Hi sir Alec, thanks for asking about my mother, how's your father? (gosh that sounded odd)
My mother isn't any better, I've found a Cardiologist, who did trials 4 years ago for valve replacement via the Femoral Artery, using a catheter, so we'll see him and take it from there.
I think you're right about this new drug probably only being available to certain people in certain catchment areas. It is a real breakthrough though. Alzheimers is a terrible disease and traumatic for both sufferers and their loved ones.
