Qualy #24 - What are the "ABCs" of Alzheimer's prevention?
This Qualys episode features Richard Isaacson, M.D., discussing the "ABCs" of Alzheimer's prevention, emphasizing a precision medicine approach using detailed anthropometric and blood biomarkers. He advocates for shifting philanthropic funding towards prevention research due to its underfunding and high potential impact compared to treatment.

ABCs of Alzheimer's Prevention Management
This framework outlines key areas for managing Alzheimer's risk. 'A' stands for anthropometric measures, focusing on body fat, lean mass, and visceral fat rather than just weight or BMI. 'B' represents blood-based biomarkers, emphasizing detailed cholesterol profiling and inflammatory markers. 'C' refers to cognitive function, which is assessed as part of a personalized approach.
Deep Dive Cholesterol Profiling
This goes beyond standard lipid panels (LDL, HDL, triglycerides) to include more granular markers like ApoB, LDL-p, and particle subtype. This detailed analysis provides a more comprehensive understanding of an individual's cardiovascular risk, which is closely linked to cognitive health and Alzheimer's prevention.
Precision Medicine Approach for Alzheimer's Prevention
This is a highly personalized strategy that integrates an individual's unique data across various domains, including cholesterol, inflammation, metabolism, nutritional biomarkers, genetics, body fat composition, and cognitive function. The goal is to develop a tailored prevention plan that is more effective and provides positive reinforcement for sustained lifestyle changes.

The 'ABCs' framework for Alzheimer's prevention includes 'A' for anthropometric measures (body fat, lean mass), 'B' for blood-based biomarkers (detailed cholesterol, inflammation), and 'C' for cognitive function, all integrated into a personalized plan.
Beyond standard cholesterol, important biomarkers include ApoB, LDL-p, and particle subtype for a deeper lipid dive. Inflammatory markers like myeloperoxidase, LP-PLA2, fibrinogen, and high-sensitivity CRP (hSCRP) are also checked, with hSCRP often being the most informative.
Current pharmacological research for Alzheimer's disease has a very low success rate; only 0.4% of drugs developed for treatment prove effective, meaning 99.6% are considered failures.
Currently, an estimated 99.9% of Alzheimer's research funding goes to treatment and only 0.1% to prevention. A more balanced approach, such as 90% for treatment and 10% for prevention, is suggested to make a greater impact.
Prevention research is often seen as 'squishier' and faces a bias because it relies on influencing lifestyle behaviors (diet, exercise, sleep), which are harder to change than simply prescribing a pill.
By integrating an individual's specific data on cholesterol, inflammation, metabolism, nutrition biomarkers, genetics, body fat, and cognitive function, a precision medicine plan can be developed, leading to better outcomes and positive reinforcement for sustained behavioral changes.
8 Actionable Insights
1. Prioritize Alzheimer’s Prevention Funding
Advocate for a significant shift in Alzheimer’s research funding towards prevention (e.g., 10-90% prevention-treatment split), acknowledging that current drug development has a 0.4% success rate and prevention offers a much bigger impact.
2. Embrace Lifestyle Changes for Prevention
Prioritize difficult but impactful lifestyle changes like sleep, meditation, exercise, and diet for Alzheimer’s prevention, as evidence suggests these behaviors have a greater effect than solely relying on medication.
3. Personalized Precision Medicine Plan
Seek a personalized precision medicine approach for Alzheimer’s prevention by integrating your individual data on cholesterol, inflammation, metabolism, nutrition biomarkers, genetics, body fat, and cognitive function to create an effective, tailored plan.
4. Deep Dive Body Composition Analysis
For Alzheimer’s prevention, focus on detailed anthropometric analysis beyond just weight and BMI, examining body fat, lean mass, and the location of metabolically active visceral fat.
5. Comprehensive Blood Biomarker Analysis
For Alzheimer’s prevention, get detailed blood-based biomarker profiling, including advanced cholesterol markers (ApoB, LDL-P, particle subtype) and inflammatory markers (high-sensitivity CRP, fibrinogen, myeloperoxidase, LP-PLA2), with hSCRP noted as most informative.
6. Implement High-Intensity Interval Training
To effectively lose weight and body fat, engage in high-intensity interval training (HIIT) instead of only moderate exercise like 20 minutes on an elliptical three times a week, tailoring the approach to your individual biology.
7. Monitor Biomarkers for Progress
Regularly review your biomarkers with your doctor to track how lifestyle changes impact your health, using this feedback for positive reinforcement and to make necessary adjustments to your plan.
8. Utilize Free Prevention Education
Access free online educational resources that provide interactive content on Alzheimer’s prevention to learn and impact your health, as these tools can reach many people while experts are sleeping.

What is the definition of crazy is it throwing more money into the same pile that's taking the same approach to a disease that's not working or is it possibly looking to this novel idea of Alzheimer's prevention.

Prevention suffers from a number of things it's way squishier there's always going to be a bias against the idea that you can get people to change behaviors lifestyle behaviors.
Peter Attia, M.D.
It's not just about weight and BMI like that's just like the worst no it's about body fat where's the fat metabolically active yada yada.

Why is the neurologist knowing all of this stuff when every cardiologist seems to like still be in the dark ages on this that drives me crazy.
