    The British Journal of Social and Clinical Psychology

    PubMed
    Summary

    Cognitive assessment in the elderly is refined. Activity enhances performance, while medication can decrease it, modifying previous theories on cognitive tests for normal and depressed individuals.

    Area of Science:

    • Gerontology
    • Cognitive Psychology
    • Psychiatry

    Background:

    • A prior theory (Kendrick, 1972) posited no cognitive test differences between normal and depressed elderly subjects without pseudodementia.
    • Recent research using the Revised Kendrick Battery necessitates theory modification.

    Purpose of the Study:

    • To update the cognitive assessment theory for the elderly.
    • To incorporate the influence of activity and medication on cognitive performance.

    Main Methods:

    • Re-examination of previous studies (Kendrick & Post, 1967; Kendrick, 1972).
    • Analysis of data from the Revised Kendrick Battery.

    Main Results:

    • Cognitive assessment theory requires modification to include activity and medication effects.
    • Activity was found to enhance cognitive performance.
    • Medication was found to decrease cognitive performance.

    Conclusions:

    • The updated theory better explains cognitive assessment in the elderly.
    • Activity and medication are significant factors influencing cognitive test results in the elderly.
