In a way, depression is a “self-limiting illness”, just like a cold, it will get better without treatment. So, is it true that depression can be cured by itself? In response to this question, there are foreign studies and statistics, if depression is not treated, the result will be: 30% (lighter cases) will return to normal naturally, taking about 6-12 months (that is, the “natural course” of depression). 30% will be repeated, dragged into chronic, Lin Daiyu is actually chronic depression, depression The remaining 30% (the more severe cases) will take a desperate path, such as Zhang Guorong, Mitsuru and other well-known figures, and take the road to suicide. Treatments such as medication can change the symptom expression, and the effect can be seen in about 1 month’s time, and the patient will no longer be depressed. But these treatments cannot change the natural course of depression, in other words, we have to wait for it to mend itself; if we stop the medication too early, it will rekindle and depression will appear again. Therefore, it is clinically advocated that patients with depression should take medication for at least 6 months. And generally speaking, 50% of the patients will not have another episode in their lifetime after the depression is cured, that is to say, 50% of the patients will have only one episode in their lifetime, and that is the “root”.
