Fever, Brain Damage May Have Caused Teenager's Uncontrollable Laughter

The parents of a Chinese teenager are searching for a way to cure their daughter of an unusual ailment.

Xu Pinghui began laughing when she developed a fever at the age of 8 months, and 12 years later, she has not once stopped, Asian News International reported.

Xu cannot speak. She communicates with varying forms of giggle.

Doctors think the frontal lobe of Xu’s brain may have been damaged by the fever, which caused the mysterious laughter.

An upcoming CAT scan may provide more answers for Xu’s family.
