@crazy-daisy, great article and thanks for sharing it.
Did you know that Cannabis can be used for treating Alzheimer's? See the following article The Effects of Medical Marijuana on Alzheimer’s Treatment.

It states:

The Effects of Medical Marijuana on Alzheimer’s Prevention
A preclinical study published in the Journal of Alzheimer’s Disease found that very small doses of tetrahydrocannabinol (THC), a chemical found in marijuana, can slow the production of beta-amyloid proteins, thought to be a hallmark characteristic and key contributor to the progression of Alzheimer’s.

I follow the medical Cannabis sector and while I am not a doctor, over the last few years I have learned quite a bit about using cannabis for various medical ailments. I know this may be controversial, but anyone with Alzheimer's may want to investigate this further as an option for treatment.
