Flashcards in CM: Effects of Trauma Deck (15):
1

What is the effect of trauma on the brain?

medical prefrontal cortex interacts w limbic system which sends signals to HPA axis to release cortisol via ACTH
signals to locus ceruleus to release NE and DA --> sympathetic nervous response

2

What is the fight, flight or freeze response?

increased HR, sweating, persons being alert, redistribution of blood to heart, brain and skeletal muscles

3

What is criterion A?

exposure to actual or threatened death, serious injury, or sexual violation in one or more of the following ways: direct experience, witnessing it, learning it occurred to a loved one, repeated exposure to aversive details of event (not seeing on TV unless work related)
necessary for acute stress disorder and PTSD

4

What symptoms are required to diagnose acute stress disorder?

presence of nine or more symptoms from any of five categories: intrusion, negative mood, dissociation, avoidance, arousal, beginning or worsening after traumatic event occurred

5

What are intrusion symptoms of acute stress disorder?

intrusive memories
nightmares
flashbacks
panic symptoms in response to cues

6

What are dissociative symptoms of acute stress disorder?

altered sense of reality
inability to remember important aspect of traumatic event

7

What are avoidance symptoms of acute stress disorder?

efforts to avoid distressing memories, thoughts, feelings associated with trauma
efforts to avoid external reminders

8

What are arousal symptoms of acute stress disorder?

sleep disturbance, irritable behavior or angry outbursts, hypervigilance, problems w concentration, exaggerated startle response

9

What is the timeline of symptoms needed for diagnosis of acute stress disorder? other requirements?

3 days to 1 month after trauma exposure
causes distress or impairment in social, work, etc
not attributable to substance, another medical condition, other brief psychotic disorder

10

What is the only difference between acute stress disorder and PTSD?

symptoms are the same (except PTSD doesn't have dissociative symptoms) but present longer than 1 month

11

What are specifiers for PTSD?

w dissociative symptoms - depersonalization, derealization
w delayed expression - diagnostic criteria not met until at least 6 mos after event

12

attempts at self-soothing - clingy relationships
self destructive
fear of abandonment or rejection
increased risk of developing mood, anxiety and substance disorders
