“…Head trauma with <30 min loss of consciousness, 13 score on the Glasgow Coma Scale, and <24 h posttraumatic amnesiais is defined as mTBI. [14]. It accounts for 70 to 80 percent of TBI in the United States [15][16][17].…”

Abstract-Vergence dysfunction in individuals with mild traumatic brain injury (mTBI) may have a negative effect on quality of life, functional abilities, and rehabilitative progress. In this study, we used a range of dynamic and static objective and subjective measures of vergence to assess 21 adult patients with mTBI and nearwork symptoms. The results were compared with 10 control adult subjects. With respect to dynamic parameters, responses in those with mTBI were slowed, variable, and delayed. With respect to static parameters, reduced near point of convergence and restricted near vergence ranges were found in those with mTBI. The present results provide evidence for the substantial adverse effect of mTBI on vergence function.

“…Among 36,214 VHA electronic CTBIE records, we selected patients who did not report brain injury either predeployment or since returning from deployment (postdeployment) (n = 21,627). Of patients who were evaluated by a VA clinician as having experienced TBI, the sample was further restricted to those who met criteria for mTBI history based on VA-DOD clinical practice guidelines consistent with American Congress of Rehabilitation Medicine [44] criteria. mTBI history was determined by self-reports of alteration or loss of consciousness, posttraumatic amnesia, and these conditions' respective durations [45].…”

Abstract-With the use of Veterans Health Administration and Department of Defense databases of veterans who completed a Department of Veterans Affairs comprehensive traumatic brain injury (TBI) evaluation, the objectives of this study were to (1) identify the co-occurrence of self-reported auditory, visual, and vestibular impairment, referred to as multisensory impairment (MSI), and (2) examine demographic, deployment-related, and mental health characteristics that were potentially predictive of MSI. Our sample included 13,746 veterans with either a history of deployment-related mild TBI (mTBI) (n = 9,998) or no history of TBI (n = 3,748). The percentage of MSI across the sample was 13.9%, but was 17.4% in a subsample with mTBI history that experienced both nonblast and blast injuries. The factors that were significantly predictive of reporting MSI were older age, being female, lower rank, and etiology of injury. Deployment-related mTBI history, posttraumatic stress disorder, and depression were also significantly predictive of reporting MSI, with mTBI history the most robust after adjusting for these conditions. A better comprehension of impairments incurred by deployed servicemembers is needed to fully understand the spectrum of blast and nonblast dysfunction and may allow for more targeted interventions to be developed to address these issues.

“…The American Congress of Rehabilitation Medicine defines mTBI as a head trauma that produces (1) a loss of consciousness of 30 minutes or less, (2) any loss of memory immediately before or after the accident, (3) any alteration in mental state at the time of the accident, or (4) focal neurological deficit(s) [5]. Additional criteria include posttraumatic amnesia of less than 24 hours and a Glasgow Coma Scale score of 13 or higher 30 minutes postinjury.…”

Abstract-Mild traumatic brain injury (mTBI) is not uncommon among Operation Iraqi Freedom/Operation EnduringFreedom (OIF/OEF) veterans, and many individuals within this group report lingering cognitive difficulties following their injury. For Department of Veterans Affairs clinicians, an accurate assessment of cognitive symptoms is important in providing appropriate clinical care. Although self-assessment is commonly employed to screen for difficulties in cognitive functioning, little is known about the accuracy of self-report in this population. This study collected cognitive, psychiatric, and self-report data from 105 OIF/OEF veterans with mTBI to examine the relationship between self-reported cognitive functioning and objective neuropsychological test performance. Additionally, clinicians who frequently work with OIF/OEF veterans were asked to predict the magnitude of these associations. Self-reported cognitive functioning was not significantly correlated with objective cognitive abilities, suggesting that objective neuropsychological testing should be used when cognitive weakness is suspected. Perceived cognitive deficits were associated with depression, anxiety, and posttraumatic stress disorder, illustrating the additional importance of adequate assessment and treatment of psychiatric symptoms. Clinicians tended to overestimate the association between selfreport and test performance.
