ASKED QUESTIONS:       

Q:  I have heard that many professional athletes have been treated by neurotherapists.  Can neurotherapy improve the performance of activities other than sports?     

A:  “Very decidedly so.  At the very least, neurotherapy (neurofeedback) will increase your IQ.”     Dr. Swingle has a research paper which documents the average IQ goes up 10 to 12 points.
