Engaging in regular physical activity is associated with less decline in cognitive function in older adults, according to two studies published Online First by Archives of Internal Medicine, one of the JAMA/Archives journals.

The researchers analyzed data to correlate cognitive score changes with total physical activity and energy expenditure from walking. As participants' energy expenditure increased, the rate of cognitive decline decreased. The amount of exercise equivalent to a brisk, 30-minute walk every day was associated with lower risk of cognitive impairment.

If confirmed in future studies, physical activity recommendations could yield substantial public health benefits given the growing number of older persons with vascular conditions and their high risk of cognitive impairment.
