Abstract: Personality pathology that used to be called 'psychopathy' before and currently called 'personailty disorder' is the core phenomenon in psychic pathology that deals with borderline disorders but closely relates to endogeneous disorders. Still, this disorder still remains very unclear for clinicists, especially when it comes to its etiology, pathogenesis and even clinical borders. In such cases, O. Kerbikov believed it would be reasonable to appeal to the historical side of the issue and analyze certain discussion points that have been risen as personality pathology developed. The authors of the research analyze the origin of the term 'psychopathy' and focus on Russian priorities in the history of teaching about psychopathy. In Russia, V. Kandinsky was the first to describe psychopathy. According to O. Kerbikov, besides I. Balinsky who gave a definition of psychopathy, there should have been at least three names being recalled when we speak of psychopathy. These are V. Kandinsky, O. Chechotta and I. Balinsky, each of them made their own very special contribution to the research of psychopathy. For example, O. Chechott introduced the term 'psychopathy' into judicial psychiatry, I. Balinsky promoted the term among lawyers and others and defined psychopathy as an individual clinical phenomenon, and V. Kandinsky gave an in-depth description of personality pathology.
