The Food and Drug Administration approved the first brain scan that can help diagnose attention deficit hyperactivity disorder in children, The Associated Press reported.

The device measures the frequency of two standard brain waves known as theta and beta waves. Children with ADHD have a higher ratio of these waves than children who don’t have the disorder.
