Tourette's Syndrome

Tourette's Syndrome is a neurobiological disorder characterized by tics (involuntary, rapid, sudden movements and/or vocal outbursts that occur repeatedly). The symptoms change periodically in number, frequency, type, and severity - even disappearing for weeks or months at a time. Some common examples of motor tics include eye blinking, head jerking, shoulder shrugging, and facial grimacing. Vocal tics include throat clearing, barking noises, sniffing, and tongue clicking.
