Poor Fitness Linked to Weaker Brain Fiber and Higher Risk of Dementia. Summary: UT Southwestern researchers shed light on the link between poor fitness and an increased risk of developing dementia. Researchers report a lower level of fitness is associated with faster deterioration of white matter fibers in the brain. The deterioration can result in cognitive decline and memory problems as a person ages. Scientists have more evidence that exercise improves brain health and could be a lifesaving ingredient that prevents Alzheimer’s disease. In particular, a new study from UT Southwestern’s O’Donnell Brain Institute suggests that the lower the fitness level, the faster the deterioration of vital nerve fibers in the brain. This deterioration results in cognitive decline, including memory issues characteristic of dementia patients. #gym #gymgirl #gymmotivation #gymrat #gymmemes #gymtime #gymaddict #gymlifestyle #gymjunkie #gymlife #gymnastics #gymshark #gymflow #gymsharkwomen #gymshark66 #gymlove #gymgirls #gymflo #gymnasticsmom #gymnasticsfails #gymfreak #gymselfie #gymvirtual #gymworkouts #gymsharkleggings #gymlover #gymnasticsshoutouts #gymmom #gymjunky #gymworkout https://www.instagram.com/p/COP_DpoBDOj/?igshid=1ozkcijljy3wb
