Visual Test with Flickering Lights May Be Easier Than an MRI to Check Cognitive Function

Until recently, detecting dementia and other cognitive issues required lengthy tests, such as an MRI.

But researchers at the University of Georgia have discovered that a simple technique that measures visual processing speed can more easily provide information about executive cognitive abilities.

Executive cognitive abilities include shifting attention between different tasks, planning, organizing and problem solving.

Performing the test is quick and easy. You simply look into a device inside of which two wavelengths of light flash at increasingly fast speeds. Eventually, you stop recognizing the flash and start to see a circle instead. This is the point at which "critical flicker fusion" (CFF) occurs.
