Exercise Can Aid Recovery After Brain Radiation

“Exercise is a key factor in improving both memory and mood after whole-brain radiation treatments in rodents, according to data presented by Duke University scientists at the Society for Neuroscience meeting. "This is the first demonstration that exercise can prevent a decline in memory after whole-brain radiation treatment," said lead researcher and graduate student Sarah Wong-Goodrich of the Duke Department of Psychology and Neuroscience. Whole-brain radiation is sometimes used to treat brain cancers in humans. ’We found that exercise following radiation prevented a decline in erasable memory in mice and this is analogous to the type of memory problems people have after whole-brain radiation for brain tumors,’ said senior researcher Christina Williams, Ph.D., professor of psychology and neuroscience. ‘This is the type of short-term memory people use to find their car after they have parked it in a large lot. After radiation, this type of memory becomes impaired in many people.’”
