UCLA Researchers: To Reduce Pre-Alzheimer’s Cognitive Impairment, Get To The Yoga Mat

Inner peace and a flexible body may not be the most valuable benefits that yoga and meditation have to offer, suggests new research by a UCLA-led team of neuroscientists.

The team found that a three-month course of yoga and meditation practice helped minimize the cognitive and emotional problems that often precede Alzheimer’s disease and other forms of dementia — and that it was even more effective than the memory enhancement exercises that have been considered the gold standard for managing mild cognitive impairment.

“Memory training was comparable to yoga with meditation in terms of improving memory, but yoga provided a broader benefit than memory training because it also helped with mood, anxiety and coping skills,” said Helen Lavretsky, the study’s senior author and researcher at the Semel Institute for Neuroscience and Human Behavior at UCLA.

People with mild cognitive impairment are two-and-a-half times more likely to develop Alzheimer’s disease and other forms of dementia.

The study, which appeared earlier this month in the Journal of Alzheimer’s Disease, is the first to compare outcomes from yoga and meditation with those from memory training, which incorporates activities ranging from crossword puzzles to commercially available computer programs.

The study of 25 participants, all over the age of 55, measured changes not just in behavior but also in brain activity. All participants had reported issues with their memory, such as tendencies to forget names, faces or appointments or to misplace things. They underwent memory tests and brain scans at the beginning and end of the study.

One group received one hour a week of memory enhancement training and spent 20 minutes a day performing memory exercises—verbal and visual association and other practical strategies for improving memory, based on research-backed techniques.

The other group took a one-hour class once a week in Kundalini yoga and practiced Kirtan Kriya meditation at home for 20 minutes each day. Kirtan Kriya, which involves chanting, hand movements and visualization of light, has been practiced for hundreds of years in India as a way to prevent cognitive decline in older adults.

After 12 weeks, the researchers saw similar improvements among participants in both groups in verbal memory skills — which come into play for remembering names and lists of words. But those who had practiced yoga and meditation had better improvements than the other subjects in visual–spatial memory skills, which come into play for recalling locations and navigating while walking or driving.

The yoga–meditation group also had better results in terms of reducing depression and anxiety and improving coping skills and resilience to stress. 

And outward improvements in memory corresponded with perceptible changes in brain activity. But the changes among the yoga group were statistically significant, whereas the changes in the memory group were not.

“A regular practice of yoga and meditation could be a simple, safe and low-cost solution to improving your brain fitness,” Lavretsky said.

The study was funded by the Alzheimer’s Research and Prevention Foundation.
