Neuromyelitis optica (Devic's syndrome) in two sisters

L T Ch'ien, M O Medeiros, J J Belluomini

    Clinical EEG (Electroencephalography)
    |January 1, 1982
    PubMed
    Summary

    Neuromyelitis optica (Devic's syndrome) rarely affects siblings. This study details two sisters with Devic's syndrome, suggesting a potential genetic link for this rare neurological disorder.

    Area of Science:

    • Neurology
    • Genetics
    • Ophthalmology

    Background:

    • Neuromyelitis optica (Devic's syndrome) is typically a sporadic autoimmune disease affecting the optic nerves and spinal cord.
    • Understanding the genetic factors in rare neurological disorders is crucial for diagnosis and treatment.

    Observation:

    • Two sisters, aged 6 and 10, presented with simultaneous onset of Devic's syndrome at age 3.
    • Clinical presentation included severe vision loss, paraparesis, scoliosis, and spinal cord dysfunction.

    Findings:

    • Electrodiagnostic tests objectively quantified neurological deficits, correlating with clinical severity.
    • Both optic nerves and spinal cord showed significant tissue damage in both patients.

    Implications:

    • The familial occurrence of Devic's syndrome in this case raises the possibility of shared genetic susceptibility.
    • Further research into genetic factors may elucidate the pathogenesis of neuromyelitis optica.
