If cerebral arteriosclerosis is severe, there is a risk of forming cerebral hemorrhage and cerebral infarction. Mechanism of formation of cerebral infarction: cerebral arteriosclerosis is gradually severe, lipids will accumulate in the blood vessels and will lose elasticity. In this case, especially the accumulation of lipids will gradually cause narrowing in the lumen of blood vessels, and blood flow will not be able to pass or decrease. When occasionally in 1 or 2 cases of hypotension, the symptoms of cerebral infarction will develop, with dizziness, nausea, numbness and weakness of the limbs, and speech dysfunction. In terms of cerebral hemorrhage, because of the decline in elasticity, the body’s ability to regulate blood pressure decreases, just like the aging of rubber, once the blood pressure increases overnight and cannot be significantly controlled, it will rupture the blood vessels and cause cerebral hemorrhage. Therefore, for cerebral atherosclerosis, active treatment, stabilization of plaque and softening of blood vessels are very helpful to prevent the occurrence of cerebral hemorrhage and cerebral infarction in the future.
