Hypomania

Hypomania is a less severe form of mania, which is not usually followed by a major depressive episode. Symptoms may include increased energy, grandiose (absurd exaggeration) thoughts decreased need for sleep, overindulgence in inappropriate and risky behaviors such as sexual encounters and unnecessary spending. Mood is elevated. The individual will experience irritability and racing thoughts.

Some people have very few manic-depressive episodes, with years of stability in between them. They may experience no more than a couple of episodes in their whole lifetime. Others have many more frequent cycles – 'rapid cycling' means having four or more episodes a year. About one per cent of the general population is diagnosed with manic depression – a roughly equal number of men and women – usually in their 20s or 30s (although some teenagers are affected). They are often intelligent and creative people.
