Teens may have mania without depression, making their bipolar illness harder to classify, according to a new NIMH study. Interviews with 10,213 teens found that 2.5 percent met criteria for bipolar disorder, a rate similar to that of adults, but 1.7 percent had mania only without the depression.
Bipolar Teens may Have Mania but no Depression
Note from Kermit Cole, “In the News” editor:
The authors suggest in the “implications” section: “In fact, the lack of evidence of mania alone in clinical samples of both youth and adults could be attributable to the high frequency of behavioral disturbances that emerge as a consequence of mania that may obfuscate the core manifestations of mania. Follow-up of this sample is critical to distinguish characteristics of youth with transient manic episodes from those for whom mania signals early manifestations of recurrent mood disturbances including bipolar disorder and its lifelong consequences.”
