A double-blind randomized controlled trial with 75 patients with mild cognitive impairment and insomnia found that mindfulness therapy significantly improved sleep quality, cognitive function, and reduced anxiety and perceived stress compared to health education. The mindfulness group showed significant improvements in sleep and cognition, with confidence intervals indicating reliable effects. EEG data revealed significant differences in delta, theta, beta, and gamma brainwave bands between rest and mindfulness states, suggesting deep relaxation and changes in attention-related brain activity. No deaths or serious adverse events occurred. Mindfulness can be successfully learned by individuals with mild cognitive impairment and is suitable for use in nursing homes.
