Impact of meditation on brain age derived from multimodal neuroimaging in experts and older adults from a randomized trial
Scientific Reports October 28, 2025 Sacha Haudry, Natacha Lambert, Christian Gaser et al.
Older adults with more than 20 years of meditation experience have a younger predicted brain age compared to cognitively unimpaired older adults without such expertise, as measured by a machine learning model trained on brain structure and metabolism data. The difference in brain age was linked to total meditation hours, mental imagery, and prosocialness. However, an 18-month meditation training program did not produce a significant effect on brain age, suggesting that long-term, sustained practice may be necessary to support healthy brain aging.
