Could someone tell me what kind of timescale I'm looking at? Is Vascular Dementia very different from AD in the way things progress? I know it probably sounds insensitive, but it's just one of very many questions that keep running through my head. A very good friend of mine's husband passed away with AD 8 years ago, after suffering for about 4 years. Am I looking at a similar decline with my Mum and her vascular dementia? Thanks so much.
