Abstract

Tics are brief, rapid and repetitive movement and sounds that are either simple or complex in presentation. Tics can be preceded by a premonitory urge (sensation) that decreases after tic is completed. The fourth edition of Diagnostic Statistical Manual of Mental Disorder (DSM- IV) includes diagnoses for Tourettes disorder, chronic motor or vocal tic disorder, transient tic disorder and tic disorder not otherwise specified (Table 1) according to the duration of tic symptoms and degree of complexity. The purposes of treatment of tic disorders must be set up based on the comprehensive evaluation of developmental profiles, strength, weakness, family situation, and school adaptation status. The family education must be included early in treatment process and psychosocial treatment including the cognitive behavioral therapy will be needed to develop and maintain the self-efficacy in controlling the tic symptoms. The most effective and efficient method for the reduction of tic symptoms, however, are drug treatment. The pharmacotherapy is usually one component of treatment for chronic tic disorder and Tourettes disorder. The gold standard”for tic reduction is the dopaminergic receptor blocking agent (or antipsychotic agent, neuroleptics). The primary drugs are haloperidol, pimozide, and risperidone. Among theses, risperidone will be the primary choice because of its low side effect profiles, esp, neurologic side effects. In the near future, the studies on the efficacy of the olanzapine, quetiapine and ziprasidone will be more reported. As second line drugs, clionidine, guanfacine, nicotine related drugs can be considered. (J Korean Acad Fam Med 2004;25:359-370)
