Eye-scanning app can screen for Alzheimer’s, ADHD

Researchers at the University of California San Diego say they have developed a smartphone app that can check a user’s neurological conditions by scanning their eyes.

The researchers outlined their findings in a paper published on Friday and will be presented at the ACM Computer Human Interactions Conference on Human Factors in Computing later in the week. this. They say the app could allow people to self-assess for Alzheimer’s, ADHD, schizophrenia, Parkinson’s disease and more.

Analyzing how a person’s pupils dilate can provide early clues when neurological conditions are detected. Students tend to relax when one has to perform a challenging cognitive task. Previous studies have found that people with mild cognitive impairment tend to have more dilated pupils than people without any cognitive problems.

“While there is still a lot of work to be done, I am excited about the potential for using this technology to move neuroimaging out of the clinical laboratory setting and into the clinical laboratory setting,” said first author Colin Barry. family,” first author Colin Barry said in a public Friday newsletter. “We hope that this will open the door to new discoveries about using smartphones to detect and monitor potential health problems earlier.”

This app takes advantage of the two front-facing cameras found on most modern smartphones. The phone’s selfie camera is used to record the distance between the phone and the user. The app also uses the phone’s infrared camera, which is equipped on a phone that supports facial recognition technology like Apple’s Face ID, to distinguish the pupil from the iris.

Typically, measuring pupillary response requires specialized and expensive medical equipment. However, the researchers say the smartphone app could be a low-cost and scalable alternative with high accuracy to help more people get screened sooner.

“A scalable smartphone assessment tool that can be used for large-scale community screening could facilitate the development of student response tests in the form of low-cost and less invasive test to aid in the detection and understanding of diseases like Alzheimer’s disease, which could potentially have a large public following, study co-author Eric Granholm said in a news release.
