Supplemental data

Ouvrir l'onglet

Gelastic seizures are often associated with hypothalamic hamartomas. However, focal cortical dysplasias can also cause “laughing seizures”, and such cases can be difficult to localize with EEG. This case report presents a 29-year-old woman who was successfully rendered free of gelastic seizures after resection of a frontal cortical dysplasia, localized through MRI and SPECT imaging.[Published with video sequences]
