Mood disorders refer to conditions involving maladaptive expression of any of three basic emotions—sadness, happiness, and anger—and their corresponding thoughts and actions. These three emotions are usually considered to be naturally adaptive reactions to changes that involve loss, gain, or obstruction, respectively. Adaptive reactions to such changes are associated with an eventual return to a euthymic (neutral or somewhat positive) mood state.
