Do most people find that their loved ones are given a definitive diagnosis of what type of dementia they have? My mother has had dementia for years and we have variously been told that it is Multi-Infarct and Lewy Bodies. I believe that Lewy Bodies is the most likely cause but this is only through what I have read about the symtoms. Also she has Parkinsons and I believe there can be a link with Lewy Bodies. I have also heard that in most cases it could only be definitely proved by a post-mortem - closing the stable door after the horse has bolted! Would there be any benefit in having a diagnosis? This is my first post so forgive me if I'm asking questions that have been answered many times over! Thanks in advance for any advice anyone can offer.
