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.
Bipolar disorder is in a class of mood disorders that is marked by dramatic changes in mood, energy and behaviour. The key characteristic of people with bipolar disorder is alternating between episodes of mania (extreme elevated mood) and depression (extreme sadness). These episodes can last from hours to months. The mood disturbances are severe enough to affect the personâs ability to function.
