Sudden numbness of the hands without sensation is mostly considered to be caused by cerebrovascular diseases, which can be seen in the thalamus lesions, or may be caused by lesions in the basal ganglia region or the corona radiata region. It may be cerebral infarction or cerebral hemorrhage, which is usually seen in middle-aged and old people, and most of the patients may have a history of hyperlipidemia, diabetes mellitus, and hypertension. Cerebral hemorrhage usually starts in the middle of activity, while cerebral infarction usually starts in the quiet state, and craniocerebral CT examination can be used to make a clear diagnosis. If the patient’s numbness symptom is serious, some nutritive nerve drugs can be used, and clinically, methylcobalamin and adenosylcobalamin are usually applied, and at the same time, the original disease should be actively treated. Patients with cerebral infarction are mainly treated with antiplatelet aggregation therapy, neuroprotective therapy and improvement of blood circulation therapy. Drugs commonly used in antiplatelet aggregation therapy include aspirin; drugs commonly used in neuroprotective therapy include olanzapine and perphenazine, and ceruloplasmin myostatin; drugs used in improvement of blood circulation are generally used in shuxu hainen and vinblastine, and when the condition is stabilized, rehabilitation and acupuncture can be carried out.
