Official title
The Relationship Between the Efficacy of Lumateperone and Central Glutamate and Dopaminergic Metabolism: A Comparison With Risperidone in First Episode Psychosis
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will examine the differential relationships between antipsychotic efficacy and changes in dopaminergic and glutamatergic brain metabolism in lumateperone and risperidone treated early psychosis patients. Baseline glutamate and dopamine brain scans, and symptom severity measures will be collected, followed by repeated measures at 6 weeks. Half of the early psychosis patients will be treated with lumateperone, half with risperidone. Healthy control subejcts will also be examined once.
