notcrqazy,

The 30 sec LOC at 10 yo was a very significant impact. Even the 1-2 sec LOC is significant.

LOC elevates any concussion to a serious level. Your comment about any 'significant knocks to the head' is interesting. Your brain does not need a significant knock to the head to be concussed based on your history.

Have you ever had a light bump to the head where you had a metallic taste (like chewing aluminum foil) in your mouth or you say spots for a few seconds?

Studies show the brain can tolerate some severe hits without any immediate concussion symptoms. Impact forces from 60 to 170 G's were recorded. Many were not even obvious when video tape was reviewed. The brain's tolerance is variable from one person to the next. It is known that immediate symptoms or lack thereof do not necessarily predict later symptoms.

For you, the important issue is your current symptoms. Concussion is not treated as a cluster of symptoms. Rather, the individual symptoms are treated. By treated, many times this just means developing acceptance of the symptoms and learning to work around or with the symptoms.

Learning to avoid certain environments is imperative. Learning to minimize all symptoms is valuable because studies show that healing is most likely during symptoms free periods.

You definitely sound like a Multiple Impact Syndrome candidate. You may have reached your limit for recovery due to available reserve brain capacity. Your only opportunity for recovery may be learning to minimize some symptoms and learning to live with the others. Work-arounds and other accommodations can enable you to return to much of your previous life.

At this point, you will need to get to know your 'new' body/brain. Your prior physical capabilities have little bearing on your current condition.

List your most disturbing symptoms so we can offer suggestions for work-arounds and other accommodations.

My best to you.
