Key Points

The central aim is to identify how structural connectivity relates to cognitive performance, sleep patterns, and sex differences in older adults.
Analysed data from the Brain Resilience Study
Examined structural connectivity networks in participants
Assessed cognitive performance and sleep quality across sexes
Identified significant correlations between structural connectivity and cognitive performance
Noted sex differences in cognitive and sleep assessments
Found variations in resilience factors linked to network features

Abstract

Poster created for Cognitive Neuroscience Society (CNS) 2026 Annual Meeting. The Brain Resilience Study (https://brainresilience.ca/) aims to identify factors that modulate individual differences in aging by examining resilience factors, alongside cognitive and neurobiological variables. In this study, we examined sex differences in how sleep and cognition relate to structural network features in older adults.
