Poor sleep is common among adults aged 55 and older who live with mild cognitive impairment (MCI), and it tends to travel with faster cognitive decline and a lower quality of life. Sleep medication is still widely used in this group despite safety concerns, which is why researchers keep looking for gentler options.
What was reviewed A systematic review and meta-analysis in Geriatric Nursing pooled the available evidence on meditation-based interventions for sleep in adults aged 55 and older with MCI. It is a small field: seven studies met the inclusion criteria, with 434 participants in total across all seven. The studies were not all randomized trials. The authors also accepted pilot randomized trials and quasi-experimental studies, and the programs themselves varied (mindfulness, mantra, sound meditation and hybrid formats), lasting 4 to 12 weeks.
What it found Five of the seven studies reported significantly better subjective sleep quality, meaning sleep as the participants themselves rated it. Six studies used the Pittsburgh Sleep Quality Index (PSQI), a questionnaire where a lower score means better sleep. Pooled together, they showed an improvement (Hedges' g = -0.75, 95% CI -1.23 to -0.28). The minus sign is the good news here: scores went down, so sleep quality went up. One study that tracked sleep with a wrist sensor (actigraphy) found less daytime napping. Secondary outcomes included less anxiety, stress and depression, and better attention and memory.
Why the number needs care The studies disagreed with each other more than chance would explain. The review reports substantial heterogeneity (I² = 77.9%), so the pooled -0.75 is an average of quite different results, and the wide confidence interval (-1.23 to -0.28) says the true effect could be modest or large. Add the small total sample, the short follow-up, the mix of meditation styles, and the fact that nearly everything rests on self-reported sleep, with only one study using an objective measure. The authors still rate the certainty of the evidence as moderate, but they say plainly that caution is warranted.
What would settle it Larger multi-site randomized trials with standardized programs, measuring sleep both by questionnaire and by objective devices.
The bottom line For adults aged 55 and older with MCI, meditation-based programs look like a reasonable supportive option for improving self-reported sleep, and an alternative worth exploring alongside, not instead of, medical advice. The evidence is still limited and inconsistent, so treat it as promising rather than proven.
