Outcomes

Primary Outcome Measures

Assessment of cardiovascular risk will be realized by measurement of cytokine levels, C-reactive protein and cholesterol levels.
Assessment of cardiovascular risk will be realized by measurement of cytokine levels (IL-12p70, IL-6, IL-10, IL-1b, IL-8 and TNF-α), C-reactive protein and cholesterol levels (total cholesterol, LDL, HDL, triglycerides) in patients with schizophrenia before and after supplementation with resveratrol or placebo.

Secondary Outcome Measures

Cognitive performance will be assessed with a battery of cognitive tests and BPRS (brief psychiatric rating scale) to assess symptoms.
Cognitive performance will be assessed with a battery of cognitive tests (Hopkins, for verbal memory; Stroop: for executive function; Digits WAIS-III, for attention; and Sequence numbers and letters for verbal memory and attention) and BPRS (brief psychiatric rating scale) to assess symptoms.
