Definition    Return to top

Cyclothymic disorder is a mild form of bipolar disorder in which a person has mood swings from mild or moderate depression to euphoria and excitement, but stays connected to reality.

Causes    Return to top

The cause of cyclothymic disorder is unknown. Although the changes in mood are irregular and quick, the mood swings are far less severe than in bipolar disorder (manic depressive illness). Unlike in bipolar disorder, periods of hypomania often do not become actual mania.

Exams and Tests    Return to top

The person's own description of the behavior usually leads to diagnosis of the disorder.

Treatment    Return to top

A combination of antimanic drugs, antidepressants, or psychotherapy are used to treat cyclothymic disorder. Medications used to treat this condition are called mood stabilizers.

Patients may not respond to medications as strongly as do patients with bipolar disorder.

Support Groups    Return to top

You can ease the stress of illness by joining a support group whose members share common experiences and problems.

Outlook (Prognosis)    Return to top

Most people do not need long-term therapy.

Cyclothymic disorder may lead to full-blown bipolar disorder in some people, or it may continue as a chronic condition.

Possible Complications    Return to top

The condition can progress to bipolar disorder.
