Danny...........i am not an expert by no means, but with what i have seen and experienced i personally believe that this can be true somewhat.
Comparing Brian with some of the patients at my Nursing home that i work at i can see a REAL notable difference.
Brian is stimulated at home with all that goes on around him....children, dogs, visitors, comings and goings etc Plus going to a stimulating Alz centre three times a week for word games, puzzles, and other programmes set up especially for dementia persons.
On the other hand this person i work with has NO visitors, no stimulating programmes, plus he is on quite a large dose of meds to keep him from wondering or getting agitated with other residents or the staff. His routine is only the meals.....and then he has to be let know if he is in his room and prompted on where to go. He has a walking frame to balance on as the drugs have made him very unstable.
But then again in saying this even though Brian has been here for 4 years now with us i STILL see a decline which i think may be due to the drugs. Even though we choose to have him on a lower dose then prescribed as i would rather he be alert to toilet himself. He also has facial movement habits from the drugs......and hanging his tongue out.
Really it is different per person. I just attended a dementia work shop the other day and learnt that the frontal lobe damage causes some problems that i have noticed in Brian that may not have anything to do with the WKS?? I am wondering if he has had any damage to his frontal lobe from the drugs or if it is just a deteriation of the WKS?? These questions i would love answered also BUT no one seems to know.
Good luck with any other advice that you receive........we are all learning as we go.
