A Silicon Valley health start-up, Neurotrack, is developing a computerized visual test that aims to accurately identify people at risk of Alzheimer’s. The test requires no language or motor skills; participants view images on a monitor while a camera tracks their eye movements. According to Scientific American, “The test draws on the research of Neurotrack co-founder Stuart Zola of Emory University who studies learning and memory in monkeys. When presented with two images—one novel, the other familiar—primates will fixate longer on the novel one. If the hippocampus is damaged, as it is in Alzheimer’s, however, the subject spends equal time looking at each image.”
