title: Paranoid personality disorder and the schizophrenia spectrum-Where to draw the line?
abstract: By means of a case vignette, this study explores the clinical intersection between paranoid personality disorder and other schizophrenia-spectrum illness. Even though the patient described had paramount signs of a paranoid personality disorder and was diagnosed as such, psychopathological symptoms extended considerably beyond the common concept and diagnostic criteria of the disorder. Management strategies included psychopharmacological and non-pharmacological interventions, yet psychosocial functioning permanently appeared defective. While there is a persistent need for an opportunity to distinguish the characteristic syndromal pattern of paranoid personality attributes, the case exemplifies the challenges associated with classifying some largely suspicious and distrustful eccentrics within the schizophrenia spectrum.
