The Trail Making Test (TMT) is a widely used neuropsychological test that assesses visual-conceptual and visual-motor tracking. This study provides normative values for TMT scores from 287 normal adult Italian subjects, stratified by gender, education, and age (20-79 years). The test consists of two parts: Part A involves connecting consecutively numbered circles, while Part B requires connecting numbered and lettered circles in an alternating sequence. The difference between Part B and Part A reflects cognitive activity and shifting ability. The study found that test scores were influenced by age, education, and general intelligence, with females scoring longer in Part A. Test-retest reliability was high for all scores. The results are useful for standardizing TMT scores and assessing cognitive function in clinical settings.The Trail Making Test (TMT) is a widely used neuropsychological test that assesses visual-conceptual and visual-motor tracking.
