International audience. With aging, slight changes in some cognitive processes can be observed. Therefore, we aimed to assessif meditation expertise is associated with preserved cognition in key domains affected in aging. Weused data from two older-adult samples of the Medit-Ageing Age-well Study: 135 non-meditators and27 expert meditators. We examined group differences in four objective cognitive domains (attention,executive functioning, episodic memory, and global cognition) and three subjective scores: CognitiveDifficulties Scale (CDS) total score as well as Attentional Style Questionnaire (ASQ) internal andexternal scores using generalized mixed effect models, controlling for age, sex, and education. We didnot observe group differences on attentional, executive and global cognitive scores or on ASQ internalscore and CDS total score. However, meditators reported less external distraction (ASQ externalscore) and had better memory than non-meditators. These cross-sectional results indicate a bettermanagement of external stimuli and higher memory performance in expert meditators. Memorydifficulties and distractions being the main complaints of older people, prolonged meditation practicecould lead them to greater cognitive capacities important for healthy aging.
