| Research Abstract |
Mild AD had an impairment in Kanji writing with a large amount of non-response errors, which can be interpreted as deficits of retrieving and retaining morphological Kanji-character images. The non-response errors were correlated with hypoperfusion in the inferior parietal lobule, the posterior middle and inferior temporal gyri, and the posterior middle frontal gyrus in the left hemisphere. Damages to these regions may affect a series of the process from retrieving Kanji representation to activating kinesthetic memory for writing, causing dysfunction of neural network for processing Kanji-character form.
