title: [The Psychotic Thinking of Patrick Bateman].
abstract: BACKGROUND
  Literature is an inexhaustible source of study regarding mental illness which allows the academic exercise, whether dynamic oriented or not, that may help to understand the patient's inner world in the psychiatric clinical practice.
  
  
  OBJECTIVE
  Freudian, Post-Freudian and analytical examination of the main character in the U.S.A. novel AMERICAN PSYCHO.
  
  
  METHODS
  Review of sources and relevant theoretical currents.
  
  
  CONCLUSIONS
  Analysis highlights the official nosologic classification boundaries, for conditions where symptoms are scattered across the spectrum of personality disorders and psychosis spectrum; usefulness and applicability of psychoanalytic concepts in psychiatric practice are also pointed out, thus granting flexibility to the clinical approach in order to justify its use.
