PTSD et al Flashcards
ABC
DEF
airway breathing circulation
distress (reduce)
emotional (support)
family (remember)
distorted appraisal
perception of event distorted by prior experiences; interferes with meaning attached to situation
- biologic changes in brain may have been produced
shattered assumption
disruption of assumption that we live in a meaningful, safe world
- result: fear, helplessness
fear conditioning
all sensory stimulation coming into brain related to fear, anxiety.
sensitization
patient becomes increasingly sensitive over time; less arousal results in symptoms
amygdala
part of limbic system; associated with aggression, danger reactions
frontal cortex
turns fight-or-flight off when no longer needed
hypothalamus
command/control center when receiving stressful signals; receives input from amygdala especially
- engages autonomic nervous system (fight or flight
ptsd onset
- actual or threatened death, serious injury
- outside usual range of experience
initial response intense fear, horror
ptsd duration + persistent symptoms
1+ month of PERSISTENT
- re-experiencing
- avoidance of triggers
- numbing of responsiveness
- symptoms of increased arousal
constant switch between rest/arousal = feeling needy, helpless
crisis intervention
ptsd prevention!
immediately after event, exploring experience several times; “debriefing”
acute ptsd
< 3 months of symptoms
- symptoms typically occur within first 4 weeks
- usually only last 2-4 weeks
ptsd (timing classification)
symptoms past 2-4 weeks
chronic ptsd
3+ months of symptoms
ptsd with delayed onset
onset delayed 6+ months after event
preferred antidepressants for ptsd
TCA, MAOI
back up choice antidepressant for ptsd
SSRI - can cause CNS excitablity, stimulation
dissociative disorder: definition
severe interruption in consciousness after significant event, including:
- consciousness
- perception
- memory
- identity
they are considered extreme ptsd
dissociation
unconscious defense mechanism that protects individual from overwhelming anxiety
- can separate from emotion
depersonalization, derealization
feeling detached from body, body parts, mental processes, environment
flat affect and unemotional presenting demeanor demonstrates incongruence between inner thoughts and outward appearance
mean age of onset is 16 years of age
< 20% after age 20
dissociative amnesia
Inability to recall important personal information
- NOT related to medical etiology
- localized, selective, or global (generalized)
- forgotten events can span minutes to decades
- single episodes predispose pt to future episodes
sx may resolve rapidly if removed from the stressful situation, others may persist for long periods. may gradually recover the dissociated memories years later.
dissociative amnesia: localized
loss of memory during a period of time
dissociative amnesia: selective
loss of pieces of memory during a period of time (remembers some parts and not others)
dissociative amnesia: global/generalized
complete loss of memory
onset: sudden
