Bipolar II Disorder
A mood disorder defined by at least one hypomanic episode and at least one major depressive episode, without a full manic episode.
Overview
Bipolar II disorder involves at least one hypomanic episode and at least one major depressive episode, without a full manic episode. Depressive episodes are often more prominent and impairing than hypomanic periods.
Signs and Symptoms
Hypomania can involve elevated or irritable mood, increased energy, and decreased need for sleep that is noticeable but less severe than mania. Depressive episodes resemble those in major depressive disorder. Experiencing one or more of these symptoms does not necessarily mean that a person has this condition. Diagnosis requires an appropriate clinical evaluation.
Causes and Risk Factors
The exact cause is not fully understood. Genetic factors and changes in brain function are associated with bipolar II disorder, similar to bipolar I disorder.
Diagnosis
A diagnosis should be made by a qualified healthcare professional following a comprehensive clinical assessment. Clinicians may use established diagnostic frameworks such as DSM-5-TR and/or ICD-11 as part of a comprehensive assessment.
Treatment
Treatment depends on the individual’s symptoms, clinical history, severity, age, co-occurring conditions, and other relevant factors.
Psychotherapy
Psychoeducation and cognitive behavioral or interpersonal therapy may help support mood stability alongside medication.
Medication
Mood stabilizers and certain other medications may be recommended, particularly to manage depressive episodes and prevent recurrence. Medication decisions should be made with a qualified prescribing healthcare professional. Do not start, stop, or change a prescribed medication based solely on information on this page.
Living With Bipolar II Disorder
Consistent sleep, mood tracking, and stress management can help reduce the frequency of mood episodes.
When to Seek Professional Help
Professional evaluation may be appropriate if symptoms persist, worsen, cause significant distress, or interfere with work, school, or relationships.
Emergency Situations
If a person may be in immediate danger, is experiencing a medical or psychiatric emergency, or may harm themselves or another person, seek immediate assistance through appropriate local emergency services.
Outlook
Bipolar II disorder is a chronic condition that can be managed effectively for many people with ongoing treatment.
