Notes: The Japanese version of each test was used. The asterisks against values under the Wechsler memory scale, revised edition (WMS-R) indicate that the scores are lower than those of standardized samples (*: 2SD, **: 3SD). The Miyake paired-associate word learning test is a memory test in which the subject is asked to recall 10 pairs of related and unrelated words (normal range of accuracy, 8–10 for related pairs of words and 5–9 for unrelated pairs of words). The Zung self-rating depressive scale is a measure of depression (normal, <40; borderline, 40–50; depressed, > 50).
