Cerebral infarction and cerebral hemorrhage sequelae are not different in nature, but both are signs of neurological deficits resulting from the destruction of brain tissue due to infarction or hemorrhage. After treatment and rehabilitation, if the loss of function does not return to normal after 6 months or more, it is called a sequelae. The most common sequelae are hemiplegia, or hemiplegia. The specific sequelae are related to the location of the cerebrovascular disease, with infarction or hemorrhage in the basal ganglia being the most common, so most patients have hemiparesis and hemianesthesia. If it occurs in the left hemisphere, it is often accompanied by aphasia. If the patient has frontal and temporal lobe infarction, there may also be residual mental impairment and poor memory. If it is a cerebellar infarction, there may be dizziness, unstable walking, and ataxia. In the case of brainstem infarction and hemorrhage, there is often paralysis of all four limbs as well as swallowing disorders, choking and coughing, and hoarseness of voice.
