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.

Meditation is thought to promote healthy aging by improving mental health, preserving brain integrity and reducing Alzheimer's disease risk. We examined the impact of long-term meditation expertise and an 18-month meditation training on brain aging in older adults using machine learning. We included 25 Older Expert Meditators (OldExpMed) with > 20 years of practice and 135 Cognitively...

EEG Brain Rhythms During Resting-State Wakefulness and Sleep in Elderly Expert Meditators.

Journal of Sleep Research July 29, 2025 Pierre Champetier, Anaïs Hamel, Claire André et al.

Meditation practice has been shown to impact resting-state EEG activity in expert meditators, but its benefits on sleep, which is particularly affected with age, are poorly understood. Our aim was to better understand the effects of long-term meditation practice on resting-state EEG and sleep in older adults. Twenty-seven elderly expert meditators (mean age ± SD: 70.7 ± 5.0 years) were compared...

Effects of an 18-month meditation training on dynamic functional connectivity states in older adults: Secondary analyses from the Age-Well randomized controlled trial

Imaging Neuroscience 2025 Sacha Haudry, Sophie Dautricourt, Julie Gonneaud et al.

Meditation training in older adults has been proposed as a non-pharmacological intervention to promote healthy aging and lower the risks of developing Alzheimer's disease (AD). Resting-state dynamic functional network connectivity (dFNC) highlighted two brain states, the "strongly connected" and "default mode network (DMN)-negatively connected" states, associated with protective factors for...
