Cerebral vascular thinning are all congenital thinning, there is no acquired causes can lead to cerebral vascular thinning. Cerebrovascular degeneration mainly refers to the thinning of the lumen of cerebral blood vessels, which is mainly due to the thickening of the intima of blood vessels caused by atherosclerosis, and in serious cases, the formation of thrombus attached to the wall, which can lead to the thinning of cerebral blood vessel lumen. For the thinning of the lumen of the cerebral blood vessels, the patient may have the symptoms of insufficient cerebral blood supply, and in severe cases, there may also be the occurrence of blood theft, such as blood theft from the subclavian artery. Cerebral vascular thinning is mostly seen in middle-aged and old people, but young people with immunologic factors can also cause abnormalities in the lining of cerebral blood vessels. The consequence of cerebral vascular thinning is mainly the occurrence of cerebrovascular disease, clinically ischemic cerebrovascular disease is common, and should be given to the cause of cerebral vascular thinning treatment. For cerebral vascular thinning, clinically, patients can be given oral statins to protect the endothelium of the blood vessels, but also to give patients a regular check of blood vessel changes, if necessary, with the improvement of the circulation of the drug.
