Premorbid of depressive youth at clinical high-risk for psychosis

Abstract

Introduction

Early detection of psychosis is a promising area in preventive psychiatry. The use of early intervention can prevent the first episode psychosis and improve outcomes.

Objectives

Identification of premorbid features of depressive patients at clinical high risk for psychosis (CHR) comparing with depressive patients without CHR in order to improve early recognition of the psychotic process.

Methods

219 young depressive in-patients with CHR criteria for SOPS with attenuated positive and attenuated negative symptoms and 52 young depressive in-patients without CHR were examined. Presence of obstetric complications, neurodevelopmental deviance, neurological and psychiatric signs at the premorbid stage, and the level of premorbid functioning on the PAS were examined.

Results

It has been established that depressive patients at CHR and without CHR had some obstetric complications (57.5% and 40.4%, respectively). Neurodevelopmental deviance in the first year of live was in 57.5% patients with CHR. At the age of 3-5 sleep disorders, ADHD and phobias were more common in patients at CHR than without it (58.8% and 32.7%, p=0.014). In pubertal, patients at CHR were more likely to show depression symptoms, obsessions, and aggression - 90.4% versus 76.9% (p=0.029). On the PAS scale, a decrease of the level of premorbid functioning has been observed in two groups of patients with and without CHR from the age of 12: from 12 to 15 years, 0.4 and 0.3 (p=0.004), from 16 to 18 years, 0.47 and 0.37 (p 0.001).

Conclusions

Premorbid functioning were worst in patients with CHR, which indicates the possibility of early clinical detection of psychosis.
