Thanks this was exactly what I was looking for. 
I find that there are way too many people with Alzheimer's and way too many family members who are connected to them who seem to have little to zero insight into just how bad things have gotten for their loved one and way too little done in the way of interventions. Sometimes, I just want to say: "How the hell did you not notice it all of these years?"
I also love modern medicine as much as the next person, but the 
studies of medications currently at our disposal are discouraging to say the least and probable minimally helpful in those who have already progressed too far in their decline. Maybe this would make more difference to those who were discovered earlier and willing to be treated earlier?
I have also spoken with this family member about it and offered what little support I had at my disposal, but his ability to outsmart his dwindling 
hippocampus is coming to an end. Other than that, he is extremely self conscious about his eroding short term memory and really refuses to discuss it any further. At some point, his 
short term memory will stop updating his 
long term memory, and his memory bank's last memories of us will be stuck in time forever while we continue to age and look different from the people he remembers. Worse still is the fact that his short term memory might slip to the point that he even lacks insight into how bad his problem really is and that is what i'm really bracing for. 
He fortunately does have someone living with him, but it does come to a point where we all worry about even leaving him in the house alone for a few minutes which is why I've been looking into all of these gadgets to help us all out. Again, I appreciate any and all sorts of discussion about this if anyone has any questions, stories, or discoveries/inventions to share.
