As far as the current medical condition is concerned, cerebral insufficiency can be cured. The main symptoms of cerebral insufficiency are dizziness, blurred vision and unsteadiness. If these symptoms occur, a clear diagnosis is needed to exclude other disorders that can cause dizziness. Once the diagnosis of cerebral insufficiency is confirmed, active treatment is needed to avoid aggravating the condition and leading to other more serious consequences. Treatment often differs for patients of different ages and with different underlying diseases. If the patient is young and does not have underlying diseases such as hypertension, diabetes, hyperlipidemia, etc., but only has cerebral insufficiency due to cervical spondylosis, different treatments can be given depending on the severity of the condition. If the condition is mild, the symptoms of cerebral hypoperfusion can be improved without medication, and the patient should be instructed to avoid prolonged head bowing and desk ambulation and to protect the cervical spine; if the condition is severe, with nausea and vomiting and inability to open the eyes, intravenous medication is required, such as improving microcirculation, acid suppression and stomach protection, and even sedation with promethazine. In the case of men over 50 years old, or women over 55 years old, with any of the combination of hypertension, diabetes, hyperlipidemia, carotid atherosclerosis, etc., they need to actively initiate primary prevention, improve their diet, promote a low salt, low fat, low sugar diet, avoid excessive intake of animal fat and carbohydrates, and eat more fruits and vegetables and green leafy vegetables. If there is narrowing of the blood vessels in the head and neck area or even occlusion is found through examination, secondary prevention needs to be started immediately by routinely taking oral anti-atherosclerosis, anti-platelet aggregation and microcirculation improvement drugs. Blood pressure management and blood glucose regulation are also needed. If the stenosis reaches 75% or more and there is severe dizziness and inability to walk, which seriously affects daily life and work, then stent implantation is recommended if necessary.
