Brain Blood Flow Changes Elicited by Oxytocin in Volunteers With and Without Schizophrenia
Withdrawn before enrolling · Not applicable · Has a placebo group
Conditions studied: Schizophrenia
In brief
The purpose of this study is to assess how oxytocin delivered intranasally changes regional brain blood flow measured by positron emission tomography (PET) in conjunction with oxygen-15 labeled water in persons with schizophrenia. The objective is to better our understanding of oxytocin's role in the modulation of social judgment in schizophrenia and provide more information as to potential uses of oxytocin or a similar drug analog in treating certain features of schizophrenia and other neuropsychiatric disorders.
