The range of cerebral ischemia is broad, including the concepts of acute cerebral infarction, transient ischemic attack and chronic cerebral ischemia, etc. There are many factors affecting cerebral blood supply, and targeted treatment should be carried out according to different causes. 1.Adjustment of blood pressure: both too low and too high blood pressure will affect cerebral perfusion and cause the occurrence of cerebral ischemia; therefore, it is important to control and maintain blood pressure within the normal range so as to terminate and reduce transient ischemic attacks and prevent or postpone the occurrence of cerebral infarction. 2.Anti-platelet aggregation therapy: It mainly inhibits the aggregation and release of platelets so that they cannot form tiny thrombi. It is the basis of prevention and treatment of cerebral ischemia. 3.Vascular dilation therapy: vascular dilation therapy can increase blood flow supply and promote the establishment of collateral circulation, thus improving blood supply to brain tissues, which is a widely used treatment method for acute and chronic cerebral ischemia. 4.Activating and removing blood stasis herbal medicine: Activating and removing blood stasis herbal medicine can improve microcirculation and reduce blood viscosity, which has a certain effect on the treatment of cerebral ischemia and is more commonly used in the treatment of cerebrovascular diseases, with certain improvement of symptoms and preventive effects. 5.Surgical treatment: If cerebral angiography or Doppler confirms that there is more serious intracranial artery stenosis and ischemic symptoms are clear, surgical treatment can be considered after adequate evaluation. Angioplasty can directly improve blood supply, but because of the risks involved in surgery, it should be fully evaluated and carefully selected. In conclusion, there are many causes of cerebral ischemia, and the treatment means should be selected according to the etiology. For acute cerebral infarction and transient cerebral ischemic attack, comprehensive management should be carried out according to acute cerebral infarction, and for chronic cerebral ischemia, attention should be increased, and according to the situation, comprehensive treatment should be carried out.
