Ictal Forced Repetitive Swearing in Frontal Lobe Epilepsy: Case report and review of the literature

Abstract

SUMMARYIntroduction.Dominant presentation of ictal forced repetitive swearing has been rarely addressed and could be misdiagnosed.Case report.We report a 45-year-old man with a long history of right frontal lobe epilepsy (FLE) who developed forced repetitive swearing during hypermotor seizures. His seizures were refractory to different antiepileptic drugs (AEDs). Scalp video-EEG telemetry suggested a right frontal epileptic focus. Magnetic resonance imaging (MRI) suggested focal cortical dysplasia (FCD) in the right mesial frontal lobe. Intracranial implantation with video-EEG recordings confirmed seizures originating from the MRI lesion. Patient underwent right frontal lobe resection followed by seizure freedom in the last five years on a single AED. Neuropathology confirmed FCD type IIB.Discussion.The following aspects of the case are discussed: FLE and ictal vocalization, swearing, FLE and aggression. We emphasize the differences among ictal vocalisation, verbal automatism and ictal speech. We propose that ictal swearing might fit a verbal automatism definition.Conclusion.Ictal forced repetitive swearing can be a manifestation of hypermotor seizures in FLE and should not be misdiagnosed.
