Scattered lacunar cerebral infarction foci in the brain are old cerebral infarcts, so in terms of treatment, the main thing is to start secondary prevention of cerebrovascular disease to prevent the reoccurrence of cerebral infarction and prevent patients from forming large cerebral infarcts, so the treatment of patients should take long-term oral BAY aspirin or Polivy antiplatelet aggregation therapy, and also perform ultrasound examination of the neck vessels. If the patient has unstable plaques in the neck blood vessels, and if the blood lipids are also high, the patient should be given oral atorvastatin calcium tablets or rasulvastatin calcium tablets to lower the lipids and stabilize the plaques to avoid the patient’s new occurrence of cerebral infarction. It is also very important to actively regulate these risk factors such as hypertension, diabetes and hyperhomocysteinemia, and it is also very important in terms of diet, patients should have a low salt and low fat diet, control their own weight, participate in more physical activities and stop smoking and limit alcohol to avoid damage to the vascular endothelium.
