Schizophrenia – Mechanisms and Effects of Oxytocin on Social Cognition in Schizophrenia – Behavioral


Researchers at the San Francisco VA Medical Center (SFVAMC) are investigating the effect of the hormone oxytocin on our social thoughts and behaviors. Oxytocin, often referred to as the “love & bonding” hormone, is produced naturally in the body. In studies that gave the hormone to humans, it was found to be safe, shown to increase social skills such as understanding emotions, and no significant side effects were reported.
Schizophrenia is a neurodevelopmental disorder that often begins in adolescence and often interferes with normal social developments as youth transition into early adulthood and beyond. People with schizophrenia can have difficulties with social relationships, which can impact interactions with others.
Available treatment options for schizophrenia do not generally improve social skills and have significant side effects. This study, led by Dr. Joshua Woolley, investigates how oxytocin impacts the social skills of people diagnosed with schizophrenia.
