Central nervous system involvement in progressive muscular dystrophy

M Yoshioka, T Okuno, Y Honda

    Archives of Disease in Childhood
    |August 1, 1980
    PubMed
    Summary

    Progressive muscular dystrophy affects the central nervous system, revealing abnormalities via CT scans and EEGs. Findings include white matter changes in congenital forms and cerebral atrophy in Duchenne dystrophy.

    Area of Science:

    • Neurology
    • Medical Imaging
    • Genetics

    Background:

    • Progressive muscular dystrophy (PMD) is a group of inherited disorders characterized by muscle weakness.
    • Previous research has primarily focused on the myogenic aspects of PMD.
    • The involvement of the central nervous system (CNS) in PMD requires further investigation.

    Purpose of the Study:

    • To investigate central nervous system (CNS) abnormalities in patients with progressive muscular dystrophy.
    • To correlate neuroimaging and electrophysiological findings with specific types of muscular dystrophy.

    Main Methods:

    • Utilized computerised tomography (CT) scans for neuroimaging.
    • Performed electroencephalograms (EEGs) to assess brain electrical activity.
    • Employed psychometric and ophthalmological examinations for comprehensive patient evaluation.

    Main Results:

    • Congenital muscular dystrophy showed characteristic low-density white matter areas on CT scans (56% of cases).
    • Duchenne dystrophy exhibited slight cerebral atrophy (67% of cases), worsening with age.
    • EEG abnormalities (spike or spike-and-wave complexes) and optic atrophy were noted in congenital cases.

    Conclusions:

    • Progressive muscular dystrophy is not solely a myogenic disorder but significantly impacts the central nervous system.
    • CT scan findings, particularly white matter changes and cerebral atrophy, are indicative of CNS involvement in PMD.
    • Further research into the neurological manifestations of PMD is warranted.
