Insufficient blood supply to the brain is mainly managed by treating possible risk factors, such as taking medication such as amlodipine to control blood pressure in patients with high blood pressure, taking atorvastatin to stabilize fatty plaques in patients with significant atheromatous plaques in the brain arteries, and placing stents to improve cerebral blood flow in patients with severe narrowing of the carotid artery and other large arteries in the brain. Inadequate blood supply to the brain may be discovered during a CT or MRI of the head. Common triggers are risk factors for cerebrovascular disease such as high blood pressure, diabetes, and hyperlipidemia. For patients with high blood pressure, antihypertensive drugs such as amlodipine and Benadryl are taken to lower the blood pressure to normal. Patients with diabetes can be treated with glucose-lowering drugs such as insulin injections or oral metformin. Patients with hyperlipidemia should take lipid-regulating drugs such as atorvastatin to lower blood lipids and stabilize fatty plaques. If the cerebral blood supply is insufficient due to severe stenosis of the carotid arteries or large intracranial arteries, you may consider receiving treatment by disposing stents into the stenotic arteries. In mild cerebral hypoperfusion, patients may not have any symptoms and may not necessarily need treatment. It is recommended that the patient go to the hospital to have a full understanding of the patient’s condition before deciding on the appropriate treatment plan.
