Vasopressin - pituitary neurohormone, in addition to the essential role of which is to regulate blood pressure and affecting the body's water balance, it is involved in other processes such as social behaviour, memory processes and learning. It also plays an important role in modulating anxiety. This hormone seems indispensable for the creation of proper social interactions, and its low plasma levels correlate with the dysfunction of interpersonal relationships. In this article, we review and summarize the studies on the role of vasopressin in the pathogenesis and therapy of schizophrenia. Despite some potential limitations in peer-reviewed studies, the literature suggests the potential role of vasopressin in the pathogenesis of schizophrenia and the possible therapeutic application in this psychiatric disorder.
