Why do I suffer from depression?

　　A: Genetic factors Depression is associated with heredity, and the offspring of patients have an increased chance of developing the disease. But this does not mean that only parents elders suffering from depression themselves will suffer from this disease, or that their own illness will definitely be inherited to their offspring.

　　Neurobiochemical factors The metabolism of certain neurotransmitters in the brain of patients with depression is abnormal, such as the decrease in the concentration of 5-hydroxytryptamine and norepinephrine, which leads to the overall low state of patients' mental activities and psychological functions.

　　Psychosocial factors Depression is associated with stressful life events (sudden misfortunes in life, such as loss of a job and serious illness) as well as with one's own personality, and stressful life events can be triggering factors for depression.
