    Morvan's chorea cases reveal potential triggers like mercury and gold salts. Differentiating fibrillary chorea from Isaacs syndrome involves observing hypotonia and the course of the condition.

    Area of Science:

    • Neurology
    • Immunology

    Background:

    • Morvan's chorea is a rare neurological disorder.
    • Understanding its etiology and distinguishing it from similar conditions is crucial for diagnosis and treatment.

    Observation:

    • Two cases of Morvan's chorea are presented.
    • One patient experienced two episodes, linked to mercury and gold salts.
    • The second patient exhibited facial fibrillations followed by polyradiculoneuritis.

    Findings:

    • The cases suggest a potential immuno-allergic basis for Morvan's chorea.
    • Various agents, including heavy metals (mercury, gold) and infections, may act as triggers.
    • Absence of hypotonia and a regressive course are key features differentiating fibrillary chorea.

    Implications:

    • These findings aid in diagnosing Morvan's chorea and related neuromuscular disorders.
    • Identifying potential triggers can inform preventative strategies.
    • Further research into the immuno-allergic mechanisms is warranted.
