Given the recalcitrant nature of cognitive deficits in schizophrenia & their impact on functional capacity we felt that in designing a study to test the effectiveness of cognitive remediation we should maximize the likelihood of therapeutic benefit by administering cognitive remediation in the context of pharmacotherapy that may have potential for precognitive effects. By so doing we could possibly boost the effect sizes seen with cognitive remediation alone. In this study we will transition patients with schizophrenia (in whom a change in antipsychotic therapy is clinically warranted) from their current antipsychotic to lurasidone - clinicians will have eight weeks to complete the switch. Subjects who are successfully switched to lurasidone will then be randomized to receive either cognitive remediation or a non-specific mental activity control condition two times/week for a total of 30 sessions over a 4-6 month period. Our goal is to have 140 patients complete the cognitive remediation phase.
