Cerebrospinal fluid YKL-40 (chitinase-3-like protein 1) identifies microglial priming prior to tau or amyloid biomarker changes. Elevated in pre-symptomatic familial AD and increases before detectable neurodegeneration. However, cellular origin ambiguity (produced by astrocytes, microglia, and infiltrating immune cells) and lack of specificity across neurodegenerative diseases remain fundamental limitations.

A weighted combinatorial algorithm combining a priming-associated marker (YKL-40), a microglial activation state marker (sTREM2), and a synaptic vulnerability marker (neurogranin) creates a composite fingerprint for identifying the temporal window before neurodegeneration. The multi-marker approach provides statistical robustness against individual marker limitations, though it inherits component weaknesses and carries overfitting risk requiring rigorous external validation.
