Central somatosensory conduction time (CSCT) increases with age, particularly after 40. Asymmetry in CSCT shows a slight increase after age 60.

Area of Science:

  • Neuroscience
  • Gerontology
  • Physiology

Background:

  • Central somatosensory conduction time (CSCT) is a measure of neural pathway integrity.
  • Understanding age-related changes in CSCT is crucial for neurological health assessment.

Purpose of the Study:

  • To investigate the effects of aging on CSCT in healthy individuals.
  • To establish normative values for CSCT and its asymmetry across different age groups.

Main Methods:

  • 125 neurologically healthy subjects aged 10-79 years were studied.
  • CSCT and its asymmetry (right-left difference) were measured.
  • Subjects were categorized into six age groups.

Main Results:

  • A mean overall increase of 0.5 ms in CSCT was observed across the studied age range.

  • The primary increase in CSCT began after the fourth decade, showing a steady rise thereafter.
  • Age-dependent changes in asymmetry remained stable until the sixth decade, with a minor increase after age 60.

    • Conclusions:

    • CSCT demonstrates a gradual age-related increase, becoming more pronounced after age 40.
    • Normative limits for CSCT and asymmetry were defined for different age strata, aiding in clinical interpretation.
