SAN FRANCISCO, Nov. 20 (UPI) -- Brain exercise enhances memory and other cognitive abilities of adults over the age of 65, a preliminary U.S. study found.
Dr. Elizabeth Zelinski of the University of Southern California Andrus Gerontology Center, in Los Angeles, released initial data from the Improvement in Memory with Plasticity-based Adaptive Cognitive Training study, a randomized, controlled, double blind trial of 524 healthy elderly adults with half the participants completing up to 40 hours of the computer-based Posit Science Brain Fitness Program.
The Posit Science Brain Fitness Program exercises are based on neuroplasticity -- the brain's ability to "rewire" through intensive, repetitive and progressively challenging activity.
"The changes we saw in the experimental group were significantly larger than the gains in the control group," Zelinski said in a statement. "From a researchers point of view, this was remarkable -- people got better at the tasks trained, those improvements generalized to various standardized measures of memory and people perceived improvements in their lives."
The findings were presented the annual meeting of the Gerontological Society of America, in San Francisco.
