The concept of “cerebral nerve disorder” does not exist in clinical practice. Cerebral nerve disorder generally refers to the disorder of vegetative nerve function, which is a kind of disease caused by the patient’s prolonged mental tension, excessive psychological pressure and mental stimulation. At the onset of the disease, patients will have mental symptoms, intellectual decline and physical symptoms. 1. Mental symptoms: the patient will have a state of anxiety and depression, such as not being interested in anything, being distressed and depressed, and feeling that there is no point in living. 2. Intelligence decline: manifested as inattention, slow reaction, memory loss and so on. 3. Physical symptoms: patients may have tasteless eating, bloating, nausea, acid reflux, heartburn, etc., which may also be accompanied by chest tightness, shortness of breath, panic, body stiffness and discomfort, numbness of limbs, warmth of hands and feet, and other symptoms. Patients with phytoneurological dysfunction should adjust their daily life style, go to bed early and get up early, and self-regulate their emotions to improve their symptoms. Patients can also follow the doctor’s instructions to take oral glutamine, vitamin B₁ and other drugs to adjust the nerve function. Patients with excessive psychological stress should go to the psychological outpatient clinic of the hospital and be treated through psychological counseling.
