A bizarre illness affecting nearly 20 students at a Western New York Junior-Senior High school now has an official diagnosis: mass hysteria.

The students, almost all of them girls, and mostly friends, began experiencing involuntary jerks and tics. Sometimes their limbs, neck or face would suddenly spasm; other times they would twitch, grunt, or shout. It was strange and troubling behavior, made all the more scary because it had no clear cause.
