Cavitary infarction, also known as lacunar cerebral infarction, has a better prognosis and does not matter in most cases, but patients need to go to the hospital in time. Cavernous cerebral infarction occurs mostly in the deep part of the brain, and a small portion occurs in the cerebral cortex. Cavernous cerebral infarction is a localized ischemia, hypoxia, and necrosis of brain tissue caused by narrowing and occlusion of small blood vessels in the brain. Among all types of cerebral infarction, cavernous cerebral infarction causes milder clinical symptoms due to its small infarct area and relatively less brain cell damage, and may present with symptoms such as mild limb numbness, weakness, dizziness, and crooked mouth, and does not usually cause severe hemiplegia symptoms. Some patients may even have no clinical symptoms, and the cavernous infarction foci are found during health checkups. Cavernous cerebral infarction needs to go to the hospital in time, timely treatment, and follow the doctor’s instructions to use drugs anti-platelet, lipid regulation to stabilize plaques, improve circulation, and so on. Patients should pay attention to adjust the lifestyle, low-salt and low-fat diet, quit smoking and drinking, and control the blood pressure, blood sugar and blood lipid.
