Overview
Bipolar II Disorder is a bipolar spectrum disorder that is characterized by at least one hypomanic episode and at least one major depressive episode; with this disorder, depressive episodes are more frequent and more intense than manic episodes. It is believed to be underdiagnosed because hypomanic behavior often presents as high-functioning.[citation needed]
Differential Diagnosis
- Anxiety disorders
- Attention-deficit/hyperactivity disorder
- Cyclothymic disorder
- Major depressive disorder
- Other bipolar disorders
- Panic disorder
- Personality disorders
- Schizophrenia spectrum and other related psychotic disorders
- Substance use disorders[1]
Epidemiology and Demographics
Prevalence
The 12 month prevalence of bipolar II disorder is 800 per 100,000 (0.8%) of the overall population.[1]
Risk Factors
- Genetic predisposition[1]
Natural History,Complications,and Prognosis
Prognosis
Good prognostic factors include:
- More education
- Fewer years of illness
- Married
Poor prognostic factors include:
- Rapid-cycling pattern
Diagnostic Criteria
DSM-V Diagnostic Criteria for Bipolar II Disorder[1]

For a diagnosis of bipolar II disorder, it is necessary to meet the following criteria for a current or past hypomanic episode and the following criteria for a current or past major depressive episode: Hypomanic Episode

episode is, by definition, manic. AND
Note:A full hypomanic episode that emerges during antidepressant treatment (e.g.,medication, electroconvulsive therapy) but persists at a fully syndromal level beyond the physiological effect of that treatment is sufficient evidence for a hypomanic episode diagnosis. However, caution is indicated so that one or two symptoms (particularly increased irritability, edginess, or agitation following antidepressant use) are not taken as sufficient for diagnosis of a hypomanic episode, nor necessarily indicative of a bipolar diathesis. Major Depressive Episode
is either (1 ) depressed mood or (2) loss of interest or pleasure. Note:Do not include symptoms that are clearly attributable to a medical condition.
appears tearful). (Note: In children and adolescents, can be irritable mood.)
day.(Note:In children, consider failure to make expected weight gain.)
AND
AND
Note:Criteria A-C above constitute a major depressive episode. Note:Responses to a significant loss (e.g., bereavement, financial ruin, losses from a natural disaster, a serious medical illness or disability) may include the feelings of intense sadness, rumination about the loss, insomnia, poor appetite, and weight loss noted in Criterion A, which may resemble a depressive episode. Although such symptoms may be understandable or considered appropriate to the loss, the presence of a major depressive episode in addition to the normal response to a significant loss should be carefully considered. This decision inevitably requires the exercise of clinical judgment based on the individual’s history and the cultural norms for the expression of distress in the context of loss.
