What is PTSD?
Exposure to actual or threatened death, serious or sexual violence in which the sense of personal safety is threatened:
- Direct experiencing of traumatic event(s)
- Witnessed in person the events as it occurred to others
- Learning that the traumatic events occurred to person close to them
- Experiencing repeated or extreme exposure to aversive details of trauma
Is PTSD uniquely for threat to physical self?
yes
List of Presence of 1 or more intrusive ex after the event in PTSD:
- Recurrent, involuntary and intrusive memories of event
- Recurrent trauma-related nightmares
- Dissociative reactions
- Intense physiologic distress at cue exposure
- Marked physiological reactivity at cue exposure
List of Persistent avoidance by 1 or both in PTSD:
- Avoidance of distressing memories, thoughts or feelings of the event(s)
- Avoidance of external reminders of that arouse memories of event(s) e.g. people, places, activities
what is a key criteria of PTSD?
re-experiencing involuntary of the events (nightmares, flashbacks)
- Flashbacks : where the person re experiences the event even tho they are not there, something triggers the memory, but it doesn’t feel like a memory they feel like they are back there.
Flashbacks uniquely related to PTSD.
Internal experienced, might not see them reliving it.
- Waking nightmares- while they are awake. Can get these without PTSD.
What is complex PTSD:
kids with trauma, developed permanent physiological high arousal. Ex: huge startle reflex. Ends up in neurological disorders later in life.
what is a theory about PTSD?
always in flight or flight mode
What are the PTSD Changes in Cognitions and Mood?
- Inability to remember an important aspect of the traumatic event(s)
- Persistent distorted cognitions about cause or consequence of event that lead to blame of self or others
- Persistent negative emotional state
- Marked diminished interest
- Feeling detached from others
- Persistent inability to experience positive emotions
What makes it more likely to get PTSD?
- Not processing what happened. People who look like they’ve got nothing, no trauma, seem fine- ones we worry about the most.
- PTSD can start even one year after the trauma.
- Idea that they should’ve been able to prevent it (blaming self)
Is everyone with PTSD angry?
- Not everybody with PTSD becomes angry, but they become emotionally intense in some way.
- Cops scared of them bc they don’t know how they will react.
- Symptoms like depression (diminished interest, detached, no positive emotions)
What are the PTSD Changes in Arousal and Reactivity?
- Irritable behavior and angry outbursts
- Reckless or self-destructive behavior
- Hypervigilance (always imagining its gonna happen again)
- Exaggerated startle response
- Problems with concentration
- Sleep disturbance
What is the epidemiology in PTSD?
- 7-9% of general population
- 60-80% of trauma victims
- 30% of combat veterans
- 50-80% of sexual assault victims
- Increased risk in women, younger people
- Risk increases with “dose” of trauma, lack of social support, pre-existing psychiatric disorder
When is there greater risk to get PTSD?
- Risk is greater the more severe the trauma.
- Greater risk for women bc more vulnerable to assault.
- Men tend to be in situations where more likely to experience trauma (war).
What are the comorbidities of PTSD?
- Depression
- Other anxiety disorders
- Substance use disorders
- Somatization
- Dissociative disorders
What is Acute Stress Disorder?
- Similar exposure as in PTSD
- Presence of >9 of 5 categories of intrusion, negative mood, dissociation, avoidance, and arousal related to the trauma.
- Duration of disturbance is 3 days to 1 month after trauma
- Causes significant impairment
- Does not last anything longer than a month.
Less severe in time and a little bit in symptoms (but symptoms could still be severe)
-prob won’t get flashbacks
-it does cause a significant impairment for the month.
What are the Critics of the PTSD definition?
- PTSD as a homogenous response to trauma BUT not all individuals will develop PTSD.
- Looks at the event, and not at the individual himself
- Not everybody exposed to the trauma get PTSD. Individual differences
What are the PTSD Risk Factors Pre trauma?
- Genetic Predisposition
- Neurological Vulnerabilities
- Developmental Factors
- Psychological Vulnerabilities
- Cognitive Vulnerabilities
What are the PTSD Risk Factors During Trauma?
- Peritraumatic Dissociation
- Cognitive Appraisal
- Biological Reaction
What are the PTSD Risk Factors Post Trauma ?
- Coping
- Social Support
What are the genetic predispositions of PTSD?
Twin study of Vietnam veterans: heritability of .40 (True et al., 1999, 1993)
What is inherited? We don’t rly know, prob arousability. Small component of variability, nothing major.
What are the Neurological vulnerabilities in PTSD?
- Low cortisol levels
- Increased blood flow in left hippocampus
- Amygdala activation with PTSD
- Smaller hippocampal volume as a vulnerability factor for developing PTSD symptoms.
