This paper proposes an investigation regarding the issue of the differential diagnosis in the context of the psychoanalytic practice. It consists of a research based on a clinical observation that refers to the operability of the structural diagnoses. It points out to a perspective in which the direction of the clinical management is not pervaded by the pre-established classificatory rigor, but by the issue of the subject in his relation with the Other, his discursive position.
Key words:
Diagnosis; psychoanalysis; structure; discursive position
