Psychosis in personality disorders
Psychotic presentations are discussed in context of ten personality disorders (PDs). The PDs were examined across the literature for associations with psychosis. Hallucinations and delusions are often symptoms of paranoid, schizoid, and schizotypal PDs. Patients with borderline PD present with both auditory and visual hallucinations, and range of delusional thinking. Hallucinations are generally absent among patients with antisocial, histrionic, and narcissistic PDs. Various delusions, however, are common symptoms of these disorders. Patients with avoidant, dependent, and obsessive-compulsive PDs present with delusional thinking, olfactory hallucinations (in cases of avoidant, obsessive-compulsive PDs), and possibly tactile hallucinations (in cases of avoidant PD). Approaching PDs from multiple disciplines across neurobiological and cognitive behavioral domains could further inform treatments of psychosis in PDs. Exploration of transdiagnostic domains of emotion, cognition, motivation, and social behavior could provide vital information for diagnostic and clinical purposes. More investigation is needed to draw further associations between psychosis, PDs, and co-occurring conditions.
