On October 22nd, Dr. Michael
Fanselow presented on stress enhanced fear learning (SEFL). This is used in
a rodent model to demonstrate the effects of PTSD on a person’s response to mild
stressors. Due to past trauma, the fear response to these stressors is triggered
easily even in cases of little threat. Fanselow also went into how this
impacted the lives of those who suffer from PTSD and how it impacts their everyday
life.
I was curious to see how PTSD impacted
one’s relationship with not only adverse stimuli but with positive stimuli as
well. I found an article on the effects of alcohol and how the brain associates
alcohol consumption after the trauma that occurred during intoxication. The article,
published in Clinical Psychology: Science & Practice, Debra Kaysen
discusses the effects that alcohol has on the development, severity, and recovery
of PTSD.
Though there are many varying
factors that play into the way alcohol consumption and PTSD in person who has
experienced trauma one interesting point that was brought up was the
motivational process that might be impacted by PTSD. First, they discuss that
alcohol, though raising one’s risk for traumatic experiences, may actually help
to prevent the formation of PTSD. When one consumes alcohol, it reduces one’s
response and arousal to trauma exposure. In doing so the low levels of fear may
impact the way a person processes trauma. Kaysen discusses the work of J. K. Langdon
and who the level of alcohol consumption completely changes the way a woman
develops fear conditioning. Those who had consumed low levels of alcohol before
an assault showed a higher level of fear conditioning than those who had
consumed high levels of alcohol. It is also discussed that alcohol may have an impact
on the recovery rate of a person from a traumatic experience. Those who were intoxicated
during a traumatic event had a slower rate of recovery.
Though it could be argued that alcohol, if involved
in the traumatic event/ events, may be seen as a trigger it was highlighted that
it may also have a satiating effect of the anxiety that one experiences. PTSD,
which is seen mostly for its negative effects on reward and motivation, may
actually have motivational effects on coping mechanisms such as substance abuse
and disassociation. I think that this is very interesting seeing as 70 percent of
the population experiences trauma in their lifetime and the substance abuse
problem in our country. Finding the connection between these may open a new
door to recovery seeing as if one is using drugs or alcohol to cope with trauma
then recovery is that much harder. By taking Fanselow’s research a step further
and looking into the state of the person while the trauma occurred it may also
impact how it is treated.
