  • Abstract
  • Look Inside

The author presented 22 cases of epileptic chi-ldren whose attacks were accompanied by abnor-mal laughter or smile expression. The epilepticnature of laughter was suspected by the follow-ing reasons.

(1) Its onset was abrupt and involuntary,and frequently accompanied by convulsive seizu-res.

(2) The patient was unconscious and amne-stic about his laughter spells.

(3) The anticonvulsants might be effectivefor the control of laughter as well as convulsiveseizures.

The clinical type of epilepsies which was fre-quently accompanied by laughter was the massivemyoclonic seizure of infancy (68%).

The extensive review of literature revealedthat the hypothalamus, especially the posteriorpart of it, is important for the production andcontrol of laughter movement. But in some ca-ses, the focal lesions were found in the pons,crus cerebri, capsula interna, temporal or frontalcortex, and especially the rhinencephalon.
