I have just returned from visiting my 89-year-old father, who has vascular dementia (and lives abroad.) In the two months since I last saw him he seems to have deteriorated. He suffered gastrointestinal bleeding two months ago, but recovered. However, his appetite, which was robust to say the least, has diminished, although he is eating still, including grapes and small apples I bought him and unhealthier sweet things. His mobility has declined for whatever reason, and he doesn't seem to be walking much at all, not even with the zimmer frame and not even from bed to chair and back again. (Nurses seem to be using a hoist.) Question: have any of you witnessed these symptoms but then seen an improvement - better appetite/better mobility? Or is this evidence of further gradual decline?
