Gelastic

From Wikipedia, the free encyclopedia

Gelastic is a term used to refer to a certain type of epilepsy or epileptic seizure. The seizures of gelastic epilepsy are characterized by spells of involuntary laughter. The laughter has been described as "creepy" (Chong, 2003) and "without true mirth" (Fisch, 1991).

Gelastic epilepsy often results from a developmental abnormality of the brain known as hypothalamic hamartoma.
