Hits to the head causing problems in the bloodstream.

scientest have found that when athletes get hit in the head it can cause the semi-permeable membrane between the brain and the bloodstream to open up and let some of the protiens into the bloodstream. your body treats this like an enemy and sends antibodys to distroy them. when this happens some of the antibodys go back through the membrane and attack the healthy brain cells causing brain damage.

    This is an interesting phenomenon. The different cells in the human body work together so well that it is surprising to see that antibodies would treat cells of the same body as foreign threats, a reaction similar to the rejection of a transplanted organ.

    I didn't that the brain proteins can cause antibodies to behave this way. I would think that antibodies would be able to recognize all the cells of the body as domestic. Here is an article that talks about Autoimmune Brain Disease, the name of the condition you speak of. http://www.tchain.com/otoneurology/disorders/autoimmune/aibd.html

    I found this extremely interesting because I have suffered a concussion and I had no idea this was going on. I find it so intriguing how the body wouldn't recognize its own brain cells and would go on to attacking them. I found an interesting article that said it doesn't take a major brain trauma to cause this phenomenon to occur, but any hit to the head. The force of the impact, however, does greatly affect the amount of the "foreign" proteins in the bloodstreams.

    I am very interested in brain injuries, so I found an article that talks about other long term effects http://www.brainandspinalcord.org/recovery-traumatic-brain-injury/traumatic-brain-injury-effects/index.html Common symptoms are vomiting, dizziness, speech and language problems, and amnesia. Many head injury long term effects are on the senses, including problems with vision, hearing, smell, taste, and touch. The brain may also have problems telling left from right, doing math, drawing objects, recognizing objects, and following directions. Another common long term effect are seizures.

    This is a very interesting article because of how big of an issue concussions have become especially in sports. I have always heard stories about athletes who suffer multiple concussions and have lasting effects with memory and motor skills as they get older and this article explains some of the science behind why these problems occur.
