Research on twins and families indicate the possibility of a genetic diathesis in PTSD. Moreover, the trauma may activate noradrenergic systems, increasing the level norepineflin so as to make the person concerned more easily startled and express emotions faster than normal. Consistent with this view is the finding that norepineflin level higher in patients with PTSD than in the control group. In addition, stimulates the noradrenergic system causes panic attacks at 70% and 40% of flashbacks in PTSD; none of the control group who experienced that sort of thing. Lastly, there is evidence of increased sensitivity of noradrenergic receptors in patients with PTSD. Apart from the existing numbers, that PTSD actually needs healing for what happened to them, one of them is the el camino Sagrado holistic healing center.
Learning theorists assume that PTSD occurs as classical conditioning to fear. A woman who had been raped, for example, may feel afraid to walk in a particular environment (CS) due raped there (UCS). Based fear classically conditioned avoidance occurs, which negatively boosted by a reduction in the fear generated by the non-existence in the CS. PTSD is a prime example in the theory of two factors concerning avoidance learning proposed by Mowrer years. There is a collection of evidence that supports this view and is associated with cognitive-behavioral theories that emphasize the loss of control and predictability perceived people who suffer from PTSD.
A psychodynamic theory proposed by Horowitz stated that the memory of a traumatic event appears constantly in one’s mind and consciously so painful that they do suppressions (through distraction, for example) or repression. The person concerned is believed to be having some sort of internal struggle to integrate the trauma into his confidence about himself and the world to be able to accept it sanely. PTSD can occur at all ages but children and old age (> 60 years) is an age group more prone to PTSD. Children have special needs and vulnerabilities when compared with adults, trauma because it is still a dependency on others, physical and intellectual capacities that are growing, and lack of life experience in solving various problems that can affect the development of the child’s personality.
