Bipolar and Related Disorders: Changes from DSM IV to DSM 5
- Diagnostic criteria for bipolar disorders now include both changes in mood and changes in activity or energy.
- The DSM-IV diagnosis of bipolar I disorder, mixed episodes—requiring that the individual simultaneously meet full criteria for both mania and major depressive episode— is replaced with a new specifier “with mixed features.”
- Particular conditions can now be diagnosed under other specified bipolar and related disorder, including categorization for individuals with a past history of a major depressive disorder whose symptoms meet all criteria for hypomania except the duration criterion is not met (i.e., the episode lasts only 2 or 3 days instead of the required 4 consecutive days or more).
- A second condition constituting an other specified bipolar and related disorder variant is that too few symptoms of hypomania are present to meet criteria for the full bipolar II syndrome, although the duration, at least 4 consecutive days, is sufficient.
- Finally, in both this chapter and in the chapter Depressive Disorders,” an anxious distress specifier is delineated.
