Neurology can treat high blood pressure because high blood pressure easily causes cerebral arteriosclerosis, cerebral vascular spasm, and even cerebral vascular rupture, which leads to cerebral infarction, cerebral hemorrhage and other cerebrovascular diseases, so high blood pressure and cerebral vascular disease have a close connection. Neurologists need to apply antihypertensive drugs to control blood pressure treatment while treating cerebrovascular diseases. In addition, patients with high blood pressure are recommended to have a low-salt diet, take oral antihypertensive drugs regularly, and monitor their blood pressure in order to keep it in the normal range. In case of patients with cerebral infarction, it is recommended not to control their blood pressure too low, especially for the elderly, and it is recommended to control their blood pressure below 160/90mmHg, and preferably not lower than 120/80mmHg because too low a blood pressure can aggravate the blood supply of the cerebral vessels and cause the occurrence of cerebral infarction. Insufficient blood supply to the brain and cerebral vessels, causing the occurrence of cerebral infarction.
