[Oxytocin: evidence for a therapeutic potential of the social neuromodulator].

Only few substances have achieved such a great prominence in recent years as the hypothalamic neuropeptide oxytocin, which is also widely known as the love hormone. Oxytocin is a potent neuromodulator which can improve social cognitive functions including empathy, trust, cooperation and social learning. However, oxytocin can also promote negative social behavior and increase poor memory and feelings of fear in social situations. Positive data from initial clinical trials give rise to the hope that oxytocin will prove to be a substance which is suitable for targeted treatment of poor social-cognitive behavior in neuropsychiatric diseases. This review article summarizes the most important recent preclinical and clinical human studies and discusses the findings presented with respect to current concepts of personal and contextual influences.
