TMT-B and KWIS subtests were administered. The result of this study was difference of performance time was significantly founded among group. The education was not correlated with performance time, but age and intelligence was significant correlated with performance time. In other words, the study show that severity of impairment, demographic data of age and intelligence correlated with TMT-B performance. This study suggested that the Trail Making Test was useful for assessment brain damage level.
