Thank you for posting this, Starsky. Had seen some of Teepa Snow's material before, but not this presentation which pulls it all together.
One point which doesn't often get made, but is probably worth mentioning to folks who are just learning about it, is that Alzheimer's is effectively not just "one disease," but a number of variants under one umbrella. Any list of symptoms will likely not apply uniformly to everyone with the disease, and the progression of the stages can vary significantly - part of why it is so difficult to predict timeline and staging. Can recall reading a comment by a medical professional to the effect that "when we eventually understand Alzheimer's, decades down the road, we'll probably find that it's not one disease, but twenty different diseases."
A few other resources which folks might find useful:
Thoughtful Dementia Care: Understanding the Dementia ExperienceProbably one of the best descriptions of what dementia is like from the perspective of the person who has the difficulties. Very instrumental in changing one's understanding from "they're basically normal and certain tools + effort can help them live normally" to a different perspective in which one "gets it" - i.e. understands viscerally the limitations in the person's abilities and cognition, and can adjust communication style to help them feel comfortable, and adjust perspective to achieve the most empathy.
The Selfish Pig's Guide to CaringThe humorous title partly refers to the fact that, to be a good caregiver, one also has to take care of oneself. Humor aside, though, this is a book by a caregiver who thoroughly "gets it" and has experienced all the difficulties involved.
Finally, the
Alzheimer's Association in many, maybe all, regions offers free "Care Consultations." These are appointments one can book and use as wide-ranging conversations to cover whatever topics would be most helpful - medical, legal, financial, etc. - in consultation with a member of the association who has experience in advising on these topics.
