Can tourettes be a nervous system disorder?

Yes: Tourette's is classified as a neurological disorder. It can be a stand alone condition or coexist with others disorders like adhd or bipolar. Not every person with a tic has tourette's and isolated tics in children are not that uncommon. Sudden onset of tourette's can be caused by a strep throat infection and if caught early can have good resolution. Meds are often used in chronic cases.
