The most important 20 years of brain health happen before anyone's checking.
A new blood test can find Alzheimer's pathology decades before symptoms. New drugs can clear it from the brain. Real advances but here's the catch: decline continues anyway.
Because amyloid isn't the cause. It's a marker for something upstream that's been running since your fifties.
That "something upstream" is the story worth paying attention to. Metabolism, gut health, immune signaling, sleep, brain networks- all shifting quietly for two decades before a test ever turns positive. That window is where the real opportunity lives, not after a diagnosis.
Full breakdown of what's happening in that window- and what's actually measurable and correctable- is on the blog now. Link in bio.
