The Yonkers study showed both that Neurofeedback worked for a large number of people or a long period of time or a large number of kids at least! It cannot be limited to one or two anecdotal papers. A study at the Enrico Fermi School in New York study children with problems related to ADD, learning disabilities, acting out behaviors, and depression.
Neurofeedback was brought to a school of 900 children. 300 hundred children were treated at no charge with neurofeedback over the course of the study of 5 years. This included 2 other public schools along the way. Children had some changes or tremendous gains resulting in better overall focus and better self-esteem. Other outcomes included less suspensions, better attendance, and fewer truancy behaviors. There were not any noteable side effects noted in the study and several schools in the U.S. have continued to utilyze neurofeedback with their students.
This study allowed the researchers to track acting out behaviors to pinpoint changes in behaviors. Studies such as these have continued in the field (Robbins, 2000b).
