The classic distinction between psychiatry and neurology is blurring in part because of a better understanding of neuropsychiatric disorders in neurological diseases. Certain structures, including the basal ganglia, are involved in both motor and behavioral processes. Parkinson's disease and Tourette's disease are good examples of these two facets. Other movement pathologies are rarer or less known. Abnormal movements are symptoms that are frequently found in psychiatry, and are most often secondary to the use of an antipsychotic treatment. However, there is no easy-to-use tool to characterize abnormal movements or to adopt an unequivocal course of action, whereas the identification of the movement, its analysis and the delay of management can condition the prognosis. Through three clinical vignettes, this work will allow us to describe semiologically the abnormal movements most frequently found in psychiatry and to propose an optimal management of these movements as soon as they occur and probably to reduce the misuse of anticholinergic treatment.
