Alzheimer's?

I agree with @BPS. I often questioned if my DH really did have it? We would have long periods of everything appearing to be fine, although he would tell me he felt “foggy.” Fast forward six years or so and we have moved into an obvious “he definitely has it” stage. Because everything progressed slowly, I didn’t really recognize all the small, incremental changes that occurred over all these years. Little by little I did more and more and more. And now it’s obvious he could not function alone.

I assume your doctors did brain imaging (CT etc.) to rule out other possible causes such as brain tumor or stroke. If those are not the cause of her problem, then I'm afraid Alzheimer's disease is probably the culprit.

My wife was diagnosed with AD in 2017, and we were warned of possible personality changes. None appeared until this year, when she became agitated and angry. This has improved with medication, and she actually behaves much like the loving young woman I married in 1967. But she is very easily confused. I have to help her dress, or she will have both socks on one foot and her shoes on the wrong feet. She can't sew, use a telephone, read a book, cook, or start her car. Sometimes she can find the bathroom in her own house, and sometimes there are "so many doors." I have no hope that her condition will not progressively and unpredictably worsen for the rest of her life.

Life with AD is like being on a one-way staircase, leading down. At unpredictable times we find ourselves one more step nearer the bottom.

I'm sorry you are here with us, and that I don't have any more cheerful answer for you.

I also experience that same thing. Sometimes the changes are so subtle you don't even know they happened until you can look back. I ask family members and friends that dont see him frequently if they see changes. When you are in the middle of it day in and day out you kind of get use to the behaviors and make the necessary adjustments without even thinking about it.

DH was diagnosed with ALZ a little over a year ago. He was already in Stage 6 (per Tam Cummings chart). In retrospect, I can see executive function issues and then increasing memory issues going back 10 years. I was providing so much scaffolding for him that I was unaware of, having been told that his problems were just due to old age (he is 93). The diagnosis was a severe blow for me. I was truly the frog who was being slowly boiled alive. Coming to this discussion board and learning about the stages of ALZ made me realize just how bad things were. He is now is late Stage 7, and our journey will be ending in the near future.

My DH used to say he felt “foggy” in the mornings when he woke up often and he seemed distressed & disoriented because of it then we got our diagnosis.
