Pupil-tracking smartphone app looks to catch early-stage Alzheimer’s
A prototype smartphone app has been developed to screen for the very earliest stages of Alzheimer’s disease. The app tracks minute changes in a person’s pupil size, which previous research has shown can indicate pre-clinical neurological disease.In 2019 a team of researchers from UC San Diego demonstrated how pupil response tests could identify subjects with a high genetic risk of developing Alzheimer’s disease. The test involves closely tracking pupil size changes while a person is completing a cognitively taxing…
