Normal activity of the brain requires adequate blood circulation. If the cerebral blood vessels are blocked somewhere in the brain, resulting in ischemia and hypoxia of part of the brain tissues, blood flow slowly decreases, forming chronic cerebral insufficiency of blood supply, which results in dizziness, headache, headache, dizziness and swelling of the head, loss of memory, and forgetfulness. Patients are usually accompanied by a history of cerebral arteriosclerosis, hypertension, hyperglycemia, hyperlipidemia, and need to monitor blood pressure, blood glucose, blood lipids, and go to the hospital to do head CT or MRI to make a clear diagnosis. Oral flunarizine hydrochloride capsules, atorvastatin tablets and nourishing blood and brain granules can be taken.
