The Food and Drug Administration announced on Monday that it had approved the first brain wave test to help diagnose attention deficit hyperactivity disorder in children.
The test uses an electroencephalogram, or EEG, with sensors attached to a child’s head and hooked by wires to a computer to measure brain waves. It traces different types of electrical impulses given off by nerve cells in the brain and records how many times those impulses are given off each second.
William E. Pelham, the director of the Center for Children and Families at Florida International University, which conducts research on the disorder and treats children who have it, was skeptical about the test.
