Older Adults Who Meditate Regularly Perform Better on Neuropsychological Functioning and Visual Working Memory Tests: A Three-month Waitlist Control Design Study with a Cohort of Seniors in Assisted Living Facilities.

Background: Neuropsychological functioning and visual working memory are vulnerable to age-related decline. This investigation examines the impact of meditation on the said outcomes for older adults in assisted living facilities. Older adults (N = 136) from four assisted living facilities in Mumbai and Pretoria were randomized into intervention and waitlist control groups.Method: The Repeatable Battery for Assessment of Neuropsychological Status (RBANS) was used as a screening instrument for recruitment (cutoff total index score = 86 ± 4). RBANS, the Simple Object Span Test (SOST), and the Picture Span Test (PST) were used to assess the outcomes. The intervention group underwent a 90-day meditation training complemented with self-practice.Results: Posttest scores of the intervention group were higher. Older adult men, with college degree, middle class, widowed, in fair health, with no diagnosed psychiatric conditions, who attended at least 70 (out of 90) meditation lessons and who self-practiced at least 70 times, gained more from the meditation intervention. Intervention compliance had the strongest effect on posttest outcomes as well as sex and psychiatric morbidities.Conclusion: Meditation intervention needs some refinements for older adult women, with high school education, upper class, currently married, in poor health, with diagnosed anxiety/depression/drug dependence, who attended fewer meditation lessons and self-practiced infrequently.
