What are the specific causes of depression?

　　Although we all know that if a long time to live plus work in an environment of excessive pressure, not able to release their own pressure in a timely manner, there is a high probability of suffering from depression this disease, but we are for this disease itself and the onset of symptoms is not particularly understand, so it is difficult to be able to find in a timely manner, in order to avoid this situation, to help patients to find out as soon as possible, we are here today to describe in detail the Depression this disease.

　　 Pathogenesis.

　　So far, the etiology and pathogenesis of depression are not clear, and there are no obvious signs and laboratory indicators of abnormality, summarized as the result of the interaction of biological, psychological and social (cultural) factors. It is also because the cause of depression is unknown, there are many hypotheses, the more commonly recognized etiological assumptions include:

　　 (1) Genetic factors:

　　A large sample of population genetic epidemiologic survey shows that the closer the blood relationship with the diseased person, the higher the probability of disease. The probability of first-degree relatives having the disease is much higher than that of other relatives, which is consistent with the general pattern of genetic diseases.

　　 (2) Biochemical factors:

　　Catecholamine hypothesis: mainly refers to the occurrence of depression may be related to the decrease in the concentration of neurotransmitters 5-hydroxytryptamine (5-HT) and norepinephrine (NE) in the synaptic gap of the brain; due to the fact that after the use of many antidepressants, such as selective 5-hydroxytryptamine reuptake inhibitors (SSRIs) or selective 5-hydroxytryptamine and norepinephrine reuptake inhibitors (SNRIs), etc., though the brain synapse gap concentrations of these neurotransmitters rise quickly, but the antidepressant effect still generally takes about 2 weeks to take effect, thus the hypothesis of increased 5-HT and NE receptor sensitivity (hypersensitivity); and

　　 (3) Psycho-social factors:

　　Various major life events occurring suddenly, or persisting for a long time can cause intense or (and) persistent unpleasant emotional experiences, leading to depression.

　　 Patients should also pay attention to their diet

　　1, patients should choose high protein food in their diet: because protein amino acids are the raw materials for the body to make mood hormones, such as tryptophan can constitute dopamine and melatonin, bananas, dairy products, turkey meat, etc. are foods containing tryptophan.

　　2, patients in the diet should choose to have a certain fat food: ordinary excessive cholesterol is the risk factor of cardiovascular disease and stroke, but if the cholesterol concentration in the food is too low is also depression and chronic fatigue syndrome, or even one of the causes of mental anomalies. So depression patients can consume more fish oil, can improve depression and anxiety, vegetable oil contains a lot of propyl linoleic acid, effective in the treatment of depression.

　　3, patients in and into the diet can choose to rich in vitamins and minerals of food: let's say a certain age of women like effective to avoid the onset of menopausal depression, then it is best is in the young do not lack of vitamins and minerals intake. There is no harm in eating more bananas (a super source of vitamin B6), grapes (high in vitamin C), spinach (with the body's required folic acid), pumpkin (rich in vitamin B6 and iron) and selenium rich sources - chicken, seafood, whole grains and so on.

　　4, patients in the diet can choose polysaccharide food: like common whole grain rice, barley, wheat, oats, melons and high fiber polysaccharide containing vegetables, fruits and so on. These foods by elevating a dopamine substance in the brain to relieve stress and improve mood. However, many refined foods are not suitable because they lack polysaccharides and are dominated by monosaccharides.

　　For patients suffering from depression in daily life in addition to actively cooperate with the doctor for treatment, listen to the doctor's orders in a timely manner with medication, do a good job of their own psychological care program, diet in daily life is also very important, a good diet can help patients to play a role in assisting in the treatment of the role of the patient, so the patient should be to eat more high-protein foods, supplement enough fat, intake of the body's need for sufficient vitamins, minerals and sugars.
