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 temporal and frontal lobe lesions, tumors, atrophy, tuberous sclerosis, hemangiomas, and post-infectious foci, but mainly hypothalamic hamartomas.
