On September 11th, 2001, the world seemed to stop as the result of the World Trade Center collapsing. This catastrophic event started the on-going war with the International Security Alliance Federation in coalition with Afghanistan against Al-Qaeda. The combat and brutality in Afghanistan have left native Afghans in thrall of Al-Qaeda and other terrorist groups such as the Taliban and Isis. The fighting, bombings, and randomized killing of civilians has rendered the idea to thousands of Afghans to seek refuge in a country that they do not call home. These refugees have experienced traumatic events such as but not limited to losing loved ones, going through human trafficking rings, and seeing explosions and exchanges in military combat.

It is said that many genes have small contributions to the overall symptoms of PTSD. For example, stathmin (STMN1) is a protein with a main function of overseeing the remodeling of a cell's cytoskeleton. Stathmin has also been found to help form responses to fear and anxiety stimuli. (Stathmin, a gene) In addition to stathmin, Gastrin- releasing peptide (GRP) is another gene that has an effect on PTSD. Alterations in GRP have an impact on fear-related responses and can help alleviate them. (Role of) Also, 5-HTTLPR is an additional gene that has correlation with PTSD. 5-HTTLPR can have an effect on the daily stress level on an individual. Changes in these genes can cause a change in severity in patients with PTSD. (Daily …show more content…
There are three main regions of the brain that contribute to PTSD. The amygdala, in particular, has to due with the processing of emotional reactions. (Post-Traumatic Stress Disorder) It has been shown in a study that a smaller amygdala volume has been linked with PTSD. (Duke Institute) Another area that can play a part in PTSD is the prefrontal cortex (PFC). The prefrontal cortex is said to store memories of decimating certain fears. It also has the job of lessening the original response to fears. Irregular function or abnormally small size can help with the chances of PTSD. In the same way, the ventral medial prefrontal cortex helps keep away conditioned fears. Experiencing traumatic events can put a damper on these areas of the brain and can trigger PTSD.

Ptsd: Causes and Symptoms

...07/25/13 Summary for HES 1 Post Traumatic Stress Disorder: Causes and Symptoms Every individual has gone through some sort of danger. Everyone, at some point, has been afraid. Fear triggers many instant changes in the body. These changes help the body prepare itself to defend against danger or to avoid it. This is taught as the “fight or flight” response. It is a healthy reaction meant to protect an individual from harm. But in post traumatic stress disorder, this reaction is changed or damaged. Traumatic events bring out a reaction from an individual that may be different from that of another. Everyone is unique to their own ability to manage fear or stress and to cope with any threats posed by a traumatic event. This is why not everyone who experiences or witnesses a trauma will develop post traumatic stress disorder. It is not known why traumatic events cause PTSD in some individuals and not in others. In a time a traumatic event, the body will release stress hormones and chemicals. Generally, the body will recover after the event, and hormone and chemical levels will return to normal. For some reason the body of an individual with PTSD will continue to release the stress hormones and chemicals. Whether or not an individual will develop PTSD depends on many contributing factors. Some of these factors can be genes, emotions, and family settings, the intensity or duration of the trauma, any injuries or deaths as a result of the traumatic event, the distance from the...

Cause and Effect of Stress in Young Children

...Draft Version Jacqueline C. Winfield Professor Leverett Butts English Composition- ENG 115 Friday, November 22, 2012 Young children are not always the first people we think of when it comes to the stress factor. We tend to believe that they are living in their best years, however with changes in economic situations such as parents not remaining married, being exposed to violence, and even feeling the need to belong a child can become overwhelmed. According to Wikipedia contributors, stress in young children can be beneficial to proper growth and development if it is not persistent (2013). Stress in young children should be monitored by caregivers, teachers, and others to prevent youth from damaging brain developments, which may alter the child’s psychological and social growth. The three different levels of stress in children are: Positive Stress, Tolerable Stress and Toxic Stress. Positive stress encourages competence. Tolerable stress is more problematic but is brief. This may occur when there is a death of a close loved one. Toxic stress are very extreme and may cause developmental damage (Wikipedia, 2013). With the proper support children should be able to overcome many of these circumstances. Changes in young children lives may cause stress. It is a major issue for adolescence that have problems with adjusting to new conditions. From birth a child comes into a world that the things surrounding him or her set the bar for farther expectations. They...

