Aerobic Exercise Assists Cognitive Health

Previous brain imaging studies have consistently revealed objective evidence of favorable effects of exercise on human brain integrity. As well, animal research has shown that exercise generates trophic factors that improve brain functioning, and exercise facilitates brain connections (neuroplasticity). Eric Ahlskog, from Mayo Clinic (Minnesota, USA), and colleagues report that exercise sufficient to raise the heart rate and increase the body's need for oxygen may help to reduce the risk of dementia and slow the condition's progression once it starts.   The team reviewed 1,600 papers, including 130 that specifically explored the relationship between exercise and cognitive function. Writing that: “Besides a brain neuroprotective effect, physical exercise may also attenuate cognitive decline via mitigation of cerebrovascular risk, including the contribution of small vessel disease to dementia,” The researchers conclude that: “Exercise should not be overlooked as an important therapeutic strategy.”
