Meditation for Brain Health

Building on their earlier work that suggested people who meditate have less age-related atrophy in the brain’s white matter, a new study by UCLA researchers found that meditation appeared to help preserve the brain’s gray matter, the tissue that contains neurons.
Scientists looked specifically at the association between age and gray matter. They compared 50 people who had mediated for years and 50 who didn’t. People in both groups showed a loss of gray matter as they aged. But the researchers found among those who meditated, the volume of gray matter did not decline as much as it did among those who didn’t. Those who meditated had been doing so for four to 46 years, with an average of 20 years.
Dr. Florian Kurth, a co-author of the study and postdoctoral fellow at the UCLA Brain Mapping Center, said the researchers were surprised by the magnitude of the difference.
“We expected rather small and distinct effects located in some of the regions that had previously been associated with meditating,” he said. “Instead, what we actually observed was a widespread effect of meditation that encompassed regions throughout the entire brain.”
