Understanding APOE4 and Alzheimer’s Risk
APOE4 is the strongest genetic risk factor for Alzheimer’s disease – but it is not a diagnosis, and it is not a fixed outcome. APOE status is determined primarily by two SNPs (genetic markers): rs429358 and rs7412. In most direct-to-consumer genetic reports, APOE4/4 corresponds to rs429358 C/C and rs7412 C/C.
- If you’ve found your way here, you’re likely asking the same questions I am:
What actually moves the needle in Alzheimer’s prevention – especially with APOE4?
This publication is where I explore that question in depth.
I don’t approach this as a fixed protocol or a one-size-fits-all plan.
Instead, I focus on the intersections that seem to matter most:
- Lipid biology and cholesterol transport
- Brain energy and mitochondrial function
- Inflammation, infections, and immune response
- Nutrients, peptides, and emerging interventions
All through the lens of APOE4 and Alzheimer’s risk – and how these systems behave differently when you carry it.
I carry two copies of APOE4.
What began as a wake-up call has turned into an ongoing process of learning, testing, and refining – drawing from both research and my own data.
Here, you’ll find:
- Deep dives into specific mechanisms
- Analysis of research – and where it may fall short
- Practical considerations without oversimplification
- Evolving perspectives as new information emerges
This is where I think things through, connect dots, and share what I’m seeing.
If you’re navigating APOE4 – or simply thinking more seriously about brain health – you’re in the right place.
