Cerebral infarction is mostly numbness all the time, that is, the numbness symptoms are mostly persistent.
Cerebral infarction is a kind of ischemic cerebrovascular disease, which means that the blood circulation in the brain is impaired, resulting in ischemia and hypoxia necrosis of brain tissue in the corresponding blood supply area, and then focal neurological deficits occur.
After cerebral infarction, brain tissues that have been ischemic and necrotic are not regenerated, and the symptoms of neurological deficit caused by it are also persistent and unrelieved. However, a few brain tissues around the lesion that have not yet been necrotic can recover their original functions after the blood supply is restored, so the symptoms may be relieved to a certain degree, but they will not disappear, and so the symptoms of cerebral infarction, such as numbness and weakness of the limbs, are persistently present.
Cerebral infarction patients are advised to seek medical treatment in time and actively cooperate with doctors to improve the symptoms of numbness of limbs.
