Can We Develop a Brain Test for ADHD?
KEY POINTS: Researchers have examined how electrical activity of the brain relates to attention. The ratio of slow waves to fast waves at the front of the brain, called the Theta Beta Ratio (TBR), is key. TBR has been related to trait levels of attentional control and drive to pursue goals, and to mind wandering. TBR cannot distinguish between people with and without ADHD, but it may help us understand attention better.
