Physio and psych trauma/stress impact on health outcomes Flashcards
Four major pathways people look to when explaining the link between psych trauma/stress and chronic illness
HPA axis
sympathetic nervous system
inflammatory processes
injury sustained during the trauma
Foour major/common classes of chronic illness linked to exp of psych stress/trauma
cardiovascular disease
diabetes
GI conditions
cancer
In addition to trauma-based psych tx’s what are three adduct treatments that can help to down regulate the inflammatory response?
long-chain omega 3 fatty acids
sleep interventions
exercise interventions
In a nutshell, how do trauma expo’s impact the inflammatory system
trauma/stress primes the inflammatory response such that it is more likely to be engaged throughout the lifetime; lowers the threshold for activation
Researchers first noticed the connection between trauma and health outcomes related to what kinds of health conditions? when?
chronic pain syndroms
in the 1980’s
(this isn’t a new idea)
the relationship between trauma and negative health outcomes seems dose dependent; true or false?
true
(e.g. In one study w/ women with PTSD and GI/chronic pain; the more severe the trauma the more severe the reported symptoms)
It is just childhood trauma that seems linked to negative health outcomes? true or false
False
there are studies that looked at both childhood experiences as well as trauma experiences in adulthood
What kinds of trauma seem linked to neg health outcomes?
All
Name the three, interrelated components of the stress response
release of catecholamines
HPA axis
and the immune response
what are the three catecholamines?
epinephrine
norepinephrine
dopamine
release of catecholamines triggers what?
activation of the HPA axis
Activation of the HPA axis causes what?
a chemical cascade (ultimately resulting tin the release of cortisol)
Hypothalamus –> CRH
Pituitary –> ACTH
Adrenal cortex –> cortisol
What kind of chemical is cortisol
glucocorticoid
Chronic activation/dysregulation of the HPA axis and sympathetic nervous system leads to
increased allostatic load (i.e. body “wear and tear”)
Whats the overarching conceptual model we use to think about the connection between trauma/PTSD and the stress response
Allostatis (McEwan, 1998)
Increased activation of the sympathetic nervous system and the HPA axis is commonly referred to as what?
the F-F-F response
in resp to both physio and psych stress, What does the immune system do to try to protect the body ?
realease proinfammatory cytokines
cytokines are meant to _______, but in excess they _____
heal wounds and fight infection
leave the body vulnerable to disease
