Conclusion
Patients with underlying Tourette’s disorder, may present with a bewildering array of neurological and psychiatric symptoms. Careful evaluation of the overall medical status, family history and especially the response to previous trials of medications may assist the clinician in making the correct diagnosis. Lithium may prove to be of substantial value in treating patients with Tourette’s disorder who do not respond to trials of conventional medical treatment. The mechanism of action of lithium in such cases is unclear and open to postulation.
