It's brilliant that she is doing so well.
I don't know anything about the treatment you mention- what is it?
It's such an awful disease- I always remember Nancy Reagan saying it's like a 'long goodbye'.Very very sad.
My husband lives in fear of it or anything similar as his maternal grandmother had
senile dementia.(All these different terms are very confusing!)

I hope the Alumin goes on helping your mum in law for a long while yet.
