Objective:
To examine relationships between history of mild traumatic brain injury (mTBI), neuropsychological measures of executive function, and lifetime history of criminal justice (CJ) involvement among combat-exposed Veterans and Service Members (V/SM).
Participants and Methods:Participants were combat-exposed V/SM who completed a baseline assessment for the multicenter Long-term Impact of Military-Relevant Brain Injury Consortium - Chronic Effects of Neurotrauma Consortium study (N=1,341) and had adequate engagement/symptom reporting on measures of performance and symptom validity (i.e., Medical Symptom Validity Test and Mild Brain Injury Atypical Symptoms Scale). Neuropsychological battery included the Trail Making Test (A and B), Wechsler Adult Intelligence Scale-IV (WAIS-IV) Digit Span subtest, and the National Institute of Health (NIH) Toolbox Flanker subtest. Lifetime history of brain injury, criminal justice involvement, and demographics were collected. Participants were 87% male, 72% white, with a mean age of 40 years (SD=9.67). Eighty-one percent had at least some college education. Nineteen percent were active duty. Eighty percent of Veterans and 86% of Service Members reported a history of >1 mTBI, and of these 31% and 47% respectively experienced 3+ mTBIs.
Results:Three groups were composed based on level of involvement with the CJ system: 1.) No history of arrests or incarcerations (3+ mTBIs: 64%), 2.) A lifetime history of arrest but no felony incarceration (3+ mTBIs: 34%), and 3.) A lifetime history of felony incarceration (3+ mTBIs: 2%). Ordinal regression analyses revealed that performance on a working memory task (Digit Span; b= 0.024, p= .041; OR= 1.024) was significantly associated with increased CJ involvement after adjusting for age, education, service status, and mTBIs. Performance on measures of processing speed (Trails A), set-shifting (Trails B), and inhibition (Flanker) were not significantly associated with CJ involvement. Number of mTBIs was significantly and positively associated with level of CJ involvement in all four models; Digit Span (p= .016), Trails A (p= .016), Trails B (p= .020), and Flanker (p= .008).
Conclusions:Performance on most measures of executive functioning was not significantly associated with CJ involvement in this large, representative sample of V/SM who served in combat. Although performance on a working memory task was significantly associated with CJ involvement, the size of the effect was small and the association was in the opposite direction as expected. Number of mTBIs was significantly associated with level of CJ involvement, indicating that sustaining multiple mTBI may be linked to greater risk of CJ involvement. These findings suggest that social and psychological factors beyond executive dysfunction may better explain the relationship between history mTBIs and CJ involvement. Some aspects of military service and veteran status, such as interdisciplinary treatment for brain injury and physical, mental, and psychosocial health needs, may be protective against previously identified risk factors for arrest (e.g., deficits in executive functioning). Contextualizing mTBI within the larger behavioral health profile of V/SM, with emphasis placed on intervention for related co-morbidities, may reduce the impact of previous arrest on wellbeing and/or reduce the risk of future CJ involvement.

Objective:
Olfaction is a critical sensory function and changes in the ability to detect smells could affect quality of life by diminishing appreciation of food, drink, and other aroma-based experiences, increase danger of hazardous exposures, and cause a loss of employment. Additionally, decrements in olfaction have been related to onset of some neurodegenerative conditions. Olfactory impairments in military populations are highly prevalent and often attributed to the long-term effects of mild traumatic brain injury (mTBI) and chronic psychiatric disorders. The main goal of this investigation was to examine olfactory function in a cohort of combat veterans using a quantitative smell test.
Participants and Methods:Participants underwent a neurological examination using a revised version of the Neurological Outcome Scale for Traumatic Brain Injury. Olfactory function was examined using a set of essential oil vials with common odors. Based on the number of correctly identified odors, the following grading system was employed: no deficit; mild; moderate; severe deficit; and absence of smell detection. All study assessments were performed prior to March of 2020 (onset of COVID-19 pandemic). In addition, participants completed performance validity testing (PVT) and screening for ongoing substance misuse using the Alcohol Use Disorders Identification Test and Drug Abuse Screening Test-10. Lifetime history of brain injury, combat-related extracranial injuries, and deployment characteristics were assessed using structured interview. All available medical records were reviewed.
Results:Participants were 38 veterans with a deployment-related mTBI who passed the PVT and did not have ongoing substance misuse issues. Olfactory examination revealed normosmia in 20 participants and various degrees of deficit in 18 (11= mild; 4=moderate; and 3=severe). The groups did not differ in demographics, post-injury interval, or current clinical (non-psychiatric) conditions. Participants with hyposmia frequently reported being exposed to a higher number of blasts and being positioned closer to the nearest primary blast, and more often endorsed a period of loss of consciousness after the most serious mTBI. In addition, they more often reported tympanic membrane perforation, extracranial injuries, and histories of both blast and blunt force mTBI. Comorbid diagnoses of posttraumatic stress disorder (PTSD), depression, chronic headaches, and pain were more common among these participants as well.
