Study Summary

This study seeks to examine the effects of D-cycloserine augmentation on cognitive remediation for patients diagnosed with schizophrenia. We will test the hypotheses that D-cycloserine will significantly improve cognitive performance, negative symptoms, and measures of functioning compared to placebo when combined with eight weeks of cognitive remediation. We expect that these effects will persist when assessed at six-month follow up.

Primary Outcome

Change of a composite score from baseline to week 8 on the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS). The MATRICS consists of 10 cognitive tasks that are used to calculate scores in 7 cognitive domains: speed of processing, attention/vigilance, working memory, verbal learning, visual learning, reasoning and problem solving, and social cognition. The raw scores on each cognitive task are transformed on a normative scale into t-scores, and then these scores

Interventions
