Psychogenic gelastic seizures in a patient with hypothalamic hamartoma

Gelastic seizures are classically associated with hypothalamic hamartoma. The most effective treatment for gelastic epilepsy is surgery, although confirming that a hypothalamic hamartoma is an epileptic lesion prior to surgical intervention is challenging. Here, we report the case of a patient with a hypothalamic hamartoma who was diagnosed with psychogenic non-epileptic gelastic seizures using video-EEG monitoring. [Published with video sequences].
