High-impact exercise may improve brain function

A new study finds long-term aerobic activity helps preserve white matter needed for key brain functions.

Scientists say white matter plays a critical role of transmitting messages between different regions of gray matter. That affects seeing, hearing, speaking, memory and our emotions.

Researchers say, without properly functioning white matter, people can begin to show signs of neurological problems.

Scientists reporting from the Texas Health Presbyterian Hospital in Dallas say purposeful, consistent exercise can help fight off dementia and some of the other classic signs of aging.
