Cavernous cerebral infarction is a type of small artery occlusive cerebral infarction, which occurs in ischemic microinfarcts of deep perforating arteries, and is clinically classified into four main types: purely motor mild hemiparesis, dysarthria-clumsy hands and feet syndrome, purely sensory stroke, and ataxic mild hemiparesis. The subacute stage is usually more than 14 days after the onset of the disease, and the lesion is slightly high signal on DWI. Patients should complete relevant examinations to see if there are relevant risk factors such as hypertension, diabetes, hyperlipidemia, etc., as well as whether there are bad habits such as smoking, drinking alcohol, staying up late. For cerebral infarction itself, it is recommended to take antiplatelet aggregation drugs such as oral aspirin for antiplatelet aggregation, atorvastatin and other drugs to lower blood lipids for secondary prevention.
