随着年龄的增长,人们常常会抱怨思维变得迟缓,记忆力、计算力等下降;以前能轻松完成的事情,现在却要花费很多的心思去完成。上述表现人们形象地称之为脑子“生锈”了,就好比机器生锈运转不灵活一样。神经影像学及神经心理学研究发现,脑子“生锈”可在脑微出血方面找到相对应的答案。所谓脑微出血是磁共振成像(MRI)上较常见的脑小血管病变标志,是脑内微小血管病变所致的一种脑实质亚临床损害,其实质是含铁血黄素沉积。含铁血黄素沉积是 As you grow older, people often complain that thinking becomes sluggish, memory, computational power, and the like drop down; things that you can do with ease are now done with a lot of thought. The performance of the image of the people called the brain “rust ”, like the machine rusty operation is not the same. Neurological imaging and neuropsychological studies have found that the brain “rust” can find the corresponding answer in brain micro-hemorrhage. The so-called cerebral micro-hemorrhage is a more common magnetic resonance imaging (MRI) signs of cerebrovascular disease, brain microvascular lesions caused by a brain subclinical damage, its essence is hemosiderin deposition. Hemosiderin deposition is
