(16,474 posts)increasingly called Alzheimer's regardless despite there being no way to diagnose this disease without an autopsy.
A few years ago, on 60 Minutes, there was a story on a group of nonagenarians who were part of a years long study of mental acuity. The fascinating part was that one participant was mentally sharp until death, but the autopsy showed his brain was full of the plaques and tangled associated with Alzheimer's. Another participant clearly had Alzheimer's like dementia, yet his autopsy showed none of the plaques and tangles. Clearly there's still a lot of unknowns.
Another thing that can cause fuzzy thinking and confusion is dehydration. Older folks don't always drink enough water causing leading to inadvertent dehydration and electrolyte imbalance. This happened to me, but resolved after rehydration and some potassium rich food.
