... with that all being said, my mother has early onset Alzheimer's disease (hardly over 60), and getting her on any mitigative attempts like elucidated by Bredesen is effectively impossible. She's still independent enough to live and do most things on her own, but injecting new habits has proven really challenging, as apathy is one of the most pervasive symptoms of the disease. She also had years of obstructive sleep apnea that she refused to treat, as she hated the CPAP machine.
Sure, Breseden is likely a bit of a scam artist, and it's very unlikely his protocol reverses the illness as he claims, but his ideas piecemeal are hardly "unproven" as elucidated by folks here. I think it's very unlikely that Alzheimer's finds a "cure" in a pill or some easy treatment--it seems like it's a disease that emerges after years of dysfunction, potentially from many causes, and you can't rebuild Rome overnight. I'd guess that the future of Alzheimer's research will be in prevention.
It's akin to me saying that if you eat one cheeseburger every day for your whole life, you'll not get dementia. Then when you don't get dementia in the next 10 years, say that it shows what I'm saying must have had some validity behind it.
