Specifier: With dissociative symptoms
The individual’s symptoms meet the criteria for PTSD, and in addition, in response to the stressor, the individual experiences persistent or recurrent symptoms of either:
Depersonalization
Derealization
Depersonalization
Persistent or recurrent experiences of feeling detached from one’s mental processes or body
Feeling as if one were an outside observer of one’s mental processes or body
e. g. feeling as though one were in a dream
e. g. feeling a sense of unreality of self or body or of time moving slowly
Derealization
Persistent or recurrent experiences of unreality of surroundings
The world around the individual is experienced as unreal, dreamlike, distant, or distorted
Specifier: With delayed expression
If the full diagnostic criteria are not met until at least 6 months after the event
Although the onset and expression of some symptoms may be immediate
PTSD clinical presentation
Highly variable
In some individuals, fear-based re–experiencing, emotional, and behavior symptoms may predominate
And others, anhedonic or dysphoric mood states and negative cognitions may be most distressing
In some others, arousal and reactive-externalizing symptoms are prominent, while in others dissociative symptoms predominate
Some individuals exhibit combinations of these symptom patterns
Traumatic events
Exposure to war as a combatant or civilian
Threatened or actual physical assault
Threatened or actual sexual violence
Kidnapping
Being taken hostage
Terrorist attack
Torture
Incarceration as a prisoner of war
Natural or man-made disasters
Severe motor vehicle accidents
Intrusive recollections versus depressive ruminations
Intrusive recollections in PTSD apply only to involuntary and intrusive distressing memories
The emphasis is on recurrent memories of the event that usually include sensory, emotional, or physiological behavioral components
PTSD: Prevalence
Projected lifetime risk 8.7%
12 month prevalence 3.5%
Highest rates (1/3 - 1/2 of those exposed) are found among survivors of rape, military combat and captivity, and ethnically or politically motivated internment and genocide
Higher rates of PTSD among Latinos, African-Americans, and American Indians
Lower rates of PTSD among Asian Americans
PTSD: Development
PTSD can occur at any age, beginning after the first year of life
Symptoms usually begin within the first 3 months after the trauma, although there may be a delay of months, or even years before criteria for the diagnosis are met
Previously called “delayed onset” but is now called “delayed expression” with the recognition that some symptoms typically appear immediately and that the delay is in meaningful criteria
