The most common and main consequence of cerebral blood supply insufficiency is cerebral ischemic encephalopathy. If the cerebral blood supply is insufficient for a long time and is not controlled, it can lead to hypoxic-ischemic encephalopathy, and even cerebral infarction when the condition is serious. Suffering from ischemic encephalopathy, it is easy to lead to inattention of thinking, memory decline and even intellectual impairment. Cerebral infarction includes cerebellar infarction, brainstem infarction and cerebral hemisphere infarction. Patients with brainstem and cerebellar infarction are prone to nausea, vomiting, dizziness, ataxia, etc. Patients with cerebral infarction will have language dysfunction and hemiplegia. In severe cases, brain edema and intracranial hypertension may occur, which may lead to disturbance of consciousness or even death.
