Yoga practitioners were also found to fare better on mental performance tests, the study team observed.
Dr. Thomas Vidic, a neurologist at Elkhart General Hospital in Elkhart, Ind., who was not involved in the study, said he was not surprised by the findings.
“There have been numerous studies that show that mental and physical activity is useful [and] probably necessary — to maintaining brain function,” said Vidic, who is also a member of the American Academy of Neurology.
