    Rheoencephalography (REG) revealed reduced brain blood vessel elasticity in older adults. This study assessed cerebral circulation across two age groups, highlighting age-related changes.

    Area of Science:

    • Neuroscience
    • Medical Physiology
    • Gerontology

    Background:

    • Cerebral circulation is vital for brain health.
    • Age-related changes in vascular elasticity can impact brain function.
    • Assessing brain blood flow non-invasively is crucial.

    Purpose of the Study:

    • To evaluate brain circulation using rheoencephalography (REG) in healthy adults.
    • To compare cerebral hemodynamic parameters between younger and older age groups.
    • To investigate the effect of aging on cerebral blood vessel elasticity.

    Main Methods:

    • Rheoencephalography (REG) was employed to assess brain circulation.
    • Forty healthy subjects were divided into two groups: 20-45 years and 46-73 years.
    • REG recordings were analyzed visually, calculating indices and means from ten waves per side.

    Main Results:

    • A significant difference in cerebral blood vessel elasticity was observed between the age groups.
    • Older adults (46-73 years) exhibited reduced blood vessel elasticity compared to younger adults (20-45 years).
    • REG parameters indicated age-related alterations in cerebral hemodynamics.

    Conclusions:

    • Reduced elasticity of cerebral blood vessels is a characteristic of aging.
    • Rheoencephalography is a viable method for assessing age-related changes in brain circulation.
    • Findings suggest potential implications for cerebrovascular health in older populations.
