Perception and sensory Integration in the early phases of psychosis

Objectives

The project aims to compare the basic and integrated visual and auditory processing in early stages of psychosis (Clinical High Risk for Psychosis CHR-P and First Episode Psychosis FEP). We will explore the auditory and visual sensory processing to investigate three dimensions:
- understanding of the pathophysiological mechanisms of psychosis using the two sensory processes as models of information processing;
- implication of sensory processing in symptomatology such as sensory distortions or hallucinations;
- use of sensory processing as a potential marker of the risk of progression to psychosis. One-year follow-up of individuals with CHR-P will allow us to evaluate which sensory dysfunctions predict the progression of psychosis.

Keywords

psychiatry, psychosis, sensory, temporal, behavior, schizophrenia

Expected results

We hypothesise the existence of basic perceptual disturbances in early stages of psychosis, in relation to sensory distortions and independently of medication.
