Cerebral blood supply insufficiency is a nervous system disease. It is suggested that patients should go to the neurology department in time after the clinical manifestation of cerebral blood supply insufficiency. In case of acute attack, it is suggested that the patient should go to the emergency department, combine the clinical manifestations of the patient, and improve the corresponding auxiliary examinations, such as brain CT, brain MRI, to make a clear diagnosis and carry out intervention treatment. Cerebral blood supply insufficiency is more common in middle-aged and elderly people. Patients often have hypertension, diabetes, hyperlipidemia, or bad life habits such as smoking and drinking. With the existence of the above risk factors, the vertebrobasilar artery system of the patient gradually narrows or even occludes, resulting in clinical symptoms of the patient. After the onset of the disease, even after the remission of the disease in the future, the patient also needs to take oral medicine on time according to the doctor's advice, and also needs to control the basic diseases, develop a good life rule, and take regular outpatient reexamination.
