Seeing as my mother now has dementia, and her mother did before her, will I get it? My sister? My daughter? Every time I forget something I am getting paranoid. People tell me it's because of the stress/anxiety that my GP has signed me off school with, but I can't help worrying. Mum spent about 10 years asking this same question and being repeatedly told her failing memory was normal - well they were wrong. If it happens to me, I hope there is either a cure, or I can find the strength to take my own life before I am too incapable. How will I know, it seems that you don't get a diagnosis until you no longer are able to understand it.
