    Objective To investigate the adequacy of the neuropsychological test battery proposed by the International Study of Postoperative Cognitive Dysfunction to evaluate this disorder in Brazilian elderly patients undergoing surgery under general anesthesia. Methods A neuropsychological assessment was made in patients undergoing non-cardiac surgery under general anesthesia, aged over 65 years, literate, with no history of psychiatric or neurological problems and score on the Mini Mental State Examination at or above the cutoff point for the Brazilian population (>18 or >23) according to the schooling level of the subject. Eighty patients were evaluated by a trained team of neuropsychologists up to 24 hours before elective surgery. Results Among the patients evaluated, one was excluded due to score below the cutoff point in the Mini Mental State Examination and two did not complete the test battery, thus remaining 77 patients in the study. The mean age was 69±7.5 years, and 62.34% of the subjects had ±4 years of study. The subjects had significantly lower averages than expected (p<0.001) for normative tables on neuropsychological tests. Conclusion The study demonstrated the applicability of the instruments in the Brazilian elderly and low schooling level population, but suggested the need to determine cutoff points appropriate for these individuals, ensuring the correct interpretation of results. This battery is relevant to postoperative follow-up evaluations, favoring the diagnosis of postoperative cognitive dysfunction in patients undergoing different types of surgery and anesthetic techniques.

    Lower educational level is a possible risk factor for postoperative cognitive dysfunction after surgery under general anesthesia

    Introduction: Elderly patients with postoperative cognitive dysfunction (POCD) have an increased risk of mortality, especially after major surgery1. High educational level is regarded as a protective factor for developing dementia, especially Alzheirmer's disease2, but little is known about educational level in the development of POCD. Objective: This study aims evaluating the influence of the level of education in the incidence of POCD in elderly patients undergoing surgery under general anesthesia. Methods: Seventy one patients older than 60 years old undergoing surgery under general anesthesia were evaluated before surgery and on 7th postoperative (P.O.) day by TICS (Telephone Interview for Cognitive- Standardized, instrument that assesses by telephone the skills of spatial and temporal orientation and memory, requiring only the ability to verbal understanding). Low educational level (LEL) was defined as 4 or less years of formal education and high educational level (HEL) was defined as 8 or more years of formal education. Statistical analysis was performed with SPSS 17.0, using nonparametric analysis of ordinal data with repeated measurements. P values inferior to 0,05 were considered significant. Results: HEL and LEL groups presented different TICS values since preoperative period (P = 0.032). For comparison between pre and postoperative period, the HEL group presented TICS values of 29.8±5.9 before surgery and 29.0±7.3 at 7th P.O. and for LEL group the TICS values were 17.6±3.1 and 16.7±2.6, respectively, without difference between groups (P = 0.07). Conclusions: The differences in the TICS values observed since the preoperative period are normal for the educational levels evaluated3. Although the decreasing of mean TICS value of the LEL group (5.11%) was greater than the HEL group (2.68%), the sample size analyzed wasn't enough the prove that low educational level is a risk factor for POCD.
