Medical Research: What is the background for this study? What are the main findings?
Dr. Sandry: We were interested in better understanding the relationship between cognitive reserve and long-term memory impairment in moderate to severe Traumatic Brain Injury, from a cognitive perspective. The theory of cognitive reserve suggests that individuals who engage in intellectually enriching activities may be less susceptible to the negative cognitive consequences of long-term memory impairment that often accompanies neurological disorders. There’s significant evidence in support of cognitive reserve; however, it’s somewhat unclear what particular cognitive processes are involved in this relationship and how those cognitive processes may differ across high and low reserve individuals. We derived our predictions on the basis of well-established cognitive theory and found that working memory capacity partially mediates the cognitive reserve – long-term memory relationship in Traumatic Brain Injury. Or to put it another way, working memory may be one underlying cognitive process involved in this relationship. Importantly, this finding corroborates some recent related work we have conducted in multiple sclerosis.
