Neurotrack – Identifying Alzheimer’s Disease 3-4 Years Early

Alzheimer’s is a debilitating neurological disease that continues to elude scientists, researchers, and physicians in terms of the cause, how to detect and diagnose it, and how to treat it.  Elli Kaplan, whose grandparents suffered from Alzheimer’s, founded Neurotrack, an early diagnostic test for Alzheimer’s that can detect symptoms 3-4 years before they appear.

Neurotrack functions as a computer-based memory test that looks at impairments in the hippocampus of the brain, which is the first structure that is impacted by Alzheimer’s disease.  It works as follows: Patients sit in front of a computer screen with an eye-tracking device and view a series of images, some novel and some not novel. Based on how much time a patient spends looking at the novel image versus the image that hasn’t changed, Neurotrack can give you a prognosis.

According to Kaplan, “It is a seemingly simple test that brings together two very complex things: First, a human being’s innate preference for novelty; and second, the discovery, made by Dr. Stuart Zola, that by tracking the way an individual moves their eyes, particularly when viewing objects or images, one is able to diagnose impairments that exist in the brain that migh
