After 7% to 26% of non-cardiac procedures, Postoperative Cognitive Dysfunction (POCD), a temporary impairment of memory, concentration, and information processing, has been documented with an increase in morbidity and mortality. The identification of POCD risk factors was our secondary goal. Prospective cohort study of women under 60 who will undergo surgery for pelvic organ prolapse. History of cognitive impairment, a serious neurologic condition, and an abnormal cognition screen were all exclusion factors. An extensive Neuropsychological (NP) battery (eight tests), given two weeks before and after surgery, evaluated premorbid IQ and the executive function, attention, and memory domains. Decline of 1 SD on 2 NP tests or decline of 2 SD on 1 test was the primary outcome. Z-scores were created by converting raw scores.
