CNS; Response on Trauma

Sažetak
In every threatening uncontrolled experience, CNS always responds in the same way: with FIGHTING, ESCAPING, NUMBING. If the stress lasts very long time or repeats constantly the organim can not be in a contition of alarm simpatic function so it comes to exhaustion and gradually development of the symptoms. Immediately after the experienced stress or even during the traumatic event, an organism can react pathologically. So, there is no fight or escape reaction, but numbing. Emotional reactions does not exist, the person is behaving like nothing happened. Reexperiencing activates the limbic system. During our development we create the feeling of affection, loyalty and depending on experiencing these feelings, we can build relations with other people. Trauma destroys the basic trust in people. Defending against reexperiencing of traumatic events is avoiding recalling the traumatic events. The organism isself wishces to reduce the pain and produces the opioids which lead to reducing the pain or analgesia. If the traumatic event comes back, the organism is defending with increasing of opioids. During the time, opioid analgesia develops as a response on continuating stressors or the addiction to traumatic event develops in order to increase the level of opioids and by doing this well being state could be artificial achieved. In cases where opioid levels do not increase a contitional reaction on external stimulus occurs. There is no more possibility of choosing and categorization of the external infomation so CNS responds equally on each stimulus. PTSD patients produce opioids equivalently with 8 mg of morphine. In such a way it occurs the change of responding on all pain stimulus. The organism develops the capacity for modeling psychological excitation. There is a cognitive preparation which is related to the level of physiological disorganization and it determines the capacity for mentl processing of potential traumatic events. Whwn there are extreme stressors,memorizing and processing the information on verbal and symbolic level is damaged so trauma is chaning it from conscious to somatic difficulties. Concerning the hypocampus which is trying to remain the usual balance of rewards and punishments, traumatic event disturbs this function and leads to a constant excitation of organism. Increased excitation of the organism activates serotoninergic and holinergic mechanisms. Since the organism is not able to deal with permanent excitation, each remainder of trauma leads toward the loss of the control and aggressive behavior. Long-term excitation leads toward decreasing of the serotoninergic activity, which inhibits control of the system of behavior. Cateholamin answer is changed as well and leads toward sudden aggresive reactions, lack of associations, rigidity in the process of thinking, gastric difficulties, permanent stimulus to urinate, mutism and the need to torture others.
