So sorry to hear of your sisters psp! My mom was 76 when diagnosed last year, which makes the prognosis even less predictable than for someone like your sister who is diagnosed at the more common age. She definitely sounds early stage to me. My mom has progressed quickly (after fall resulting in brain bleed/concussion in April) and is now incontinent, virtually incapable of communication (cannot write or speak and barely able to respond with thumbs up/down), has sometimes severe (if understable given the frustration) anger/outbursts or crying, and is very, very slow/rigid and often has bad back pain. But we did spend the 6months after diagnosis (she had symptoms for up to two years prior) going to shows, out for meals and generally taking advantage of life - and I'm super grateful we did that! Are you her primary support or are there others involved in helping? I wish you serenity and an ability to appreciate the memories you're still able to make with her. the alternative isn't better, right? Hang in there.
