    Abstract:
    A 65-year-old woman presented with three "convulsive" events that were preceded by stabbing pain extending from the left submandible zone to the neck and ipsilateral ear. Video-electroencephalography captured a typical attack, where electrocardiography showed bradycardia for 17 seconds and asystole for at least 9 seconds. The patient lost consciousness while her head/gaze turned right. She then manifested tonic extension of her left limbs followed by adduction of her left limb and flexion of her right upper limb. Her gaze deviated upward and her left upper limb manifested swimming-like automatisms. The full episode lasted about 70 seconds, and the EEG showed progressive diffuse high-amplitude slowing. A diagnosis of convulsive syncope resulting from classic glossopharyngeal neuralgia was made. Carbamazepine led to steady remission. Glossopharyngeal neuralgia is a rare condition (incidence of 0.7/100.000/year), whereas the occurrence of syncope is about 20%, and that of convulsive syncope is about 5%.
