My mom has Alz/dementia, went to the ER because of choking and subsequent aspiration pneumonia. Stayed 4 nights, did not come home confused about the house, but now sleeping through the night (prior she woke various times/night) and is having more and more trouble walking, on stairs, and getting up from chair. She also needs supplemental oxygen since the hospital visit, which we hope is not long term. Does this rapid change in physical level seem par for the course, and is it possible that she can re-coup any abiliities? Before this she was slow on stairs, but ok, and walking without assistance. Sometimes she couldn't get up from a chair, but it's much worse now. Thoughts appreciated.
