Major Depressive Disorders

Major Depressive Disorders

Major depressive disorder is also referred to as major, biochemical, clinical, endogenous, or biological depression. It may also be called unipolar affective disorder.

There are many subtypes of depression:

Melancholia, or melancholic depression, is very severe (bad). It can cause many physical changes, like sleep and appetite changes. It can also cause a person to change their behavior - for example, by not wanting to be around other people.

Psychotic depression is much like melancholia, but with hallucinations or delusions.

Atypical depression causes anxiety and panic attacks.

Chronic dysthymic disorder is a long-term, mild depression that lasts for at least two years. It often begins in adolescence and lasts for many years.

Seasonal affective disorder (SAD) is when the depression seems to be related to the winter season. It usually starts in the autumn and goes away in the spring every year. It is common in Alaska, Canada, and Scandinavia (Sweden, Norway, Denmark, and Finland), but not in Iceland (Wikipedia, 2018).
