Patients with anemia and cerebral insufficiency should take iron supplements and nutrients in a timely manner, adjust the amount of nutrients in three meals a day, and increase the amount of vitamins and various proteins in the body as much as possible, all of which can play a role in improving the nutrients in the body and thus improve the symptoms of anemia. Patients with cerebral blood supply deficiency should quit smoking, prohibit excessive alcohol consumption, and actively treat hypertension to stabilize blood pressure, which can effectively ensure the blood supply from the heart to the brain. At the same time, anti-platelet drugs, such as aspirin, can be used to effectively stop platelet clots and facilitate blood circulation, and vasodilator drugs can also be used to improve the microcirculation of the brain. If patients have carotid stenosis, they can be treated with surgery to relieve the symptoms of insufficient blood supply to the brain by placing carotid stents.
