Tourette syndrome is a neurological disorder characterized by repetitive involuntary movements and vocalizations called tics. It was first described by French neurologist Georges Gilles de la Tourette. There are two main types of tics: motor tics which involve brief muscle movements, and vocal tics which can range from sounds to words. Treatments include medication for severe cases, but mild cases are often recommended to socialize instead of using medication, though some doctors disagree with this approach.
