Summary

In this episode of the Root Cause Medicine Podcast, Dr. Kate Kresge sits down with neurologist and bestselling author Dr. Dale Bredesen to challenge everything we think we know about brain aging. Dr. Bredesen shares why age-related cognitive decline is not just treatable but in many cases preventable—and even reversible. Drawing on decades of lab research and clinical success, he outlines the root causes of cognitive decline and introduces the listener to the "cognoscopy," a powerful tool for early detection. With practical, science-backed insights on inflammation, insulin resistance, environmental toxins, and the emerging brain microbiome, this is a masterclass in 21st-century brain health. You’ll here them discuss: - Why cognitive decline is often preventable—and sometimes reversible - The three key drivers of cognitive decline: inflammation, energy deficit, and toxicity - How to use the "cognoscopy" to catch signs of dementia early - The role of the brain’s microbiome and oral health in neurodegeneration - Why mold, metals, and mycotoxins are underestimated threats - New blood biomarkers like pTau217, GFAP, and NFL - Supplements that support brain health, including magnesium threonate and omega-3s - How to tailor treatment using functional lab testing and wearables - Stories of patient recovery—and what makes the difference Order tests through Rupa Health, the BEST place to order functional medicine lab tests from 30+ labs - https://www.rupahealth.com/reference-guide

0:00.0	Well, hello there. Welcome to the Rukauze Medicine podcast. I'm your host for today, Dr. Kate Kreske, and we're asking a radical question.
0:06.7	What if cognitive decline could be caught early and even reversed with the right tests?
0:11.4	Joining me today is neurologist and Alzheimer's researcher Dr. Dale Bredesen, a pioneer in precision brain health.
0:17.2	His work has redefined how we think about memory loss, not as a mysterious inevitability, but as a condition with measurable and actionable biomarkers. In this episode,
0:26.2	we're diving into what he calls the cognoscopy, a brain health screening that he recommends
0:30.6	everyone should have routinely at 45, just like they would have a colonoscopy. You'll learn
0:35.2	about cutting-edge biomark like Ptale 217,
0:38.5	GFAP, and neurofilament light or NFL,
0:41.2	alongside tools that assess inflammation,
0:43.7	insulin resistance, toxin exposure,
0:45.5	and even the brain's microbiome.
0:47.3	We're gonna cover the earliest warning signs
0:49.3	that conventional medicine misses
0:50.7	when it comes to cognitive decline.
0:52.2	How to match biomarkers with personalized interventions,
0:55.0	the science behind supplements like magnesium 3 and 8 glutathione and phosphatidylcholine when it comes
0:59.9	to brain health, and why oral health and even mold exposure could show up in your labs
1:04.2	before you feel any symptoms related to cognitive health. Dr. Bredison says with the right tools,
1:09.4	food, sleep, detox testing, we can match brain span
1:12.7	to lifespan, meaning that you can live into your older years thriving, both in your mind and your
1:18.9	body. Alzheimer's is not inevitable. If you're a practitioner looking to lead the future of
1:23.5	neurodegenerative care or simply someone who's invested in cognitive longevity, this
	...