Conclusions:Several blast exposure and specific injury-related characteristics increase the likelihood of long-term olfactory impairments, comorbid psychiatric conditions, and chronic pain among veterans with a history of deployment-related mTBI. Notably, none of the participants with hyposmia had a clinical diagnosis of olfactory dysfunction or were receiving service-connected disability for a loss of sense of smell at the time of their assessment. Multidisciplinary rehabilitation care provided to combat veterans with history of mTBI and/or PTSD should include olfactory examination using both quantitative and qualitative smell tests, education regarding the adversities related to loss of smell, management of current psychiatric symptoms, and follow-up assessments. The lack of a comparison group without a history of mTBI and the small sample size were the main limitations of this investigation.

Harvey S. Levin obtained his Bachelor’s degree from City College of New York, in New York city, Ph.D. in Clinical Psychology from the University of Iowa, in Iowa City, completed his internships in Clinical Neuropsychology and Pediatric Psychology at the University of Iowa Hospitals in Iowa City and Clinical Psychology, Psychiatry and Pediatrics at the Illinois Masonic Medical Center in Chicago, and his fellowship in Neuropsychology at University of Iowa Hospitals in Iowa City.
Dr. Levin started his career in 1972 as Instructor with the Department of Psychology at the University of Iowa and transitioned to The University of Texas Medical Branch (UTMB) in Galveston, Texas, in 1974, where he began an internationally renowned career in clinical work, teaching, and, most of all, pioneering research on traumatic brain injury (TBI). He ultimately became the Chela and Jimmy Storm Distinguished Professor in Surgical Research, Division of Neurosurgery, Department of Surgery in 1987. After leaving Texas for two years to take a position with the University of Maryland Medical System and Shock Trauma Institute in Baltimore, he moved back to Houston Texas in 1995 and established the Cognitive Neuroscience Laboratory (CNL) within the Department of Physical Medicine & Rehabilitation at Baylor College of Medicine, which was supported by federal grants, including funding from the National Institutes of Health, Department of Defense, Department of Veterans Affairs, and Centers for Disease Control and Prevention, and numerous private foundations. The CNL integrated rehabilitation and neuroplasticity research with multimodality brain imaging, clinical and neuropsychological assessment, and fluid biomarkers. Dr. Levin was Professor with the Departments of Physical Medicine and Rehabilitation where he served as Director of Research (1995-2014), Pediatrics, and Neurosurgery at Baylor College of Medicine. He was also a Research Scientist and the Director of the Center of Excellence for Traumatic Brain Injury at the Michael E. DeBakey Veterans Affairs Medical Center (2008-2013), and Adjunct Professor with the Department of Psychology at Rice University in Houston, Texas.
Dr. Levin’s research focused on investigating both acute and long-term outcomes of mild to severe TBI in civilian and military populations, including cognitive and behavioral sequelae in relation to neuropathology using advanced brain imaging modalities. He began prospective, longitudinal studies of adults and children who had sustained TBI associated with closed head trauma upon joining UTMB and developed, in collaboration with Drs O’Donnell and Grossman, the Galveston Orientation and Amnesia Test (GOAT). The GOAT was the first measure to assess post-traumatic amnesia and orientation following moderate to severe TBI, is still most widely used by the clinicians and researchers, and it has been translated to 16 languages. The original publication, “Levin HS, O’Donnell VM, Grossman RG. The Galveston Orientation and Amnesia Test. A practical scale to assess cognition after head injury. J Nerv Ment Dis. 1979 Nov;167(11):675-84. doi: 10.1097/00005053-197911000-00004. PMID: 501342”, has over 1200 citations. This work continued with participation in the NINDS Traumatic Coma Data Bank and the organization of outcome assessments for NINDS-funded clinical trials of hypothermia to treat severe TBI. To monitor the quality of outcome data across performing sites, Dr. Levin and colleagues developed a code for the reliability of data collected and implemented the role of an outcome monitor who evaluated adherence to protocol across sites. Following establishment of the CNL, he pursued investigation of TBI outcomes across the lifespan using multimodality brain imaging and biomarkers, errorless learning, translational studies in collaboration with neuroscientists using animal models, and clinical trials of methylphenidate, progesterone, CDP-choline. Dr. Levin spent over 30 years researching neurobehavioral outcomes of head injury in children, starting with a small pilot study funded by the Shriners Hospital in 1991 and continuing with several cycles of a multicenter R01 grant funded by the National Institute of Health. In later years, he used his expertise as a member of several large consortiums, including the Long-term Impact of Military-Relevant Brain Injury Consortium \ Chronic Effects of Neurotrauma Consortium (LIMBIC-CENC) funded by the VA and DoD and the Transforming Research and Clinical Knowledge in Traumatic Brain Injury (TRACK-TBI) funded by the NINDS.
