The Mixed Episode

Criteria for Mixed Episode based on American Psychiatric Association DSM-IV

  • The criteria are met for a Manic Episode and for a Major Depressive Episode (except for the duration) nearly every day during at least a 1-week period.
  • The mood disturbance is sufficiently severe to cause marked impairement in occupational functioning or in usual social activities or relationships with others, or to necessitate hospitalization to prevent harm to self or others, or there are psychotic features.
  • The symptoms are not due to the direct physiological effects of a sub- stance (e.g., a drug of abuse, a medication, or other treatment) or a general medical condition (e.g., hyperthyroidism).

Note: Mixed-like episodes that are clearly caused by somatic antidepressant treatment (e.g., medication, electroconvulsive therapy, light therapy) should not count toward a diagnosis of Bipolar I Disorder.
