EEG Biofeedback, Neurofeedback

[homeschool]

Hello. I wanted to see if anyone has used EEG Biofeedback, Neurofeedback to treat ADHD symptoms . My son is five years old and will be starting kinder in the fall . He has high functioning autism and ADHD as well. I visited The Center for the Brain in Jupiter Florida and have been reading about neurofeedback. please if any one has personally used or used this treatment for their child please let me know of your expirience. I like to know how effective it was. Have the effects maintained or did you have to go back for more sessions. How many sessions total and why did the treatments stop. I live in Palm Beach County as far as i see their are only three places to get this treatment in this county . Two in Boca and one in Jupiter. I thank you for any comments . My hope of courses to not have to put my son on medication or at least be able to hold off till his 8 or 9 to start the med or even to be able to reduce the miligrams. Thank you for your attention
