WASHINGTON - When "Fidgety Philip" grows up, the problems of attention deficit disorder can multiply into loss of nearly a month's work per year.
Long seen as a problem for children, attention deficit hyperactivity disorder was first described in 1845 by Dr. Heinrich Hoffman, who wrote "The Story of Fidgety Philip."
More recently, it has been recognized as continuing into adulthood for some people, and new research seeks to estimate the effect of ADHD on workers.
