My daughter dictated the following replies:

"Thank you both for your replies.

Mark, thank you for the informative response, as always. I could definitely be putting too much emphasis on glutamate because it is one of the few chemical responses I know of that is a feature of concussion.

I am on an antidepressant for my PTSD, and I will be seeing a new psychiatrist this week, so I will ask her whether there is anything else I should be doing to treat it. My sleep is a struggle. I did a sleep study a few months ago, and found that I had chronic slow wave sleep deprivation. As yet, I have found nothing that has worked for that, but I will be asking the psychiatrist about that as well.

There is an Amen Clinic near me. My mother just submitted an online information form, so I will hopefully hear from them soon. Thank you for that suggestion. I will also ask my psychiatrist about Zyprexa (Xyprexa) and see if she thinks it might help me. I also wanted to give a belated thanks for your tip about the threads on neuro endocrine dysfunction. As luck would have it, I am reasonably near Esther's doctor, so we have contacted his office and hope to hear back."

Next, to Joe:

"Joe, it sounds like we may be going through something similar. Did your concussion threshold ever return to normal? Also, where is your doctor located, as I am in southern California? I am greatly reassured about what you said about brain damage. I am scheduled to see a neurologist who is a headache specialist in August. Just out of curiosity, which medication ended up working for you? I wish you all the best with your continued recovery, and thank you for your response."
