abstract = {In functional magnetic resonance imaging (fMRI) studies,
episodic memory is commonly investigated with the subsequent
memory paradigm in which brain activity is recorded during
encoding and analyzed as a function of subsequent
remembering and forgetting. Impaired episodic memory is
common in individuals with or at risk for Alzheimer’s
disease (AD), but only few studies have reported subsequent
memory effects in AD or its risk states like mild cognitive
impairment (MCI). One reason for this might be that
subsequent memory responses may be blunted in AD or MCI and
thus less likely to manifest in fMRI signal differences.
Here, we used Bayesian model selection of single-subject
fMRI general linear models (GLMs) for a visual novelty and
memory encoding experiment to compare the model performance
of categorical and parametric subsequent memory models as
well as memory-invariant models in a clinical cohort (N =
468) comprising healthy controls (HC) as well as individuals
with subjective cognitive decline (SCD), MCI, and AD, plus
healthy relatives of AD patients (AD-rel). We could
replicate the previously reported superiority of parametric
subsequent memory models over categorical models (Soch,
Richter, Schütze, Kizilirmak, Assmann, Knopf, et al., 2021)
in the HC and also in the SCD and AD-rel groups. However,
memory-invariant models outperformed any model assuming
subsequent memory effects in the MCI and AD groups. In the
AD group, we additionally found substantially lower model
preference for models assuming novelty compared to models
not differentiating between novel and familiar stimuli. Our
results suggest that voxel-wise memory-related fMRI activity
patterns in AD and also MCI should be interpreted with
caution and point to the need for additional or alternative
approaches to investigate memory function.},
