n this study, we presented a patient with gelastic seizures after subaracnoid hemorrhage. Stiff neck was detected in a 25 year- old young woman who was suffering from acute loss of consciousness. Brain tomography imaging showed subarachnoid hemorrhage and angiography revealed arterio-venous malformation on left posterior parieto- occipital region. She experienced short (30-50 second) laughing and craying episodes without cheerfulnes after 3 year of the operation. And EEG revealed an active epileptic activity on left fronto-temporal region. Clinical and laboratory findings were consistent with gelastic epilepsy that originate from frontal lobe. Seizures were controled with carbamazepine monotherapy.
