Trail Making Test
The Trail Making Test (TMT) is a simple, brief neuropsychological test developed by Reitan in 1958 that measures visuomotor processing speed, attention, and executive function. The TMT comprises two forms: Part A, which assesses basic processing speed and visual scanning, and Part B, which assesses executive function, task-switching, and cognitive flexibility. Despite its simplicity, the TMT is highly sensitive to cognitive impairment across a wide range of neurological and psychiatric conditions and remains one of the most widely used screening tests in neuropsychology.
