An eye-tracking test has been developed for Alzheimer's disease via webcam and may soon be available.

California-based digital health company Neurotrack says its new Imprint webcam-based test is aimed to help those with diseases like Alzheimer’s before behavioral symptoms show up — and it only takes five minutes, MedCity News reports.

The test, which uses eye-tracking technology to detect brain impairments, will be available to be administered by select physicians this year.

Neurotrack co-founder and CEO Elli Kaplan explained that we are all born with a preference for novelty for survival reasons — to seek out new things in our environment, whether consciously or subconsciously.

Neurotrack uses this natural preference to track recognition memory. With the test, users will see pairs of carefully developed images, some identical to each other, some clearly not. The eye-tracking technology monitors how preference for novelty recognition occurs visually, essentially identifying what stands out as interesting and what doesn’t and how that differs for individuals.

Neurotrack’s technology has been used in Alzheimer’s studies and pharmaceutical trials at various institutes, including Brown University, Harvard University, Emory University’s Alzheimer’s Disease Research Center, Stanford University, Weill Cornell Medical Center and NYU Langone Medical Center.
