Abstract

Neurocognitive testing commonly uses the MMSE (Mini-Mental State Examination) to evaluate the overall cognitive function of patients at outpatient clinics, but the MMSE has recently been extensively used in the SNSB II (Seoul Neuropsychological Screening Battery II) for making diagnoses. We retrospectively investigated the results of routine neurocognitive tests and the results of the blood tests of 120 elderly patients who had been referred to a South Central Medical Center from 2017 to 2018 and who had been examined at a public health center. These subjects' space-time capability was high on the sub-region of the global deterioration scale (GDS). GDS showed a significant increase as the Na decreased on the electrolyte analysis. The subjects' concentration, their language-based orientation for space and time, their memory, and their scores for the frontal lobe function on GDS showed statistically significant reductions (P<0.001) For the normal and abnormal groups according to the ALT and creatinine levels, the frontal/execute function areas showed statistically significant differences (P<0.001) as well as negative correlation between GDS and ALT (P<0.01). In conclusion, this study provides basic information to develop test items that are important for patient screening and diagnosis, and several routine blood chemistry factors provide basic information for diagnosing and assessing the status and progress of cognitively impaired patients.

신경인지검사는 외래에서 전반적인 인지기능 정도를 평가하는 MMSE (Mini-Mental State Examination)가 가장 보편적이지만, 최근에는 SNSB II (Seoul Neuropsychological Screening Battery II)를 통해 심층적으로 진단에 활용된다. 2017년부터 2018년까지 경기도 남부지역 일개 의료원에 내원한 보건소에서 정밀검사 의뢰된 노인층 120명의 통상적인 신경인지검사 결과와 혈액검사 항목을 후향적으로 조사하였다. GDS의 하위 영역의 평가에서는 시공간 능력이 높게 나타났다. 그리고 혈액 전해질 중 Na이 GDS 수준이 증가함에 따라 통계적으로 유의한 감소를 보였다. 또한 GDS 수준에 따른 집중력, 언어 시공간능력, 기억력, 전두엽 실행 기능이 통계적으로 유의한 감소를 보였다(P<0.001). ALT와 크레아티닌이 정상군과 비정상군에서 전두엽 실행 기능 영역이 통계적으로 유의한 차이를 보였다(P<0.001). 또한 GDS와 ALT는 음의 상관성을 보였다(P<0.01). 결론적으로 본 연구를 통해 선별 및 진단에 유의한 검사 항목을 개발하는데 기초정보를 제공하고, 통상적인 혈액화학검사가 인지장애 환자의 진단 및 진행에 대한 기본 정보를 제공할 것으로 사료된다.
