Laughter can cause atonia and collapse (‘gelastic syncope,’ a short episode of low blood pressure caused by laughter), which in turn can cause trauma. Gelastic seizures, a rare type of seizure that involves a sudden burst of energy, usually in the form of laughing or crying, can be due to focal lesions to the hypothalamus.

Gelastic syncope has also been associated with the cerebellum.
