AbstractLiterature suggests that individuals with mild traumatic brain injury (mTBI) show subtle abnormalities in the cognitive control process of performance monitoring. The neural bases of performance monitoring can be measured using the error-related negaitivity (ERN) and post-error positivity (Pe) components of the scalp-recorded event-related potential (ERP). Thirty-six individuals with mTBI and 46 demographically similar controls completed a modified color-naming Stroop task while ERPs were recorded. Separate repeated-measures analyses of variance were used to examine the behavioral (response times [RT] and error rates) and ERP (ERN and Pe amplitudes) indices of performance monitoring. Both groups showed slower RTs and increased error rates on incongruent trials relative to congruent trials. Likewise, both groups showed more negative ERN and more positive Pe amplitude to error trials relative to correct trials. Notably, there were no significant main effects or interactions of group for behavioral and ERP measures. Subgroup and correlational analyses with post-concussive symptoms and indices of injury severity were also not significant. Findings suggest comparable performance to non-injured individuals in some aspects of cognitive control in this sample. Neuropsychological implications and comparison with other cognitive control component processes in individuals with TBI are provided. (JINS, 2012, 18, 323–333)

Abstract Objective Research literature has demonstrated the role that pre-morbid anxiety has in prolonging recovery from mild traumatic brain injury (mTBI). The aim of this investigation is to clarify the degree of the relationship between anxiety and postconcussive symptomology in patients with mTBI. Method This study compared scores from a patient-report measure of anxiety, the General Anxiety Disorder-7 (GAD-7), to scores from a patient-report measure of postconcussion symptom severity, the Neurobehavioral Symptom Inventory (NSI). Participants were recruited from September 2018 to December 2019 who had been referred for clinical evaluation to Rehabilitation Institute of Washington’s Brain Injury Services (a privately-run, interdisciplinary, outpatient clinic). 39 adult participants (30 males and nine females) completed both the GAD-7 and NSI. No control group was used. Injury severity level was ascertained via review of the medical records. Patients underwent an abbreviated evaluation with a clinical neuropsychologist. As a part of this initial evaluation, patients completed an intake packet, which included the NSI and GAD-7. Results The relationship between the ordinal variables (i.e., anxiety and postconscussive symptomology) was assessed using spearman’s rho. Anxiety had a strong, statistically significant relationship with postconcussive symptomology (rho = 0.670, p = 0.000). Conclusions Anxiety and postconcussive symptomology severity are associated in this population of patients with mTBI. Limitations of this current investigation include a small sample size and no control group. This study indicates the need for controlled studies in future research to address the above-encountered limitations. Nevertheless, this study lends support to the prevalence of anxiety in those with elevated postconcussive symptomology and the need to monitor this in assessment and treatment.

Post Concussion Syndrome

Post-Concussion Syndrome (PCS) is a relatively prevalent condition that emerges after sustaining a head injury. Individuals with PCS experience prolonged impairments and distress associated with the injury which can impact the individuals’ quality of life experiences. In this retrospective chart review of refractory adult patients diagnosed with PCS and mild Traumatic Brain Injury (mTBI), the effectiveness of Cortical Integrative Therapy (PedroCIT®) was investigated by comparing measures of postural stability, brain sequencing and timing, and self-reports of physical and psychosocial symptoms of PCS obtained before and after PedroCIT®. Multivariate and Repeated Measures General Linear Models showed improvements across the measures from before to after treatment in all subjects, highlighting the effectiveness of PedroCIT®. To further underscore the capacity of PedroCIT® to elicit improvements in patients who have been resistant to treatment prior to PedroCIT®, the duration of time that the subjects underwent PedroCIT® was compared to the duration of time since the injury to the subjects’ first PedroCIT® intervention session. The findings of this study showed significant improvements from pre- to post-treatment in postural stability, brain sequencing and timing, and self-reported symptoms for patients affected by PCS and mTBI, and treatment outcomes were largely not contingent upon the severity of the condition at the beginning of treatment. Altogether, this retrospective study suggests that refractory individuals affected by PCS and mTBI can benefit from undergoing PedroCIT® and their treatment outcomes may not be related to the degree of impairment presented at the beginning of treatment.

AbstractObjectives: Research on the cognitive sequelae of mild traumatic brain injury (mTBI) suggests that, despite generally rapid recovery, difficulties may persist in the domain of cognitive control. The goal of this study was to examine whether individuals with chronic blast-related mTBI show behavioral or neural alterations associated with cognitive control. Methods: We collected event-related functional magnetic resonance imaging (fMRI) data during a flanker task in 17 individuals with blast-related mTBI and 16 individuals with blast-exposure without TBI (control). Results: Groups did not significantly differ in behavioral measures of cognitive control. Relative to the control group, the mTBI group showed greater deactivation of regions associated with the default mode network during the processing of errors. Additionally, error processing in the mTBI group was associated with enhanced negative coupling between the default mode network and the dorsal anterior cingulate cortex as well as the dorsolateral prefrontal cortex, regions of the salience and central executive networks that are associated with cognitive control. Conclusions: These results suggest that deactivation of default mode network regions and associated enhancements of connectivity with cognitive control regions may act as a compensatory mechanism for successful cognitive control task performance in mTBI.
