Resting tremor in alcoholic brain disease.

S Bajada, A Fisher

    Clinical and Experimental Neurology
    |January 1, 1977
    PubMed
    Summary

    Wernicke-Korsakoff syndrome can cause a unique resting tremor, a movement disorder. Electrographic analysis revealed complex tremor waves, differing from typical rubral tremor presentations.

    Area of Science:

    • Neurology
    • Movement Disorders
    • Neuroscience

    Background:

    • Alcoholic brain disease, specifically Wernicke-Korsakoff syndrome, is often associated with neurological deficits.
    • Movement disorders are a known complication, but specific tremor types can be atypical.

    Purpose of the Study:

    • To describe an unusual resting tremor observed in two patients with Wernicke-Korsakoff syndrome.
    • To characterize the electrographic properties of this tremor.
    • To compare it with known tremor types, such as rubral tremor.

    Main Methods:

    • Clinical assessment of two patients with Wernicke-Korsakoff syndrome.
    • Electrographic recording of resting tremor.
    • Analysis of tremor wave components and stability.
    • Correlation with neuroimaging findings (MRI).

    Main Results:

    • Both patients presented with a resting tremor as a primary movement disorder.
    • Electrographic recordings demonstrated a stable basic tremor rate with multiple superimposed elements.
    • The tremor shared qualitative similarities with rubral tremor.
    • A mesencephalic lesion was identified in only one of the two patients.

    Conclusions:

    • Wernicke-Korsakoff syndrome can manifest with a distinct resting tremor characterized by complex electrographic features.
    • This tremor may mimic rubral tremor, but its underlying pathophysiology may not always involve a clear mesencephalic lesion.
    • Further research is needed to fully understand the neuroanatomical correlates of this specific movement disorder.
