A 3-minute brainwave test could spot Alzheimer’s years before symptoms

Scientists at the University of Bath have developed a simple three-minute brainwave test called Fastball EEG that can detect memory problems years before Alzheimer’s is typically diagnosed. Unlike traditional memory tests, it passively records brain responses to images and has now been proven effective in people’s homes. With breakthrough Alzheimer’s drugs working best in early stages, this low-cost, accessible tool could transform early detection and treatment.
