Virtual Exercise (Exergames like Wii Fit or PlayStation Move) May Improve Higher Mental (Brain) Functions Better Than Traditional Exercise in over 50 year old.

Online Health Expert News Report: According to the results of a 2 year study done on 101 volunteers 58 -99 years old, published in the American Journal of Preventive Medicine (January, 2012), Dr. Cay Anderson-Hanley, Assistant Professor at Union College, New York, found that Virtual reality enhanced interactive exercise (Cybercyclists)  yielded greater cognitive benefit and perhaps added greater protection (23% reduction in progression to MCI) against mild cognitive impairment (MCI) compared to traditional exercise.

Exercise could be linked to cognitive function via the increase in the blood levels of Brain-Derived Neurotrophic Growth Factor (BDNF).
