Drug-induced movement disorders remain a common and under-recognized problem. Blockade of the dopaminergic system results in multiple syndromes and will be the main focus of this discussion. These syndromes are often referred to as extrapyramidal side effects (EPSE) and include tardive dyskinesia, acute dystonic reactions, akathisia, drug-induced parkinsonism and neuroleptic malignant syndrome (Figure 6.1). Serotonin syndrome and drug-induced tremor are also briefly discussed.
