Eye Tracking Predicts Dementia Onset Up To 12 Years In Advance

Scientists have discovered a way to potentially spot dementia years before memory problems begin.

By observing how quickly people's eyes react to a simple visual test, researchers can see if someone might develop dementia later on.

The study found that people who would later get dementia responded slower in a test where they had to spot a triangle made of moving dots.

This is because Alzheimer's affects vision-related areas of the brain before it affects memory.

Though promising, the technology is still in its early stages and needs to become more accessible and affordable.
