The causes of cerebral ischemia are complex, and different treatments should be given for different causes. 1, cerebral artery stenosis or occlusion caused by cerebral ischemia: cerebral atherosclerosis is the main cause, the treatment should control the risk factors, such as quit smoking, quit drinking, control blood pressure, blood sugar, lipids in the normal range; on the other hand, anticoagulation, antiplatelet aggregation, statin modulation to stabilize the plaque, improve cerebral circulation to prevent further development of plaque, when the plaque blockage of blood vessels exceeds 70%, patients are recommended to implant stents treatment. 2. Embolism caused by embolism: embolism mainly comes from atheromatous plaque shedding and cardiogenic embolism shedding. For example, atrial fibrillation is the main cause of cardiogenic embolus formation. When patients find atrial fibrillation, they should be treated early to turn the heart rhythm and take oral anticoagulant drugs such as Warfarin to prevent thrombus formation. 3, hemodynamic, hematological and other factors: such as myocardial infarction, hypotensive shock, etc. to make brain tissue ischemia, should be the main focus of active treatment of the original disease, but also can use some drugs to protect brain tissue to assist in treatment. In addition to the above treatment, it is recommended that patients regularly visit hospitals to check blood pressure, blood lipids, blood glucose, vascular ultrasound, etc., and actively seek treatment in neurology when abnormalities are detected.
