Relationship between Metabolic Syndrome and Cognitive Functions in Patients with Chronic Schizophrenia

만성 조현병 환자에서 대사증후군과 인지기능과의 연관성

Objectives : The aim of this study was to investigate the relationship between metabolic syndrome and cognitive functions among chronic schizophrenia patients. Methods : The survey participants were 105(40 metabolic syndrome and 65 non-metabolic syndrome) chronic schizophrenia patients at Yang-san Hospital. Each score of cognitive test(A Korean version of the Consortium to Establish a Registry for Alzheimer's Disease Assessment Packet, stroop test), Positive and Negative Syndrome Scale, Hamilton rating scale for Depression were assessed. Statistical analysis of the relationship between various tests of A Korean version of the Consortium to Establish a Registry for Alzheimer's Disease Assessment Packet and metabolic syndrome were performed using ANCOVA and logistic regression. Results : Schizophrenia patients with lower score on construction praxia were likely to be included in Metabolic syndrome group. However, there were no significant relationships in other tests between the two groups. Conclusions : This study found metabolic syndrome caused cognitive decline in chronic schizophrenia patients, especially Construction praxia. This study could be a basis to show metabolic syndrome has to be treated appropriately in schizophrenia patients and suggests the necessity of following longitudinal designed study.

연구목적 이 연구는 만성 조현병 조현병 환자에서 대사증후군과 인지기능과의 연관성을 알아보기 위해 시행하였다. 방 법 일 병원에서 입원중인 만성 조현병 환자 105명(대사증후군 40명, 비대사증후군 65명)을 대상으로 A Korean version of the Consortium to Establish a Registry for Alzheimer's Disease Assessment Packet(CERAD-K)의 인지기능 검사 항목들을 시행하였다. 결 과 대사증후군에 이환된 만성 조현병 환자들에서 구성실행 검사 항목에서 대사증후군에 이환되지 않은 군에 비해 유의하게 낮은 점수를 나타냈으며, 그 외 다른 검사항목에서는 차이점이 나타나지 않았다. 결 론 만성 조현병 환자에서 대사증후군이 구성실행 검사 항목에서의 인지기능 저하를 나타내었다. 조현병 환자에서 대사증후군의 적절한 치료가 필요할 것이며 향후 장기추적연구가 필요할 것으로 보인다.
