Mood swing

A mood swing is an extreme or rapid change in mood. Such mood swings can play a positive part in promoting problem solving and in producing flexible forward planning. However, when mood swings are so strong that they are disruptive, they may be the main part of a bipolar disorder. Mood swings can happen any time at any place, varying from the microscopic to the wild oscillations of manic depression, so that a continuum can be traced from normal struggles around self-esteem, through cyclothymia, up to a depressive disease. However most people's mood swings remain in the mild to moderate range of emotional ups and downs. The duration of mood swings also varies. They may last a few hours - ultrarapid - or extend over days - ultradian: clinicians maintain that only when four continuous days of hypomania, or seven days of mania, occur, is a diagnosis of bipolar disorder justified. In such cases, mood swings can extend over several days, even weeks: these episodes may consist of rapid alternation between feelings of depression and euphoria. Changes in a person's energy level, sleep patterns, self-esteem, concentration, drug or alcohol use can be signs of an oncoming mood disorder.
