Idea of New Attention Disorder Spurs Research, and Debate

Alan Schwarz:

With more than six million American children having received a diagnosis of attention deficit hyperactivity disorder, concern has been rising that the condition is being significantly misdiagnosed and overtreated with prescription medications.
 Yet now some powerful figures in mental health are claiming to have identified a new disorder that could vastly expand the ranks of young people treated for attention problems. Called sluggish cognitive tempo, the condition is said to be characterized by lethargy, daydreaming and slow mental processing. By some researchers’ estimates, it is present in perhaps two million children.
 Experts pushing for more research into sluggish cognitive tempo say it is gaining momentum toward recognition as a legitimate disorder — and, as such, a candidate for pharmacological treatment. Some of the condition’s researchers have helped Eli Lilly investigate how its flagship A.D.H.D. drug might treat it.
