This paper reviews the historical origins and psychopathological dimensions of the borderline disorder. The author suggests that Kahlbaum's clinical category "Heboidophrenie", introduced in 1890, is an eligible candidate as a protoconcept in the history of latent schizophrenia and borderline disorders. In the late 1970's and 1980's, under the influence of DSM-III, latent or borderline schizophrenia split into two personality disorders: schizotype and boiderline. Some psycopathological aspects of borderline personality disorder are presented, concerning specially affective symptoms ad social interaction disruption.43165175Masterson, J.F., Psicoterapia Intensiva del Adolescente con un Síndrome Borderline (1972) El Adolescente Borderline, , Cuademos de la ASAPPIA, Ed.
