Introduction

The occurrence of a first episode-psychosis in adolescents or young adults represents a difficult struggle with an uncertain and divergent outcome, since the clinician does not have at his disposal the clinical elements sufficient to predict these different disease trajectories.

Objectives

Our aims are to describe the socio-demographic, clinical characteristics and the short and long-term outcomes of a first episode-psychosis and to identify the predictive factors of the transition to schizophrenia.

Methods

We conducted a retrospective study about 117 patients hospitalized for a first episode-psychosis in the Psychiatric Department of Monastir (Tunisia). Sociodemographic and clinical features were collected using a pre-established form.

Results

First-episode psychosis affected young male subjects with low educational level. Stressors were present in 54.7%. An 8-week prodromal phase preceded the onset of the disorder in 59%. The disorder course included diagnosis of: Brief psychotic disorder (32.5%), schizophrenia (31.6%) and bipolar disorder (18.8%). The short-term outcome was characterized by a complete remission rate of 58.1% at 3 months and 37.6% at 6 months. The long-term outcome was marked by a high rate of lost to follow-up: 70.8% after 5 years. The transition to schizophrenia was linked to the presence of delirium of influence and the absence of favorable course at 3 months.

Conclusions

Our results led to the identification of the profile of patients with a first episode-psychosis and the factors correlated with a diagnosis of schizophrenia. Indeed, the determination of risk factors would make it possible to adapt earlier the care.
