Abstract

Background: Gelastic seizure (GS) is a rare type of epilepsy that most commonly appears in patients with hypothalamic hamartoma. It is rarely associated with other types of brain damage. This particular type of epilepsy is relatively rare and has few links to other brain lesions. Temporal lobe malacia is mostly caused by cerebral infarction or cerebral hemorrhage, which can lead to seizures. We report a case of GS in a woman with temporal lobe malacia which was reported for the first time in the literature.

Case Summary: A 73-year-old female, diagnosed case of GS, presented with repetitive stereotyped laughter a month prior to presentation, happening multiple times daily and with each time lasting for 5-15s. Electroencephalogram displayed a focal seizure seen in the right temporal region. Magnetic resonance imaging head with contrast showed a right temporal lobe malacia. The patient was started on levetiracetam daily. The patient indicated that they had fully recovered and were not experiencing any recurrent or stereotyped laughter during their daily routines. These results remained consistent even after a one-year follow-up period.

Conclusion: GS can be caused by temporal lobe malacia, which is an uncommon but potentially grave condition. The outcome of this present case exhibited the importance of the temporal lobe in the genesis of GS.
