Cerebral infarction unconsciousness is generally considered to be caused by brainstem infarction, massive cerebral infarction or cerebral infarction. 1. Brain stem infarction: If the blockage site of cerebral infarction is in the brain stem, it may involve the upward reticular activating system in the brain stem, leading to the patient’s consciousness disorder and entering into coma. 2. Large cerebral infarction: if large cerebral infarction occurs, it may cause damage to the cerebral cortex or damage to the upward reticular activating system, resulting in the patient falling into a comatose state. If patients with cerebral infarction do not wake up, it is recommended to cooperate with doctors as soon as possible to improve the relevant examinations, find the triggering causes, and take effective treatment measures in time.
