I so wished i had known about MCI sooner. I suspected a memory problem with my husband and he saw a neurologist who told us about some brain cell but fora man 87 not too far off normal aging. The doctor did not mention MCI so at times I thought he perhaps was miss diagnosed as he seemed okay and his family just said “ dad has always been self serving” selfish. I thought that strange because most grown people are not out and out selfish. My 2nd marriage after 45 years married to a man who had died. So of course this husband wasn’t quite as familiar to me. Anyway many times i was rude and angry with my present husband because of some of his unthoughtful ways. Now since reading about MCI i feel bad. My husband now is far enough along with his brain problem, I'm not sure what kind, anyway he Sleeps 16 hr aday, during his waking hours eats very little drinks very little and sits and looks into space does not have conversation answers only yes or no questions
