Bio-neuro feedback


My son had been diagnosed with ADHD, and we started bio neurofeedback treatment on him and this has really helped but not the cheapest . Just wondering if any adults here have used this treatment and has there been a difference. I suspect my husband is very ADHD. I will give him 3 items to go and buy from the shops. He will come home with only 2 items, etc. The list goes on , time management, prioritisation etc.
