A recent discovery could revive early detection of Alzheimer’s disease. Researchers are currently testing simple ear microphones that can detect signs of the disease years before it is diagnosed.
Scientists at the École de Technologie Supérieure and Dartmouth University have developed and tested technology that listens to the subtle sounds produced by eye movements – sounds that could reveal early signs of cognitive decline, according to Science Alert.
“Eye movements are interesting because they are some of the fastest and most precise movements in the human body, so they rely on both fine motor skills and cognitive activity,” explained researcher Arian Shamei.
But scientists are paying attention to involuntary eye movements called saccades – rapid movements of the eyes that come out as we explore our surroundings. In people with Alzheimer’s, these movements become slower and more precise, which can be an early warning sign of the disease.
Although these changes have traditionally required expensive eye examination equipment to detect, the research team believes they have found a simpler and cheaper solution.
It’s about a hearing aid. “It’s a headset with built-in microphones, which captures physiological signals from the body. Our goal is to develop health monitoring algorithms for hearing aids that are capable of continuous, long-term monitoring and early disease detection,” explained Miriam Boutros, who was involved in the study.
The science behind this procedure is surprisingly simple. When the eyes move, small vibrations are created in the eardrums, which are detected by sensitive microphones.
In the future, this technology could be incorporated into everyday devices such as wireless headphones, providing continuous, non-invasive monitoring of early signs of neurological conditions.