...Diagnosis The patient, Holden Caulfield is experiencing what I presume to be Post Traumatic Stress Disorder, or PTSD. Holden is going through a lot of difficult situations in his life that he got him a little mislead, such as failing almost all his classes, trouble with his roommate, and leaving his school altogether. The situations Holden is being put through aren’t easy for him and cause him a lot of stress that changes the way that he acts, and feels. Caulfield is experiencing flashbacks, poor relationships, self-destructive behavior, and hopelessness about the future, trouble sleeping, memory problems, trouble concentrating, and efforts to avoid thinking or talking about his trauma. He is emotionally unstable, irritable, angry, shameful, guilty, easily startled or frightened, and dissatisfied with activities he once enjoyed. A thorough analysis has taken place that has proven that Holden Caulfield could perhaps have the predicted diagnosis.  The treatment I am going to plan out for Holden is helpful for mainly his psychological problems.

...Analyze combat and operational stress reactions (COSRs) Combat Stress Controlling combat stress is often the deciding factor between victory and defeat in all forms of human conflict. Stressors are a fact of combat, and you and your Soldiers will face them. Controlled combat stress can call forth stress reactions of loyalty, selflessness, and heroism. Conversely, uncontrolled combat stress causes erratic or harmful behavior that disrupts or interferes with the accomplishment of a unit’s mission. Any uncontrolled combat stress can impair mission performance and may bring disgrace, disaster, and defeat. The art of war aims to impose so much stress on enemy soldiers that they lose their will to fight. Both sides try to do this and at times accept severe stress themselves in order to inflict greater stress on the enemy. To win, you must control combat stress. The word “control” is better than the word “manage” to emphasize the active steps that leaders, supporting personnel, and individual Soldiers must take to keep stress within an acceptable range. This does not mean that control and management are mutually exclusive terms. Management is, by definition, the exercise of control. Within common usage, however, and especially within Army usage, management has the connotation of being a somewhat detached, number–driven, higher echelon process rather than a direct, inspirational, leadership process. Stress is the body’s and mind’s process for dealing with uncertain change...

Posttraumatic Stress Disorder

...Posttraumatic Stress Disorder Abstract Posttraumatic stress disorder is a common and disabling disorder that develops as a consequence of traumatic events and is characterized by distressing re-experiencing portions of the trauma, avoidance of reminders, emotional numbing and hyper-arousal. In spite of the deleterious impact of PTSD within the U.S. military, our current understanding of the human pathophysiology governing the divergent paths associated with extreme stress response the remains unabated. Given the widespread phenomenon of ‘trauma’, it begs the question of whether or not preexisting features accompany some suffers who have developed PTSD and why others may or may not face the same effect. Much research has been conducted in this arena and it seems that no one researcher has a definitive cause, much less a standardized treatment approach for PTSD sufferers.   Posttraumatic Stress Disorder Posttraumatic stress disorder (PTSD) develops as a consequence of traumatic events such as interpersonal violence, disaster, severe accidents, or other life-threatening experiences. The most common characteristics of PTSD are the re-experiencing of symptoms linked to a specific event. Patients involuntary re-experience aspects of the traumatic event in a very vivid and distressing way. This includes: flashbacks, in which the person acts or feels as if the event were recurring, nightmares, intrusive images or other sensory impressions from the event. For example...

Stress

...Executive Summary Table of Content 1.0 Introduction Newth (2011) defines stress as an applied force or systems of forces which tend to strain an individual body in such a way that the particular individual experiences the feeling of ‘not being in control’. From the psychology point of view, stress can also be considered as a reaction to a stimulus that disturbs an individual’s physical or mental equilibrium (Psychology Today, 2014). Given that numerous stressful events are capable of triggering different responses in human beings, it is fair to say that stress is an event that is omnipresent in every part of life; and hence is worth exploring. Significant investigations and debates into the issues of stress, its determinants and who are generally susceptible to stress have been rife in recent decades (Langan-fox and Cooper, 2011). The general consensus is that frequent exposure to traumatic events is the vital stressor for stress and everyone is susceptible to traumatic events and stress (Langan-fox and Cooper, 2011). Externalisation of stressful behaviours as a result of being exposed to traumatic events such as severe neglect, abuse and repeated violence is clinically termed as Post Traumatic Stress Disorder (PTSD) (Royal College of Psychiatrists, 2013). It has been maintained that PTSD creates psychological and physical imbalances in sufferers; and affects their physical and mental well-being negatively (Royal College of Psychiatrists, 2013). From this standpoint...

