Effects of an 18-month meditation training on subjective and objective sleep quality in older adults: a secondary analysis of the Age-Well randomized controlled trial

medRxiv October 2, 2026 Pierre Champetier, Anaïs Hamel, Stéphane Rehel et al. preprint

Abstract Study objectives Aging is associated with increased sleep complaints and changes in sleep architecture, microstructure and rest-activity rhythms. Meditation-based interventions have shown benefits on subjective sleep quality, but their effects on objective sleep parameters remain largely underexplored. This study investigated the effects of an 18-month meditation intervention on sleep...

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...

The evolution of subjective cognition after meditation training in older people: a secondary analysis of the three-arm age-well randomized controlled trial.

Neuropsychology, development, and cognition. Section B, Aging, neuropsychology and cognition March 1, 2025 Florence Requier, Harriet Demnitz-King, Eric Frison et al.

Aging is associated with cognitive changes, even in the absence of brain pathology. This study aimed to determine if meditation training, by comparison to active and passive control groups, is linked to changes in the perception of cognitive functioning in older adults. One hundred thirty-four healthy older participants from the Age-Well Randomized Clinical Trial were included: 45 followed a...

Decoding meditation mechanisms underlying brain preservation and psycho-affective health in older expert meditators and older meditation-naive participants.

Scientific Reports November 27, 2024 Sacha Haudry, Anne-Laure Turpin, Brigitte Landeau et al. 3 citations

Meditation is a mental training approach that can improve mental health and well-being in aging. Yet the underlying mechanisms remain unknown. The Medit-Ageing model stipulates that three mechanisms - attentional, constructive, and deconstructive - upregulate positive psycho-affective factors and downregulate negative ones. To test this hypothesis, we measured brain structural MRI and...

Meditation dosage predicts self- and teacher-perceived responsiveness to an 18-month randomised controlled trial

Scientific Reports November 2, 2024 Marco Schlosser, Julie Gonneaud, Stefano Poletti et al. 2 citations

Understanding the factors that predict why some individuals perceive to respond more to meditation training than others could impact the development, efficacy, adherence levels, and implementation of meditation-based interventions. We investigated individual-level variables associated with self- and teacher-perceived responsiveness to longer-term meditation training. This study presents a...

Effects of Meditation Training and Non-Native Language Training on Cognition in Older Adults: A Secondary Analysis of a Randomized Clinical Trial.

JAMA Network Open July 3, 2023 Harriet Demnitz-King, Florence Requier, Tim Whitfield et al.

Nonpharmacological interventions are a potential strategy to maintain or promote cognitive functioning in older adults. To investigate the effects of 18 months' meditation training and 18 months' non-native language training on cognition in older adults. This study was a secondary analysis of the Age-Well trial, an 18-month, observer-masked, randomized clinical trial with 3 parallel arms....

Effect of an 18-Month Meditation Training on Regional Brain Volume and Perfusion in Older Adults

JAMA Neurology October 10, 2022 Gaël Chételat, Antoine Lutz, Olga Klimecki et al. 45 citations

Importance: No lifestyle-based randomized clinical trial directly targets psychoaffective risk factors of dementia. Meditation practices recently emerged as a promising mental training exercise to foster brain health and reduce dementia risk. Objective: To investigate the effects of meditation training on brain integrity in older adults. Design, Setting, and Participants: Age-Well was a...

Effects of a mindfulness-based versus a health self-management intervention on objective cognitive performance in older adults with subjective cognitive decline (SCD): a secondary analysis of the SCD-Well randomized controlled trial.

Alzheimer's Research & Therapy September 6, 2022 Tim Whitfield, Harriet Demnitz-King, Marco Schlosser et al.

Older individuals with subjective cognitive decline (SCD) perceive that their cognition has declined but do not show objective impairment on neuropsychological tests. Individuals with SCD are at elevated risk of objective cognitive decline and incident dementia. Non-pharmacological interventions (including mindfulness-based and health self-management approaches) are a potential strategy to...
