Is the Current Diagnosis of Schizophrenia Useful or Harmful?

Abstract

In recent decades, evidence has appeared in various scientific fields—genetic, psychopharmacological, neuro-psychological, etc.—which makes it difficult to maintain the positive and negative syndrome of schizophrenia under one and the same diagnosis. On the other hand, there are social and legal reasons recommending the con-ception of these two syndromes as different entities. In this paper, we conduct appropriate bibliographical re-searches to reveal these evidences. We discuss these findings and conclude proposing the split of positive and negative syndromes of schizophrenia in two different disorders.
