The Rey and Taylor figures, two visual perception and memory tests, are not equivalent in terms of their difficulty. The purpose of this study was to examine factors such as age, gender, order of administration, copy time, and copy score that could account for the variability in recall performance. Copy score was shown to be the best overall predictor of recall. Younger participants recalled more units than older participants on both complex figures. Furthermore, older participants appeared to benefit more from the presentation of the Taylor figure first compared to when they were presented with the Rey figure first. The present findings reveal the importance of test order and provide equations that can be used to facilitate the comparison of scores derived from the two figures in test-retest situations.

Background: Obstructive sleep apnea (OSA) increases risk for cognitive decline and Alzheimer's disease (AD). While the underlying mechanisms remain unclear, hypoxemia during OSA has been implicated in cognitive impairment. OSA during rapid eye movement (REM) sleep is usually more severe than in non-rapid eye movement (NREM) sleep, but the relative effect of oxyhemoglobin desaturation during REM versus NREM sleep on memory is not completely characterized.

Objective: The intricate neuroanatomical structure of the cerebellum is of longstanding interest in epilepsy, but has been poorly characterized within the current corticocentric models of this disease. We quantified cross-sectional regional cerebellar lobule volumes using structural magnetic resonance imaging in 1602 adults with epilepsy and 1022 healthy controls across 22 sites from the global ENIGMA-Epilepsy working group.
Methods: A state-of-the-art deep learning-based approach was employed that parcellates the cerebellum into 28 neuroanatomical subregions.
