🧵 2/3 They bind tau differently. MK-6240 was always one step ahead, by 20 to 30 centiloids, roughly 3 to 5 years sooner. A 10-year study found cortical thickness can briefly rise before it declines, so a scan can read reassuring at the wrong time (Qiu, IND 2025).

Flame hero stat slide. Big number 47 percent agreement between the two FDA-approved tau tracers.

Light slide. The biphasic trap: cortical thickness can rise before it falls, so an early scan can look falsely reassuring.

Light slide. What to actually do: ask which tracer, consider a p-tau217 blood test, and a standard MRI first.

🧵 1/3 Two FDA-approved tau brain scans, same patient, same tau, disagree almost half the time. MK-6240 and Flortaucipir agreed only 47% of the time, on the same brains (Rocha, IND conf 2025). The less sensitive one can read fine while tau builds.

🧵 2/3 Inside that responder subgroup, the effect was ~2x what today's approved Alzheimer's drugs achieve (Liu, AAIC 2025). Carriers and non-carriers can react very differently. Trials for one genetic profile could run 60 to 70% smaller.

Light stat slide: the hidden responders had a treatment effect roughly double what approved drugs achieve.

Navy content slide: why one average hides carriers, because carriers and non-carriers can respond very differently to the same molecule.

🧵 1/3 A drug got called a failure. Then researchers reran the numbers: 43% of patients had actually improved, buried under everyone else's average. A Washington University team re-read old data with machine learning to find them (Liu, AAIC 2025).

🧵 1/3 95% stick with their protocol when they do one thing. Most people quit not from laziness, but because nothing holds them to it. With APOE4, consistency isn't optional. Alone: a plan, then silence. The loop: a clear goal, check-ins, peers who get it.

🧵 2/2 Step 3: change one variable at a time, an n-of-1 approach (McDonald & Nikles 2021). Step 4: measure both ways, bloodwork plus how you feel. 536+ carriers do this together, 89% report biomarker gains in 3 months. apoe4.link/fourstep Not medical advice.

🧵 1/2 Stop guessing with your APOE4. There's no one-size-fits-all protocol, random advice can cost you years. Step 1: no-regret moves, movement, Mediterranean eating, sleep, tracking. Step 2: genetics, an MTHFR variant means methylated B vitamins can matter more (Lizer 2011).

🧵 2/3 Mistake 2: treating sleep and stress as optional. Sleep is when the brain clears waste, and stress drives inflammation. Mistake 3: tracking nothing. Without numbers you miss the minimum effective dose that still works.

🧵 1/3 Three quiet mistakes can undo years of effort for carriers, and none feel like mistakes in the moment. Mistake 1: supplements before the foundation. Roughly 80% comes from food, movement and sleep, not the bottle (supplements close the final 20%).

Cover: the 3 quiet mistakes most APOE4 carriers make.

🧵 2/3 Four boxes: keepers (high impact, easy), quick wins (easy, small), big bets (high impact, hard), drop them (low impact, hard). The one question: does it move a number that matters to you? If you can't measure it, you're guessing.

🧵 1/3 You can't do every APOE4 intervention, so stop trying. Most carriers chase everything and move nothing. A cholesterol cut that transforms one carrier's ApoB can barely touch another's. Plot every move on a grid: impact up, effort across.

Cover slide. Navy. Headline: You cannot do every APOE4 intervention. Subtext: here is how to choose the few that actually matter.

Navy sub-hook slide. The problem is not effort, it is that no one taught you to prioritize, so you chase everything and move nothing.

Light slide. Why this is personal: the same intervention can transform one APOE4 carrier and barely touch another, so your protocol has to be yours.

🧵 2/3 Across 75 studies, industry-sponsored research was ~34% more likely to favor the funder's product (Lundh 2017). For carriers: exercise, sleep, nutrition and stress may be our strongest levers, and exactly the ones nobody can patent.

Flame hero stat slide: industry-sponsored studies were about 34% more likely to reach a conclusion that favored the sponsor.

🧵 1/3 Some of the best things for your brain will never get a trial. Not because they don't work, because nobody profits proving it. In one review of trials for one Alzheimer's drug, 17 of 30 studies were industry funded, only 4 independently (Birks & Harvey 2018, Cochrane).
