Examining cognitive differences in expert meditators and non-meditators older adults.

Scientific Reports May 15, 2025 Florence Requier, Hamed Mohammadi, Harriet Demnitz-King et al.

With aging, slight changes in some cognitive processes can be observed. Therefore, we aimed to assess if meditation expertise is associated with preserved cognition in key domains affected in aging. We used data from two older-adult samples of the Medit-Ageing Age-well Study: 135 non-meditators and 27 expert meditators. We examined group differences in four objective cognitive domains...
