Post Traumatic Stress Disorder ( Ptsd )

Studying the brain has been an affective result in finding out the various neurochemicals that are involved with PTSD. Brain imaging systems nowadays focus on two brain structures, the amygdala and the hippocampus. The amygdala is involved with how we learn about our fear and hippocampus plays a role with our memory formation. Some research focuses on a hormonal system known as hypothalamic-pituitary

Post-Traumatic Stress Disorder can do a range of things to the brain. Post-Traumatic Stress Disorder makes the victim continuously remember the event. It was originally known as “shell shock” where vets were struggling going through daily life. Finally after the Vietnam War Post-Traumatic Stress Disorder was “identified and given its name.” When these discoveries were made, proper treatment was then given to the victims. Research shows that

Research has indicated that people who have experienced and extreme amount of stress or traumatic event sometimes have a smaller hippocampus region of the brain in adults with chronic PTSD and early childhood trauma. This is the part of the brain that is responsible for memory. The reduction in size may be caused by a combination of the environment and genetics (NARSAD.com). People who are diagnosed with this disorder are more likely to have trouble with relationships, smoke cigarettes, abuse drugs and or alcohol use. If PTSD is left untreated it can have devastating lasting effects.

What is post-traumatic stress disorder? When most people think of the term post-traumatic stress disorder (PTSD) they think of war and returning soldiers. Even though this is true, post-traumatic stress disorder does not only develop in soldier’s returning from war. When you look at the definition of post-traumatic stress disorder (PTSD), you will see that it is a mental health condition that is triggered by either experiencing or witnessing a terrifying event. This means that post-traumatic stress disorder can be developed after any traumatic event or experience that one has gone through.

PTSD, or Post-traumatic Stress Disorder, is a psychiatric disorder that can occur following the experience or witnessing of a life-threatening events such as military combat, natural disasters, terrorist incidents, serious accidents, or physical or sexual assault in adult or childhood. Most survivors of trauma return to normal given a little time. However, some people will have stress reactions that do not go away on their own, or may even get worse over time. These individuals may develop PTSD. People who suffer from PTSD often relive the experience through nightmares and flashbacks, have difficulty sleeping, and feel detached or estranged, and these symptoms can be severe enough and last long enough to significantly impair the person’s daily life.

Post-Traumatic Stress Disorder or PTSD is a mental health condition that is generally classified as an anxiety disorder. It is often caused by a traumatic events or emotional trauma in one’s life that leads to terrifying flashbacks, nightmares and extreme anxiety. The main cause of this disorder is the conscious and subconscious fear-memories that have developed. In essence the ‘fight or flight” response that we all have is severely damaged, even when not in a stressful or dangerous situation those suffering from PTSD may feel stressed and in danger.

Those diagnosed with PTSD have shown a reduction in the volume of the hippocampus. The hippocampus helps humans remember new memories and then be able to recall them later, and also helps identify between past and present memories. The amygdala is another section of the brain affected by PTSD, and the amygdala is responsible for processing emotions and fear. The ventromedial prefrontal cortex is shown to have a decreased size in cases. The ventromedial prefrontal cortex regulates negative emotions like stress, anxiety, and fear. The strange behaviours of the patients diagnosed with PTSD can be explained by the damage to the brain. “Researchers believe that the brain changes caused by PTSD increase the tendency of a person developing other psychotic and mood disorders” (brainblogger.com). The brain is like a machine made up of small parts, and if one of these parts break, the machine does not function

Traumatic events also produce profound and lasting changes in physiological arousal, emotion, cognition, and memory. Moreover, traumatic events may result in the severance of these normally integrated functions from one another. Traumatized individuals may also suffer from the memories of the tragic or horrifying experiences they have undergone. Frequently, as a result of these many symptoms, it becomes inevitable for the individual to develop certain complications associated with trauma-related disorders, such as posttraumatic stress disorder.

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

Post-Traumatic Stress Disorder (PTSD) is a condition that occurs after one has been exposed to a traumatic event. Within the article, “Facts About Post-Traumatic Stress Disorder”, the number of war veterans who suffer from PTSD is introduced in the second sub-section as “about 30% of men and women who have spent time in war zones experience PTSD” (Facts about PTSD 1). This quote goes to

As stated above, war is the most common trauma that causes PTSD. For many Veterans, memories of their wartime

Posttraumatic Stress Disorder (PTSD) is "an anxiety disorder, characterized by distressing memories, emotional numbness, and hyper vigilance, that develops after exposure to a traumatic event" (Doyle-Portillo, Pastorino 490). Traumatic events include physical abuse, rape, military combat, death of a close friend or family member, natural disasters, or witnessing events such as terrorist attacks, a violent crime, or a horrible accident (Doyle-Portillo, Pastorino 490). All these different events lead men and women to have nightmares, flashbacks, and tormenting memories, especially the men who fought in the Vietnam War. Around "19% of Vietnam veterans developed PTSD at some point after the war" (Doyle-Portillo, Pastorino 491) from the events they witnessed out in the Vietnamese jungles during combat that it would have been highly unlikely for them not to develop PTSD.

Morris states that PTSD is often thought of as being a syndrome of remembering things too well. He adds that “the ones who ‘forget,’ they suffer later” (Morris 35).

It is the goal of this paper to demonstrate that the phenomenon of PTSD, despite the fact that its multiple emotional and psychosocial effects are constantly being debated, is soundly rooted in neurobiology, and that this aspect of PTSD lends support to the notion that brain = behavior.

The amygdala is known to learn from exposure to fear and store assessment of threat–related stimuli. The prefrontal cortex is involved in extinction and the retention of fear and is connected to the amygdala. Finally, the hippocampus encodes the context during fear learning process and sends it to the amygdala. People with PTSD have hyper-activity in the amygdala, while having hypo-activity in the prefrontal cortex and there is reduction of the hippocampus volume. This reduction may limit proper evaluation and categorization of the experience. A study on Vietnam soldiers revealed that lesions in the amygdala and prefrontal cortex resulted in the absence of PTSD. To get further into the molecular level studies been done on the hormonal system. “Stress is known to contribute to the pathogenesis of a variety of disorders, including the majority of psychiatric like major depression and posttraumatic stress disorder.” (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3825244/pdf/DM30-02-343616.pdf). Research has revealed evidence that a hormonal system known as the hypothalamic-pituitary-adrenal (HPA) axis is the one that gets disrupted in people with PTSD. The hormonal system is involved in normal stress reactions, so the disruption of this system in people with PTSD creates this “false alarm”. It has been suggested by some scientist that the dysfunction of the HPA system results in hippocampal damage in people with PTSD. Damage in the hormones is caused by damage to
