Abstract
Oxytocin is a neuropeptide known to affect social behaviour and cognition. Craniopharyngioma patients are considered to have an oxytocin-release-deficit caused by a rare tumour affecting the pituitary and/or the hypothalamus relevant for oxytocin production and release. To assess social behaviour and socio-cognitive abilities in this patient group, we tested 13 patients and 23 healthy controls on self-report questionnaires and an eye-tracking paradigm including fast facial emotion recognition. Additionally, saliva oxytocin levels acquired before and after a physical stress induction were available from a previous study, representing the reactivity of the oxytocin system. The data revealed three major results. First, patients with an oxytocin-release-deficit scored higher on self-reported autistic traits and reduced levels of hedonia for social encounters, although they showed no impairments in attributing mental states. Second, patients showed more difficulties in the fast emotion recognition task. Third, although automatic gaze behaviour during emotion recognition did not differ between groups, gaze behaviour was related to the reactivity of the oxytocin system across all participants. Taken together, these findings demonstrate the importance of investigating the reactivity of the oxytocin system and its relationship with social cognition. Our findings suggest that reduced emotional processing abilities may represent a pathological feature in a group of craniopharyngioma patients, indicating that this patient group might benefit from specific treatments within the social domain.
