What is Alzheimer's?

Alzheimer’s disease is a neurodegenerative condition characterized by cognitive decline, memory loss, and mood changes, often associated with brain energy deficits and protein deposits. The material tracks debates about its causes, including the amyloid hypothesis, vascular factors, and mitochondrial dysfunction, as well as potential interventions like creatine supplementation.

• 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.
