Possession is regarded as one of the rare psychiatric syndromes. It was observed recently that it is one of the commonest problems that psychiatrists face. The aim of this study was to direct the attention to the size of this problem, the harm of what is called Exorcism and who is responsible for spreading this belief. 1000 patients consulting the primary mental health care clinic had been told to have possession and received treatment (Exorcism) for it, but in vain. Results revealed that females consulted more than males (58% and 42%, respectively. The commonest age affected (20-39 yrs) was 64%. Two-thirds suffered from psychoses; however, sociodemographic factors varied. Aggressive type of treatment was used which resulted in death of two patients. There is an urgent need to educate the public about the dangerousness of such beliefs and about the role of psychiatric methods used in disease management.
