Depression has become the most widespread psychiatric disorder, and patients with severe depression may even be suicidal, far outnumbering other psychiatric disorders in terms of prevalence. The main reason for the wide incidence of depression is its extremely low consultation rate and the characteristics of easy recurrence, of which the proportion of recurrence accounts for about 90% or more, so it seems that depression patients are not cured for a long time is not difficult to understand, why depression always recurring? The reasons are summarized as follows: 1, the patient’s own factors caused by: their own regulatory function ability to decline, they can not effectively block the invasion of external interference factors, but will aggravate the mental abnormalities, this situation is mostly seen in patients who have been repeatedly treated, the condition is not obvious remission; patients although after the drug system treatment, not after the consolidation period of treatment, the condition is not completely recovered when the drug is discontinued, resulting in the disease After recovery, patients who are still dissatisfied with their work and living conditions cannot accept the reality, and the living environment has unfavorable factors for his mental and physical recovery; relapse is also related to physical constitution. Generally speaking, after depression is cured, if the patient’s constitution is still liver-depressed, heart-spleen two deficiency, liver-kidney yin deficiency, it is easy to lead to depression under the stimulation of emotion. 2, emotional stimulation: the invasion of external evil, resulting in emotional abnormalities, which is the basic condition of the disease: from the perspective of traditional Chinese medicine, the recurrence of depression is closely related to the emotional, so after the cure of depression can not be because the disease has been cured, we must avoid emotional stimulation, maintain the stability of life, the environment, try to avoid conflict with others, such as the occurrence of conflict must have a correct treatment, while family members The family should have an overall arrangement for the patient’s study, work and living environment, so that they can be aware of the situation and prevent excessive stress and mental stimulation. Since everything is starting from scratch, we have to take our time and let the patient gradually adapt to the new work and living environment, not to be rushed. 3, seasonal factors caused by relapse should not be ignored: another factor closely related to the relapse of depression is the change of seasons. According to Chinese medicine, the weather has a certain influence on specific diseases and physique. Generally, in autumn and winter, when the seasons change, especially when the weather changes abnormally or suddenly, depression is prone to recurrence, and this is the reason for the saying “autumn sorrow”, which also reflects the understanding of Chinese medicine theory about autumn gold slaughter, depression is prone to attack in autumn and winter. 4, the treatment of a single: simple medication is only able to remove the symptoms, if not for the root cause of depression treatment, depression is easy to relapse. Therefore, simply controlling the symptoms cannot fundamentally solve the root cause of depression. To always keep an optimistic and positive mind is the key to prevent and cooperate with the treatment of depression, think in the good and simple direction, and believe that you can overcome the long-standing depression.
