Abstract

This article begins with a case of a 10-year-old autistic child, who exhibits unpredictable laughter for no obvious reason, to the embarrassment of his parents, especially when the family is in the public area. What is known as the Joker’s Laughter Complex - a form of psychological complex - is a rarely understood condition of pseudobulbar affect (PBA).
