Movements disorders are frequently encountered in general practice and emergency departments and are in many cases of iatrogenic origin. Dopamine D2 receptor blocking agents (DRBA), mainly neuroleptics, are most often incriminated. These drug-induced movement disorders (DIMD) can be classified according to the kinetics of the manifestations (acute DIMD and tardive syndromes), the phenomenology of the abnormal movements observed or depending on the pharmacological agent involved. The diagnosis is based on the time course of the events, clinical examination and meticulous anamnesis of the patient's previous and current treatments. Management is always based on the interruption of the suspected causal treatment when possible. Some cases have a severe prognosis and require immediate treatment.
