Mania and Hypomania
Add to Criterion A: “and abnormally and persistently increased activity or energy”
Increased activity or energy became a core symptom Increased activity or energy became a core symptom of mania hypomania.
Rationale: this will make explicit the requirement of increased
energy/activity in order to diagnose bipolar I or II disorder (which is not required under DSM-IV) and will improve the specificity of the diagnosis.

Mania and Hypomania:
“Antidepressant switching”
A full manic/hypomanic episode that emergesduring antidepressant treatment (e.g., medication,during antidepressant treatment (e.g., medication,electroconvulsive therapy) but persists at a fullysyndromal level beyond the physiological effectof that treatment is now sufficient evidence for amanic/hypomanic episode and, therefore, abipolar diagnosis.

No more “Mixed episode”
“Mixed episode” is replaced with a “with mixed features” specifier for manic, hypomanic, and features” specifier for manic, hypomanic, and major depressive episodes (> 3 symptoms from other pole).
– Rationale: DSM-IV criteria excluded from diagnosis the
sizeable population of individuals with subthreshold mixed states who did not meet full criteria for major depression and mania, and thus were less likely to receive treatment.

“With anxious distress” also added as a specifier for bipolar (and depressive) disorders
– Rationale: the co-occurrence of anxiety with – Rationale: the co-occurrence of anxiety with depression is one of the most commonly seen comorbidities in clinical populations. Addition of this specifier will allow clinicians to indicate the presence of anxiety symptoms that are not reflected in the core criteria for depression and mania but nonetheless may be meaningful for treatment planning.

Antidepressant monotherapy should be avoided in bipolar disorder.
Adjunctive antidepressants may be used for an acute bipolar depression when there is a history of previous positive response to antidepressants. And patient should be closely monitored for to antidepressants.
