First author Larry Baer explains that, "retirement usually occurs right around the time when normal age-related declines in cognitive function come to the fore. So it is important to understand what is happening to brainpower during this period and to identify risk factors for mental decline, as well as factors that will help protect against it."
This study has far-reaching implications. Says Baer, "it is my hope that these results will influence the design of future interventions aimed at maintaining the cognitive health of retirees. This can be done by focusing on getting people to intensify their engagement in a variety of cognitive activities even if they have lower levels of motivation to do so. It is equally important to address symptoms of depression to help fight against cognitive decline."
Baer, who is currently a PhD candidate at Concordia, worked with fellow researchers Nassim Tabri, Mervin Blair and Dorothea Bye, under the leadership of senior authors Dolores Pushkar and Karen Li. They used data collected over four years, from 333 recent retirees. Participants, who were an average age of 59 and mostly in good health and free of any serious mobility limitations when the study started, underwent assessments of cognition, motivation and activities once a year.
