Cyclothymic Disorder

Cyclothymia

The Facts

Cyclothymic disorder, also called cyclothymia, is a type of mood disorder where people experience numerous periods of mood "highs" and "lows" that are unrelated to life circumstances. The mood instability - mild elation or mild depression - is related to bipolar disorder (formerly known as manic depression) and is in fact considered to be a milder form of bipolar disorder.

Though less severe, cyclothymia can have great impact on a person's life, where unexpected and extreme mood changes disrupt the ability to function normally.

Both men and women are equally likely to suffer from cyclothymia, affecting up to 1% of the population. Cyclothymic disorder generally starts appearing during young adulthood, though it may also first occur at a later age.

Causes

The exact causes of cyclothymia are not known, but it is often a result of the same genetic factors that cause bipolar disorder. In fact, there is an estimated 15% to 50% risk that people with cyclothymia will eventually be diagnosed with bipolar disorder following a full-blown manic episode or major depression.

People with cyclothymic disorder usually have a family history of major depression, bipolar disorder, suicide, or alcohol or drug dependence.
