Olanzapine is a second generation antipsychotic agent that is used for the treatment of the psychotic disorders and mood disorders. Olanzapine is also known to have greater affinity for mezolimbic dopaminergic pathway than for nigrostriyatal dopamine pathway. As a result olanzapine is associated with significantly fewer extrapyramidal symptoms. Tardive dystonia is a rare side effect of antipsychotic treatment frequently causing twisting painful muscle contractions. Effective treatment choice for tardive dystonia is limited. The clinicians must consider acute dystonia neurological disorders and family history for differential diagnosis. Here we present a rare case of torticollis after 5 mg/day olanzapine treatment in a young female patient with psychotic disorder. [Anadolu Psikiyatri Derg 2016; 17(0.300): 8-10]
