Posted by ashford university on Monday, October 5, 2009 at 8:27pm.

Neurologists involved in animal research studies of cognitive function see analogies in humans that suggest mental exercise reduces loss of brain mass. Which of the following statements describe their findings?

-Older adults who continue complex mental activities can delay or even reverse decline in brain mass that is part of normal aging
-Mental exercise can only slow normal decline in brain mass that is part of normal aging, but no amount of exercise can delay or reverse it
-Mental exercise can help maintain brain mass, but no amount of exercise can slow the decline in cognitive abilities that is part of normal aging
-Older adults who continue complex mental activities can maintain cognitive abilities, but no amount of exercise can affect brain mass

    Note the key words in the question: mental exercise reduces loss of brain mass.

    Only one of the possible answers states that key finding.
