NEW YORK - Doctors have discovered a new technique that could treat attention-deficit/hyperactivity disorder and anxiety without drugs.

Pediatrician Naomi Steiner uses attention training called neurofeedback to help children focus.

Steiner explains that when electrodes in the helmet sense concentrating brainwaves, the computer rewards the child by moving a dolphin to the bottom of the screen. 

That positive feedback, she says, trains the brain to focus on something that's not easy for everyone.

In a study published in the Journal of Pediatrics, Steiner showed neurofeedback helps children with ADHD increase attention, decrease activity level, decrease impulsivity and increase executive function.
