Beginning in August 2011, 14 students (13 girls and one boy) from the LeRoy Junior-Senior High School began reporting perplexing medical symptoms including verbal outbursts,
tics, seizure activity and speech difficulty. In mid-January, five days after a community meeting in which the New York State Department of Health stated their diagnosis could not be revealed publicly due to privacy concerns, two of the girls appeared on
NBC's Today Show to discuss their frustration with not getting adequate answers. The next day, Laszlo Mechtler, a neurologist treating most of the girls, was given permission to share the diagnosis of
conversion disorder and
mass psychogenic illness. Unsatisfied with the investigation's results, the girls and their parents spoke out publicly against their diagnosis, stating they believed the situation warranted further scrutiny from outside sources. Alternative medical theories were suggested, including
Tourette syndrome and
PANDAS, which Mechtler and his team ruled out.
Erin Brockovich, noted environmental activist, was called to town to investigate
environmental pollution from the
1970 Lehigh Valley Railroad derailment as a possible cause. During this time, many of the girls appeared in the local and national media, as well as posting on social media. As this happened, the illness spread to 20 individuals. Eventually, as doctors encouraged their patients to stay away from the media and the media attention died down, many of the girls' symptoms improved. By the end of the school year in June, one girl was diagnosed with Tourette syndrome, and most of the girls who received treatment for conversion disorder were healthy in time for graduation. No environmental causes were found after repeated testing around the school and surrounding areas of town. Bartholomew, Wessely and Rubin questioned in 2012 whether interaction on social media (
Facebook,
Twitter, YouTube and Internet blogs) contributed to mass
psychogenic illness when the adolescent girls reported tic-like movements. Bartholomew
et al reported twitching epidemics in the US as early as 1939, and wrote that the Leroy outbreak was the "third recorded school outbreak of conversion disorder with motor disturbances to occur in the USA since 2002", but the first in which reports of affected individuals spread via social networks. ==Notable people==
