Surgical treatment of extra-hypothalamic epilepsies presenting with gelastic seizures

: We provide an overview of the surgical outcome of extra-hypothalamic epilepsies with gelastic seizures based on an original case report and a summary of the literature. Twenty-two articles providing information on the outcome of resective surgery in 39 patients with extra-hypothalamic gelastic seizures from the temporal (19 patients) or frontal lobe (20 patients) were selected. We add another case of temporal lobe gelastic seizures to the literature with a video demonstrating the mirthful component of this patient's laughing seizures. Drug-refractory cases of gelastic seizures from the temporal or frontal lobes are amenable to surgical treatment following thorough investigation with imaging, as well as scalp and intracranial EEG.
