Introduction
Post-traumatic stress disorder (PTSD) is a widely talked about topic, what with the wars in Iraq and Afghanistan still going on. Soldiers returning from deployment are at a higher risk due to the events that they live through while overseas. With the topic being as well-known as it is due to the wars, it’s no wonder that it has caused quite a push in the psychology/neuropsychology field to fully understand what PTSD really is and where it lies within the person. To figure out where within the brain PTSD actually effect lies the clue as to how to understand it better and possibly find a way to make treatment better and hopefully more specialized to the individual instead of a blanket diagnosis and treatment.
The research conducted thus far has indicated that there are three main areas in the brain that are affected the most by PTSD. The areas affected that will be discussed are the hippocampus, amygdala, and the anterior cingulate cortex. Each area mentioned have been hypothesized about and studied. PTSD does not just affect soldiers, so research has been done with people that have survived sarin attacks, police officers, trapped coal miners, sexual and physical abuse survivors. Keeping the pool of subjects studied wide and varied reflects better on the population as a whole, as anyone can fall prey to PTSD. Also, with the subjects varying it allows researchers to get a more broad view of the disorder and if people are pre-disposed to getting PTSD or not.
Diagnostic Criteria
To study PTSD and the brain, one must look at the criteria of PTSD and how it affects the individual day to day. Since there are several parts of the brain affected by the disorder, it makes sense that the regions affected correlate ...

Post-Traumatic Stress Disorder or PTSD is a psychological disorder that is brought about after encountering a traumatic experience. This disorder can vary between mild and extreme severity in symptoms and effect on the suffering patient. It’s caused by hyper aroused state in the brain, using a magnetoencephalography
Post Traumatic Stress Disorder (PTSD), originally associated with combat, has always been around in some shape or form but it was not until 1980 that it was named Post Traumatic Stress Disorder and became an accredited diagnosis (Rothschild). The fact is PTSD is one of many names for an old problem; that war has always had a severe psychological impact on people in immediate and lasting ways. PTSD has a history that is as long and significant as the world’s war history - thousands of years. Although, the diagnosis has not been around for that long, different names and symptoms of PTSD always have been. Some physical symptoms include increased blood pressure, excessive heart rate, rapid breathing, muscle tension, nausea, diarrhea, problems with vision, speech, walking disorders, convulsive vomiting, cardiac palpitations, twitching or spasms, weakness and severe muscular cramps. The individual may also suffer from psychological symptoms, such as violent nightmares, flashbacks, melancholy, disturbed sleep or insomnia, loss of appetite, and anxieties when certain things remind them such as the anniversary date of the event (Peterson, 2009).
Post-Traumatic Stress Disorder or PTSD is a psychological disorder that’s brought about after encountering a traumatic experience. This disorder can vary between mild and extreme severity in symptoms and effect on the suffering patient. It’s caused by a hyper-aroused state in the brain, using a magnetoencephalography machine “We could see heightened arousal that was maintained in the PTSD-afflicted men and not in the men who don’t suffer from the illness” (The Globe and Mail, Image of PTSD). Therefore, most commonly the individual will present with suicidal tendencies, making this condition a danger to anyone who is
The lifetime prevalence of PTSD in the general population is 6-8% and increases to 20-30% for victims of severe traumatic events (Desmedt et al., 2015). PTSD resulting from combat-related trauma is a popular topic discussed throughout the media and is commonly adapted into characters in movies and television. In this paper, post-traumatic stress disorder portrayed in the movie Brothers will be critiqued and compared to the neural correlates that underlie symptoms of the disorder in neuropsychological literature.
