Klaus,

Your sensitivity to light jolting is a result of your autonomic nervous system going haywire. Your brain is constructed in a way that you have your limbic brain (aka reptilian brain or primitive brain) that is there to regulate all of the things our bodies do that we don't think about like digesting food, your heart beating, etc. It's also there to protect us from danger i.e. it controls your "fight or flight" response. The other part of your brain is your outer cortex which is involved in higher functioning like sight, reasoning, thinking, talking, listening, etc. A region in this part of your brain is called the frontal cortex and this is responsible for very high levels of function. In other words, this is the part of our brain that makes us human. This part of your brain is responsible for inhibiting your limbic brain; it acts as sort of a control mechanism and filters out the signal from your limbic brain. When you have a brain injury, in some people, your frontal cortex can no longer handle it's job of filtering the limbic brain and as a result, your limbic brain is allowed to go haywire.

So, when you get a slight jolt or something, your limbic brain automatically sends off signals that you are in very grave danger and this starts a cascade in your brain that will cause you symptoms. It is impossible for you to do any damage to your brain physically by these slight jolts but that doesn't mean that you don't do damage to your brain psychologically. When these signals are sent out, they are sent out via neurotransmitters and what could be happening (of course no one has proved this) is that your brain changes and becomes more sensitive to the neurotransmitters that cause the flight or fight response and hence, you become more sensitive to any bumps or jolts.

Now, I suffered from this as well for about 4 years and I fortunately was able to overcome it. I fixed it in a couple of ways. First, I discovered that I was suffering from hypothyroidism and adrenal fatigue, both that are common in people with head injuries. Your adrenal system actually plays a huge role in the scenario I mentioned above. So, I got both of those systems treated and this helped immensely. Second, I did some neurofeeback directly onto my frontal cortex and strengthened that part of my brain to be able to handle any stress my body may incur. Third, I did some HBOT as well and this also helped with the sensitivity. Fourth, I also did some balance training to try and get my vestibular system back in order. Finally, I went to an upper cervical chiropractic specialist who put my neck back in order so that my neck could go back to being the shock absorber it's supposed to be.

I am now about 80-90% recovered and although big bumps and jostles still bother me a little bit, I am able to handle the small to medium bumps and jostles that I wasn't able to handle before.

Hope this helps.
