    Palatal myoclonus may involve serotonin systems. Clonazepam, a serotonin agonist, provided symptomatic relief for a patient with possible multiple sclerosis, suggesting a therapeutic link.

    Area of Science:

    • Neurology
    • Neurochemistry

    Background:

    • Palatal myoclonus is an involuntary rhythmic contraction of the palate.
    • Multiple sclerosis is a potential underlying condition affecting the central nervous system.

    Observation:

    • A patient presented with palatal myoclonus and possible multiple sclerosis.
    • Cerebrospinal fluid analysis revealed reduced 5-hydroxy-indole-acetic acid, indicating decreased central serotonergic turnover.

    Findings:

    • A therapeutic trial using clonazepam, a serotonergic agonist, resulted in symptomatic improvement of palatal myoclonus.
    • This suggests a potential role for serotonergic pathways in the pathophysiology of palatal myoclonus.

    Implications:

    • The findings suggest that serotonergic inhibitory systems may be involved in the expression of palatal myoclonus.
