Euthymia

Euthymia describes a mood that is moderate and stable- it is not depressed or manic. It is sometimes used to describe a feeling of tranquility or general pleasantness. Euthymia is typically used when referencing the mood of a patient with bipolar disorder. This type of mood is moderate and does not exhibit marked symptoms of mania or depression. Euthymia is in the middle of the mood spectrum in contrast to hyperthymia (which is an extremely joyful mood characterized by being excessively positive) and dysthymnia (also known as chronic depression or persistant depressive disorder.)
