Objectives It was the aim to examine the association of the thyroid-related hormones with cognitive function, depression, and subjective memory impairment in community-dwelling elders with questionable dementia. Methods The sample consisted of 399 community residents with 'questionable dementia' aged 60 or over in whom serum thyroid-related hormones [thyroid stimulating hormone (TSH) and thyroxine] had been assayed. Cognitive impairment was defined using the Korean version of the Consortium Establish a Registry for Alzheimer's Disease. Depression was diagnosed using the Korean version of Geriatric Depression Scale and subjective memory complaint (SMC) was checked using the subjective memory complaints questionnaire (SMCQ). Age, gender, education, and the presence of apolipoprotein E {\varepsilon}4 were included as covariates. Results There was a significant positive association between verbal fluency test (VFT) score and serum TSH levels (p = 0.01). There was a significant negative association between SMCQ total score and word list memory test (WLMT)(p = 0.002) or word list recall test (WLRT) score (p = 0.013). Conclusions Lower serum TSH levels were associated with semantic memory (VFT), and we found that SMC was associated with episodic memory (WLMT and WLRT) in this sample.

본 연구에서는 주관적인 기억력 저하를 호소하는 환자의 인지기능 특성에 대해 알아보기 위해, 2005년 3월 1일부터 2009년 5월 31일까지 영남대학교 의료원 건강검진 센터를 방문한 대상자들 중 주관적인 기억력 저하를 호소하는 155명을 대상으로 인지평가참고 진단시스템 (CARDS)을 실행하였다. 대상자 138명 중 정상은 107명(약 78%), 치매 21명(약 15 %), 10명(7 %)은 우울장애, 불안장애, 적응장애 등의 정신과적 환자로 진단되었다. CARDS의 6개 소검사 중 기억력, 실인증, 실어증, 집중력과 계산력, 고위수행 불능증에서는 WNL군에 비해 DEM군, PSY군이 유의하게 낮은 수행을 보였다. 한편, 실행증에서는 DEM군이 PSY군과 WNL군에 비해 낮은 수행을 보였다. 기억력 저하 증상을 호소하는 환자들은 치매 초기와 다른 정신과 질환 이환의 가능성이 있으므로, 민감도가 높은 치매 선별검사와 정신과적 조기 진단이 필요할 것으로 보인다.

Objectives The purpose of this study is to evaluate the relationship between the severity of white matter changes (WMC), risk factors and cognitive domains, including executive function profiles. Method Forty nine subjects over 55 years with subjective memory complaints were assessed with MRI and neuropsychological tests. The WMC were assessed by MRI T2-FLAIR images and divided into 3 groups of mild vs. moderate vs. severe and 2 groups of mild-moderate vs. severe by using Mantyla's criteria and Fazeka's criteria. The risk factors were examined in hypertension, heart disease history and chemistry Lab. Medical conditions which affect to cognitive dysfunction and definite dementia were also excluded. Results Comparing 3 groups, hypertension was identified as a risk factor of the WMC. Comparing 2 groups, total cholesterol and LDL were identified for as the risk factor of WMC. The severity of WMC was significantly associated with cognitive disturbances and their main effect on cognition was working memory and inhibition. Conclusion The risk factors of the WMC in the elderly were hypertension, hyperlipidemia. The severity of WMC appears to be associated with executive dysfunction in the elderly.

Objectives Non-major depression with fewer symptoms than required for a Diagnostic and Statistical Manual of Mental Disorders-4th edition diagnosis of major depressive disorder (MDD) has consistently been found to be associated with functional impairment. In this study, we aim to estimate the cognitive impairment and the quality of life in elderly patients with subsyndromal depression (SSD) compared with non-depressive elderly (NDE). Methods The Korean version of Mini International Neuropsychiatric Interview was administered to 194 outpatients with depression and 108 normal controls. SSD is defined as having five or more current depressive symptoms with core depressive symptoms (depressive mood or loss of interest or pleasure) during more than half a day and more than seven days over two weeks. Depression was evaluated by the Korean form of Geriatric Depression Scale of a 15-item short version. Global cognition was assessed by Mini-Mental State Examination in the Korean version of CERAD assessment packet (MMSE-KC). Subjective cognitive impairment was assessed by the Subjective Memory Complaint Questionnaire. Quality of life was evaluated by the Korean Version of Short-Form 36-Item Health Survey. Results The mean score of the MMSE-KC in the SSD group was lower than that in the NDE group with adjustment for age, gender, and education [F = 4.270, p = 0.04, analysis of covariance (ANCOVA)]. If we defined those having Z-score of MMSE-KC < -1.5 as a high risk group of cognitive impairment, the odds ratio for the high risk group of cognitive impairment was 1.86 [95% confidence intervals (CI) 1.04-3.34] in SSD and 7.57 (95% CI 3.50-16.40) in MDD compared to NDE. The scores of physical component summary (F = 9.274, p = 0.003, ANCOVA) and mental component summary (F = 53.166, p < 0.001, ANCOVA) in the SSD group were lower than those in the NDE group with adjustment for age, gender, and education. Conclusions The subjects with SSD, as well as those with MDD, showed impairment of global cognition and also experienced low quality of life in both physical and mental aspects, compared to the NDE group.
