Cerebrospinal fluid markers link to synaptic plasticity responses and Alzheimer's disease genetic pathways.

ABSTRACT:

Background

Synapse loss is linked to cognitive symptoms in Alzheimer's Disease (AD) and Cerebrospinal fluid (CSF) synaptic biomarkers may clarify disease heterogeneity and disease mechanisms for progression beyond amyloid (Aβ) and tau pathologies, potentially revealing new drug targets.

Methods

We used a mass-spectrometry panel of 17 synaptic biomarkers including neuronal pentraxins (NPTXs) linked to glutamatergic signaling, and 14-3-3 proteins linked to tau-pathology and synaptic plasticity. Synapse markers were evaluated in two independent cohorts: Dementia Disease Initiation (DDI) (n = 346) and Amsterdam Dementia Cohort (n = 397), both with cognitive assessments up to 10 years. We used linear regression to compare synapse marker differences between CSF-determined Aβ + cog
