Faciobrachial motor seizures: A more apt description?

ABSTRACT: Autoimmune encephalitis associated with antibodies against leucine-rich glioma inactivated protein (LGI1) is classically associated with brief, recurrent, contractions of facial and upper limb muscles, typically on the same side. Commonly described as 'faciobrachial dystonic seizures' (FBDS), these seizures have become the semiological hallmark of anti-LGI1 encephalitis. However, the facial and upper limb contractions observed in patients with anti-LGI1 encephalitis associated seizures are not always dystonic in nature. Here, we briefly highlight the case of a patient who was admitted to our institution with faciobrachial tonic-myoclonic seizures to emphasize the fact that faciobrachial seizures in anti-LGI1 encephalitis are not always dystonic. We also review the literature on the semiolo
