First published in 1950, La nevrose d'abandon was and still is a ground-breaking work. The author's research turns on two clinical observations: the frequent occurrence of analysands whose neurotic symptoms are unrecognizable when measured against any of the Freudian diagnostic models, and the relatively large number of these patients who sought help from her, having already undergone thorough classically Freudian treatments with analysts whose abilities were never in question, but whose efforts did nothing to relieve patient suffering. What all these subjects had in common, the author observed, were extme and debilitating feelings of abandonment, insecurity and lack of self-worth, originally ignited by severe pre-oedipal trauma. Having described the neurosis of abandonment, The author goes on to outline every diagnostic tool and treatment methodology, developed over many years, which can be deployed in the successful and lasting eradication of this pervasive neurosis.
