Laupala,

I have never said you will not recover from your concussion symptoms, nor did Dr Gronwall's research. What I said is that symptoms may return during times of stress. Her research in to 70's dealt with an 8,000 foot altitude oxygen level. She has done more research since then. I just have not had the funds for her more recent book. I think it is $80.

Her 70's research did not address the other stresses we may face but extensive anecdotal evidence says that many other forms of stress can cause a return of symptoms. Plus, I have read other reports and articles that support this. I do not remember what the studies were like so I have not promoted those studies.

And, my neuro-psychiatrist also told me this. He said that stress causes toxic chemical buildup in the brain that results in a weakened condition with a return of symptoms. These symptoms may be concussion symptoms for those with a concussion history and/or them may be symptoms of depression. He is the one that got me started on the vitamins and supplements regimen.

Regardless, you still have healing to do. You may return to a symptom free condition and only need to be aware of stress issues.

I don't see a reason to get worried or frustrated. As I have said many times, anxiety/stress is one of the biggest things that delays recovery. Taking a positive approach to recovery by reducing stress as much as possible is the best way forward in my opinion.

There is no reason to expect to not recover from the struggles you are having now. Only a small percentage have prolonged struggles.
