Brief Summary
Psychosis is a heterogeneous disorder and present treatment only works for a limited number of patients. In order to identify new therapeutic targets, this study will longitudinally characterize the underlying pathologies in those with poor treatment response using complimentary brain imaging modalities.

Outcome Measures
Primary Outcomes (3)
Measures of brain structure
Measures of brain structure, as measured with diffusion tensor imaging (DTI) that are associated at baseline (when patients are unmedicated) with subsequent treatment response to antipsychotic medication.
32 weeks
Measures of brain function
Measures of brain function, as measured with functional MRI (fMRI) that are associated at baseline (when patients are unmedicated) with subsequent treatment response to antipsychotic medication.
32 weeks
Measures of brain biochemistry
Measures of brain biochemistry, as measured with MR Spectroscopy, that are associated at baseline (when patients are unmedicated) with subsequent treatment response to antipsychotic medication.

Treatment group
These participants are newly diagnosed with psychosis.
Interventions
Subjects with first episode psychosis will be treated with risperidone, the most frequently used antipsychotic drug (APD) for 32 weeks. The study will follow a rigorous longitudinal design to capture treatment response whereby those without an adequate response after 16 weeks of treatment will be switched to aripiprazole, another APD for 16 weeks. All patients will be scanned four times: at baseline and after 6, 16, and 32 weeks of treatment.
