Purpose: to describe characteristics and clinical evolution of Epilepsy in patients with gelastic seizures and hypotalamic hamartoma. Methods: ten patients observed between 1986 and 1998 with onset of the epileptic disorder and/or the most relevant element of seizure semeiology characterized by typical laughing attacks. Selection criteria included EEG or Video-EEG and MRI study. Results: five patients were affected by Symptomatic Localization Related Epilepsy, related to a hypotalamic hamartoma. This epileptic syndrome was usually drug-resistant. Two patients were surgically treated with good efficacy on seizure frequency. None of five patients presented precocious puberty. Conclusions: We confirm that the frequent finding of hypotalamic hamartoma in gelastic seizures. However, gelastic seizures may also be observed in patients without MRI lesions and with normal neurological status. In these patients clinical and EEG seizure semeiology is similar to symptomatic cases, but clinical evolution is usually more benign.
