Physiologic Causes of Depressive Illness

　　At present, more people will appear depression, during the onset of the disease will bring patients particularly disturbed, harming their health, we need to trigger the emergence of the causes of depression to pay attention to, but also should pay attention to their own state of mind, to see what the physiological causes of depression, look down to learn about it.

　　 The causes of depression:

　　Physical disease: a person is very easy to suffer from some physical disease in life, but like stroke, heart attack, cancer, chronic pain, diabetes, hormone disorders and advanced disease these physical diseases may incur depression. There is apathy or inability to deal with one's physical needs, which may be a mood response or objective reaction to a physical illness, or may be a precursor to depression. Personality factors, which is one of the main causes of depression, such as life in the sensitive, suspicious, mood instability, strong, pessimistic, low self-confidence, have a bad form of thought, excessive chagrin or feel simply can not control the life of things and other personalities, are prone to depression, some of the personality.

　　Biochemical factors: When a person suffers from depression, there is often a gradual decrease in the number of chemicals called neurotransmitters in the brain. If there is an imbalance between the two neurotransmitters, 5-hydroxytryptophan and norepinephrine, this can lead to depression or anxiety. 5-hydroxytryptophan and norepinephrine decreases often lead to low mood, decreased motivation, and changes in appetite and sex drive. Biological rhythm changes, we are living in some physiological function indicators such as body temperature, sleep, cortisol and other endocrine have biological circadian rhythm changes is on behalf of a person's affective neurological presentations of disorders, the main manifestation of phase shift, mostly phase forward, that is, the peak of the physiological rhythm of the time earlier, the patient's eyes in depression fast-acting sleep ambient period is shortened (i.e., forward), some people think that can be regarded as the depression of the biological indicators with conclusive significance.

　　Excessive pressure is the cause of the formation of depression: work pressure, life pressure is too heavy will lead to frustration, depression, helplessness, self-blame and many other negative emotions appear, is a common cause of depression. Learning to divide a big event into several small events according to certain ideas, and then gradually carry out with focus, this attitude and method of life and work can not only effectively relieve their own pressure, but also to achieve twice the result with half the effort. Major mental stimulation is the cause of depression, major mental stimulation is a major cause of major depression, common such as the loss of a loved one; couples separated or divorced, unable to face the loss of work, suddenly retired, etc., once you feel that the loss of some very important things, and can not face up to the heart, and the loss of emotion can not be timely dissolution, it may trigger depression.

　　Stress is the cause of depression: the body in a variety of internal and external environmental factors and social and psychological factors stimulate the emergence of systemic non-specific adaptive response, known as stress. The sudden occurrence or long-term persistence of various major life events can cause strong or persistent unpleasant emotional experiences, leading to depression. Genetic susceptibility is responsible for the development of depression, and genetic epidemiologic surveys of large samples of the population have shown that the closer the blood relationship to the person with the disease, the higher the probability of developing depression. 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 disorders, and therefore it can be concluded that genetic factors are at least a risk factor for depression.

　　We read these contents, especially clear understanding of the factors that can trigger the emergence of depression is what, visible causes of this disease is extremely complex, but also to the patient's physical and mental aspects of the harm brought about by the quite serious, friends should be vigilant about the emergence of depression, correctly understand the onset of the factors mentioned above to be able to.
