With Tourette’s disorder, or Tourette’s syndrome, tics occur for more than one year and a patient must experience both multiple motor and one or more vocal tics. In contrast, those with provisional tic disorder have experienced symptoms for less than a year and symptoms may only include single vocal or motor tics, though they may experience multiple versions of each, as well. If the tics continue, provisional tic disorder may be reassessed and the patient may be diagnosed with Tourette’s syndrome or persistent motor or vocal tic disorder.
