We explore why Alzheimer’s may begin decades before symptoms appear, the biomarkers that can help identify risk earlier, and the lifestyle and medical factors that may influence cognitive health.We also discuss the role of sleep, insulin resistance, inflammation, toxins, ketones, peptides, stem cells, GLP-1 medications, psychedelics, and neuroplasticity.This conversation offers an important message: the earlier we understand what is driving cognitive decline, the greater the opportunity to act.In this episode, you’ll learn:• Why Alzheimer’s may begin decades before symptoms• What Dr. Bredesen’s latest trial revealed• The stages from prevention to dementia• Blood biomarkers linked to early decline• Insulin resistance, ketones, and brain energy• Sleep apnea and long-term brain health• Why there is no single cureTIMESTAMPS00:00 Introduction03:37 The Alzheimer’s trial where 90% improved06:35 What drives cognitive decline12:01 Why Alzheimer’s is no longer viewed as hopeless16:08 The four stages of cognitive decline18:22 Blood tests that may reveal risk earlier22:22 The key drivers of Alzheimer’s23:36 The seven foundations of brain health25:53 Sleep targets for cognitive longevity28:27 GLP-1s and Alzheimer’s risk31:35 Peptides for brain health35:59 Stem cells, exosomes, and regenerative medicine39:32 Is there hope at every stage?40:45 Inside the randomized clinical trial46:18 Psychedelics and neuroplasticity52:31 Dr. Bredesen’s final messageCONNECT WITH DR.
