目前医学家已发现,大脑中β-淀粉样蛋白变异等蛋白质异常,以及海马区代谢能力下降、大脑体积萎缩等与老年痴呆发病机制有关。意大利医学家弗里索尼明确提出:“先是大脑β-淀粉样蛋白异常,然后是代谢障碍,接着便是脑萎缩。”他说,年幼时有轻微脑功能障碍如轻度认知功能障碍的人,以后患老年痴呆的可能性更

At present, medical scientists have found that abnormalities in the brain, such as β-amyloid protein variation, as well as decreased ability to metabolize the hippocampus, brain volume shrinkage and the pathogenesis of Alzheimer’s disease. Frisonelli, an Italian medical scientist, clearly stated: “First, the brain is deficient in beta-amyloid, then metabolic disorder, and then brain atrophy.” He said that when you are young you have mild brain dysfunction such as mild cognitive impairment People with disabilities, the future possibility of dementia more
