Cerebral infarction causes cerebellar atrophy, patients should usually take oral aspirin to antiplatelet aggregation and improve blood supply to the brain. Patients should take drugs such as Ginkgo biloba extract tablets, blood plugging tablets, and vermifuge snake tongluo capsules. Cerebellar atrophy can occur for many reasons, including cerebellar infarction and cerebellar hemorrhage. There are also predisposing factors for cerebellar atrophy, such as hypertension, hyperlipidemia, diabetes, coronary heart disease, and alcohol may induce cerebellar atrophy. Therefore, patients with hypertension should take antihypertensive drugs, such as telmisartan. If they have hyperlipidemia, they should take oral atorvastatin calcium tablets to lower lipids, stabilize plaque, and protect the vascular endothelium. If there is diabetes mellitus, insulin or oral hypoglycemic drugs such as oral metformin should be used to control the patient’s blood sugar, prevent the patient from developing cerebral atherosclerosis and prevent the progression and aggravation of cerebellar atrophy. Patients should usually be treated with oral medications that improve brain metabolism, such as oracetam and cytarabine sodium tablets. If cerebellar atrophy causes ataxia in patients, patients can take buspirone.
