CSF synaptic biomarkers in the preclinical stage of Alzheimer's disease and their association with MRI and PET markers of neurodegeneration: a cross-sectional study
<p>Objective: To determine whether CSF synaptic biomarkers are altered in the early preclinical stage of the Alzheimer's <i>continuum</i> and associated with Alzheimer's disease (AD) risk factors, primary pathology, and neurodegeneration markers.</p> <p>Methods: Cross-sectional study in the ALFA+ cohort, comprising middle-aged cognitively unimpaired participants. CSF neurogranin and GAP-43 were measured using immunoassays and SNAP-25 and synaptotagmin-1 using immunoprecipitation mass spectrometry. AD CSF biomarkers Aβ42/40, p-tau and t-tau, and the neurodegeneration biomarker NfL were also measured. Participants underwent structural MRI, and <span>fluorodeoxyglucose and</span> Aβ<span> PET imaging. General linear modeling was used to test the associations between CSF synaptic biomarkers and risk factors, </span>Aβ<span> pathology, tau pathology, and neurodegeneration markers.</span></p> <p>Results: All CSF synaptic biomarkers increased with age. CSF neurogranin was higher in females, while CSF SNAP-25 was higher in <i>APOE-</i>ε4 carriers. All CSF synaptic biomarkers increased with higher Aβ load (as measured by CSF Aβ42/40 and Aβ PET Centiloid values) and, importantly, the synaptic biomarkers were increased even in individuals in the earliest stages of Aβ deposition. Higher CSF synaptic biomarkers were also associated with higher CSF p-tau and NfL. Higher CSF neurogranin and GAP-43 were significantly associated with higher brain metabolism, but lower cortical thickness in AD-related brain regions.</p> <p>Conclusion: CSF synaptic biomarkers increase in early preclinical stages of the Alzheimer's <i>continuum </i>even when a low burden of Aβ pathology is present, and they differ in their association with age, sex, <i>APOE-</i>ε4<i>,</i> and markers of neurodegeneration.</p>
