abstract = {Using PET imaging in a group of patients with Alzheimer's
disease (AD), we investigated whether level of education, a
proxy for resilience, mitigates the harmful impact of tau
pathology on neuronal function.We included 38 patients with
mild-to-moderate AD (mean age 67 ± 7 years, mean MMSE
score 24 ± 4, mean years of education 14 ± 4; 20
men, 18 women) in whom a [18F]AV-1451 scan (a measure of tau
pathology) and an [18F]FDG scan (a measure of neuronal
function) were available. The preprocessed PET scans were
z-transformed using templates for [18F]AV-1451 and [18F]FDG
from healthy controls, and subsequently thresholded at a
z-score of ≥3.0, representing an one-tailed p value of
0.001. Next, three volumes were computed in each patient:
the tau-specific volume (tau pathology without neuronal
dysfunction), the FDG-specific volume (neuronal dysfunction
without tau pathology), and the overlap volume (tau
pathology and neuronal dysfunction). Mean z-scores and
volumes were extracted and used as dependent variables in
regression analysis with years of education as predictor,
and age and MMSE score as covariates.Years of education were
positively associated with tau-specific volume
(β = 0.362, p = 0.022), suggesting a lower impact
of tau pathology on neuronal function in patients with
higher levels of education. Concomitantly, level of
education was positively related to tau burden in the
overlap volume (β = 0.303, p = 0.036) implying that
with higher levels of education more tau pathology is
necessary to induce neuronal dysfunction.In patients with
higher levels of education, tau pathology is less paralleled
by regional and remote neuronal dysfunction. The data
suggest that early life-time factors such as level of
education support resilience mechanisms, which ameliorate
AD-related effects later in life.},
