Toxins - Heavy Metals and Volatile Solvents / Compounds (VOC's) - Detox/Test Before Neurofeedback
I have seen an enourmous rise in heavy metal and VOC toxicity in my client base. I live in Colorado and do neurofeedback training with clients. A vast majority of those really stuck have one or both of these issues prevalent. Colorado has lots of mining and Oil & Gas drilling - so this may be a bit of an oddity, but I would strongly advise anybody to get tested for these things prior to doing brain training.
After the toxicity is removed, the brain is able to hold new states so much easier.
