Major Depressive Disorder (MDD)
- Characterized by significant depression and loss of function lasting at least two weeks and not caused by substance use or a general medical condition (such as hypothyroidism). DSM considers symptoms significant if at least five of the following are present:
- -depressed mood most of the time
- -markedly diminished interest or pleasure in most activities most of the time
- -significant weight loss or gain or significant appetite change
- -insomnia or hypersomnia most days
- -psychomotor agitation or retardation most of the time
- -feeling worthless/guilty most of the time
- -diminished thinking/concentration/decisiveness
- -recurring thoughts of death or suicide
For such persons, even though they lack energy and may be sleep deprived, they feel keyed up, restless, and fidgety
characterized by the presence of two affective "poles," depression and mania. The presence of mania, then, is the diagnostic distinction between Bipolar Disorder and Major Depression. Of course, in cases which manifest with depression at first, misdiagnosis is common.
Characterized by chronically depressed mood. These persons usually are not as severely depressed as those with Major Depression, but their symptoms are usually present for years (2 years is the minimum for diagnosis in adults, 1 year in children and adolescents). To appreciate this disorder, imagine that you almost never feel very good, regardless of the reason—you no doubt recognize that life will lack luster, you will often feel beaten down, and general functioning will suffer.

characterized by a relatively chronic condition in which the person struggles to maintain an even mood. The mood is both unstable and rarely neutral. Thus, affected persons are chronically up or down, experiencing mild depression or elevation similar to that of hypomania. Some evidence suggests that these persons are too dependent on external cues for their mood, such that they overreact to perceived good or bad in the environment.
