What is Alzheimer's?
Alzheimer's
Alzheimer’s disease is a progressive neurodegenerative disorder characterized by cognitive decline, often associated with amyloid-beta plaques, tau tangles, and mitochondrial dysfunction. The material tracks debates about its causes, including the amyloid hypothesis, vascular factors, and mitochondrial dysfunction, as well as potential interventions like creatine supplementation.
How it developed
- Jun 2026 - Darren Candow cited a landmark study of 20 Alzheimer’s patients where 20 grams of creatine daily for 8 weeks increased brain creatine levels by 11% and significantly improved cognitive test scores.
- Jul 2026 - Martin Picard argued that the amyloid hypothesis is not the full truth, noting that some people in their 60s–80s have zero protein deposits yet still have full-blown dementia, based on neuroimaging.
- Jul 2026 - Martin Picard described Alzheimer’s as “type three diabetes,” explaining that when the brain becomes sick, it burns less energy and has difficulty getting glucose inside.
- Jul 2026 - Tim Ferriss expressed skepticism about the “remove amyloid beta and tau tangles and all will be well” hypothesis, which many therapeutics rely on.
- Jul 2026 - Tim Ferriss suggested that much of Alzheimer’s is vascular dementia and some is mitochondrial dysfunction.
In the evidence
Every line below is attributed to a named speaker.
People can have zero amyloid protein deposits in the brain and still present with full-blown Alzheimer's and dementia, undermining the amyloid plaque hypothesis as the primary cause.
“That is not the truth. And what is more true is and let me just say why it's not the truth. You can have people in their 60s and their 70s and their 80s zero protein deposit in the brain. We can image this now pretty well with neuroiming. You can have people zero protein deposit in the brain and they have full-blown Alzheimer's and dementia.”Martin Picard · 2 Jul 2026
Nutrition scientists put an optimal daily fiber target at 40g, above the current UK guideline of 30g, with evidence of continued benefit up to 50g and beyond.
“Latest science is suggesting actually if you go up to 40 grams you get even more health benefits and probably if you keep going to 50 and beyond and those benefits are like living longer and pushing out all of these terrible diseases including cancer and Alzheimer's.”Tim Spector · 30 Jul 2026
Alzheimer's and dementia framed as disorders of increased energy resistance in the brain, with the brain burning less energy and struggling to absorb glucose as symptoms appear.
“Type three diabetes comes from the fact that when the brain gets sick, right? And symptoms of dementia start to appear like loss of memory and mood and depression and that constellation of symptoms. When you look in the brain, it's burning less energy, but it's also harder for glucose to get inside the brain.”Martin Picard · 2 Jul 2026
A landmark study of 20 Alzheimer's patients taking 20 grams of creatine daily for 8 weeks increased brain creatine levels by 11% and significantly improved cognitive test scores.

Tim Ferriss argues the amyloid beta clearance hypothesis for Alzheimer's is wrong, pointing instead to vascular dementia and mitochondrial dysfunction as the real drivers.
“The remove amalloid beta and towangles and all will be well hypothesis which a lot of therapeutics are predicated on. I really don't buy it.”Tim Ferriss · 29 Jul 2026
Tim Ferriss frames Alzheimer's risk as primarily driven by vascular dementia and mitochondrial dysfunction rather than amyloid beta accumulation, undercutting the basis of most current therapeutics.
“I think a lot of it is vascular dementia and some of it certainly is mitochondrial dysfunction.”Tim Ferriss · 29 Jul 2026
