Numbness of the tip of the tongue, if it is an elderly patient, should be alert to the occurrence of atherosclerosis, or even the occurrence of a small lacunar infarction in the brain. It is recommended that patients go to the hospital for routine biochemistry, carotid ultrasound, and nuclear magnetic head examination to clarify whether there are risk factors that lead to atherosclerosis. High blood pressure, high blood lipids, high blood sugar, overly salty diet, physical inactivity, smoking and drinking can all lead to atherosclerosis. Carotid ultrasound is to check whether there is plaque or narrowing of the blood vessels in the neck, that is to say, to confirm whether the patient has atherosclerosis or not, and nuclear magnetic head examination is to make it clear whether there is cerebral infarction in the patient’s skull or not, and according to different diseases, there can be different treatments. If the patient does not have atherosclerosis or cerebrovascular disease, simple numbness of the tip of the tongue is considered peripheral neuropathy, oral vitamin B1 and vitamin B12, 1 tablet / times, 3 times / day, oral half a month is a course of treatment.
