20/20: There's a Stranger Inside

An estimated one in every thousand children has Tourette syndrome, a neuro-biological disorder that is characterized by a range of symptoms ranging from painful self-abuse and rage episodes to bizarre vocalizations like barking, meowing or even vulgar and profane language. The children are helpless to control the embarrassing behavior, which subjects them to painful ridicule from their peers and sometimes even adults. For families living with this disorder, it's an unimaginable reality. Jay Schadler follows the stories of four girls and their families as they document intimate scenes from their lives in video diaries. The children poignantly discuss the most debilitating effect of Tourette syndrome, including the emotional impact of social isolation that sometimes includes alienation from their own families. Even though this mystery disorder has no known cause or cure, the girls reveal the inner strength that empowers them to achieve their dreams.
