Patients with cerebral infarction can be discharged after about one week of hospitalization. For example, lacunar cerebral infarction causes patients to have symptoms of focal neurological deficits, which are manifested as symptoms of inflexible movement of the lateral limb, numbness of the limb, clumsy speech, dizziness, and choking on drinking water. Through about seven days of treatment, the patient can be discharged after his condition is probably stabilized. If the patient has a large cerebral infarct area, the discharge time will be decided according to the condition. If the patient is a large cerebral infarct in the cerebral hemisphere, it is easy to combine with serious problems such as pneumonia, gastrointestinal bleeding and stress ulcers, and the patient may have an altered state of consciousness and be in a drowsy and comatose state, so the treatment period is relatively long.
