Exercise has protective effect on brains of multiple sclerosis patients | Exercise is good for the brains of patients with multiple sclerosis, a new study has found. In
the new study, researchers found that highly fit multiple sclerosis patients performed
significantly better on tests of cognitive function than similar less-fit patients.
In addition, MRI scans of the patients showed that the fitter MS patients showed
less damage in parts of the brain that show deterioration as a result of MS, as
well as a greater volume of vital gray matter. "We found that aerobic fitness
has a protective effect on parts of the brain that are most affected by multiple
sclerosis," said Ruchika Shaurya Prakash, lead author of the study and assistant
professor of psychology at Ohio State University. "As a result, these fitter patients
actually show better performance on tasks that measure processing speed." The
study, done with colleagues Robert Motl and Arthur Kramer of the University of
Illinois and Erin Snook of the University of Massachusetts, Amherst, appears online
in the journal Brain Research and will be published in a future print edition.
The study involved 21 women diagnosed with relapsing-remitting MS. They were compared
with 15 age- and education-matched healthy female controls. The study assessed
fitness, cognitive function, and structural changes in all participants. |
