Slightly better day today, mum has had constant stuffy nose for months and found something which she feels is helping today. I'm still not sure if it's physical irritation or her dementia or maybe a mixture of both. She has been seen by GP twice and there is no sign of anything physical such as swelling or blockage by polyps. Her taste has diminished over the Last few years and again it could be the dementia or medication. It's a shame as she doesn't enjoy meals so much, although it can vary from day to day. Also has gone off food she previously considered her favourites. Has anyone else had experience of these things?
