Abstract

This study was undertaken to determine the correlation between β-amyloid, serum lipid levels, and cognitive function in the elderly with mild Alzheimer's dementia. The study was conducted in December 2018, enrolling 45 elderly people with mild Alzheimer's disease. Blood analysis measured the β-amyloid and serum lipid levels, and cognitive function was measured using MMSE-K. The correlation between β-amyloid, serum lipid levels and cognitive function was determined using Pearson's correlation analysis. A significantly negative correlation was observed between the β-amyloid level and cognitive function (p<0.05). Furthermore, serum lipid levels and cognitive function also revealed a significantly negative correlation between TC and LDL levels (p<0.05). These results indicate that increasing levels of β-amyloid, TC, and LDL augments a negative correlation that decreases the cognitive function, signifying that management of pathologic factors related to dementia is important for the prevention and improvement of cognitive function in dementia patients.

본 연구는 경증 알츠하이머 치매 노인의 베타 아밀로이드 및 혈중 지질 수준과 인지기능 간의 상관관계를 알아보고자 실시하였다. 연구의 대상자는 경증 알츠하이머 치매 노인 45명을 대상으로 실시하였다. 2018년 12월 베타 아밀로이드 및 혈중 지질 수준을 측정하기 위해 혈액 분석을 실시하였으며, 인지기능의 측정을 위해 MMSE-K 검사를 이용하여 측정하였다. 베타 아밀로이드 및 혈중 지질 수준과 인지기능 간의 상관관계를 알아보기 위해 Pearson's correlation analysis를 사용하여 분석하였다. 연구 결과 베타 아밀로이드 수준과 인지기능 간의 상관관계에서는 -.604로 유의한 음의 상관관계를 보였으며(p<.05), 혈중 지질 수준과 인지기능 간의 상관관계에서는 TC(total cholesterol)와 LDL(low density lipoprotein) 수준에서 각각 -.601, -.403로 유의한 음의 상관관계를 보였다(p<.05). 이와 같은 결과는 베타아밀로이드 및 TC, LDL 수준이 증가할수록 인지기능이 감소하는 음의 상관관계가 나타나는 것을 알 수 있었다. 이처럼 치매 환자의 예방 및 인지기능의 증진을 위해서 치매 관련 병리학적 인자의 관리가 중요하다고 사료된다.
