Borderline Personality Disorder is an increasingly common condition in our society. Nevertheless, there is still uncertainty regarding appropriate therapeutic concepts due to the variety of its symptomatic manifestations and the lack of understanding of the defense mechanisms it triggers. Miriam K. Sarnecki explores the psychodynamics of Borderline Personality Disorder, as well as its causes and therapeutic options from a psychoanalytic perspective. The author illustrates the efforts individuals make to remain as functional and socially engaged as possible despite the severe psychological disorder, and she discusses analogies between Borderline Personality Disorder and today's late modern society. In a concise, comprehensible, and simultaneously nuanced manner, she sheds light on Borderline Personality Disorder and its implications.
