⚖️ Evidence Matrix5 supports5 contradicts
Supports
Hub regions connected by long-range white matter tracts that are particularly vulnerable
Supports
Clemastine promotes OPC differentiation and remyelination in cuprizone and EAE models
Supports
Network-level changes include reduced white matter integrity measurable by diffusion MRI
Contradicts
Myelin changes in AD may be secondary to axonal degeneration - primary vs secondary unresolved
Contradicts
White matter hyperintensities correlate with vascular pathology, not primary OPC dysfunction
Contradicts
Clemastine not advanced to AD clinical trials - off-target antihistamine effects
Contradicts
Siponimod failed in secondary progressive MS - S1P modulation insufficient for established myelin pathology
Contradicts
Aged human OPCs have substantially reduced differentiation capacity vs young animals
