Bipolar disorder in youths may be over-diagnosed

The diagnosis of bipolar disorder in children and adolescents has risen fortyfold since 1994, according to a study released Monday. But researchers partly attributed the dramatic rise to doctors over-diagnosing the serious psychiatric disorder.The report in the journal Archives of General Psychiatry said bipolar disorder was found in 1,003 of every 100,000 office visits from children and adolescents in 2002-03, compared with 25 of 100,000 office visits in 1994-95.The diagnosis of bipolar disorder among adults increased twofold during the same period, researchers said.
