The 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 in some brain tissues, blood flow slowly decreases, forming chronic cerebral insufficiency of blood supply, resulting in dizziness, headache, head sinking, dizziness, memory loss, forgetfulness, etc. Patients usually have a history of cerebral atherosclerosis, hypertension, hyperglycemia, and hyperlipidemia, so they need to monitor blood pressure, blood sugar, and blood lipids, and go to the hospital for head CT or MRI to make a clear diagnosis. You can take flunarizine hydrochloride capsules, atorvastatin tablets and blood-raising and brain-clearing granules orally.
