　　(2) 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 generally takes about 2 weeks to take effect, so there is another hypothesis of increased sensitivity of 5-HT and NE receptors (hypersensitivity);.