Why Is War Never Good

...The first reason on why war is never good is because of the effect it has on the participants and their families. When soldiers arrive from war they are not mentally stable and face difficulties when trying to participate in regular activities. Not to mention, they also suffer from physical problems such as asthma, tuberculosis and other complicated health problems. The main causes to these health problems are the dangerous chemicals that soldiers are exposed to when fighting in many wars. In addition to this, soldiers also risk their lives and can get physically hurt during a war. Soldiers are not mentally stable and suffer from depression and other mental problems. Mostly common is the post-traumatic stress disorder. Post-traumatic stress...

Traumatic Brain Injuries

...Traumatic Brain Injuries (TBI) can have major and long lasting effects on the cognition of the people who suffer from them. Cognition is the mental processes involved in perception, attention, memory, language, problem solving, reasoning, and decision making (Goldstein, 2015). Previous research on individuals who had TBI is wide and varied. There is always evolving and new information being produced in this area of research. The US Military has also taken an interest in this area, as the instances of service members suffering from Post-Traumatic Stress Disorder (PTSD) correlated with a previous TBI is high (Summerall, 2007).

PTSD In Paul Baumer's All Quiet On The Western Front

...Imagine that you experienced something terrible, unimaginable. No one understands you. You have no one to talk to. You live in fear. How would you handle it? “The brave men and women, who serve their country and as a result, live constantly with the war inside them, exist in a world of chaos. But the turmoil they experience isn’t who they are; the PTSD invades their minds and bodies.” Robert Koger said this thought-provoking quote in his book, Death´s Revenge. The quote captures the chaotic and fearful nature of PTSD. PTSD, or Post Traumatic Stress Disorder, is a mental health problem that some people develop after experiencing or witnessing a life-threatening event, like combat, a natural disaster, a car accident, or sexual assault ("What Is PTSD?"). People who suffer from PTSD can have various symptoms. They often will have vivid flashbacks of the event that triggered the...

...can't quite put my finger on makes my heart race and puts me back in combat mode. These are just some of the problems soldiers face when they return from war. It is something called PTSD ( Post Traumatic Stress Disorder). In this paper I will discuss the definition of PTSD, soldiers committing crimes, and suicides after deployment. Also, what kinds of treatments that are out there for soldiers. Finally, we will discuss the struggles of a soldier returning home. Post Traumatic Stress Disorder (PTSD) is a condition resulting from exposure to direct or indirect threat of death, serious injury, or a physical threat. Events that can cause PTSD are called "stressors” and may include natural disasters, accidents or deliberate man-made events/disasters, including war. Symptoms of PTSD can include recurrent thoughts of a traumatic event, reduced involvement in work or outside interests, emotional numbing, hyper-alertness, anxiety and irritability. The disorder can be more severe and longer lasting when the stress is human initiated action (example: war, rape, terrorism) (Veterans Affairs.gov 2010). Crime is always high next to a active duty post. It is plain math. You have your normal amount of civilians, and you add the total amount of soldiers to that.

The toll can be seen in many different forms such as emotional and mental disorders. These types of disorders can destroy an individual from the inside, out. Now multiply those symptoms by the number of deployments some soldiers have endured and the chance for mental disorders like post- traumatic stress disorder (PTSD) increase drastically. There have been many studies done to determine the correlation between the number of deployments and PTSD. One particular study was conducted with the help of the US Navy Bureau of Medicine and Surgery under the Wounded, III, and Injured/Psychological Health/Traumatic Brain Injury Program to determine if the amount of dwell time a soldier has between deployments decreases PTSD. It has been shown by this study and several others that...
