If the symptoms of numbness in the right hand and foot suddenly appear, it is considered to be caused by acute cerebrovascular disease, which may be caused by transient ischemic attack, cerebral infarction, or mild cerebral hemorrhage. Patients should consult a hospital promptly, first of all, to improve the head CT examination to determine whether it is caused by bleeding, and if it is a cerebral hemorrhage, the patient should be absolutely bed-rested. In the acute stage, dehydration should be given to lower the cranial pressure to prevent further bleeding, and some complications of cerebral hemorrhage should be prevented for treatment. If there is no high-density shadow on the head CT, then the patient is suffering from ischemic cerebrovascular disease and should also be given treatment to activate blood circulation and improve circulation. According to the time window of the patient’s visit and some underlying diseases of the patient, thrombolysis, fibrin-lowering, anticoagulation, antiplatelet and other treatments can be chosen. There is also a need to give brain protection, remove oxygen free radicals, try to save the ischemic semidark zone, alleviate the symptoms of impaired brain nerve function of the patient, and relieve the numbness of the right hand and foot.
