Demographic influences on baseline and derived scores from the trail making test in healthy older Australian adults

Abstract

Normative data from 363 community-dwelling older adults (60-89 years) is presented in relation to performance on the Trail Making Test. Age and years of education were identified as significantly impacting on performance. Therefore, data are presented for four separate age groups (60-69; 70-74; 75-79; 80-89) and two different lengths of education. In addition to data for Trails A and B, information is provided for the difference and ratio scores, which are increasingly used by clinicians to interpret executive function.
