Mental health clinicians and researchers have debated about the average onset age of bipolar disorder. A study published in the May 2012 Archives of General Psychiatry may have another clue towards solving this debate. The study, led by Kathleen Ries Merikangas, Ph.D., of the National Institute of Mental Health, showed that 2.5% of the 10,123 teenagers surveyed (approx. 253 teens) met the criteria for lifetime bipolar I or bipolar II disorder.Because the percentage is so close to that of adults diagnosed with bipolar disorder (2.6%), these findings may suggest that bipolar disorder first manifests in one's teen years rather than their 20s or 30s.
