Description
The abstract mentions both neuroinflammation (GFAP, TSPO-PET) and neurodegeneration (NFL, brain-derived tau) biomarkers provide insights into disease progression, but the mechanistic relationship between these processes remains unclear. This gap limits understanding of disease pathophysiology and biomarker interpretation.
