NCT02476708

Brief Summary

This is an 8-week randomized, double-blind, placebo-controlled, parallel, fixed-dose pilot clinical trial of curcumin for the treatment of cognitive impairment in schizophrenia.The primary aim of this pilot trial is to provide an effect size estimate for the efficacy of curcumin in improving cognitive functioning in schizophrenia. Secondary goals are to determine the effect of curcumin over time on negative and positive symptoms, in association with inflammatory markers.

Outcome Measures

Primary Outcomes (1)

  • Efficacy of curcumin (MATRICS - Composite Score t score)

    The primary outcome will estimate the efficacy of curcumin in improving cognitive functioning in schizophrenia. This would be measured by comparing change in cognition scores (MATRICS Consensus Cognitive Battery Composite Score) between baseline and endpoint based on medication assignment.

    8 weeks

Secondary Outcomes (10)

  • Effect on psychiatric symptoms (PANSS - Positive Score)

    8 weeks

  • Effect on psychiatric symptoms (PANSS- Negative Score)

    8 weeks

  • Effect on psychiatric symptoms (PANSS- Total Score)

    8 weeks

  • Efficacy of curcumin (MATRICS - Speed of Processing - t score)

    8 weeks

  • Efficacy of curcumin (MATRICS - Attention/Vigilance t-score)
