Good ideas here...
We've tried neurofeedback. The only downside is that you have to practice it on your own. Eg, I did it for headaches, and when I was in a tense situation, I'd remember the computer screen with-the little seagulls on it and get my mind in a relaxed state. Eventually, I didn't have to remember the seagulls on the screen... I could just recall the feeling. But it took a lot of practice. difficult child used it for attention, and never really practiced it outside of the dr's ofc. It was just a game to him, left behind the min. the door was closed. So it's hard to know how much he permanently retained and if any new neuropathways were really kept. You can create new pathways but they have to be used.
FWIW.
