Pain-induced coma resulting from alteration of RAS. Real Science or Myth?
2007-02-05 12:31:47
Hi:
I posted this message before but didn't get any answers. I apologize profusely to those who are annoyed by the repeated message. The following martial arts site discusses certain techniques to incapacitate opponents. The one I quoted talk about pain causing loss of consciousness by disrupting the reticular formation. Is this true science or just some age old myth? quote from http://72.14.253.104/search? qĘche:ziuTpWWP9_oJ:www.internetarmory.com/self_defense.htm+%22neural +shock%22&hl=en&gl=us&ct=clnk&cd=3 : "It is speculated that various organs of the body can send pain impulses to the brain stem indicating a severe or overwhelming bodily injury. The reticular activating system responds by producing a functional "shut down", which results in loss of consciousness within a second or two." If this is real science, then what is mechanism in which the so-called "shut down" occurs? Any understanding, cooperation, and assistance is greatly appreciated. Thanks, Radium

Have you tried Googling "reticular activating system?" -- Notan

> Have you tried Googling "reticular activating system?" Um, yes. Still haven't found the direct mechanism how in which a blow to a pain-sensitive area would cause the RAS to shut-down consciousness. What is this mechanism??? And no, I am not talking about the autonomic nervous system's response to pain. I am talking about a direct link between excruciating pain and a decrease in consciousness regardless of how -- or whether at all -- the autonomic nervous system is affected. According to the information on that martial arts website, severe pain can directly cause coma by shutting off the RAS. This means that even if the link between pain and autonomic functions were broken, excruciating pain would still cause the victim to lose consciousness -- without syncope or any decrease perfusion of blood to the brain. IOW, there is a direct, purely-neurological, non-cardiac, non- circulatory, non-vascular, non-respiratory, non-autonomic, non- endocrine, non-hormonal mechanism in which extreme agony rapidly leads to coma. Just what is this mysterious mechanism?? Seriously?!

You really think there are scientist on this board? I once banged my knee into a steel gate on accident. The intense pains, caused me to loose conciousness for a few minutes. Woke up on the ground.

What you experienced was a vasovagal syncope [nothing at all to do with RAS]. Vasovagal syncope is a parasympathetic over-reaction to extreme stress. Such stressors include -- but are not limited to -- extreme emotions, foul odors, or intense pain. In a vasovagal syncope, the following occurs for a very short time: 1. Force of the heart muscles' contractions decrease significantly 2. Heart rate decreases dramatically. 3. Blood vessels around the body widen The above 3 cause blood pressure to drop briefly but intensely. As a result, the brain does not get the blood it needs and you transiently lose consciousness. Once again, though, this has absolutely nothing to do with the claim on that martial-arts website about intense pain directly causing the RAS to shut consciousness off.
