Mania: An abnormally elevated mood state characterized by such symptoms as inappropriate elation, increased irritability, severe insomnia, grandiose notions, increased speed and/or volume of speech, disconnected and racing thoughts, increased sexual desire, markedly increased energy and activity level, poor judgment, and inappropriate social behavior. A mild form in mania that does not require hospitalization is termed hypomania. Mania that also features symptoms of depression ("agitated depression") is called mixed mania.
Mania is the Greek word for madness. It is derived from mainmai, to rave in anger. The Maniai in Greek mythology were the Furies who pursued those who had done unavenged crimes and drove them to madness.
