[Drug-induced dystonia misinterpreted as hysteria].
Psychic distress is often expressed in the form of physical pain or disease, but the converse also occurs. Illnesses with an organic aetiology are sometimes misdiagnosed as psychogenic. We describe three patients who developed rare forms of acute drug-induced dystonia when treated with antipsychotic drugs. All three cases were initially misdiagnosed as "hysteria" because the patients had psychiatric illnesses and because the symptoms were bizarre and became worse when the patients became very anxious. Furthermore, if the patients were helped to relax the symptoms disappeared for a moment. One of the patients developed dystonia 24 hours after ingestion of 750 mg tetrabenazine in an attempt at suicide. Another patient who had HIV/AIDS developed severe dystonia after receiving only 2 mg haloperidol by mouth. The clinical presentation, treatment, and possible mechanisms of the pathophysiology of acute drug-induced dystonia are briefly reviewed.
