Neurasthenia has not been diagnosed in the United States and Western Europe, and the diagnosis of neurasthenia in China has also decreased significantly.

[etiology]

At present, most scholars believe that mental factors are the main cause of neurasthenia. Any factor that can cause persistent tension and long-term internal contradictions makes the process of nerve activity in a strong and persistent state of tension, which exceeds the tolerance limit of nervous system tension and can cause diseases. Such as: 1. Excessive fatigue without rest is excessive tension during excitement; 2. Dissatisfaction with the status quo indicates that the inhibition process is too tense; 3. Often change the living environment and not adapt, so that the central nervous system is in a state of excessive tension and fatigue. Neurons in the cerebral cortex are highly tolerant. After intense mental work, although I am very tired, I can recover after a rest. Once the long-term nervous activity exceeds the tolerance limit, neurasthenia may occur.
