Psychiatry was often used for political reasons in the second half of the 20th century, especially in the former communist countries. According to the global initiative on psychiatry, political abuse of psychiatry is defined as the incorrect usage of diagnoses, treatments, or psychiatry admissions in order to limits fundamental rights of persons or population groups in certain countries. Most studies regarding political abuse as a repressive measure analysed it in either USSR or China. Romania is one of the countries from the former communist block in which psychiatry was proven to be used as a form of repression against political dissidents. One of the psychiatry “tools” used against political dissidents was the widespread usage of mandatory, non-voluntary admissions. They were seen as preventive measures, whose purpose was to prevent an individual to act antisocially. The purpose of this article is to analyse the characteristics of the patients that were non-voluntarily admitted in psychiatry hospitals, based on studies published by the forensic psychiatry researchers in the communist period. The main conclusions of this study are: (1) the presence of a disproportionate number of patients admitted with schizophrenia, especially the paranoid type; (2) patients that performed acts against the state were more often diagnosed with schizophrenia; (3) patients that performed acts against the state were more often considered to have no judicial responsibility; (4) the non-voluntary admission/treatment were more often removed for crimes against persons, and less often in crimes against the state.
