iMeditate for Older Adults with Mild Cognitive Impairment

Individuals diagnosed with mild cognitive impairment (MCI) are at a high risk of developing dementia and are an important target population for interventions that may reduce the risk of cognitive decline. A diagnosis of MCI or dementia also has an important impact on caregivers, who show increased levels of stress, anxiety, and depression. Mindfulness meditation is a promising behavioural intervention that may have important benefits both for older adults with MCI and for caregivers. Previous research suggests that meditation may improve psychological wellbeing, reduce stress, and even improve cognitive function. Technology-based mindfulness meditation platforms may be a much-needed solution for promoting the adoption of mindfulness in these populations. The current study is a pilot randomized control trial of a mindfulness meditation intervention delivered via the Muse platform in two study populations: a) older adults diagnosed with MCI, and b) family caregivers of persons with MCI or neurodegenerative disorders. Muse is a mobile application for meditation that provides real-time feedback about the user's state of mindfulness during meditation via a headband containing electroencephalographic sensors (EEG) that the user wears while meditating. It is thought that this neurofeedback can promote learning and lead to faster improvements in meditation ability and, consequently, greater benefits from meditation practice. This aim of this pilot study is to establish the acceptability of the Muse platform as an intervention in the two study populations, to determine the feasibility of the randomized control trial designed to evaluate the effectiveness of a 6 week intervention with the Muse platform, and to evaluate the effect of neurofeedback on meditation. Participants will be randomly allocated to meditation with neurofeedback (NFB) or meditation without neurofeedback (no-NFB) and will complete daily meditation sessions for 6 weeks. An assessment visit before and after the intervention will evaluate participants' psychological well-being using questionnaires; their visual working memory, attention, and visual perception using behavioural tests; and their mindfulness ability using questionnaires and a behavioural measure. EEG will also be recorded using the Muse headband to examine changes in electrophysiological markers during cognitive tests and at rest.
