Concept of trauma in Post-traumatic stress disorder (PTSD)

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 there was serious physical harm or threat. PTSD is a lasting consequence of traumatic ordeals that cause intense fear, helplessness, or horror. Examples of things that can bring on PTSD include sexual or physical assault, the unexpected death of a loved one, an accident, war, or natural disaster. Families of victims can develop PTSD, as can emergency personnel and rescue workers

Everyone reacts to traumatic events differently. Each person is unique in their ability to manage fear, stress and the threat posed by a traumatic event or situation. For that reason, not everyone who has a trauma will develop PTSD. Also, the type of help and support a person receives from friends, family members, and professionals following the trauma may impact the development of PTSD or the severity of symptoms.

PTSD was first brought to the attention of the medical community by war veterans; hence the names shell shock and battle fatigue syndrome. However, anyone who has had a traumatic event can develop PTSD. People who were abused as children or who have been repeatedly exposed to life-threatening situations are at risk for developing PTSD. Victims of trauma related to physical and sexual assault face the greatest risk for PTSD.

You may be more likely to develop PTSD after a traumatic event if you have a history of other mental health problems, have blood relatives with mental health problems, or have a history of alcohol or drug abuse.

The American Psychiatric Association (APA) played an important role in defining trauma. Diagnostic criteria for traumatic stress disorders have been debated through several iterations of the Diagnostic and Statistical Manual of Mental Disorders (DSM) with a new category of Trauma- and Stressor-Related Disorders, across the life-span, included in the recently released DSM-V (APA, 2013). Measures and inventories of trauma exposure, with both clinical and research applications, have proliferated since the 1970’s.

With the advances in neuroscience, a biopsychosocial approach to traumatic experiences has begun to delineate the mechanisms in which neurobiology, psychological processes, and social attachment interact and contribute to mental and substance use disorders across the life-span.

Individual trauma results from an event, series of events, or set of circumstances that is experienced by an individual as physically or emotionally harmful or life threatening and that has lasting adverse effects on the individual’s functioning and mental, physical, social, emotional,
or spiritual well-being
