AbstractMild traumatic brain injury (mTBI), or concussion, accounts for 85% of all TBIs. Yet survivors anticipate full cognitive recovery within several months of injury, if not sooner, dependent upon the specific outcome/measure. Recovery is variable and deficits in executive function, e.g., working memory (WM) can persist years post-mTBI. We tested whether cognitive deficits persist in otherwise healthy undergraduates, as a conservative indicator for mTBI survivors at large. We collected WM performance (change detection, n-back tasks) using various stimuli (shapes, locations, letters; aurally presented numbers and letters), and wide-ranging cognitive assessments (e.g., RBANS). We replicated the observation of a general visual WM deficit, with preserved auditory WM. Surprisingly, visual WM deficits were equivalent in participants with a history of mTBI (mean 4.3 years post-injury) and in undergraduates with recent sports-related mTBI (mean 17 days post-injury). In seeking the underlying mechanism of these behavioral deficits, we collected resting state fMRI (rsfMRI) and EEG (rsEEG). RsfMRI revealed significantly reduced connectivity within WM-relevant networks (default mode, central executive, dorsal attention, salience), whereas rsEEG identified no differences (modularity, global efficiency, local efficiency). In summary, otherwise healthy current undergraduates with a history of mTBI present behavioral deficits with evidence of persistent disconnection long after full recovery is expected.

Abstract Objective Examine factors associated with history of arrests and felony incarceration among Veterans and Service Members (V/SM) with combat exposure. Method Participants were V/SM who completed a baseline assessment for the multicenter Chronic Effects of Neurotrauma Consortium study (N = 1555). Most were male (87%), white (72%), with a mean age of 40 years (SD = 9.71). The majority (83%) reported a history of ≥1 mild traumatic brain injury (mTBI), with thirty-five present of those experiencing 3+ mTBIs. Results Three groups were composed based on self-reported level of involvement with the criminal justice system: 1.) No history of arrests or incarcerations (65%), 2.) A lifetime history of arrest but no felony incarceration (32%), and 3.) A lifetime history of felony incarceration (3%). Chi-square and Kruskal-Wallis H tests revealed statistically significant differences between the groups in demographic factors including the incarcerated group having younger age, greater percentage of men, lower education, and greater percentage of never being married, followed by the arrest group and then the no arrest group (all p < 0.05). The incarcerated group also had the highest level of posttraumatic stress disorder (PTSD) symptoms, lowest social support, and greatest percentage of hazardous alcohol consumption, followed by the arrest and then the no arrest groups (all p < 0.05). No differences were found between groups for mTBI history or neuropsychological testing results. Conclusions Correlates of legal involvement among V/SM span demographic and psychological dimensions. Some correlates are modifiable, including social support, PTSD symptoms, and alcohol consumption. Addressing these modifiable risk factors is critical to lower the risk of future criminal justice involvement.
