Sorry, Mern... But I haven't covered much regarding dementia and Alzheimer's. It occasionally comes up when I'm covering primary care stuff -- but more for recognizing it / diagnosing -- not research on causes, etc.
My grandmother has had dementia for 15 years -- slowly progressing to the point she is now, which is very severe. It's devastating to watch. I'm sorry you lost your mom that way.
