Three of every 1,000 children have Tourette syndrome, according to the U.S. Centers for Disease Control and Prevention. The American Psychiatric Association says more than 4 million people have OCD.

"These are chronic conditions; people with OCD and Tourette's deal with it every day. Both, at their worst, are debilitating, and the anxiety is always present," said Alies Muskin, executive director of the Anxiety and Depression Association of America, in Silver Spring, Md.

Tourette syndrome and OCD can be treated with cognitive behavioral and exposure therapy, which train people to deal with their anxiety, Muskin said.
