Gelastic seizure

A gelastic seizure, also known as "gelastic epilepsy", is a rare type of seizure that involves a sudden burst of energy, usually in the form of laughing. This syndrome usually occurs for no obvious reason and is uncontrollable. It is slightly more common in males than females.
This syndrome can go for very long periods of time without a diagnosis, as it may resemble normal laughing or crying if it occurs infrequently. It has been associated with several conditions, such as <a href="/facts/Temporal_lobe/U2wLVCrg">temporal</a> and <a href="/facts/Frontal_lobe/RvokInmf">frontal lobe</a> <a href="/facts/Lesion/WJDFnyLk">lesions</a>, <a href="/facts/Tumor/K0ytzmPz">tumors</a>, <a href="/facts/Atrophy/QNxSoxDV">atrophy</a>, <a href="/facts/Tuberous_sclerosis/nKQgVa2h">tuberous sclerosis</a>, <a href="/facts/Hemangioma/tX9PUGES">hemangiomas</a>, and post-infectious foci, but mainly <a href="/facts/Hypothalamic_hamartoma/a6fzDgnP">hypothalamic hamartomas</a>.
The term "gelastic" originates from the Greek word gelos, which means laughter.
