Abstract: The role of oxytocin (OT) in social cognition of patients with Huntington’s disease (HD) has been studied, but its impact on executive functioning has not been explored yet. Healthy controls, premanifest HD, and manifest HD participants underwent executive functioning assessment and OT plasma measurement. There were no significant group differences in plasma OT levels. Higher OT levels were associated with better executive functioning in premanifest HD participants. Our findings revealed an association between OT levels and depressive symptoms in premanifest and manifest HD participants. The potential role of OT in HD deserves further investigation.
