Abstract
Although the Trail Making Test (TMT) Part A, B, Wisconsin Card Sorting Test-KFS version (WCST-KFS) and Miyake's Verbal Paired-Associate Learning Test (MVPLT) are simple tools to evaluate cognitive dysfunction in patients with traumatic brain injury, there is very little normative data for young persons available in Japan. Therefore, we evaluated 124 healthy persons who were from 15 to 30 years old with the three assessment tools. Median numbers of TMT Part A and Part B were 23.8 seconds and 49.0 seconds, respectively. Median numbers of achieved categories, perseverative errors of the Nelson type, and difficulties of maintaining set in the WCST-KFS were 5, 2 and 0, respectively. Median numbers of correct answers for related and unrelated pairs of MVPLT were 10 and 9 at the third trial, respectively. TMT Part B and perseverative errors of the Nelson type had a negative and weak correlation with age. And related pairs of MVPLT at the first trial had a positive and weak correlation with age. The normative values obtained in this study would be a useful standard for clinical assessments and acknowledgment of disabilities.
