Abstract
Background: Morvan syndrome is characterized by neuromyotonia, dysautonomia, and various neuropsychiatric symptoms, as well as sleep disturbances, although these are less common than neuromuscular symptoms. Herein, we report a case of Morvan syndrome with peculiar sleep disturbances, documented via polysomnography. Case Report: We present herein the case of a 67-year-old man who developed agitation and severe insomnia after undergoing a thymectomy for the treatment of myasthenia gravis, which was subsequently diagnosed as agrypnia excitata due to Morvan syndrome, based on 24-hour polysomnography. Conclusion: We presented the 24-hour polysomnographic findings of a case of agrypnia excitata in Morvan syndrome. An extended polysomnography, however, might be helpful in analyzing sleep disturbances in Morvan syndrome.
