The author questions the specificity of the treatment of adolescents through a clinical case:Ê An analyzed child asks to resume treatment at adolescence. Such a request is examined mainly from the point of view of the dynamics of both transference and counter-transference giving both situations a quite different angle. The aim of such a paper is to contribute to a bettering of adolescent psychoanalysis and to cast a new light on both analogies and differences with child analysis.
