The paper presents different approaches to personality disorders. The authors critically discuss the contemporary categorical psychiatrie (medical) classification and also present psychological approaches with the special attention put to personality trait theories and stemming from them the Five Factor Model (FFM). Due to the coming time of the publication of a new revision of the American classification DSM- 5 the detailed description of the proposals for the new system has been presented. The authors included the most updated version which has just recently been published on the DSM-5 APA web site on 11th June 2011. The proposed changes go forward to the voices of critique of present solutions, and create a hybrid system which will incorporate some elements of the dimensional approach to personality disorders.
