The doctor–patient relationship is special as it addresses issues directly related to dignity and intimacy. Patients share information about their problems and, in turn, the doctor has the knowledge and skills that can help to solve these problems. It should be noted, however, that there is a clear disparity in this relationship: at some point the patient must trust the doctor and comply with the proposed instructions. As a result of this imbalance, the notion of patient rights was developed. It was pointed out that patients should be treated in a manner respectful of their dignity. This has resulted in an increasingly popular approach, according to which the patient has become a partner in the therapeutic process. In recent years, however, a disturbing phenomenon may be observed. Some patients have changed their attitude to doctors, regarding them exclusively as specialists in a given field. The expectations and demands of patients have increased and are sometimes accompanied by verbal and/or physical aggression. Therefore, some important issues that arise at this point: Does the occurrence of aggressive behaviour stem from a specific cause? Perhaps only a certain group of patients are likely to show this type of behaviour? Is it possible to become addicted to aggression? How should doctors react to verbal and/or physical violence?
