Types of depression
Depression is often divided into subtypes according to exhibited symptoms.
1. Mono-polar depression and dysthymic disorder
By mono-polar depression there are pure depressive symptoms. Mild cases of mono-polar disorder that do not affect a persons ability to work and to participate in social activities are often called dysthymic disorder.
2. Bipolar disorder (manic-depressive disease) and cyclothymic disorder
In this condition there are periods with symptoms of depression - the depressive phase, alternating with periods of elevated mood level with increased mental and physical activity - the manic phase. In the manic phase, the affected person also sleeps poorly and has concentration difficulties. A mild form of this disease is called cyclothymic disorder.
3. Manic disorder
This condition is characterized by abnormally elevated mood, by unrealistic optimism, by lack of sleep and by hyperactive behaviour. Many psychiatrists think that this disorder is simply the same disease as bipolar disorder where the depressive face has not yet occurred.
4. Depression with mainly physical symptoms
Sometimes the physical symptoms of depression are alone or dominant, as for example: Digestive problems, constipation, difficulties with urination, slow response to sensorial stimuli or slow physical reactions.
Clinical depression
Clinical depression is also known as major depression, unipolar depression, and major depressive disorder. People who experience clinical depression feel persistently sad. There are three main types of depression; unipolar disorder (major depression), bipolar disorder (manic depression) and dysthymia (prolonged sadness).
