“…The differences in these prevalence estimates of dementia may be due to different population characteristics or differences in study methodologies, such as case-finding procedures and the diagnostic threshold for dementia [7] . Furthermore, although the two previous studies on the prevalence of dementia in urban Korean elders were conducted in the two largest metropolitan cities of Korea (Seoul [3] and Busan [2] ), the study populations were not representative of the typical urban elderly population in Korea. In particular, the level of educational attainment, one of major sources of variation in dementia prevalence, was much lower in the studied samples than among Korean urban elders in general [2,3,8] .…”

Background/Aims: We estimated the prevalence of dementia and its major subtypes in an elderly urban Korean population. Methods: A study population of 1,118 Korean elders was randomly sampled from the residents aged 65 years or older living in Seongnam, Korea. Standardized face-to-face interviews, and neurological and physical examinations were conducted on 714 respondents. Dementia was diagnosed according to the DSM-IV diagnostic criteria, and its subtypes were determined according to the criteria of the NINCDS-ADRDA, the NINDS-AIREN, and the consensus guideline proposed by McKeith et al. [Neurology 1996;47:1113–1124]. Results: The estimated age- and gender-standardized prevalences were 6.3% for dementia (95% CI = 4.5–8.1), 4.8% for Alzheimer’s disease (AD; 95% CI = 3.3–6.4), 1.0% for vascular dementia (VD; 95% CI = 0.3–1.8), and 0.4% for dementia with Lewy bodies (DLB; 95% CI = 0.0–0.9). The prevalence of AD consistently increased with age, whereas that of VD peaked at age 75–79 years and decreased thereafter. Of the dementia patients, 72.0% were in the very mild or mild stages of the disease. Conclusions: The prevalence of dementia in a typical urban area of Korea was estimated to be 6.3%, and AD was the most prevalent subtype. DLB was less prevalent than VD among these community-dwelling Korean elders.

“…Normal mental status was defined as a MMSE score of 25 points or more (maximum score is 30). Scores of 19 or less were interpreted as definite dementia and scores of 20 to 24 as suspected dementia [23,34]. In patients with suspected dementia, a diagnosis of dementia was made with consideration of the age, gender, and education level of the patient [23,34].…”

In patients with suspected dementia, a diagnosis of dementia was made with consideration of the age, gender, and education level of the patient [23,34]. CAM scores are determined using a diagnostic algorithm consisting of four features: (1) acute and fluctuating changes in mental status, (2) inattention, (3) disorganized or incoherent thinking, and (4) an altered level of consciousness.…”

Background Delirium in elderly patients after hip fracture surgery is believed to be a transient event, although it frequently lasts for more than 4 weeks. Questions/purposes We determined the incidence, risk factors, morbidity, and mortality of prolonged delirium in elderly patients after hip fracture surgery. Patients and Methods We evaluated 232 elderly patients (older than 65 years) (232 hips) who underwent hip fracture surgery for the development and duration of delirium and categorized them into three groups; nondelirium group, transient (B 4 weeks) delirium group, and prolonged ([ 4 weeks) delirium group. Patients underwent a global geriatric evaluation, which included postoperative complications, mortality, and functional and mental status evaluations. The three groups were compared with respect to these variables. Results Seventy patients (30.2%) had delirium develop, and among these, 14 (20%) had prolonged delirium with a total incidence of 6%. Multivariate analysis showed preinjury dementia was a risk factor of prolonged delirium. At the final followup, five (62.5%) of the eight patients who were ambulatory outdoors in the prolonged delirium group became housebound, whereas only 18 (16.4%) of the 110 patients who were ambulatory outdoors in the nondelirium group became housebound. Survival at 40 months was 81.0% (95% confidence interval, 72.6%-89.3%) in the nondelirium group and 63.6% (95% confidence interval, 35.2%-92.

SUMMARYBackground Cognitive impairment and depressive symptoms impose a heavy burden on the care of the elderly in Japan and Korea, two of the fastest aging nations in Asia. The purpose of this study was to examine and compare factors associated with cognitive impairment and depressive symptoms among older persons in the two countries. Methods In 2002, representative samples of community-dwelling people aged 65 and older were selected among residents in Anyang, Korea and Yoita, Japan. Mini-Mental State Examination and Geriatric Depression Scale were used to assess the elderly's mental status. Sociodemographics, physical function, chronic conditions, social support, and health behaviors were examined to identify significant associations. Results The prevalence of cognitive impairment in older adults was 17.0% in Anyang and 14.6% in Yoita. The rates for depressive symptoms were 15.2% and 19.8%, respectively. Overall, functional capacity was the universal factor significantly associated with mental conditions. Self-rated health and social support were also found to be independently associated with depressive symptoms in the study subjects. Differences in the patterns of association by community, however, were notable for other characteristics. For example, in factors associated with cognitive impairment, sociodemographic factors such as age, gender, and education were significant among Koreans, whereas socio-behavioral factors such as obesity, social support and hospitalization experience were found to be significant for older Japanese residents. Conclusions Similarities in the patterns of association indicate the need for joint explorations into the role these factors play in affecting the mental health of older persons. Socioeconomic and regional differentials, however, may account for the disparity in the associations observed, suggesting the importance of developing mental health programs sensitive to the older individual's culture.
