Effects of an interactive computer-based cognitive fitness system on memory, cognition, and overall well-being in older adults

Objective: Age-related memory impairment can have a significant impact on the quality of life of older adults. Previous studies of specific memory techniques as well as a brain plasticity-based training program have shown improved objective memory performance scores among healthy older adults (Ball, et al., 2002; Ivgi, Beeri, Rabinowitz, & Davidson, 1999; Mahncke, et al., 2006), as well as a decreased likelihood of functional decline in self-reported instrumental activities of daily living (Willis, et al., 2006). Yet, objective outcome data on the efficacy of such mentally stimulating programs are minimal. The purpose of this study is to determine if an eight-week program using a computer-based cognitive fitness system will result in improved memory, cognition, and overall well-being in older adults.

Participants and Methods: In order to obtain a representative sample of older adults, thirty participants (mean age 73), without a clinical diagnosis of dementia, were recruited from an affordable-housing retirement community. The intervention consisted of 30-minute sessions, 5 days per week over an 8-week period, with testing at baseline and post-intervention. The control group watched educational videos for a comparable time.

Results: A comparison of follow-up to baseline scores for subjective and objective memory performances, mood, physical functioning, and quality of life measures will be obtained for the control and intervention groups. The results will be available at the conclusion of the study in March 2008.

Implications: This study will contribute to the existing data regarding the relationship between participation in cognitively stimulating programs and cognitive functioning among older adults.
