Two or more factors can have an effect simultaneously to cause depression. Depression can be an independent disease, or a part of other disease. Depression is also divided into different subtypes according to cause.
1. Reactive depression
This disease is simply a result from psychological stress, physical struggle or mental straining without proper rest or sleep over a long time period. The straining will simply wear out the nervous system or deplete the organism from nutrient necessary for the nervous system to work properly.
2. Endogenous depression
When there has not been any period of stress, straining or lack of rest that can explain the condition, the condition is often called endogenous depression. Inheritance is thought to be a part of the cause.
3. Depression by physical disease
Depression or depressive symptoms may be a symptom of physical disease. This is perhaps the most common cause of depression. Generally there are three categories of diseases that give depression:
Diseases often associated with depression are: Heart disease, Parkinson’s disease, stroke, hypertension or Cushing’s syndrome.
Mononucleosis or flu may trigger depression that continues after the infection has gone.
By lack of thyroid hormones, hypothyroidism, the metabolism in the whole body is slowed down, including the production of neurotransmitters in the brain. Therefore depression is an important symptom of hypothyroidism.
4. Depressive symptoms as a consequence of unsound lifestyle
A general unsound lifestyle with too less exercise, too much of stimulants like alcohol, coffee or tea, too less of important nutrient and too much of sugar and fat may give depressive symptoms, as well as physical problems.
5. Postnatal depression
Women will often have a period of depression after pregnancy and berth of the baby Pregnancy and berth is physically and mentally exhausting, and may drain the body for nutrient. This in turn can cause depressive symptoms
.
6. Seasonal affective disorder
Depression can occur in cold and dark periods of the year and go away in warm and light periods. Light stimulates brain activity, and lack of light is a causative factor.
