Sensory dysfunction may be caused by cerebral ischemia, Guillain-Barré syndrome, diabetes mellitus, vegetative nerve disorders, etc., and aspirin and methylcobalamin need to be taken to address the cause. 1. Cerebral ischemia: atherosclerosis of the internal carotid artery, vertebral artery and other blood vessels supplying blood to the brain leads to narrowing of the lumen, and sensory dysfunction occurs due to insufficient blood supply to the brain. Aspirin, clopidogrel, atorvastatin and other medicines can be taken for treatment. 2. Guillain-Barré syndrome: autoimmune dysfunction leads to demyelinating lesions of peripheral nerves, resulting in sensory dysfunction. You can take vitamin B, vitamin C, prednisone and other drugs to treat it. 3. Diabetes mellitus: long-term high blood sugar level leads to chronic complications of peripheral neuropathy, so there is sensory impairment. You can take medicines such as metformin, dagliflozin, methylcobalamin, epothilone and so on. 4. Vegetative nerve disorder: sympathetic and parasympathetic nerve dysfunction leads to sensory disorder, you can take glutamine, methylcobalamin and other drugs. Patients should go to the hospital in a timely manner, under the guidance of the doctor, improve the relevant examination, to clarify the cause of the disease, to be systematic and regular treatment. Drugs should be used under the guidance of a physician.
