Psychotic spectrum disorders: Definitions, classifications, neural correlates and clinical profiles

Abstract

The psychotic spectrum is the category that groups together a series of disorders linked to a symptomatology in which we witness the fragmentation of the plane of reality until it is completely broken. According to the DSM-V nosography, the disorders under examination are schizophrenia, delusional disorder, paranoid disorder, schizoid disorder, schizotypic disorder, schizoaffective disorder, brief psychotic disorder, psychotic break and catatonia. In this work, theoretical and practical profiles were analysed, paying attention to neurobiological content and therapeutic profiles, both psychotherapeutic and psychopharmacological. A note of disappointment has been made in the nosographic categorisation of dissociative disorders that currently would not be included in the psychotic spectrum disorders, although from the elements that emerged it would be interesting to revise them, precisely because of the clinical nature of the psychopathological category.
