Numbness in half of the body in cerebral infarction is mainly considered to be caused by lesions in the thalamus or brainstem. Generally, after active treatment, some patients can be cured, but a small number of serious patients will be left with sequelae. Patients who have symptoms of half of their body going numb should immediately seek medical attention and follow medical advice to avoid affecting recovery.1. Hyperacute treatment: mainly within 6 hours, if the patient meets the indications, treatment of thrombolysis and embolization can be performed, which is a special treatment for cerebral infarction, and after opening the blood vessels, it can effectively improve the ischemia and hypoxia of brain tissue and restore brain function. At this time, patients who have undergone thrombolysis have a very high possibility of cure, especially mild patients, who can usually be cured; 2. Acute phase treatment: patients who do not have thrombolysis within 6 hours need to undergo acute phase treatment, including removing oxygen free radicals, improving microcirculation, and improving brain function. At the same time, patients should use drugs such as aspirin to antiplatelet aggregation and at the same time use drugs such as atorvastatin to stabilize plaque in order to treat acute brain infarction and improve symptoms, and the prognosis is usually better after the acute phase treatment; 3. Rehabilitation treatment: the more active the subsequent rehabilitation treatment, the better the recovery. Patients can choose suitable rehabilitation exercises according to their own conditions, such as brisk walking, jogging, swimming and walking. If the rehabilitation treatment is effective, some patients can even recover 80%-90% of the function of the limb.
