Cerebellar death refers to cerebellar infarction, the cerebellum is an important center in the nervous system to regulate the movement, mainly responsible for maintaining the balance of the body, regulating muscle tone and the body’s random movement. After cerebellar infarction, patients will show severe dizziness, nausea, vomiting, ataxia, inability to point to the nose and fingers, walking to one side, cerebellar language, unclear speech, dysarthria, patients can not walk in a straight line, can not pick up things accurately, patients with bowel movements, and there will be hypotonia, tendon reflexes are weakened or disappeared. The treatment of cerebellar death is the same as the treatment of other types of cerebral infarction, which should be selected according to the time of the onset of the patient, and it can be done through intravenous thrombolysis to dissolve the thrombus blocked in the blood vessel and promote the recovery of the patient’s neurological function. However, cerebellar atrophy is relatively more dangerous. Once the area of cerebellar atrophy is relatively large, cerebral edema occurs, which can easily lead to brainstem compression.
