Description

Through our ongoing research, we seek to identify early indicators of cognitive change in individuals sixty years of age and older. We are particularly interested in the relationship between depression questionnaires and learning, attention, memory, spatial problem solving, and executive functioning assessed by the Cogstate computerized cognitive battery. The Geriatric Depression Scale, Beck's Depression Inventory, and the Center of Epidemiological Studies Depression Scale questionnaires are administered every six months to gauge depressive symptoms. During the same six-month visit, participants complete various Cogstate assessments encompassing identification, detection, and memory playing card related tasks, numerous Groton Maze learning tasks and a recall task, and memorization and a delayed recall of the International Shopping List Test.

Through our preliminary data analysis, we have identified significant correlations between each depression score and all the Groton Maze tests, especially during the first trial. Significant relationships, and trends toward significance, were recognized for all four trials of the International Shopping List Tests and the three depression measures, as well as the speed of completion of One Card Back and the Geriatric Depression Scale. Data collection is ongoing and will be re-analyzed to confirm whether these findings extend to the final study sample.
