Cerebral ischemic degeneration foci refer to the changes caused by atherosclerosis of the brain arteries and thickening of the lumen of blood vessels, resulting in the blood supply to the patient’s brain being affected, causing ischemia and hypoxia in brain cells and brain tissue. Clinically, there will not be acute neurological deficits, but patients may often have dizziness, headache, inattention, memory loss, and decreased neurological function of the brain. Cerebral ischemic degeneration foci should be taken seriously by patients, because this condition indicates that the capillary sclerosis of the cerebral arteries of patients is relatively heavy, and timely intervention must be carried out. Patients are at a higher risk of lacunar cerebral infarction, so it is recommended to start secondary prevention medication for cerebrovascular disease, such as oral BAY aspirin to prevent platelet aggregation and thrombosis, or oral clopidogrel sulfate for treatment. At the same time, active and effective use of medication for prevention of risk factors such as hypertension, diabetes mellitus and hyperlipidemia.
