What factors can trigger depression?

　　With our life is now getting better and better, however, people's mental stress is also more and more, which led to more and more patients with depression, to our normal life has brought a certain degree of distress, many patients often appear dizziness and brain swelling and other symptoms, the following we will look specifically at what factors induced depression?

　 　(1) genetic factors:

　　After analyzing the relevant data many depression patients were found to have genetic factors exist. A large sample of the 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 of the disease is much higher than that of other relatives, which is consistent with the general law of genetic diseases.

　 　(2) Psycho-social factors:

　　We know that depression is a psychological mood disorder, so depression is largely related to psychological and social factors, a variety of major life events that occur suddenly or persist for a long period of time can cause strong or (and) persistent unpleasant emotional experience leading to depression.

　 　(3) Biochemical factors:

　　This biochemical factor is also an important and invisible factor that causes depression in people with depression. Mainly refers to the occurrence of depression may be related to the brain synaptic gap neurotransmitter -hydroxytryptamine (-HT) and norepinephrine (NE) concentration decline; due to the use of many antidepressants such as selective -hydroxytryptamine reuptake inhibitors (SSRI) or selective -hydroxytryptamine and norepinephrine reuptake inhibitors (SNRI), etc. Although the brain synaptic gap concentration of these neurotransmitters quickly Although the concentration of these neurotransmitters in the synaptic space of the brain rises very quickly after use, the antidepressant effect usually takes about a week to take effect, so there is the hypothesis of increased sensitivity of -HT and NE receptors (hypersensitivity).

　　The points introduced above are the triggering factors of depression, I hope to be able to bring you some help, I believe we have more understanding, then we should try to avoid the occurrence of these factors in life, to kill depression in the invisible, but also hope that patients with depression can be recovered soon.
