Choline chloride effects on memory in the elderly

R C Mohs, K L Davis, J R Tinklenberg

    Neurobiology of Aging
    |January 1, 1980
    PubMed
    Summary

    Choline chloride supplementation did not improve memory performance in elderly individuals. Studies indicate this supplement is ineffective for enhancing memory in non-demented older adults.

    Area of Science:

    • Neuroscience
    • Gerontology
    • Pharmacology

    Background:

    • Cognitive decline is a concern in aging populations.
    • Choline is a nutrient vital for brain function, including memory.
    • Previous research on choline's memory-enhancing effects in the elderly is inconclusive.

    Purpose of the Study:

    • To evaluate the efficacy of choline chloride in improving memory function in non-demented elderly individuals.
    • To assess choline chloride's impact on memory storage, retrieval, and working memory capacity.

    Main Methods:

    • A placebo-controlled, crossover study design was employed.
    • Ten subjects over age 60 received choline chloride (2 g QID) or placebo over several weeks.
    • Memory performance was assessed using standardized tests at multiple time points.

    Main Results:

    • Choline chloride administration showed no significant improvement in memory storage or retrieval.
    • Performance on the digit span test, a measure of working memory, was not significantly affected.
    • Correlational analysis revealed no link between baseline memory and choline's effect on performance.

    Conclusions:

    • Choline chloride is not an effective agent for improving memory in non-demented elderly patients.
    • Findings align with previous studies suggesting limited cognitive benefits of choline in this demographic.
    • Further research may explore other interventions for cognitive enhancement in aging individuals.
