abstract = {Associations between longitudinal changes of plasma
biomarkers and cerebral magnetic resonance (MR)-derived
measurements in Alzheimer's disease (AD) remain unclear.In a
study population (n = 127) of healthy older adults and
patients within the AD continuum, we examined associations
between longitudinal plasma amyloid beta 42/40 ratio, tau
phosphorylated at threonine 181 (p-tau181), glial fibrillary
acidic protein (GFAP), neurofilament light chain (NfL), and
7T structural and functional MR imaging and spectroscopy
using linear mixed models.Increases in both p-tau181 and
GFAP showed the strongest associations to 7T MR-derived
measurements, particularly with decreasing parietal cortical
thickness, decreasing connectivity of the salience network,
and increasing neuroinflammation as determined by MR
spectroscopy (MRS) myo-inositol.Both plasma p-tau181 and
GFAP appear to reflect disease progression, as indicated by
7T MR-derived brain changes which are not limited to areas
known to be affected by tau pathology and neuroinflammation
measured by MRS myo-inositol, respectively.This study
leverages high-resolution 7T magnetic resonance (MR) imaging
and MR spectroscopy (MRS) for Alzheimer's disease (AD)
plasma biomarker insights. Tau phosphorylated at threonine
181 (p-tau181) and glial fibrillary acidic protein (GFAP)
showed the largest changes over time, particularly in the AD
group. p-tau181 and GFAP are robust in reflecting 7T
MR-based changes in AD. The strongest associations were for
frontal/parietal MR changes and MRS neuroinflammation.},