The current criteria for assessment of PTSD is only suitable if criterion A is met. Every symptom must be bound to the traumatic event through temporal and/or contextual evidence. The DSM-5 stipulates that to qualify, the symptoms must begin (criterion B or C) or worsen (symptom D and E) after the traumatic event. Even though symptoms must be linked to a traumatic event, this linking does not imply causality or etiology (Pai, 2017, p.4). The changes made with the DSM-5 included increasing the number of symptom groups from three to four and the number of symptoms from 17 to 20. The symptom groups are intrusion, avoidance, negative alterations in cognition and mood, and alterations in arousal and
Post-Traumatic Stress Disorder, also known as PTSD, is an anxiety disorder that can develop after a traumatic event (Riley). A more in depth definition of the disorder is given by Doctor’s Nancy Piotrowski and Lillian Range, “A maladaptive condition resulting from exposure to events beyond the realm of normal human experience and characterized by persistent difficulties involving emotional numbing, intense fear, helplessness, horror, re-experiencing of trauma, avoidance, and arousal.” People who suffer from this disease have been a part of or seen an upsetting event that haunts them after the event, and sometimes the rest of their lives. There are nicknames for this disorder such as “shell shock”, “combat neurosis”, and “battle fatigue” (Piotrowski and Range). “Battle fatigue” and “combat neurosis” refer to soldiers who have been overseas and seen disturbing scenes that cause them anxiety they will continue to have when they remember their time spent in war. It is common for a lot of soldiers to be diagnosed with PTSD when returning from battle. Throughout the history of wars American soldiers have been involved in, each war had a different nickname for what is now PTSD (Pitman et al. 769). At first, PTSD was recognized and diagnosed as a personality disorder until after the Vietnam Veterans brought more attention to the disorder, and in 1980 it became a recognized anxiety disorder (Piotrowski and Range). There is not one lone cause of PTSD, and symptoms can vary from hallucinations to detachment of friends and family, making a diagnosis more difficult than normal. To treat and in hopes to prevent those who have this disorder, the doctor may suggest different types of therapy and also prescribe medication to help subside the sympt...
Hundreds of thousands of United States veterans are not able to leave the horrors of war on the battlefield (“Forever at War: Veterans Everyday Battles with PTSD” 1). Post-traumatic stress disorder (PTSD) is the reason why these courageous military service members cannot live a normal life when they are discharged. One out of every five military service members on combat tours—about 300,000 so far—return home with symptoms of PTSD or major depression. According to the Rand Study, almost half of these cases go untreated because of the disgrace that the military and civil society attach to mental disorders (McGirk 1). The general population of the world has to admit that they have had a nightmare before. Imagine not being able to sleep one wink because every time you close your eyes you are forced to relive memories from the past that you are trying to bury deep. This is what happens to the unfortunate men and women who are struggling with PTSD. Veterans that are struggling with post-traumatic stress disorder deserve the help they need.
With people who are suffering from PTSD their brain is still in overdrive long after the trauma has happened. They may experience things like flashbacks, nightmares, hallucinations, panic attacks, and deep depression. They tend to avoid things that remind them of their trauma and are constantly on high alert waiting for the next possible traumatic event to take place; in events such...
Until now, there has not been a definite understanding of how post-traumatic stress disorder occurs in the brain. The exploration into its pathophysiology is fairly recent. However, there is research around it discussing about PTSD’s pathophysiology and coming to a complete understanding. In a normal person without the disorder, a stress hormone, adrenaline, releases from the body and prepares it to flee o...

At least 50% of all adults and children are exposed to a psychologically traumatic event (such as a life-threatening assault or accident, humanmade or natural disaster, or war). As many as 67% of trauma survivors experience lasting psychosocial impairment, including post-traumatic stress disorder (PTSD); panic, phobic, or generalized anxiety disorders; depression; or substance abuse.(Van der Kolk, et al, 1994) Symptoms of PTSD include persistent involuntary re-experiencing of traumatic distress, emotional numbing and detachment from other people, and hyperarousal (irritability, insomnia, fearfulness, nervous agitation). PTSD is linked to structural neurochemical changes in the central nervous system which may have a direct biological effect on health, such as vulnerability to hypertension and atherosclerotic heart disease; abnormalities in thyroid and other hormone functions; increased susceptibility to infections and immunologic disorders; and problems with pain perception, pain tolerance, and chronic pain.(Fesler, 1991) PTSD is associated with significant behavioral health risks, including smoking, poor nutrition, conflict or violence in intimate relationships, and anger or hostility.
PTSD was such a horrible sickness because it embedded traumatic events in a soldiers mind. So later on this memory impeded a soldier enjoyment of life. Certain smell, sights and taste a soldier experienced triggered their memory making them recall those horrifying moments when their friend was brutally slaughtered. When these memories occurred soldiers would lose themselves. They would would break down and question themselves, ‘What could I have done to save him? Why did he die and not me? The guilt was so great that for many that they simply killed themselves. However, this was only one of the horrible effects of PTSD. Another
