I received my letter today, and very pleased I was to get it. I have only been involved with dementia for two and a half years - since my partner was diagnosed. I support AS in many ways, but one thing just occurred to me reading the letter. I am probably being hugely simplistic, and not at all scientific - but I have a question. In looking to achieve a cure for dementia - is the aim to cure those who are in the early stages, or is the aim to prevent cases of the disease by screening? Am I correct in thinking that people like my partner who have significant brain damage cannot be helped - nothing will ever be able to put right the damage? So in looking for a cure, are the AS in reality thinking that prevention is better than cure?
