Minor cerebral infarction in the elderly is not serious and belongs to lacunar cerebral infarction, which has a relatively high incidence in cerebral infarction disease and can turn out to be about 30% of cerebral infarction. Lacunar cerebral infarction is clinically asymptomatic in many patients, called asymptomatic lacunar infarction, and some patients show relatively mild clinical symptoms and may have mild limb sensory abnormalities, limb weakness, and cloudy speech, but the prognosis is good and easy to recur. Recurrent attacks of lacunar cerebral infarction occur mainly due to hypertension, diabetes, hyperlipidemia, smoking, alcohol consumption and other undesirable factors. Patients who have lacunar infarction should strictly control blood pressure, use statin lipid-lowering drugs appropriately to reduce the degree of atherosclerosis, and must take oral anti-platelet aggregation drugs, such as aspirin. If the patient cannot tolerate aspirin, oral clopidogrel hydrogen sulfate should be given to inhibit platelet aggregation and prevent the re-formation of small blood clots in the blood vessels.
