Computed tomography and aging: results in a normal elderly population.

P A Laffey, R G Peyster, R Nathan

    Neuroradiology
    |January 1, 1984

    Summary

    Brain imaging in elderly individuals reveals age-related ventricular enlargement and cortical atrophy, more pronounced in men. Most normal elderly individuals show minimal or no such changes.

    Area of Science:

    • Neurology
    • Radiology
    • Gerontology

    Background:

    • Age-related changes in the brain are common.
    • Understanding normal aging patterns is crucial for diagnosing neurological conditions.

    Purpose of the Study:

    • To investigate the relationship between age, sex, ventricular enlargement, and cortical atrophy in a cohort of normal elderly individuals.
    • To establish normative data for brain structure changes in aging.

    Main Methods:

    • Computed Tomography (CT) scans of 212 healthy elderly participants were analyzed.
    • Quantitative assessments of ventricular size and cortical atrophy were performed.

    Main Results:

    • A positive correlation was observed between ventricular enlargement and chronological age.

    Related Experiment Videos

  • Men exhibited greater degrees of ventricular enlargement and cortical atrophy compared to women.
  • 86% of participants showed mild, minimal, or no cortical atrophy, suggesting significant brain structure preservation in normal aging.

    • Conclusions:

    • Ventricular enlargement and cortical atrophy are associated with aging in the elderly.
    • Sex influences the extent of these age-related brain changes.
    • Significant brain structure preservation is evident in the majority of normal elderly individuals.
