Definition (psychiatry)
In psychiatry a maniac is a person who suffers the mental disease called mania. This type of personality shows an emotionally expansive behaviour, hyperirritability, excess of loquacity, hyperkinesis (hyperactivity and inability to pay attention), and an excessive imagination. --http://en.wikipedia.org/wiki/Maniac [Apr 2005]
Mania is a medical condition characterised by severely elevated mood. Mania is most usually associated with bipolar disorder, where episodes of mania may cyclically alternate with episodes of depression. (Note: not all mania can be classified as bipolar disorder, as mania may result from other diseases or causes. However, bipolar disorder is the "classic" manic disease.) Hypomania is a less severe variant of mania, where there is less loss of control. --http://en.wikipedia.org/wiki/Mania [Aug 2006]
