Traumatic Brain Injury (TBI) is defined by changes in brain function resulting from external forces acting on the brain and is typically characterized by a host of physiological and functional changes such as cognitive deficits including attention problems. In the present study, we focused on the effect of TBI on the ability to allocate attention in vision (i.e., the use of endogenous and exogenous visual cues) by systematically reviewing previous literature on the topic. We conducted quantitative synthesis of 16 selected studies of visual attention following TBI, calculating 80 effect size estimates. The combined effect size was large (g = 0.79, p < 0.0001) with medium heterogeneity (I2 = 68.39%). Subgroup analyses revealed an increase in deficit with moderate-to-severe and severe TBI as compared to mild TBI [F(2, 76) = 24.14, p < 0.0001]. Task type was another key source of variability and subgroup analyses indicated that higher order attention processes were severely affected by TBI [F(2, 77) = 5.66, p = 0.0051). Meta-regression analyses revealed significant improvement in visual attention deficit with time [p(mild) = 0.031, p(moderate-to-severe) = 0.002, p(severe) < 0.0001]. Taken together, these results demonstrate that visual attention is affected by TBI and that regular assessment of visual attention, using a systematic attention allocation task, may provide a useful clinical measure of cognitive impairment and change after TBI.

Abstract Background Service members with a history of mild traumatic brain injury (mTBI) frequently report problems paying attention. In combat and training settings, visual attention is critical given the demand to warfighter performance. Many computerized cognitive rehabilitation programs exist, however the impact of their effectiveness on improving visual attention is unknown. Methods A randomized controlled trial consisted of 22 active-duty service members with a history of mTBI. Participants were randomized to Lumosity (N = 8) which focused on multiple cognitive domains or UCR which has a specific focus on visual attention (N = 14). Cognitive assessment was completed at baseline and following treatment. The Neuropsychological Assessment Battery (NAB) Driving Scenes subtest was used as the primary assessment of visual attention. All participants passed a validity measure pre and post assessment. Results A one-way ANOVA revealed that performance on NAB Driving Scenes improved for all participants after treatment (F = 4.18, p = 0.046); however, when computer program type was analyzed there was no interaction (F = 0.32, p = 0.860). Participants who completed the UCR intervention improved from M = 41.64, SD = 11.58 to M = 46.79, SD = 14.52, Cohen’s d = 0.43. For the Lumosity condition, there was a medium effect size (Cohen’s d = 0.46) from baseline (M = 38.63, SD = 14.33) to post treatment (M = 44.75, SD = 9.47) Conclusions The results indicated that both programs proved effective at improving visual attention symptoms. These findings provide support for the use of computerized cognitive rehabilitation programs as a form of intervention for mTBI.

Purpose The purpose of this investigation was to measure the effect of message type (i.e., action, naming) on the visual attention patterns of individuals with and without traumatic brain injury (TBI) when viewing grids composed of 3 types of images (i.e., icons, decontextualized photographs, and contextualized photographs). Method Fourteen adults with TBI and 14 without TBI—assigned either to an action or naming message condition—viewed grids composed of 3 different image types. Participants' task was to select/sustain visual fixation on the image they felt best represented a stated message (i.e., action or naming). Results With final fixation location serving as a proxy for selection, participants in the naming message condition selected decontextualized photographs significantly more often than the other 2 image types. Participants in the action message condition selected contextualized photographs significantly more frequently than the other 2 image types. Minimal differences were noted between participant groups. Conclusions This investigation provides preliminary evidence of the relationship between image and message type. Clinicians involved in the selection of images used for message representation should consider the message being represented when designing supports for people with TBI. Further research is necessary to fully understand the relationship between images and message type.
