In a similar fashion, reduced oxytocin levels may sustain the premorbid social functioning patterns (distrust, social withdrawal and isolation) displayed by children and adolescents who go on to develop psychotic disorders, significantly depriving them of mutually beneficial interpersonal interactions that promote the development of social cognition (Fonagy and Luyten, 2009; Vrtička et al., 2014). This evidence concerns the gene OXT and psychotic disorder.
