My friend's mom had it and one of her symptoms was repeating the same question many times a day.
I had read about Curcumin and virgin coconut oil helping with Alzheimer's. He started giving it to her and quickly she seemed to be more "here" and quit repeating questions. She eventually got worse, of, course, but it seemed to stave off the progression for a while.
All anecdotal, but worth a try. Look it up.
I have used Coconut oil for cooking and coconut past as a substitute for butter....Have Turmeric-Curcumin capsules...and Cumin capsules on order.
Use a lot of Curry powder in stews.
