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.
