Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To evaluate the variations in volume of gray matter in patients with early onset psychotic episodes after 48 weeks of treatment with NAC or placebo;Secondary Objective: -To assess the changes in the concentrations of brain GSH in patients with early onset psychotic episodes before and after treatment -To assess the changes in oxidative metabolic status of patients in patients with early onset psychotic episodes before and after treatment - To Assess variations in volume of white matter in patients in patients with early onset psychotic episodes after treatment - To relate the loss of volume of gray matter in patients with early onset psychotic episodes with markers of oxidative stress. - To study markers of central and peripheral oxidative stress as possible biomarkers that can predict response to NAC. - To compare the changes in clinical and psychopathology scales (CGI, PANSS, YMRS, HAM-D) - To compare the changes in the psychosocial functioning (C-GAS, WHO-DAS) after treatment - To compare the required antipsychotic doses - To compare the frequency and intensity of adverse effects associated with neuroleptic treatment (AIMS, BARS);Primary end point(s): Volumetric changes in frontal gray matter (right over left) measured by nuclear magnetic resonance (NMR) after 48 weeks of adjuvant treatment with NAC or placebo.;Timepoint(s) of evaluation of this end point: 48 weeks | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): 1. Changes in cerebral GSH concentrations measured by spectroscopy (MRS) after 48 weeks of treatment with NAC or placebo. 2 Volumetric changes in brain white matter measured by diffusion (DTI) after 48 weeks of treatment with NAC or placebo. 3. Changes in the values of markers of oxidative metabolism after 48 weeks of adjuvant treatment with NAC and placebo in a year. 4. Changes in the score in clinical and psychopathology scales (CGI, PANSS, YMRS, HAM-D) and psychosocial functioning (C-GAS, WHO-DAS) after 48 weeks of adjuvant treatment with NAC or placebo. 5 Doses of antipsychotic and extrapyramidal side effects of antipsychotic treatment (AIMS, BARS) after 48 weeks of treatment with NAC or placebo;Timepoint(s) of evaluation of this end point: 48 weeks | — |
