My nan had Alzheimers (Dementia) too. Looking back, it was a rather fast process from diagnosis to her passing away.

Modern medicine and other revolutions have overcome so many things in the past. Just throw a look into our history books: People that currently live in civilized parts of the world don't have to suffer from hunger or thirst anymore, big wipeouts like the pest have been defeated, and even modern diseases such as HIV and smaller victories over certain kinds of cancer were put under quarantine (meaning we can live with it).

The thing we gotta keep in mind is: we all still have to die one day! At least, that's how it currently is. Despite who you are, and what you think is keeping you alive for the healthiest and longest possible - we'll still get there one day.

So - it's gotta be SOMETHING that will assist you in this progress. Alzheimers is a relatively new name for something that's been around for a while, but is still considered a new thing.

In my beliefs, once your soul is leaving your physical body, a huge cleanse, and recovering, and remembering takes place. That's the same for everyone. Whether you're being pulled out of your physical body in a quick event (sudden death through accident), or whether you take your time to organize your last days and say goodbye to your loved ones in shape of a disease that takes its time before you die (your soul might have plans you might know nothing about!) "in the end, it all ends the same..." and that makes it the wonderful circle of life. Well, the physical life at least! ;)
