Eye Tracker Exam Shown to Detect Alzheimer’s in Early Stages of
Disease According to an article from online technology magazine,
Gizmag, researchers believe they have discovered a way to detect
the early stages of Alzheimer’s through an eye tracking exam.
The results of the exam are believed to give insight into the
brain’s ability to store and remember the spatial positioning of
objects in an environment. Researchers performed the eye
tracking test on 79 people: 19 Alzheimer’s patients, 25
Parkinson’s patients, 17 elderly patients, and 18 healthy young
people. Participants were asked to follow the movement of a
light on a monitor and occasionally look away. The results of an
eye tracker exam are dependent upon the data picked up by the
retina recorder, which measures a patient’s gaze position as
well as how quickly the focus is corrected to the original
position. Dr. Trevor Crawford, of the department of Psychology
and the Centre for Aging Research at Lancaster University, said,
“This study takes this work f
