We know that the normal human cerebral cortex has two processes of excitation and inhibition, which can command a person to be in a state of excitement during the day, manifesting as energetic and clear-headed, while being in a state of inhibition at night and sleeping normally. In neurasthenia patients, the excitation and inhibition processes of the brain are disturbed, and they suffer from insomnia at night, while they have no energy during the day, cannot concentrate, and make their learning work efficiency drop. In other words, the brain cannot be excited when it should be excited and cannot be inhibited when it should be inhibited, and the balance between excitation and inhibition processes is out of balance. Neurosis occurs mostly in young adults and is more common in brain workers. Any situation that can cause excessive nervous tension in the brain and accompanied by bad emotions can be the cause of neurasthenia. Unsound character also plays an important role in the onset of the disease. Timid, sensitive, suspicious, introverted, pessimistic people, even general mental stimulation, may also induce neurasthenia. In essence, the so-called neurasthenia is only a mild disorder of brain function activity caused by excessive stress in the cerebral cortex due to psychosocial factors, and the brain itself is not damaged, so it is a psychogenic disease that requires patients to make effective psychological adjustments and build a sound personality. However, many patients adopt various incorrect practices, resulting in their illnesses remaining untreated for a long time. Since the brain of neurasthenia patients does not have any substantial pathology, the name of neurasthenia has disappeared from the list of diseases in many countries and has been replaced by “fatigue syndrome”. Neurosis is a psychosomatic disease, with various physical or mental (psychological) discomfort, strong internal conflicts or unpleasant emotional experiences, which often persist or recur, but in any case there is no organic damage in the brain, so it does not affect intelligence and memory. Individuals with neurasthenia are afraid that they are suffering from psychosis or that they will turn into psychosis in the future. Some people have followed up neurasthenia patients for 5 years and found no cases of psychosis. This shows that there is no need for patients to worry about this, otherwise the worry will add to the worry and make the nerves even more debilitating. The treatment of neurasthenia can not rely on drugs alone, to not rely entirely on sports or labor exercise. The initiative to treat this disease is in the hands of the patient himself, lies in the patient gradually change the personality of the bad tendencies, under the patient of the disease is not afraid, not worried, not to notice. Of course it is not easy to do. Can not imagine in a day, a week, a month this complete recovery. Everything to do the worst consequences of psychological preparation, towards the best direction to strive for. Once the psychological burden is reduced, and then pay attention to the combination of work and rest, and actively participate in fitness activities suitable for themselves, the symptoms of neurasthenia will gradually reduce and even disappear.
