경도 알츠하이머성 치매환자와 경도 혈관성 치매환자의 쓰기서술 특성

다국어 초록 (Multilingual Abstract)

Purpose: The purpose of this study was to investigate the narrative writing characteristics of mild Alzheimers dementia (AD) patients and mild vascular dementia (VaD) patients. Methods: Participants included 15 mild AD patients, 15 mild VaD patients, and 15 normal elderly (NE). Two writing tasks (single-figure picture task (S-P), continuous picture task (C-P)) were presented to all participants. The study was designed to examine whether there were any differences between each group in semantics, syntax, speed, and other aspects (modification, errors) of narrative writing. Results: First, in semantics, in the S-P task, CIU ratio was high in order of NE, VaD patients, and AD patients and showed significant differences between all three groups. In the C-P task, the CIU ratio of the NE group was significantly higher than VaD patients. Second, in syntax, in both two tasks, there was no significant difference among the three groups. Third, in speed, in the S-P task, the writing time and total time of the patients with VaD was longer than the NE group. In the C-P task, the planning time of VaD patients was longer than the NE group. In both tasks, the number of CIU per minute, the number of words per minute, and the total number of syllables per minute were significantly different between the groups. The NE group was fastest. Fourth, in the other aspects, the most frequent type of error was phonological error-replacement. Conclusions: From these results, the CIU ratio, the writing time, and total time were found to be the main variables. It is meaningful that this study attempted to determine the differences in narrative writing between AD patients and VaD patients.
