    Effects of traumatic brain injury and posttraumatic stress disorder on development of Alzheimer's disease in Vietnam Veterans using the Alzheimer's Disease Neuroimaging Initiative: Preliminary report
    (Elsevier, 2017-06) Weiner, Michael W.; Harvey, Danielle; Hayes, Jacqueline; Landau, Susan M.; Aisen, Paul S.; Petersen, Ronald C.; Tosun, Duygu; Veitch, Dallas P.; Jack, Clifford R., Jr.; Decarli, Charles; Saykin, Andrew J.; Grafman, Jordan; Neylan, Thomas C.; Department of Radiology and Imaging Sciences, IU School of Medicine
    Introduction Traumatic brain injury (TBI) and posttraumatic stress disorder (PTSD) have previously been reported to be associated with increased risk of Alzheimer's disease (AD). We are using biomarkers to study Vietnam Veterans with/without mild cognitive impairment with a history of at least one TBI and/or ongoing PTSD to determine whether these contribute to the development of AD. Methods Potential subjects identified by Veterans Administration records underwent an initial telephone screen. Consented subjects underwent clinical evaluation, lumbar puncture, structural magnetic resonance imaging, and amyloid positron emission tomography (PET) scans. Results We observed worse cognitive functioning in PTSD and TBI + PTSD groups, worse global cognitive functioning in the PTSD group, lower superior parietal volume in the TBI + PTSD group, and lower amyloid positivity in the PTSD group, but not the TBI group compared to controls without TBI/PTSD. Medial temporal lobe atrophy was not increased in the PTSD and/or TBI groups. Discussion Preliminary results do not indicate that TBI or PTSD increase the risk for AD measured by amyloid PET. Additional recruitment, longitudinal follow-up, and tau-PET scans will provide more information in the future.

    Mixed methods study examining work reintegration experiences from perspectives of Veterans with mental health disorders
    (2015) Kukla, Marina; Rattray, Nicholas A.; Salyers, Michelle P.; Department of Psychology, School of Science
    Recent findings have demonstrated that reintegration for Veterans is often challenging. One difficult aspect of reintegration—transitioning into the civilian workplace—has not been fully explored in the literature. To address this gap and examine work reintegration, this mixed methods study examined the perspectives of Veterans with mental health disorders receiving Department of Veterans Affairs healthcare. Forty Veterans rated factors that affect work success; participants also provided narratives on their most and least successful work experiences. We used t-tests and qualitative analysis to compare participants who did and did not serve in combat. Several themes relevant to work reintegration emerged in the narratives, particularly for Veterans who served in combat. An array of work difficulties were reported in the months following military discharge. In addition, Veterans who served in combat reported significantly more work barriers than Veterans who did not serve in combat, particularly health-related barriers. In conclusion, Veterans with mental health disorders who served in combat experienced more work reintegration difficulty than their counterparts who did not serve in combat. The role of being a Veteran affected how combat Veterans formed their self-concept, which also shaped their work success and community reintegration, especially during the early transition period.

    Transcranial magnetic stimulation: potential treatment for co-occurring alcohol, traumatic brain injury and posttraumatic stress disorders
    (2014-10) Herrold, Amy A.; Kletzel, Sandra L.; Harton, Brett C.; Chambers, R. Andrew; Jordan, Neil; Pape, Theresa Louise-Bender; Department of Psychiatry, IU School of Medicine
    Alcohol use disorder (AUD), mild traumatic brain injury (mTBI), and posttraumatic stress disorder (PTSD) commonly co-occur (AUD + mTBI + PTSD). These conditions have overlapping symptoms which are, in part, reflective of overlapping neuropathology. These conditions become problematic because their co-occurrence can exacerbate symptoms. Therefore, treatments must be developed that are inclusive to all three conditions. Repetitive transcranial magnetic stimulation (rTMS) is non-invasive and may be an ideal treatment for co-occurring AUD + mTBI + PTSD. There is accumulating evidence on rTMS as a treatment for people with AUD, mTBI, and PTSD each alone. However, there are no published studies to date on rTMS as a treatment for co-occurring AUD + mTBI + PTSD. This review article advances the knowledge base for rTMS as a treatment for AUD + mTBI + PTSD. This review provides background information about these co-occurring conditions as well as rTMS. The existing literature on rTMS as a treatment for people with AUD, TBI, and PTSD each alone is reviewed. Finally, neurobiological findings in support of a theoretical model are discussed to inform TMS as a treatment for co-occurring AUD + mTBI + PTSD. The peer-reviewed literature was identified by targeted literature searches using PubMed and supplemented by cross-referencing the bibliographies of relevant review articles. The existing evidence on rTMS as a treatment for these conditions in isolation, coupled with the overlapping neuropathology and symptomology of these conditions, suggests that rTMS may be well suited for the treatment of these conditions together.
