Manual of Mental Disorders classification system where a disturbance in the
person's mood is hypothesized to be the main underlying feature.^[1] The

Mood disorders fall into the basic groups of elevated mood such as mania or
hypomania, depressed mood of which the best-known and most researched is
major depressive disorder (MDD) (commonly called clinical depression,
unipolar depression, or major depression), and moods which cycle between
mania and depression known as bipolar disorder (BD) (formerly known as
manic depression). There are several sub-types of depressive disorders or
psychiatric syndromes featuring less severe symptoms such as dysthymic
disorder (similar to but milder than MDD) and cyclothymic disorder (similar
to but milder than BD).^[4]^[/page needed/] Mood disorders may also be
substance-induced or occur in response to a medical condition.
