人到老年,各种器官功能逐渐衰退,脑血管也不例外。脑血管本是有一定韧性和弹性的,随着年龄的增长,再加上饮食不合理,导致血液中血脂过高、动脉硬化和血管腔狭窄,脑血流量减少,从而引起脑组织缺血缺氧,严重时导致痴呆和中风。对此,应及早防治。一、脑动脉硬化的早期判断脑动脉硬化的表现,主要是慢性脑供血不足所致大脑皮层高级活动功能减弱。主要表现有:△记忆力衰退尤其是对人 People to the elderly, a variety of organ function decline, cerebrovascular is no exception. This is a certain degree of cerebral vascular toughness and flexibility, with age, coupled with unreasonable diet, leading to hyperlipaemia in the blood, arteriosclerosis and stenosis, decreased cerebral blood flow, causing ischemia in brain tissue Oxygen, in severe cases, causes dementia and stroke. In this regard, prevention and treatment should be early. First, early judgment of cerebral arteriosclerosis The performance of cerebral arteriosclerosis, mainly due to lack of chronic cerebral blood supply due to the decline of advanced activities of the cerebral cortex. Main performance: △ memory decline, especially for people
