The golden recovery period of brainstem infarction is within three months, and the recovery is slower above 6 months, but clinically very few patients are still continuing to recover their functions more than one year after the onset, but the initial three months are the most important. Brain tissue necrosis and edema after cerebral infarction, brain tissue edema gradually decreases in 7-14 days, brain tissue liquefaction and necrosis, patients with cerebral infarction are mostly middle-aged and elderly, most of them combined with hypertension, diabetes, coronary heart disease and dyslipidemia, etc. The clinical performance and the length of recovery period also depend on the size and location of the lesion, with large lesions and important parts of infarction, the danger period is prolonged and the recovery period is long, with small lesions and relatively unimportant infarction In the case of small and relatively unimportant infarcts, patients can recover better within 14, even without leaving any sequelae and without affecting their work and life. Patients with cerebral infarction are recommended to actively rehabilitate and exercise, and since patients with cerebral infarction are mostly combined with risk factors such as hyperglycemia and diabetes, patients should pay attention to controlling risk factors, improving bad living habits and taking medication on time after discharge, which plays an important role in improving future quality of life and reducing recurrence.
