Bottom Line: Analysis of variance was used to test the subject group effects on the scores in the above writing tasks.For the picture story writing task, the mild AD and aMCI groups performed worse than the controls, but the difference between the AD and the aMCI groups was not significant.Our study suggests that narrative writing, which demands complex integration of multiple cognitive functions, can be used to detect the subtle writing deficits in aMCI patients.

ABSTRACT

Background/aims: We investigated writing abilities in patients with the amnestic type of mild cognitive impairment (aMCI) and mild Alzheimer's disease (AD). To examine the earliest changes in writing function, we used writing tests for both words and sentences with different types of Japanese characters (Hiragana, Katakana, and Kanji).

Methods: A total of 25 aMCI patients, 38 AD patients, and 22 healthy controls performed writing to dictation for Kana and Kanji words, copied Kanji words, and wrote in response to a picture story task. Analysis of variance was used to test the subject group effects on the scores in the above writing tasks.

Results: For the written Kanji words, the mild AD group performed worse than the aMCI group and the controls, but there was no difference between the aMCI group and the controls. For the picture story writing task, the mild AD and aMCI groups performed worse than the controls, but the difference between the AD and the aMCI groups was not significant.

Conclusions: The mild AD group showed defects in writing Kanji characters, and the aMCI group showed impairments in narrative writing. Our study suggests that narrative writing, which demands complex integration of multiple cognitive functions, can be used to detect the subtle writing deficits in aMCI patients.

The picture story (4-frame cartoon) ‘a chestnut tree and a child’, from the SLTA-ST, was used in the sentence writing task.

Figure 2: The picture story (4-frame cartoon) ‘a chestnut tree and a child’, from the SLTA-ST, was used in the sentence writing task.

Mentions: To assess sentence writing abilities, the subjects were asked to give a written description of the picture story (4-frame cartoon) from the Supplementary Test of the Standard Language Test of Aphasia (SLTA-ST). We used the picture of ‘a chestnut tree and a child’ (fig. 2). That story is more difficult than the SLTA version and represents the middle level of the picture stories in the SLTA-ST. We used this task to evaluate how the subjects understood the stream of a story and to prompt them to increase the number of sentences they wrote.
