hello my husband has vascular dementia and has being feeling dizzy for a while he has tablets for it which are the only ones for dizziness. this has quite quickly got worse to a point when he stands up he feels like falling and when he lays down in bed he feels he is falling through a black hole. he keeps saying it started with his mini stroke but im not sure. he getting really anxious about all day as to what he going to be like when he lays down in bed. i stayed with him until he laid down last night. he has spoken to gp and there isnt anything else they can give him. he has got worse and im wondering is this part of the dementia getting worse or another symptom of something else. as anyone else experienced this?
