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.
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.

- Alternating episodes of hypomania and mild depression lasting for at least 2 years
- Patients tend to be more irritable or dark, rather than euphoric or happy
- Persistent symptoms (less than 2 symptom-free months in a row)
The person's own description of the behavior usually leads to diagnosis of the disorder.
You can ease the stress of illness by joining a support group whose members share common experiences and problems.
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.
Call a mental health professional if you or your child has persistent alternating periods of depression and excitement that negatively affect your work or social life.
The condition can progress to bipolar disorder.
A combination of antimanic drugs, antidepressants, or psychotherapy are used to treat cyclothymic disorder. Medications used to treat this condition are called mood stabilizers.
Lithium. Lithium has been used for years in patients with bipolar disorder, and it may also help patients with cyclothymic disorder.
Antiseizure drugs. Valproic acid (Valproate), carbamazepine (Tegretol), oxcarbazepine (Trileptal), and lamotrigine (Lamictal) are the most established antiseizure drugs. Other antiseizure drugs used for bipolar disorders include gabapentin (Neurontin), zonisamide (Zonegran), and topiramate (Topamax).
Patients may not respond to medications as strongly as do patients with bipolar disorder.
