Reuters (5/9, Grens) reports that according to a study published online May 7 in the Archives of General Psychiatry, the number of adolescents who experience mania appears to be similar to that of adults with bipolar disorder. After analyzing data on some 10,000 adolescents who were extensively interviewed regarding their behavior and their moods, researchers found that 2.5% of the teens had met diagnostic criteria for both depression and mania within the past 12 months. This compares to National Institute of Mental Health statistics on adults, which found that 2.6% also had symptoms of bipolar disorder within the previous year. The study authors concluded that for many young people, bipolar disorder may begin during their teen years.
