有研究预测，85岁以上，1/3会罹患dementia。 词源说dementia这个词是这样来的，de就是失去，mentia就是心智。换句话讲，85岁以上1/3会失智，再粗暴一点理解，会疯。 Etymology borrowed from Latin dēmentia "derangement, insanity, folly," noun derivative of Latin dēment-, dēmens "out of one's mind, frenzied, insane," from dē- DE- + -ment, -mens, adjective derivative of ment-, mens "power of reason, mental balance, mind" https://www.merriam-webster.com/dictionary/dementia  |
