Patients with left cerebral blood supply deficiency can take Cipro, Ginkgo biloba drops or Peiyuan Tongbao capsule orally, mainly for middle-aged and elderly people due to cerebral arteriosclerosis. Patients often have hyperglycemia, hyperlipidemia and hypertension in combination, so the treatment should control the patient’s blood pressure, blood lipid and blood glucose at the same time, mainly giving levamlodipine and amlodipine besylate to regulate blood pressure. Metformin and insulin should be given to control blood glucose. Simvastatin, Rosuvastatin and Atorvastatin are given to regulate lipids to stabilize plaque and prevent atherosclerosis. In young patients, relaxation, stress reduction and sleep improvement should be the main treatment to relieve the patient’s symptoms, and if necessary, oral glutamate and neurotropic drugs such as vitamin B1 and B12 can be given.
