abstract = {Traditional pen-and-paper neuropsychological assessments
are not sensitive to subtle cognitive changes in the
earliest stages of Alzheimer's disease (AD), limiting their
use for monitoring of cognitive performance over shorter
timeframes. Here, we show that frequently administered
remote and unsupervised digital cognitive assessments are
better suited to capture short-term cognitive decline in
early AD.We investigated episodic memory trajectories using
self-administered remote digital testing in 202 participants
(52-85 years) who completed unsupervised tests for at least
30 weeks. Linear mixed modeling was used to investigate main
effects of cognitive status, n = 152 cognitively unimpaired
(CU), n = 50 with mild cognitive impairment (MCI), and
interaction effects of cognitive status by time spent in the
study. Analyses were repeated, stratifying the MCI group by
amyloid-β (Aβ) burden (n Aβ- = 21, n Aβ+ = 24). Baseline
and change-change associations with in-person
neuropsychological assessments were also examined using
Pearson correlations.At baseline, MCI performed worse than
CU on an associative memory task (Object-in-Room Recall,
ORR), memory precision tasks for objects and scenes
(Mnemonic Discrimination Task for Objects and Scenes,
MDT-OS), and a familiarity-based memory task (Complex Scene
Recognition, CSR). A short-term decline in the
familiarity-dependent task was observed in all patients with
an MCI diagnosis, while both the familiarity-dependent
memory task and memory precision for objects task were
sensitive to decline in the MCI Aβ+ group specifically.
Change in the remotely assessed familiarity-dependent memory
was correlated with multi-year change on annual in-person
neuropsychological assessments. Finally, in-person tests
were not sensitive to short-term cognitive changes in
MCI.Altogether, these findings show that frequent remote
cognitive testing is a promising tool to feasibly capture
subtle and short-term cognitive decline.},
