Cyclothymia is a mood and mental disorder in the bipolar spectrum that causes both hypomanic and depressive episodes. It is defined medically within the bipolar spectrum and consists of recurrent disturbances between sudden hypomania and dysthymic episodes. The diagnosis of cyclothymic disorder is not made when there is a history of mania or major depressive episode or mixed episode. The lifetime prevalence of cyclothymic disorder is 0.4-1%. The rate appears equal in men and women, though women more often seek treatment. Unlike some other forms of bipolar disorder (to be specific, bipolar I disorder), people with cyclothymia are more often either somewhat or fully functioning^{[citation needed]}, sometimes even hyper-productive.

Cyclothymia is similar to bipolar II disorder in that it presents itself in signature hypomanic episodes. Because hypomania is often associated with exceptionally creative, outgoing, and high-functioning behavior, both conditions are often undiagnosed. As with most of the disorders in the bipolar spectrum, it is the depressive phase that leads most sufferers to get help. The term derives from the Greek κύκλος (kuklos), "circle" + θυμός (thumos), "temper".

Differential diagnosis

This disorder is common in the relatives of patients with bipolar disorder, and some individuals with cyclothymia eventually develop bipolar disorder themselves. It may persist throughout adult life, cease temporarily or permanently, or develop into more severe mood swings, meeting the criteria for bipolar disorder or recurrent depressive disorder in rare cases.

Symptoms

Dysthymic phase

Symptoms of the dysthymic phase include difficulty making decisions, problems concentrating, poor memory recall, guilt, self-criticism, low self-esteem, pessimism, self-destructive thinking, continuously feeling sad, apathy, hopelessness, helplessness, irritability, quick temper, poor judgment, lack of motivation, social withdrawal, appetite change, lack of sexual desire, self-neglect, fatigue, and insomnia.

Euphoric phase

Symptoms of the euphoric phase include unusually good mood or cheerfulness (euphoria), extreme optimism, inflated self-esteem, rapid speech, racing thoughts, aggressive or hostile behavior, being inconsiderate of others, agitation, massively increased physical activity, risky behavior, spending sprees, increased drive to perform or achieve goals, increased sexual drive, decreased need for sleep, tendency to be easily distracted, and inability to concentrate.

Causes

There may be a genetic component to Cyclothymia. In one study, it was found that an individual is 2-3 times more likely to have the disorder if an identical twin is affected.
