2	What is the optimal sampling frequency for CSF lactate/pyruvate ratios to detec… While CSF lactate/pyruvate dynamics were identified as promising biomarkers, the debate didn't resolve the temporal kinetics needed to distinguish therapeutic r… gap-debate-20260410-111950-1fac0d81	open	0.780	biomarker development	2026-04-10	Open →
3	How can metabolomic biomarkers overcome participant heterogeneity to achieve di… The authors explicitly note participant heterogeneity as a major limitation affecting metabolomic marker reliability. Resolving this methodological challenge is… gap-pubmed-20260410-184221-965b3979	open	0.760	biomarker development	2026-04-10	Open →
4	What biomarkers can reliably measure real-time glymphatic function to guide sle… The debate emphasized the need for precision timing and monitoring of glymphatic clearance, but no validated biomarkers for real-time assessment were identified… gap-debate-20260410-111124-00bd9682	open	0.750	biomarker development	2026-04-10	Open →
5	Why does p-tau181 show superior freeze-thaw stability compared to amyloid pepti… The abstract reports higher stability of p-tau181 to repeated freezing-thaw cycles compared to Aβ species, but provides no mechanistic explanation.
