“A properly functioning brain is entirely dependent on balanced and healthy function of the immune, digestive, and endocrine systems.” So consider diagnosing PTSD as a “neuro-endocrine-immune problem” and treating with Frequency Specific Microcurrent (FSM) “to address over activity and inflammation in specific parts of the brain, raise serotonin levels, quiet central sensitization, quiet inflammation generally, and specifically increases vagal tone.” from a Townsend Letter research article, “Mental Health, the Brain, and PTSD” by Carolyn McMakin, MA, DC.
