Centrophenoxine: effects on aging mammalian brain.

K Nandy

    Journal of the American Geriatrics Society
    |February 1, 1978
    PubMed
    Summary

    Centrophenoxine improved learning and memory in aged mice, correlating with reduced neuronal lipofuscin accumulation in the brain. This suggests potential benefits for age-related cognitive decline.

    Area of Science:

    • Neuroscience
    • Gerontology
    • Pharmacology

    Background:

    • Aging is associated with cognitive decline and increased lipofuscin in neurons.
    • Lipofuscin, an age pigment, accumulates in the brain with age.
    • Centrophenoxine is a potential therapeutic agent for age-related changes.

    Purpose of the Study:

    • To investigate the effects of centrophenoxine on learning and memory in aged mice.
    • To correlate cognitive changes with alterations in neuronal lipofuscin.
    • To assess the impact of centrophenoxine on brain aging markers.

    Main Methods:

    • Aged female mice were treated with centrophenoxine for three months.
    • Learning and memory were evaluated using a T-maze task.
    • Neuronal lipofuscin levels were assessed via autofluorescence, histochemistry, and electron microscopy.

    Main Results:

    • Centrophenoxine-treated mice demonstrated significantly improved learning compared to untreated aged mice.
    • A reduction in neuronal lipofuscin was observed in the cerebral cortex and hippocampus of treated mice.
    • Cognitive improvements correlated with decreased lipofuscin accumulation.

    Conclusions:

    • Centrophenoxine enhances cognitive function in aged mice.
    • The drug reduces neuronal lipofuscin, a marker of cellular aging.
    • Centrophenoxine shows promise in mitigating age-related cognitive impairment and brain aging.
