@elizabeth7 That is a first step, and hopefully will include a full analysis of your symptoms. I hope you live near UCLA or another trauma center. Getting on clinical trials can be madening; I've been trying for 3 mo so far, but do have more test results and an expert on my cancer. Having experts that focus on your complex issues is good (but still madening). Searching on "clinical trial links for traumatic brain injury" may give you additional resources. We are jigsaw puzzles with a lot of missing pieces.
