Acute cerebral ischemia has the possibility of complete cure if actively treated, while chronic cerebral ischemia cannot be completely cured. For acute cerebral ischemia patients, if they seek timely medical treatment after the onset of cerebral ischemia to solve the causes of cerebral ischemia (e.g. cerebral thromboembolism, severe narrowing of cerebral blood vessels), such as thrombolysis or mechanical extraction of thrombus, stenting, etc. to restore the blood flow of the brain tissue in the ischemic area, the patients may be able to recover to the state before cerebral ischemia. If patients with cerebral ischemia are not treated in time, it will lead to necrosis of brain tissues, which will affect the neurological function and symptoms such as hemiplegia, hemianopsia, aphasia, sensory impairment, etc., and then it is generally difficult to be cured completely. Chronic cerebral ischemia caused by long-term high blood pressure, diabetes mellitus, smoking, etc. cannot be completely cured either, and risk factors need to be controlled to prevent its further progression. When cerebral ischemia is detected, it is recommended to seek medical advice and treatment in a timely manner.
