A health department spokesperson says the students are being treated by their own physicians. The spokesperson says the environent and/or infection are not the cause of the symptoms.

In late 2011 and early 2012, more than a dozen Leroy students exhibited symptoms that mirror Tourettes Syndrome. The story garnered national attention and prompted the school district to conduct soil and water tests around the school. Those tests turned up nothing conclusive.

The State Health Department later suggested the cause to be an ailment known as conversion disorder.

The health departments said those students eventually stopped showing symptoms.

The school district says it is not commenting further for fear the attention could serve as a catalyst for additional cases.
