The Alzheimer's Drug With a 25% Brain Bleed Risk - Dr. David Perlmutter | TUH #306

About this video

Brecka interviews neurologist Dr. David Perlmutter, author of Grain Brain, about Alzheimer’s as what Perlmutter calls a neurometabolic condition. Perlmutter argues insulin resistance and high blood sugar are central risk factors that can precede cognitive decline by many years, criticises amyloid-targeting Alzheimer’s drugs for what he presents as poor risk-benefit, and makes the case for earlier lifestyle intervention, community and purpose. Brecka connects the discussion to his own mother’s prediabetes history. Note: the transcript provided is a Dutch-language dub.

Key takeaways

• Perlmutter claims insulin resistance and elevated blood sugar are major, early drivers of cognitive decline
• Perlmutter argues Alzheimer’s patients may lose access to memory rather than memory itself
• He states current amyloid drugs carry serious risks with limited benefit, in his assessment
• Perlmutter argues lifestyle intervention is most powerful when started early
