Mark it sounds like your experiences have made you a far more compassionate person. I really, really admire your views about your injuries and resulting issues. Reading your posts has helped me to move away from "futurizing" any number of times. *Sigh*, that work is ongoing.
Unfortunately my daughter has had at least three concussions, the third was terrible. And given what she went through after the 10k last spring, I do believe that was yet another concussion for her brain and not a good one.
Her dyslexia predates all the concussions. We ultimately did something called Arrowsmith and it was incredibly helpful. Due to cost and very, very limited availability this amazing program is able to help only a few. They have a website if you are interested.
Good news for your nephew with the Lindamood-Bell program

I've heard good things about it. I hope the doors to his strengths and talents will be opening wide.
My daughter does have an IEP and we are very pleased with how that is being handled this year in her grade nine. The resource teacher is excellent.
Thanks for the encouragement. I too have to remember to slow down, this is a marathon not a sprint, eh?
There is a doctor who specializes in bio-identical hormones and I can just call for an appointment. Her website looks good. I do feel that given the timing of all this it should be checked out.
I'm going to run my big worry by you. Last spring the PCS started with about a week or so of headache and then went into every concussion symptom in the book. I believe that was the lag time between the run and the full symptoms, with the stress at school being the final straw (again timed testing).
Do you think, based on your experiences and research etc. that this could play out like that as well, with mental stress as the trigger? So far she's holding, but we are not to 7 to 10 day point.
