More trauma is associated with a […] rate of PTSD
More trauma is associated with a higher rate of PTSD
What role does the type of trauma have in the rates of PTSD development?
Those that are more personal physical affronts have higher rates (physical attack, threat wiht weapon, rape, …)
What are important factors related to the trauma that are risk factors for PTSD development?
Degree of controllability, predictability, perceived threat, and extent of injury
What are premorbid sociodemographic risk factors for PTSD?

Cognitive appraisal of trauma
What are premorbid characteristics of trauma exposure that are risk factors for PTSD?
Type
Amount/severity
Age at exposure
What are premorbid characteristics of the recovery environment that are risk factors for PTSD?
Low social support
Stressful life events
New traumas
What is “failure to recover” with respect to PTSD?
Normal stress response occurs to a trauma
Typically it shuts off, but there is a subset of people who do not recover
What are neurobiological models of PTSD?
ANS, noradrenergic system
HPA axis, cortisol
Serotonergic system
Neuroanatomy and neurocircuitry
Genetics
What is the role of cortisol on the fight-or-flight response?
Feeds back and shuts it down
What findings are seen in the noradrenergic system in PTSD patients?
Sustained hyperactivity of sympathetic nervous system (increased urinary excretion of NE, Epi and metabolites; Increased HR, BP, increased plasma NE)
Increased CNS NE activity/reactivity (Increased CSF NE levels and responses to stressors; α2 receptor antagonist causes flashbacks and increased autonomic responses)
What can potentially be a predictor of PTSD in trauma survivors?
HR at ER presentation
What do you see on dexamethasone suppression test in PTSD patients?
Exaggerated suppression of the HPA axis
