Overview

Introduction and aim: Perioperative neurocognitive disorder stands for impairment in cognitive function in preoperative and postoperative period. Introduction of diagnostic and evaluation of cognitive function into clinical practise came to the fore because of increasing number of geriatric patients. The main goals were fast patient’s recovery after surgery and maintaining quality of life. Nowadays there are no standardized or recommended tests for evaluation cognitive function for perioperative neurocognitive disorder. Main aim of this work is to inform about first results of pilot study which is evaluating cognitive function before and after surgery.

Methodology: Pilot study evaluates cognitive functions before and after operation in patients above 65 years old with three tests. These tests are Mini Mental State Exam (MMSE), clock drawing test and TEGEST test.

Results: 36 patients were included in the study, 25 of them finished testing after operation. The test results were divided into 4 categories according to Mini-Mental State Exam to normal range, mild, moderate, and severe dementia. The highest number of patients were in normal range (14), where the results of clock drawing test didn’t correlate in with the results of other two test in half of the cases. In category mild dementia were 9 patients, in 1 patient result of clock drawing test didn’t correlate with other two tests In terms of time suitable for clinical practise could be TEGEST test and clock drawing test, MMSE seems to be time consuming for preoperative evaluation.

Keywords:

MMSE – seniors – cognitive deficit – clock drawing test – TEGEST test
