Trails B

The Trails B test consists of a map of numbered bubbles. This test requires the user to connect these bubbles together in number-letter-number-letter ascending order. For example 1 goes to A, A goes to 2, 2 goes to B, and so on. If the bubbles are incorrectly connected, the line will turn blue and the user will have to start at the last correctly connected bubble. The test is complete upon connecting all the bubbles. This test assesses frontal executive function, MCI, and is an early warning sign for Alzheimer’s.
