This research, conducted by investigators at UCLA Medical Center and the University of Pittsburgh, is the first to show that virtually any type of aerobic physical activity can improve brain structure and reduce Alzheimer's risk.

The results of the analysis showed that increasing physical activity was correlated with larger brain volumes in the frontal, temporal, and parietal lobes including the hippocampus. Individuals experiencing this brain benefit from increasing their physical activity experienced a 50% reduction in their risk of Alzheimer's dementia. Of the roughly 25% in the sample who had mild cognitive impairment associated with Alzheimer's, increasing physical activity also benefitted their brain volumes.

Said lead author Cyrus A. Raji, MD, PhD, of UCLA, "This is the first study in which we have been able to correlate the predictive benefit of different kinds of physical activity with the reduction of Alzheimer's risk through specific relationships with better brain volume in such a large sample."
