The recovery time of cerebellar infarction is closely related to the size of the infarct, comorbidities and age of the patient, etc. Generally speaking, the recovery period of cerebral infarction is about 3 months, and some patients are still continuing to recover their functions for more than 1 year clinically, but the initial 3 months are the most important. Patients with cerebral infarction are mostly middle-aged and elderly, and most of them are combined with hypertension, diabetes, coronary heart disease and dyslipidemia, etc. The length of recovery period depends on the size of lesions and comorbidities; patients with large lesions, many comorbidities, old age and multiple cerebral infarctions have a longer recovery period and may have continuous balance dysfunction; patients with small lesions, young age, first onset and few comorbidities can recover within 14. Cerebellar infarction should be actively rehabilitated with balance function exercise, control of risk factors, improvement of bad habits, and regular medication after discharge, and many patients can basically recover through functional exercise without leaving obvious sequelae.
