Technically not a disorder in and of itself. Mixed episodes are part of
Bipolar Disorders.
DSM-IV Criteria
A. The criteria are met both for a
Manic Episode and for a
Major Depressive Episode (except for duration) nearly every day during at least a 1-week period.
B. The mood
disturbance is sufficiently severe to cause marked impairment 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.
C. The symptoms are not due to the direct
physiological effects of a substance (e.g., drug 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.