During his career, Dr. Levin authored and coauthored more than 400 articles in scientific journals and over 100 books, with one of them, “Levin, H. S., Benton, A. L., & Grossman, R. G. (1982). Neurobehavioral consequences of closed head injury. Oxford University Press, USA”, having over 1100 citation, as well as book chapters that advanced knowledge of TBI, epilepsy, neurodegenerative diseases, and other illnesses that affect brain functioning. He was also very active as a reviewer on federal grant panels and as an editor and reviewer for the Journal of Neurotrauma, Journal of Clinical and Experimental Neuropsychology, Archives of Physical Medicine & Rehabilitation, Neuropsychology, Journal of the International Neuropsychological Society, Lancet, JAMA, Pediatrics, and other top-cited journals. He served as president of the International Neuropsychological Society in 1989-1990. Dr. Levin was a recipient of numerous prestigious awards, including the Javits Neuroscience Investigator Award, the Jennett-Plum Award for Research on Traumatic Brain Injury, the Distinguished Career Award by the International Neuropsychological Society, the American Congress of Rehabilitation Gold Key Award, the Distinguished Lifetime Contribution to Neuropsychology Award from the National Academy of Neuropsychology, as well as awards from other head injury and psychological organizations, including the International Brain Injury Association, the National Head Injury Foundation, the North American Brain Injury Society, Texas Psychological Association, and the Defense and Veterans Brain Injury Center. In addition to his stellar scientific accomplishments, Dr. Levin trained, mentored, and provided supervision to interns, fellows, postdocs, residents, medical and psychology students. He was the Director of an NCMRR/NIH T32 Postdoctoral Research Program, and training supervisor in neuropsychology for Baylor College of Medicine and for the Memorial Hermann TIRR Neuropsychology Postdoctoral Fellowship Programs. A passionate educator, he taught classes at Baylor College of Medicine, the University of Houston, and the National and Kapodistrian University of Athens Medical School in Greece and served as an evaluator for the American Board of Clinical Neuropsychology/American Board of Professional Psychology. He was often invited as a lecturer at numerous scientific organizations.
The main objective of this symposium is to provide an overview of the current state of research in TBI while highlighting Dr. Levin’s contributions to this field. The symposium will start with a brief overview of Dr. Levin’s career (Dr. Randall S. Scheibel), followed by presentations focused on the assessment of adult TBI, including posttraumatic amnesia (Dr. Felicia C. Goldstein), the current state of pediatric TBI (Dr. L. Ewing-Cobbs), and novel imaging in TBI (Dr. Erin D. Bigler). There will be a brief discussion session at the end lead by Dr. Elisabeth A. Wilde.

Objectives: Blast explosions are the most frequent mechanism of traumatic brain injury (TBI) in recent wars, but little is known about their long-term effects. Methods: Functional connectivity (FC) was measured in 17 veterans an average of 5.46 years after their most serious blast related TBI, and in 15 demographically similar veterans without TBI or blast exposure. Subcortical FC was measured in bilateral caudate, putamen, and globus pallidus. The default mode and fronto-parietal networks were also investigated. Results: In subcortical regions, between-groups t tests revealed altered FC from the right putamen and right globus pallidus. However, following analysis of covariance (ANCOVA) with age, depression (Center for Epidemiologic Studies Depression Scale), and posttraumatic stress disorder symptom (PTSD Checklist – Civilian version) measures, significant findings remained only for the right globus pallidus with anticorrelation in bilateral temporal occipital fusiform cortex, occipital fusiform gyrus, lingual gyrus, and cerebellum, as well as the right occipital pole. No group differences were found for the default mode network. Although reduced FC was found in the fronto-parietal network in the TBI group, between-group differences were nonsignificant after the ANCOVA. Conclusions: FC of the globus pallidus is altered years after exposure to blast related TBI. Future studies are necessary to explore the trajectory of changes in FC in subcortical regions after blast TBI, the effects of isolated versus repetitive blast-related TBI, and the relation to long-term outcomes in veterans.

Explosive blast is a frequent cause of traumatic brain injury (TBI) among personnel deployed to Afghanistan and Iraq. Functional magnetic resonance imaging (fMRI) with an event-related stimulus-response compatibility task was used to compare 15 subjects with mild, chronic blast-related TBI with 15 subjects who had not experienced a TBI or blast exposure during deployment. Six TBI subjects reported multiple injuries. Relative to the control group, TBI subjects had slightly slower responses during fMRI and increased somatic complaints and symptoms of post-traumatic stress disorder (PTSD) and depression. A between-group analysis indicated greater activation during stimulus-response incompatibility in TBI subjects within the anterior cingulate gyrus, medial frontal cortex, and posterior cerebral areas involved in visual and visual-spatial functions. This activation pattern was more extensive after statistically controlling for reaction time and symptoms of PTSD and depression. There was also a negative relationship between symptoms of PTSD and activation within posterior brain regions. These results provide evidence for increased task-related activation following mild, blast-related TBI and additional changes associated with emotional symptoms. Limitations of this study include no matching for combat exposure and different recruitment strategies so that the control group was largely a community-based sample, while many TBI subjects were seeking services.
