Has anybody used this type of device. I have twins and one of them is struggling through the executive function issues. The other has no issues, other than a typical 10 year old would suffer from. I have had the luck of a benchmark to judge the success of medication and other therapies against. The twin with ADHD is not hyper anymore but has a hard time getting the ideas from his head to the paper. We have gone through all types of therapies with psychologists and have found them unproductive for the child and way too expensive for the results. Anyway I have read a lot about this therapy and found that I could buy the machine and use it at home with less counselling sessions to help keep the cost down. Let me know if you have used it and has it helped?
