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 scene of the event, the strength of the individual’s reaction, the control or lack of control over the event, and how much help and support an individual receives after an event. All of these factors may influence the development of PTSD. According to the National Institute of Mental Health (NIMH), PTSD affects about 7.7 million American adults. The disorder was first

Usually the disorder begins within three months of this experience, although the disorder can take years to appear in some cases. Common PTSD effects include extreme fear, depression, and anxiety. Generally, post-traumatic stress lasts only for a short period (6 months) but in some cases the disorder can become chronic and last for years. Post-traumatic stress affects both men and women, and can affect children as well.

...Posttraumatic stress disorder (PTSD), once called shell shock or battle fatigue syndrome, is a serious condition that can develop after a person has experienced or witnessed a traumatic or terrifying event in which serious physical harm occurred or was threatened. PTSD is a lasting consequence of traumatic ordeals that cause intense fear, helplessness, or horror, such as a sexual or physical assault, the unexpected death of a loved one, an accident, war, or natural disaster. Families of victims can also develop PTSD, as can emergency personnel and rescue workers. Most people who experience a traumatic event will have reactions that may include shock, anger, nervousness, fear, and even guilt. These reactions are common; and for most people, they go away over time. For a person with PTSD, however, these feelings continue and even increase, becoming so strong that they keep the person from living a normal life. People with PTSD have symptoms for longer than one month and cannot function as well as before the event occurred. Symptoms of PTSD most often begin within three months of the event. In some cases, however, they do not begin until years later. The severity and duration of the illness vary. Some people recover within six months, while others suffer much longer. Symptoms of PTSD often are grouped into three main categories, including: Reliving: People with PTSD repeatedly relive the ordeal through thoughts and memories of the trauma.
