What are the causes of depression?

核心提示: 遗传因素：大样本人群遗传流行病学调查显示，与患病者血缘关系愈近，患病概率越高。 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.

　　Experts say depression belongs to a kind of mental illness, the occurrence of the disease to the patient's health, so what causes depression? Experts say that the cause of the disease can not do an accurate measurement and description, but often clinical observation found with psychological factors, genetic factors and biochemical factors have a certain relationship, the specific content of the following for you in detail.

　　⒈ psychological factors: a variety of major life events occur suddenly, or long-term persistence will cause strong or (and) lasting unpleasant emotional experience, leading to depression.

　　⒉Genetic factors: a large sample of population genetic epidemiological survey shows that the closer the blood relationship with the patient, the higher the probability of illness. The probability of first-degree relatives suffering from the disease is much higher than other relatives, which is consistent with the general law of genetic diseases.

　　Biochemical factors: catecholamine hypothesis: mainly refers to the occurrence of depression may be related to the brain synaptic gap neurotransmitter 5-hydroxytryptamine (5-HT) and norepinephrine (NE) concentration decline; due to the use of many antidepressants, such as selective 5-hydroxytryptamine reuptake inhibitors (SSRI) or selective 5-hydroxytryptamine and norepinephrine reuptake inhibitors (SNRI) and so on. Although the concentration of these neurotransmitters in the synaptic gap of the brain rises quickly, the antidepressant effect still generally takes about 2 weeks to take effect, hence the additional hypothesis of increased sensitivity (hypersensitivity) of 5-HT and NE receptors.

　　The above is the cause of depression, I believe that we have been clear, experts say that depression is not terrible, terrible is the patient is not actively cooperate with the doctor's treatment, so that the patient's family members should be more accompanied by them, more patience and more confidence, to help the patient out of the haze of the disease.
