the use of stimulant drugs to manage it. "The broadening of the diagnostic criteria is likely to increase what is already a significant concern about overdiagnosis," he said. "It risks resulting in a diagnosis of ADHD being regarded with skepticism, to the harm of those with severe problems who unquestionably need sensitive, skilled specialist help and support." People with the ADHD are excessively restless, impulsive and easily distracted, and children with the condition often have trouble in school.
