Does the MMSE take low IQ into account when testing for dementia? My DH is a genius at mechanical things. He can fix just about everything and even investigate and find a hard to detect issue (like a short in our RV that took him 2 days to track down to a very unlikely source but he did it!). However, at everything else...he is fairly clueless. He struggled through school and barely graduated from high school. He has a hard time following plot lines on TV shows and movies, he does not read unless it is about RV's or cars or camping, he gets confused about his doctor appointments and medications, has a hard time following conversations, cannot cook or do laundry or plan a dinner or host friends or family. I do all of that plus our finances. How can he be brilliant at mechanical things but barely get by on almost everything else? His MMSE score was 25. The neuro says he is "borderline" and wants to see him in 6 months and perhaps every 6 to 12 months thereafter. I am concerned that he may score lower at his next exam and test but that it is his IQ and not necessarily a cognitive issue that causes the low score.
