The Neuropsychiatry Unit Cognitive Assessment Tool (NUCOG) is an instrument commonly used to screen for cognitive impairment. The NUCOG remains largely unvalidated in an epilepsy surgical population despite its continued use in the epilepsy program at the Royal Melbourne Hospital and Alfred Hospital. The overall objective of this study is to investigate whether the NUCOG is a valid screening instrument for detecting cognitive impairment in epilepsy surgical patients. Specifically, we aim to determine (1) optimal NUCOG total and domain cut-off scores for this population; (2) whether the NUCOG total score is sensitive to any cognitive deficit; (3) the convergent and divergent validity of the five NUCOG domains; and (4) whether the accuracy of NUCOG depends on any clinico-demographic factors.
