With a family history of Alzheimers in the family, this is a subject that I have been following.
There is a growing argument that the progression of Alzheimers can be halted and cognitive function even improved by the use of a highly nutritious ketogenic diet, combined with a number of lifestyle changes (e.g. puzzles, mental challenges and physical exercise and specific supplements).
I consider it most unfortunate that the UK Alzheimers Society are still regurgitating the standard soundbites and not supporting anything that could give their members and their members' families hope.
Anyone wishing to read more about treating Alzheimers with a ketogenic diet can do so by reading Amy Berger's book on the subject, and look into Dr Dale Bredesen's book The End of Alzheimers. He has been treating patients in this way for a good few years, but gets no support from orthodox medical thinking.
Since Alzheimers and other forms of brain fog, memory problems and Dementia's are more prevalent amongst people with diabetes than in the wider population, I would suggest it is a subject that many members on this forum may find interesting. Especially if they have a family history of Dementia.
