A Scientific-Backed Discussion on Fighting Cognitive Decline (Optispan Podcast)
Whoās on: Matt Kaeberlein with Dr. Kevin White (MD) and Erik Nelson (RN). Published: Sept 2, 2025. Runtime: ~1:24:46. Listen Notes
Executive summary
- The guests argue cognitive decline isnāt inevitable and outline a multi-modal, staged program aimed at haltingāor in some cases reversingādecline. Optispan
- Early detection is central: genetics (e.g., APOE), blood biomarkers, cognitive testing, and imaging are combined to profile risk before symptoms emerge. A case of a 63-year-old APOE4 carrier illustrates this preventative approach. Optispan
- The plan emphasizes a tiered framework: lifestyle foundations ā core supplements ā targeted medications ā carefully selected experimental/adjunct options, with personalization and longitudinal tracking. Optispan
- Lifestyle ābrain armorā (sleep, diet, exercise, metabolic health) is positioned as the base layer for everyone. Apple Podcasts
- Core supplements discussed include omega-3s, B-vitamins, magnesium, and creatine; these are framed as supportive, not cures. Optispan
- Medications considered for specific phenotypes: statins, SGLT2 inhibitors, metformin, with interest in rapamycin and PDE5 inhibitors based on emerging evidence. Optispan
- Experimental/adjunct ideas (for select cases): therapeutic plasma exchange; caution around peptides and stem cells; strong emphasis on ongoing measurement to confirm benefit. Optispan
- Optispan plans an initial pilot cohort (~100 participants) using this program in the coming months. Optispan

AI Summary of the above video:
Note: (Iām less and less happy with these AI summaries, Youtube seems to be blocking all AIs from the transcripts of the videos now, as they donāt want people just reading summariesā¦ Someone needs to come up with an AI agent that will bypass these guardrails that these companies are setting up. Once Iāve started using AI summaries instead of actually watching these long podcast videos, I donāt want to go back.
Introduction to Brain Health Program
- The podcast episode features Eric Nelson from Human Sync and Dr. Kevin White from Prime Health Associates discussing a collaborative program focused on brain health and cognitive decline.
- The program aims to address issues related to dementia and traumatic brain injury, emphasizing lifestyle factors and the potential of advanced diagnostics and therapies.
- Listeners are encouraged to explore the conversation for insights on whether dementia can be prevented or reversed.
Personal Experiences with Brain Health
- Eric shares his background as an ICU nurse at Mayo Clinic and his fascination with the brain, stemming from his fatherās career as a neurosurgeon.
- He recounts his experiences with concussions during high school football, highlighting the lasting impact on his understanding of brain health.
- The conversation shifts to the importance of recognizing the overlap between traumatic brain injuries and the progression of dementia, suggesting that interventions may benefit both groups.
The Importance of Lifestyle Factors
- The discussion emphasizes the significance of lifestyle choices in maintaining brain health and mitigating risks associated with cognitive decline.
- Factors such as diet, exercise, sleep, and stress management are highlighted as critical components of a comprehensive brain health strategy.
- There is a belief that proactive measures can halt or even reverse cognitive decline if taken early enough.
Developing the Brain Health Protocol
- The team is working on finalizing a protocol that incorporates their collective knowledge on brain health, genetics, and aging processes.
- The protocol aims to be personalized, addressing individual needs based on genetic predispositions and lifestyle factors.
- They anticipate rolling out the program to clients in the near future, with a focus on documenting changes in cognitive function and biomarkers.
Case Studies and Personal Stories
- Eric shares a case study of a 63-year-old woman with a genetic predisposition to Alzheimerās, highlighting the importance of early detection and intervention.
- The case study emphasizes the use of advanced diagnostics to assess plaque development and cellular health in the brain.
- The goal for this individual is to maintain her current cognitive function and prevent further decline through targeted interventions.
Diagnostics and Assessments
- The program incorporates comprehensive diagnostics, including genetic testing, blood panels, and imaging to evaluate brain health.
- Key biomarkers such as APOE status, inflammation markers, and neurofilament light are monitored to assess risk and progression of cognitive decline.
- The importance of tracking changes over time through cognitive assessments and imaging is emphasized to evaluate the effectiveness of the interventions.
Potential Therapeutic Interventions
- The conversation explores various therapeutic options, including lifestyle modifications, supplements, and medications that may aid in cognitive health.
- There is a focus on the potential benefits of pharmacological interventions, such as GLP-1 agonists and rapamycin, particularly for individuals at high risk for dementia.
- The discussion also touches on the role of therapeutic plasma exchange and its potential to reduce circulating toxins and inflammation in the brain.
Conclusion and Future Directions
- The episode concludes with excitement about the upcoming launch of the brain health program, which aims to combine various interventions tailored to individual needs.
- The team is committed to ongoing research and adaptation of the protocol based on emerging evidence and patient feedback.
- Listeners are encouraged to stay informed about developments in brain health and the potential for significant improvements in cognitive function through proactive measures.

Yes the gut - brain axis is quite important, and just like the GLP-1 agents seeming to decrease rate of AD, despite not getting into the brain, but having powerful effects on the brain, the diet is another example. Both the Lancet and Finger studies addressing lifestyle and AD indicate powerful effects at mitigating risk with dietary patterns with plant diversity, fiber, polyphenols/flavinoids.
Inulin is not my favorite way of doing it ā e.g. Iād not recommend everyone go out and grab some ā¦ it is a high FODMAP supplement and some people get some solid GI upset. But yes, goaling for 30 grams of fiber (at least) daily, preferably through high quality foods would be my strategy.

I make my own reuteri yogurt using huge amounts of inulin, and Iām also sensitive to many FODMAP foods - reuteri yogurt definitely helps my gut in all sorts of ways. I guess by the time the fermentation is done, over 36 hours, not that much remains. I probably use about 1 cup of inulin to every 1.5 litres of semi-skimmed milk. @DrFraser What is your concern with inulin?

No concern with inulin, apart from it will result in some people getting bloating, AND in practice, Iād want people getting their fiber primarily through diet with whole food plant based forms that are high in nutrients. Inulin is something I do recommend often with chicory root and DGL Licorice ā¦ for gut health along with high fiber from foods. As fiber should be the primary food source for gut bacteria, having some diversity is good. So adding inulin is absolutely fine, if it doesnāt cause side effects, but having that as the primary source of fiber would lose the diversity which I like to see to have a healthy microbiome.

Thatās thanks to an MRI technique called quantitative susceptibility mapping (QSM), which can measure tissue susceptibility and detect subtle variances in iron levels throughout different regions of the mind.
In recent years, iron overload has caught the attention of experts due to its ability to induce oxidative stress. This can contribute to cognitive decline by aggravating amyloid toxicity and promoting cell death. The ability to quantify iron levels via imaging could help identify patients who may be vulnerable to cognitive decline in the future, even before they display symptoms.
āElevated brain iron is a potential marker for neurodegeneration, but its role in predicting onset of mild cognitive impairment (MCI) and prospective cognitive trajectories remains unclear,ā Xu Li, PhD, associate professor of radiology at Johns Hopkins University, and colleagues wrote in RSNAās flagship journal Radiology .
