Brain infarction requires a hospital stay of 7-14 days, but the exact length of stay depends on the patient’s condition. The length of hospitalization for brain infarction patients needs to vary from person to person, and generally requires a hospital stay of 7-14 days. If the condition of cerebral infarction is mild, such as mild limb weakness, slightly clumsy speech, or mild numbness of the limbs, the symptoms can be relieved quickly after giving the patient symptomatic treatment, and he or she can be discharged in 5-7 days. However, for patients with severe cerebral infarction or even coma, as well as patients with other complications, the hospitalization time is relatively long, and some serious patients still need to go to rehabilitation hospitals to continue inpatient rehabilitation after discharge. However, both patients with mild cerebral infarction and patients with severe cerebral infarction need to take medication to actively control the risk factors of cerebrovascular disease and do a good job in secondary prevention of cerebrovascular disease after discharge.
