What causes depression?

　　I believe that we have some knowledge of the disease of depression, which is a very terrible mental illness, bringing very serious mental disorders to the patient, and therefore plagued the patient's life, friends should be careful to guard against the emergence of depression, but also a clear understanding of the causes of this disease, in the end, what are the factors that triggered the depression it.

　　First, the environmental triggers: such as in the life of some stressful life events and loss may lead to a person suffering from depression, such as widowhood (especially the elderly widowed, almost 80%, 90% of the people will get this disease), divorce, loss of work, loss of health, financial crises and so on. Disease factors, commonly found in patients with diabetes, heart disease, stroke and cancer, are prone to depression. Like hyperthyroidism, even in mild cases, you can suffer from depression. Depression can also be a precursor to serious illnesses like Parkinson's disease, pancreatic cancer, brain tumors, Alzheimer's disease, etc.

　　Secondly, genetic inheritance: common assumption is that if there is a history of depression in a person's family, then their likelihood of suffering from depression is much higher than that of a normal person. Research shows that one of the parents have depression, children have a 25% chance of getting the disease; if both parents are patients with depression, children's prevalence rate of progress to 50% to 75%. Environmental triggers, such as in the life of some people feel stressed about life things and the sense of loss may lead to a person suffering from depression, such as widowhood (especially the elderly widowed, simply eight, 90% of people will get this disease), divorce, loss of work, financial crisis, loss of health. Drugs, if a person has been taking high blood pressure medication, arthritis or Parkinson's medication for a long period of time, then it greatly increases the risk of depression.

　　Third, family heredity. Researchers have found that if there are patients with depression in the family, then the risk of other family members will increase, which may be genetic predisposition to depression, including bipolar depression, which is a higher heritability, which is a cause of depression. Socio-environmental factors, interpersonal communication, work pressure, family conflicts and other such psychosocial factors may lead to the occurrence of depression. In addition, some serious physical illnesses, such as stroke, heart attack, hormonal disorders, etc. often trigger depression, and make the original disease worse. In addition, 1/3 of depressed people have substance abuse problems.

　　Fourth, disease: such as living with heart disease, stroke, diabetes, cancer and Alzheimer's disease of these chronic diseases, once the disease, patients are more likely to suffer from depression. Hyperthyroidism, even if the condition is subtle, can suffer from sadness. Sadness can also be a precursor to serious illnesses such as pancreatic cancer, brain tumors, Parkinson's disease, and Alzheimer's disease. Individuals, who are at greater risk of suffering from depression, assuming that they have a long history of negative moods such as low self-esteem, self-blame, and pessimism in their lives. Smoking, alcohol and drug abuse, before a lot of people feel that they can use alcohol and nicotine to soothe the mood of depression. But in fact, the use of these things can actually trigger sadness and anxiety. Diet, if a person's rituals are deficient in folic acid and vitamin B12, may also cause sadness.

　　By recognizing the knowledge in the above, we understand the factors related to the onset of depression, depression affects the patient's usual life, and will make them appear very serious mental disorders, so we have to know more about depression, but also to avoid the causes of this disease can be.
