알츠하이머병 환자에서의 삶의 질 평가

초록

Backgrounds: Evaluating quality of life (QoL) in people with dementia has become increasingly valued, especially in assessing the effectiveness of interventions or making treatment decisions. However, limited information exists regarding dementia patients’ QoL in Korea. The aim of our investigation was to determine if the severity of dementia could affect the QoL of patients with dementia and the relationship between QoL score and the scores of other cognitive domains, especially, the attention. Methods: Two hundred and sixty eight subjects with varying degree of cognitive dysfunction underwent assessment of Korean-Mini Mental Status Examination (K-MMSE), digit span, trail making test (TMT), Korean-Instrumental Activity Daily Living (K-IADL), Geriatric Depression Scale (GDS), Clinical Dementia Rating Scale (CDR), attention and their QoL using standardized neuropsychological tests and questionnaires. We administered the QoL in Alzheimer’s disease (QoL-AD) scale and attention questionnaire to the subjects. Results: QoL-AD score had a positive correlation with K-MMSE score (r=0.38, p<0.0001) while it showed a negative correlation with GDS (r=-0.62 p<0.0001). QoL-AD score also showed a significant correlation with attention status of the patients with dementia (r=0.48, p<0.0001). QoL-AD score for patient appeared to be affected by educational factors. Conclusions: QoL-AD may be used as an effective tool to assess QoL as well as cognitive functions of patients with varying degree of dementia.
