Exercise and Aging Brain

Did you know that results from MRI studies at the University of North Carolina in Chapel Hill have correlated physical exercise with blood flow and vessel diameter in the brain? Exercise was found to be associated with an increase in the number of large-diameter vessels in the cerebral region of the brain and with an increase in blood flow in the three major cerebral arteries—in older individuals. The cerebral region is believed to control functions that include consciousness, memory, initiation of activity, emotional response, language,and word associations. Narrowing of and/or loss of small vessels may contribute to cognitive decline. (http://uk.reuters.com/article/healthNews/idUKTRE4B16SZ20081202?sp=true)
