Death from laughter

Infarction of the pons and the medulla oblongata in the brain may cause the pseudobulbar affect.

[3] Asphyxiation caused by laughter leads the body to shut down from the lack of oxygen.

Gelastic seizures can be due to focal lesions to the hypothalamus.

[8] Depending upon the size of the lesion, the emotional lability may be a sign of an acute condition, and not itself the cause of the fatality.

Chrysippus allegedly died of laughter after witnessing a donkey eating his figs. [ 1 ]
