Clinical Trial Summary
This is a pilot randomized controlled trial (RCT) for Veteran participants with alcohol use
disorder co-occurring with mild traumatic brain injury and/or post-traumatic stress disorder.
The treatment intervention is repetitive Transcranial Magnetic Stimulation (rTMS) and the
goal is to reduce alcohol craving with this treatment. The study will enroll 20 Veteran
participants. Half of these participants will receive real rTMS and half of the participants
will receive placebo rTMS. rTMS treatment will be provided over 10 sessions that will occur
once every weekday for 2 weeks. Veteran participants will then complete follow-up phone calls
to further evaluate alcohol craving and other symptoms.
Description:
Mild traumatic brain injury (mTBI), post-traumatic stress disorder (PTSD) and alcohol use
disorder (AUD) are high priority disorders for the Department of Veterans Affairs (VA), in
part, because these disorders rarely occur in isolation. The co-occurrence compounds brain
impairment and negatively impacts symptom presentation and rehabilitation effectiveness.
Veterans with co-occurring AUD, mTBI and/or PTSD have few effective treatment options. Thus,
treatment development for these Veterans is of great need. The aim of this protocol is to
examine safety, feasibility, and the behavioral and neural effects of an repetitive
transcranial magnetic stimulation (rTMS) intervention for Veterans with AUD and co-occurring
mTBI and/or PTSD. Behavioral and neural effects of rTMS will be examined after the first rTMS
session and after the last rTMS session. The investigators hypothesize that the rTMS
intervention will be 1) safe, 2) feasible and 3) efficacious. Specifically, the investigators
hypothesize that there will be no adverse events related to the rTMS intervention. The
investigators hypothesize that all participants enrolled will successfully complete all rTMS
sessions. The investigators hypothesize that participants treated with active rTMS, relative
to placebo rTMS, will have reduced alcohol craving severity levels. Finally, the
investigators hypothesize that participants treated with active rTMS relative to placebo rTMS
will have reduced brain activation in response to alcohol cues and improved functional
connectivity after the last rTMS session. This is a prospective, pilot, double-blind
randomized controlled trial of the intervention rTMS. There will be 2 groups of Veterans with
AUD and co-occurring mTBI and/or PTSD those given 1) active rTMS and those given 2) placebo
rTMS. Targeted enrollment for this study is 20 Veterans: n=10 active rTMS and n=10 placebo
rTMS. Participants will be screened for safety and evaluated on mental health-related
behavioral measures. Eligible participants will be randomized to receive active or placebo
rTMS. Participants will then complete motor thresholding (MT) to determine rTMS intensity.
Participants will then complete 10 sessions of rTMS. These sessions will be completed once
daily on week days over two weeks. TMS pulses will be applied to the left DLPFC at 10Hz rate,
4.9 seconds per train, with inter-train interval of 30 seconds, and a total of 20 trains per
session. After the 10th rTMS session, participants will complete an MRI which will last
approximately 1hour. A sub-sample of participants will complete an MRI immediately after the
first rTMS session. Participants will also repeat the mental health behavioral measures after
the last rTMS session. Participants will complete follow-up phone interviews to assess for
alcohol craving, mTBI symptoms and PTSD symptoms at one day, one week and one month
post-rTMS. Completion of this study is an essential first step towards treatment development
for Veterans with co-occurring AUD, mTBI and/or PTSD.
