Cerebral atherosclerosis may cause cerebral insufficient blood supply, stroke and other diseases, so timely intervention and treatment are needed to prevent its progression. Cerebral atherosclerosis is one of the most common cerebrovascular diseases. It is a condition in which the walls of the cerebral arteries are damaged by damage to the inner lining, deposition of lipids, and accumulation of cellulose and platelets on the injured inner lining, which results in proliferation of connective tissues in the walls of the arteries, roughness and loss of elasticity of the inner lining, occlusion or narrowing of the lumen of the arteries, which causes a decrease in the amount of blood supplied to the brain tissues. Cerebral atherosclerosis is mainly caused by long-term smoking, hypertension, high blood pressure, high blood fat, diabetes and other factors, if there is no timely intervention and treatment, can be further progressed, will lead to cerebral vascular stenosis, and further can lead to insufficient blood supply to the brain, strokes, etc., easy to cause disability, and in serious cases, can be life-threatening. Therefore, people with cerebral atherosclerosis are advised to consult a medical professional for early intervention and treatment under the guidance of a physician to avoid further progression.
