Diagnostic Criteria for Bipolar Disorder

Manic-depression is the common term for bipolar affective disorder. The standard classification was given by Gerald Klerman, MD, who identified six forms of bipolar disorder (Psychiatric Annals 17: Jan. 1987).

  • Bipolar I: Mania and depression.
  • Bipolar II: Hypomania and depression.
  • Bipolar III: Cyclothymic disorders.
  • Bipolar IV: Hypomania or mania precipitated by antidepressant drugs.
  • Bipolar V: Depressed patients with bipolar relatives.
  • Bipolar VI: Mania without depression.

Onset of bipolar symptoms: "Pooling the data from 22 studies reporting average onset age in bipolar affective illness, the weighted mean is 28.1 years." (Goodwin and Jamison, Manic Depressive Illness, Oxford Univ Press, 1990)
