Contradicts
Based primarily on one study which may not generalize broadly
Contradicts
Myelin changes in aging may be adaptive responses rather than purely pathological

🔮 Falsifiable Predictions (2)

IF GAL3ST1 is pharmacologically inhibited in the cuprizone demyelination mouse model, THEN remyelination efficiency will increase (measured by increased MBP+ oligodendrocyte density and improved g-ratio toward 0.8 in remyelinated axons) within 5 weeks of inhibitor administration.
Predicted outcome: ≥30% increase in MBP+ cell density in corpus callosum lesions; g-ratio improvement to 0.75-0.85 range in ≥50% of remyelinated axons
Falsification: No statistically significant change in MBP+ cell density (p>0.05) and no improvement in g-ratio (remains >0.9) compared to vehicle-treated controls

IF human subjects with early-stage Alzheimer's disease (Clinical Dementia Rating 0.5) receive a GAL3ST1-modulating therapy for 6 months, THEN CSF sulfatide levels will increase by ≥25% relative to baseline, and cognitive decline rate will slow (≤0.5 points/year on CDR-SB).
Predicted outcome: CSF sulfatide increase ≥25% from baseline at month 6; annualized CDR-SB change ≤0.5 points
Falsification: CSF sulfatide unchanged or decreased by >10% from baseline; or CDR-SB decline ≥1.0 points/year despite biomarker evidence of target engagement
