Patients with severe sleep deprivation are mainly considered to be caused by insomnia. If patients are usually emotionally stressed and anxious, it is easy to trigger patients to have difficulty sleeping and low sleep quality, or it is related to patients’ poor lifestyle, such as often staying up late, or even staying up all night, which can lead to patients being in extreme fatigue of body and brain, and serious sleep deprivation, resulting in patients’ nerves being in disorder and causing abnormalities in brain nerve function. This causes abnormal brain nerve function. Neurasthenia can cause memory loss, as well as dizziness, dullness, lack of concentration, memory loss and other problems. There is also a serious lack of sleep related to the patient’s lifestyle, such as drinking strong tea, strong coffee and other excitatory drinks before bedtime, which can easily lead to difficulties in falling asleep.
