The conus demyelination syndrome in multiple sclerosis.

M C Taylor, W E Bradley, N Bhatia

    Acta Neurologica Scandinavica
    |February 1, 1984
    PubMed
    Summary

    Multiple sclerosis can cause bowel, bladder, and sexual dysfunction. A specific patient group shows signs of conus medullaris involvement, suggesting a novel neurovisceral dysfunction mechanism in multiple sclerosis.

    Area of Science:

    • Neuroscience
    • Urology
    • Gastroenterology

    Background:

    • Bowel, bladder, and sexual dysfunction are common symptoms in multiple sclerosis (MS).
    • These dysfunctions are typically attributed to widespread demyelination affecting the central nervous system.
    • Current understanding often overlooks specific neurological mechanisms contributing to these MS-related issues.

    Observation:

    • A distinct subset of multiple sclerosis patients presented with specific urinary symptoms: hesitancy, straining, and incomplete voiding.
    • Clinical examination revealed perineal hypesthesia.
    • Diagnostic tests, including cystometry, colonometry, and electrophysiology, indicated involvement of the conus medullaris.

    Findings:

    • The observed clinical presentation and diagnostic findings suggest a specific pattern of neurovisceral dysfunction in multiple sclerosis.

    Related Experiment Videos

  • Electrophysiological parameters pointed towards the conus medullaris as a key area of involvement.
  • This points to a previously undocumented mechanism for neurovisceral dysfunction in MS.

    • Implications:

    • This study highlights a specific, potentially localized, neurological cause for bowel and bladder dysfunction in a subset of MS patients.
    • Understanding conus medullaris involvement may lead to more targeted diagnostic and therapeutic strategies for neurovisceral dysfunction in multiple sclerosis.
    • Further research is warranted to validate this mechanism and explore its broader implications in MS patient care.
