2022, Doctor of Philosophy, Case Western Reserve University, Communication Sciences.
Purpose: Cognitive fatigue is one of the most persistent and disabling symptoms after acquired brain injury, but few studies have investigated cognitive fatigue after childhood traumatic brain injury (TBI) using functional tasks or pairing objective and subjective measures. The overall purpose of this study was to compare cognitive fatigue during and across functional tasks in children with TBI and children who were typically developing (TD) using objective and subjective measures. Methods: The primary aim was addressed through the completion of an online set of surveys after daily activities. A subset of participants also completed eye tracking tasks to obtain objective data. Survey participants (N = 30) included 15 children with TBI and 15 TD children who were 8-14 years old. Participants with TBI were an average of 4.69 years old at the time of their injury and 5.37 years post-injury at the time of study participation. A subset of seven of these participants (TBI n =2; TD n =5) participated in the eye tracking portion of the study. Results: Participants in the TBI group were rated to have significantly greater levels of cognitive fatigue, compared to TD participants, on subjective measures. Yet, daily activities evoked similar levels of cognitive fatigue for both groups. Greater levels of cognitive fatigue were significantly associated with lower quality of life for both groups. One significant difference was found in percent change of mean pupil diameter during eye tracking tasks, such that the reading task evoked greater levels of subconscious cognitive fatigue compared to all other tasks. Subjective and objective measures of cognitive fatigue were not significantly associated after eye tracking tasks. Conclusion: The findings of this study support the chronic nature of cognitive fatigue after childhood TBI, its interactions with other areas of functioning, and opportunities to refine survey and experimental design to support the understanding of cognitive fatigue to improve supports, services, and outcomes for individuals with childhood TBI.
