Primary
| Measure | Time frame |
|---|---|
| Main Objective: To demonstrate that patients with a first episode of non-affective psychosis, who have followed antipsychotic treatment for 12 months, who already show remission criteria, and who continue with antipsychotic treatment for 12 more months, show the same risk of relapse (measured by PANSS and ICG) that patients with the same medical condition who follow a discontinuation treatment scheme based in the presence of prodromes;Secondary Objective: 1. To evaluate the differences among the two treatment arms, after 12 months from the intervention, in cognitive performance, level of functioning (WHO-DAS, performance at work/school), life quality or readmission. 2. To identify at the time of intervention the clinical charasteristics, functional recovery status, and cognitive features of patients that will benefit from the therapeutic strategy of discontinuation.;Primary end point(s): Clinical relapse (measured by PANSS and ICG);Timepoint(s) of evaluation of this end point: Every two weeks, during the first six months after initiation of treatment discontinuation/continuation. Every four weeks during the remaining six months, to complete a total follow-up scheme of 12 months. | — |
