什么是脑萎缩 郑炳旭 吉林省脑科医院
所谓脑萎缩是脑体积的缩小，因为脑袋颅骨是相对密闭的空腔，体积是固定的，然后里面装的是脑组织，体积变小了，空隙变大时做核磁CT检查就会提示脑萎缩，而这个脑萎缩是很多疾病出现的后果，而不是说它引起了哪些病，所以从理论上所有的脑部疾病发展到晚期都可以出现脑萎缩

What is brain atrophy
Brain atrophy is the reduction of brain volume, Because the skull is a relatively closed cavity, The volume is fixed, And then it's filled with brain tissue, It's smaller, When the gap becomes larger, MRI and CT will indicate brain atrophy, And this brain atrophy is the result of many diseases, It's not about the diseases it causes, So in theory, all brain diseases can develop into brain atrophy in the later stage
