The atypical form of Pantothenate Kinase-Associated Neurodegeneration (PKAN) tends to present at around the age of 14 years, has a heterogeneous presentation with extrapyramidal symptoms, and approximately one third of patients exhibit psychiatric problems. This paper reports the case of a patient with apparent typical symptoms of Tourette syndrome. However, the severity and poor response to treatment led to further investigation and the diagnosis of PKAN as a secondary cause of Tourettism was reached.

Tourette syndrome (TS) is associated with dysregulated cortico-striatal-thalamo-cortical neural circuitry, of which the primary implicated neurotransmitters include dopamine, glutamate, and gamma-aminobutyric acid. Pharmacologic intervention for tics should be considered when tics are causing psychological, functional, or physical impairment, and behavioral treatment is either inaccessible or ineffective. Only 3 medications have Food and Drug Administration approval for TS, including 2 typical antipsychotics (pimozide and haloperidol) and 1 atypical antipsychotic (aripiprazole).

This article provides an overview of evidence-based behavior therapy for Tourette syndrome (TS) in children, adolescents, and adults. First, this article describes evidence-based behavioral therapies for TS, examines their efficacy in randomized controlled trials, and identifies extant limitations. Second, based on the identified limitations, this article presents future directions for further research on behavioral therapies for TS.
