Memory changes in the Benton Visual Retention Test between ages 70 and 75.

K Shichita, S Hatano, Y Ohashi

    Journal of Gerontology
    |May 1, 1986
    PubMed
    Summary

    Memory in Japanese older adults declined over five years, but higher education and activity levels helped preserve cognitive function. Initial memory performance was the strongest predictor of later memory scores.

    Area of Science:

    • Gerontology
    • Cognitive Psychology
    • Neuroscience

    Background:

    • Cognitive decline is a significant concern in aging populations.
    • Understanding factors influencing memory in older adults is crucial for developing interventions.
    • Previous research suggests education and lifestyle may impact cognitive aging.

    Purpose of the Study:

    • To investigate the longitudinal effects of education and activity on memory in Japanese older adults.
    • To identify predictors of memory performance over a five-year period.

    Main Methods:

    • A cohort of 302 Japanese older adults (aged 69-71) completed the Benton Visual Retention Test.
    • Participants were retested five years later (aged 75).
    • Multiple regression analysis was used to assess the influence of initial memory score, education, activity, and sex on subsequent memory performance.

    Main Results:

    • Memory scores, as measured by the Benton Visual Retention Test, declined in both men and women over the five-year period.
    • The initial memory score was the strongest predictor of the second memory score.
    • Higher levels of education and greater activity engagement were associated with better memory performance after five years.
    • No significant sex differences were observed in the magnitude of memory change.

    Conclusions:

    • Cognitive function, specifically memory, naturally declines with age in older adults.
    • Education and engagement in activities are protective factors that can mitigate memory decline.
    • Longitudinal assessment is vital for understanding age-related cognitive changes and the impact of influencing factors.
