PAREDES-ARAGON, Elma et al. Nocturnal frontal opercular seizures masquerading as catathrenia: a case report and review of the literature. Rev. mex. neurocienc. [online]. 2024, vol.25, n.3, pp.82-89.  Epub 15-Oct-2024. ISSN 2604-6180.  https://doi.org/10.24875/rmn.23000069.

A 33-year-old man with two bilateral tonic-clonic seizures of unknown onset 12 years earlier was admitted to our epilepsy monitoring unit for characterization of his nocturnal groaning spells suspicious for catathrenia. Video-scalp electroencephalogram (EEG) was suggestive of drug-resistant non-lesional localization-related focal epilepsy in the right hemisphere. Intracranial EEG showed right frontal opercular origin of seizures with insular spread as the cause of his spells. This illustrative case shows the importance of video-EEG monitoring to distinguish nocturnal frontal opercular seizures from catathrenia. We review the evidence on distinguishing the two disorders.
