🧪 Overview
The same signal may be beneficial early and damaging late. Testing protective chromatin remodeling with single-cell methylome tracking should reveal a disease-stage interaction and define when intervention is protective versus counterproductive.

🔮 Falsifiable Predictions (2)

IF protective chromatin remodeling defines the therapeutic window, THEN enhancing the remodeling program before stress will improve neuronal survival by >=20%, whereas the same enhancement after injury onset will improve survival by <5%.
Predicted outcome: Pre-stress enhancement yields >=20% survival benefit and post-injury enhancement yields <5% benefit.
Falsification: Timing does not modify response or late enhancement is equally protective.
pendingconf 49%
IF the remodeling is protective rather than pathological, THEN individuals with higher baseline protective chromatin signatures will show >=15% slower NfL increase over 2 years despite comparable baseline pathology.
Predicted outcome: Top-quartile protective signature predicts >=15% lower annual plasma NfL slope than bottom quartile.
Falsification: NfL slopes differ by <5% or top-quartile participants decline faster.
