For what its worth I am reading up on diet and have PSP on my mind as I read.
There have been some quite astonishing studies post 1940's showing that cutting out certain foods or managing ones diet can substantially change the risk of developing a disease and in some cases can cure a disease.
So there are instances of people adopting a raw veg. diet recovering from bowel or stomach cancer and others of people changing their diet and coming off injected insulin after 20 years of injecting. The average time in that study was 16 days after a change in their diet!
I have only just started reading up on this and I am sticking to those authors basing their work on Journal published research and who also cite references. No quackery, but the medical science people are for ever changing their opinions too.
Anyone interested in this might like to watch this very long talk by Dr Michael Greger
nutritionfacts.org/video/ho...
His website has more illness focused videos and I will be looking for anything on Parkinsons and Alzheimer's which have some relationship to PSP / CBD.
Dr Michael Mosley is also fairly sound, I am reading his book Clever Guts at the moment - Unlike Greger he does not take an illness approach, but similarly focuses on the centrality of the gut and the microbes as a major cause of illness and well being.
(Our guts have as many neurones as a cat has in its brain.)
I doubt there will be a cure in any of this, but there may be some dietary changes which might help. And, yes, Turmeric does raise its head.
Well, it keeps me off the street and out of trouble.
Best
