Autism in schizophrenia revisited

The concept of autism is reviewed in its historical evolution. It is suggested that the Bleulerian insistence on the withdrawal component in autism contributed to the decline of its use in adult psychiatry. Phenomenology offers another approach to grasping the nature of autism as a relational (subject-outer world) phenomenon. European phenomenological psychiatry in the field of schizophrenia is introduced and its attempts to reveal the essence of autism are presented. Autism is here considered as a "loss of vital contact with reality" (Minkowski), "inconsistency of natural experience" (Binswanger), or "the global crisis of common sense" (Blankenburg). It is proposed that autism represents dysfunctional perceptual/expressive attunement to the outer world. The usefulness of this concept is briefly examined in relation to the diagnosis and etiopathogenesis of schizophrenia.
