In today's podcast episode, we'll talk about a pioneering brain wave test that could dramatically increase the early diagnosis of Alzheimer's. This new EEG technique is known as Fast Periodic Visual Stimulation and joining us on today’s episode to better understand it is none other than Dr George Stothart. He is a senior lecturer at the University of Bath and one of the creators of this two-minute test that can measure people's brain waves in response to a series of flashing images.
