Neurodegenerative CSF markers in genetic and sporadic PD: Classification and prediction in a longitudinal study

PD patients present with disease-specific CSF profiles of Aβ1-42, t-Tau and p-Tau arguing in favor of an involvement of these proteins in PD pathogenesis in both sporadic and genetic forms. Moreover, we found first hints for differences in these CSF profiles between genetically determined PD cohorts but that CSF constellations which tend to predict aspects of disease progression such as cognitive decline seem similar across subgroups of PD.
