Research Reveals Positive Roles for Exercise, Diet, and Meditation in Aging and Depression—Neuroscience 2013
New studies released on Sunday, November 10, 2013, underscore the potential impact of healthy lifestyle choices in treating depression, the effects of aging, and learning. The research focused on the effects of mind/body awareness, exercise, and diet, and was presented in San Diego at Neuroscience 2013, the annual meeting of the Society for Neuroscience and the world’s largest source of emerging news about brain science and health. The 2013 meeting is being attended by approximately 30,000 scientists. The experiences and choices people make throughout life actively impact the brain. As humans live longer, these choices also affect aging and quality of life. Lifestyle changes to diet and exercise will be important to aging populations as non-drug, easy-to-follow interventions with few side effects, making ideal potential therapies. Today’s new findings show that: as few as 12 consecutive days of exercise in aging rats helps preserve and improve movement function, an effect possibly caused by changes in dopamine levels. The results suggest that exercise could stave off or reverse the slowed movements that are hallmarks of age (Jennifer Arnold, abstract 334.02); practices like yoga or meditation that increase mind/body awareness help people learn a brain-computer interface quicker. This finding may have implications for those who need brain-computer interfaces to function, such as people with paralysis (Bin He, Ph.D., abstract 16.06); long-term exercise in aging rats improves memory function, as well as increases the number of blood vessels in the white matter of their brains — the tracts that carry information between different areas of the brain.
