Dr. Herrold’s Transcranial magnetic
stimulation: potential treatment for co-occurring alcohol, traumatic brain
injury and posttraumatic stress disorders focuses on intertwining the treatment of Alcohol
Use Disorder (AUD), Mild Traumatic Brain Injury (mTBI), and post-traumatic
stress disorder (PTSD). She mentions that repetitive transcranial magnetic
stimulation (rTMS) has been a noninvasive method to treating these conditions separately
but not looked at in unison. AUD is most commonly found when a person observes impairments
in their control, withdrawal, and social relationships due to intense craving
of alcohol. On the other hand, PTSD can be a result of trauma related
cues (like an explosion or similar physical act).
Once again,
an advantage of the rTMS is that it is noninvasive and can be used either
excitatory or inhibitory. This method of treatment focuses on both the
intensity (Motor evoked potential) along with its frequency, which resides in number
of pulses per second. Dr. Herrold seeks to treat the dorsolateral prefrontal
cortex of these patients, since this section of the brain affects both
depression and anxiety in patients. She finds that the H-coiled rTMS actually
decreases PTSD significantly with the gradual increase of the frequency of it
over time. Yet, an issue seen is that rTMS stimulating deeper subcortical
structures intensifies on the cortical surface, leading to possible seizures.
As we can
see, rTMS has proven to be effective with slight fear of possible seizures. However,
this fear is not nearly met with the same skepticism as other treatments being
offered recently. One that clearly stood out to me was Dave Philipps’ New
York Times 2016 article, “F.D.A Agree to New Trials for Ecstasy as a
Relief for PTSD Patients.” The article was published explaining the recent
use of MDMA (ecstasy) to treat patients suffering with PTSD. Many physicians in
the article state how traditional methods of prescription drugs and
psychotherapy have had little to sometimes no effect on patients. However, patients
given MDMA often showed immediate signs of improvement and control within their
lives, leading to extinction of PTSD within a year. Similar to Dr. Herrold’s
research, many PTSD patients had AUD problems, which were repressed due to the
MDMA addition.
A few
concerns arise with both of these treatments. In regard to rTMS, one must make
sure that cortical surfaces are not applied with such high intensities that could
result with a seizure. On the other hand, MDMA is far messier. It is a drug
known to increase extremely large amounts of serotonin in body. This results in
a large sense of euphoria that leads to heightened sensation and emotions, repressing
negative emotions. However, once the drug’s effects fade away, the patient is
left feeling incredible down and could lead to a more pronounced depression.
