Objective. To investigate the effects of an 8-week meditation program on perceived stress, sleep, mood, and related outcomes in adults with cognitive impairment and their caregivers.Methods. Community-dwelling adults with a diagnosis of mild cognitive impairment or early-stage Alzheimer’s disease, together with their live-in caregivers, were enrolled in the study. After a brief training, participants were asked to meditate for 11 minutes, twice daily for 8 weeks. Major outcomes included measures of perceived stress (Perceived Stress Scale), sleep (General Sleep Disturbance Scale), mood (Profile of Mood States), memory functioning (Memory Functioning Questionnaire), and blood pressure. Participants were assessed pre- and post-intervention.Results. Ten participants (5 of 6 dyads) completed the study. Treatment effects did not vary by participant status; analyses were thus pooled across participants. Adherence was good (meditation sessions completed/week:X=11.4±1.1). Participants demonstrated improvement in all major outcomes, including perceived stress (P<0.001), mood (overall,P=0.07; depression,P=0.01), sleep (P<0.04), retrospective memory function (P=0.04), and blood pressure (systolic,P=0.004; diastolic,P=0.065).Conclusions. Findings of this exploratory trial suggest that an 8-week meditation program may offer an acceptable and effective intervention for reducing perceived stress and improving certain domains of sleep, mood, and memory in adults with cognitive impairment and their caregivers.
