Cognitive decline, mood disorders, and persistent neurological symptoms are often treated in isolation, even as underlying drivers like inflammation, infections, and blood flow dysfunction continue to go unaddressed. Emerging research suggests that brain health requires a root cause approach that integrates physiology, environment, and lifestyle over time.

In this episode of Extend, we sit down with Dr. Eboni Cornish, Associate Medical Director at Amen Clinics and President Elect of ILADS, to unpack the science of neural longevity and how brain imaging can reveal hidden drivers of mental health symptoms. We break down how SPECT scans uncover patterns of neuroinflammation, why conditions like ADHD and depression may stem from infections, toxins, or hormonal shifts, and how blood flow and cerebellar function play a central role in cognitive performance and emotional regulation.

We also explore how factors like sleep apnea, perimenopause, chronic infections, and metabolic dysfunction quietly reshape brain activity and how targeted interventions can restore function over time.

Dr. Eboni Cornish is a nationally recognized expert in neuroinflammation and complex chronic illness, integrating advanced biomarker testing with brain imaging to uncover root causes and translate cutting edge science into practical strategies for long term brain and body resilience.

Cholesterol remains one of the most debated biomarkers in cardiovascular medicine, yet many people still misunderstand what it actually tells us about metabolic health and disease risk. As research evolves, the conversation is shifting from simple cholesterol numbers toward deeper drivers of cardiometabolic dysfunction.

In this episode of Extend, we sit down with Nick Norwitz, metabolic health researcher and physician scientist, to unpack the science behind cholesterol, insulin resistance, and cardiovascular risk. We break down the difference between LDL and ApoB, why insulin resistance may be a stronger predictor of heart disease, how statins work beyond cholesterol lowering, and what emerging research reveals about metabolic health, biomarkers, and individualized risk.

We also explore how curiosity driven experimentation, data tracking, and deeper metabolic literacy can help people move beyond simplistic cholesterol narratives and better understand their own cardiometabolic health.

Nick Norwitz is a physician scientist and metabolic health researcher who graduated valedictorian from Dartmouth College before earning a PhD in Human Metabolism from the University of Oxford and an MD from Harvard Medical School. Following a personal battle with inflammatory bowel disease, he became a leading voice in metabolic health education and the author of the widely read newsletter StayCuriousMetabolism.com.

What We Discuss:

• (02:14) The biggest misconception about cholesterol, LDL, and cardiovascular risk

• (06:03) How sleep, inflammation, and plaque formation connect to heart disease

• (08:18) Why insulin resistance may predict cardiovascular risk more strongly than LDL

Chronic symptoms often get labeled, managed, and medicated, yet the root cause can remain hidden. Parasites, mold exposure, Lyme disease, and microbial imbalances may quietly disrupt energy, digestion, immunity, and cognitive clarity for years without being recognized.

In this episode of Extend, we sit down with Kim Rogers, founder of RogersHood Apothecary and creator of the ParaFy Kit, to unpack the hidden role parasites may play in chronic illness and why this topic remains largely absent from conventional medicine. We break down how parasite exposure can occur through water, food, pets, and environmental toxins, why standard testing frequently misses infections, and how symptoms like bloating, brain fog, fatigue, teeth grinding, and insomnia may point toward deeper biological disruption.

We also explore how a structured cleanse protocol using targeted herbs, binders, and supportive detox strategies may help the body remove parasites, heavy metals, and microbial overgrowth while restoring gut balance and energy.

Kim Rogers is a former Western healthcare educator and curriculum author who spent more than two decades working inside the medical system before her own health crisis led her to uncover parasites as a major driver of chronic illness, eventually building a global community and wellness company dedicated to helping people reclaim control of their health.

What We Discuss:

• (01:31) Why parasites are a major blind spot in Western medicine

• (02:32) Kim's health story and what led her to parasites
