Cerebral atherosclerosis mainly causes chronic cerebral ischemia, which in turn leads to the decline of brain function, generally with insidious onset and slow development, and should be given sufficient attention. There is no special treatment method at present. On the one hand, we can improve brain circulation and promote brain metabolism to improve brain function, and on the other hand, we should actively control the risk factors of atherosclerosis to prevent disease progression. To improve the symptoms: cerebral atherosclerosis will lead to a decline in cerebral blood supply, the first treatment is to use drugs to improve cerebral circulation, mainly calcium antagonists such as nimodipine and flunarizine; cerebral vasodilator drugs such as nimeglumine and Chuanxiongzine, etc. For those with decreased cerebral function, drugs to promote cerebral metabolism can be used, such as aniracetam and staphylococcus aureus; patients with carotid atherosclerosis lesions can use antiplatelet drugs, such as aspirin In patients with carotid atherosclerosis, anti-platelet agents such as aspirin, clopidogrel, and clopidogrel can be used. Prevention and treatment: Prevention should be the main focus of this disease, actively control the risk factors of atherosclerosis, including: control hypertension, treatment to meet the standard; control low-density lipoprotein-based lipid-lowering treatment, appropriate use of statin lipid-lowering drugs; regular monitoring of blood sugar, effective control of diabetes; improve lifestyle, quit smoking and limit alcohol, increase outdoor exercise, reduce weight, balanced diet, maintain psychological balance, etc. The initial symptoms of cerebral atherosclerosis are not obvious, and the symptoms of neurological impairment caused by chronic cerebral insufficiency are scattered and atypical, which can be easily ignored.
