HIGHLIGHTSType of Research: Single-centre, prospective, observational study Key Findings: Among 95 unselected PAD outpatients, 25.5% had abnormal 6-CIT scores indicating cognitive impairment, despite being previously undiagnosed.No significant correlation was found between cognitive performance and mood (HADS) or delirium risk (4AT).Take Home Message: Cognitive impairment may be common and under-recognised in PAD patients.Further research is needed in this area, and routine screening may be warranted to support surgical planning and shared decision-making. Table of Contents SummaryCognitive impairment was identified in 25.5% of 95 unselected PAD outpatients in this prospective observational study.Routine cognitive screening may aid in perioperative planning and early identification of undiagnosed impairment in vascular surgical candidates.
