Real therapies vs grifting

Like most of us I’m trying to everything in my power to give my child a better outcome and more independence as he gets older. It’s well established early intervention like speech/ot/aba is evidenced based but I personally get overwhelmed at times trying to read and learn about what therapies could actually lead to real gains. Like what is “emerging” but not mainstream vs people just looking to make money off desperate parents.

I follow a group called TACA that’s pretty popular but I can’t always tell if someone is falling victim to a grift or if mainstream medicine just hasn’t caught up yet.

Stuff like brain balance, stem cells, red light therapy, special diets, mito cocktails, ect. Even tests like Cunningham panel are always recommended but I go look it up on my own and it’s considered inaccurate by mainstream doctors.

They link a lot of publications but it gets confusing and I feel like the more I read the less I understand if there’s something to it or it’s just money making bs.

I just want to know if anyone else feels this way? Or if anyone has had a lot of success following these treatments and protocols.
