Post Traumatic Stress Disorder (PTSD)
Post Traumatic Stress Disorder is an anxiety disorder that results from being exposed to a traumatic event. When the body feels that it is in danger it reacts with a “flight or fight” response that is meant to protect a person from harm. When the body is faced with terror, functions such as memory, emotion, and thinking are shut off because they are less important at the moment. This allows the body to focus solely on increasing the heart rate, moving more blood to the muscles in order to run and adds stress hormones to help fight off infection and bleeding in case of a wound (National Alliance on Mental Health website, 2014). As a result, the traumatic experiences are unprocessed at the time it is happening because the body is so focused on immediate physical safety. Therefore, these unprocessed memories can occur at any given time, without warning leaving a person with PTSD feeling stressed or frightened even when they are no longer in danger.
Currently scientists are studying ways that may make one more likely to be at risk for PTSD. Scientists believe that genes may play a role in creating fear memories; they have pinpointed genes that make stathmin (a protein needed to form fear memories) and gastrin-releasing peptide (GRP) (a signaling chemical in the brain released during emotional events), testing both on mice (National Institute of Mental Health, 2013). In a study on stathmin, “mice that did not make stathmin were less likely than normal mice to “freeze”, a natural, protective response to danger, after being exposed to a fearful experience. They also showed less innate fear by exploring open spaces more willingly than normal mice” (National Institute of Mental Health, 2013, p...

It seemed that the troops were responding fairly well in stage two to the interventions put in place until that stage ended in 1968. From 1968-1975 the psychiatric disposition of the troops went downhill, it was believed that psychiatric disorders were being masked by heavy amounts of substance abuse. It is believed that the high rate of PTSD in Vietnam war veterans is attributed to the nature of the conflict itself – “non-existent battle lines, young age of soldiers, and public disgrace upon returning to America” (Kabatchnick, 2009, p. 274). PTSD was then officially recognized as a mental disorder in 1979 after the amount of battle trauma experienced by Vietnam Veterans (Kabatchnick, 2009).
