What causes PTSD?
Virtually any trauma, defined as an event that is life-threatening or that severely compromises the physical or emotional well-being of an individual or causes intense fear, may cause PTSD. Such events often include either experiencing or witnessing a severe accident or physical injury, receiving a life-threatening medical diagnosis, being the victim of kidnapping or torture, exposure to war combat or to a natural disaster, exposure to other disaster (for example, plane crash) or terrorist attack, being the victim of rape, mugging, robbery, or assault, enduring physical, sexual, emotional, or other forms of abuse, as well as involvement in civil conflict. Although the diagnosis of PTSD currently requires that the sufferer has a history of experiencing a traumatic event as defined here, people may develop PTSD in reaction to events that may not qualify as traumatic but can be devastating life events like divorce or unemployment.
What are PTSD risk factors and protective factors?
Issues that tend to put people at higher risk for developing PTSD include increased duration of a traumatic event, higher number of traumatic events endured, higher severity of the trauma experienced, having an emotional condition prior to the event, or having little social support in the form of family or friends. In addition to those risk factors, children and adolescents, females, minority groups and people with learning disabilities or violence in the home seem to have a greater risk of developing PTSD after a traumatic event.
What are PTSD symptoms and signs?
The following three groups of symptom criteria are required to assign the diagnosis of PTSD in the context of an individual who has a history of being exposed to an actual or perceived threat of death, serious injury, or sexual violence to self or others that does not involve exposure through media unless that is work related:
The emotional numbing of PTSD may present as a lack of interest in activities that used to be enjoyed (anhedonia), emotional deadness, distancing oneself from people, and/or a sense of a foreshortened future (for example, not being able to think about the future or make future plans, not believing one will live much longer). At least one re-experiencing symptom, one avoidance symptom, two negative changes in mood or thinking, and two hyperarousal symptoms must be present for at least one month and must cause significant distress or impairment in functioning in order for the diagnosis of PTSD to be assigned.
A similar disorder in terms of symptom repertoire is acute stress disorder. The major differences between the two disorders are that acute stress disorder symptoms persist from three days to one month after the trauma exposure, and a fewer number of traumatic symptoms are required to make the diagnosis as compared to PTSD.
In children, re-experiencing the trauma may occur through repeated play that has trauma-related themes instead of or in addition to memories, and distressing dreams may have more general content rather than of the traumatic event itself. As in adults, at least one re-experiencing symptom, one avoidance/numbing symptom, and two hyperarousal symptoms must be present for at least one month and must cause significant distress or functional impairment in order for the diagnosis of PTSD to be assigned. When symptoms have been present for three days to one month, a diagnosis of acute stress disorder (ASD) can be made.
Symptoms of PTSD that tend to be associated with C-PTSD include problems regulating feelings, which can result in suicidal thoughts, explosive anger, or passive aggressive behaviors, a tendency to forget the trauma or feel detached from one's life (dissociation) or body (depersonalization), persistent feelings of helplessness, shame, guilt, or being completely different from others, feeling the perpetrator of trauma is all powerful, and preoccupation with either revenge against or allegiance with the perpetrator, and severe change in those things that give the sufferer meaning, like a loss of spiritual faith or an ongoing sense of helplessness, hopelessness, or despair.
