European Long-acting Antipsychotics in Schizophrenia Trial-II

Study Overview
=================
Brief Summary
-----------------
Schizophrenia is a chronic psychiatric illness with a heterogeneous disease course, varying from periods of symptomatic remission to relapse. Relative to the wealth of scientific data on the course of schizophrenia during the two years following the first psychotic episode, the outcome of schizophrenia patients over the first decade of their illness has been studied to a lesser degree. In this follow-up cohort study we aim to investigate the long-term outcome of schizophrenia patients who participated in the previously conducted EULAST-I clinical trial, in the first decade after being diagnosed.
