Cerebral insufficiency can be divided into acute cerebral insufficiency and chronic cerebral insufficiency, and the treatment methods are different for different cases. Acute cerebral insufficiency refers to transient cerebral ischemic attack, which should be treated comprehensively when it occurs. On the one hand, risk factors should be controlled, mainly including smoking cessation, alcohol cessation, control of hypertension, hyperglycemia and hyperlipidemia, etc. On the other hand, treatment of cerebral ischemia should be started, which can include oral aspirin or clopidogrel, statins, improvement of microcirculation (such as Ginkgo biloba extract tablets, nimodipine, etc.) and vasodilators (vincristine, etc.) Drugs. Chronic cerebral hypoperfusion is usually treated according to the cause, most commonly caused by cerebral atherosclerosis in the elderly, which is a normal and irreversible phenomenon, and on the one hand, we can improve the symptoms by taking oral circulatory and vasodilator drugs, and on the other hand, we can slow down the progress of the disease by controlling risk factors and improving lifestyles. In addition, when atherosclerotic plaque formation causes severe narrowing of the arteries, thus causing cerebral blood supply deficiency, it can be treated by implanting stents. In conclusion, there are many causes of cerebral insufficiency, which should be treated symptomatically after consultation with neurology.
