Patients with cerebral infarction who have obvious impairment of consciousness are usually due to the aggravation of the disease. The impairment of consciousness occurs because of the large area of infarction, ischemia, edema in the cerebral hemispheres, and there may be functional deficits in the mesencephalon and brainstem, which is why there are different degrees of impairment of consciousness, and the impairment of consciousness, if it occurs for a long time, may even lead to brain herniation and cause death. Cerebral infarction death is caused by significant impairment of blood flow to the brain, causing localized ischemia and hypoxia, which leads to ischemic necrosis and softening of restricted brain tissue resulting in cerebral infarction death. If impaired consciousness occurs in a short period of time, it can be corrected after improving ischemia with medication and usually does not leave significant sequelae, but if impaired consciousness occurs for a long period of time marks a poor prognosis.
