As Time Goes by: Understanding Child and Family Factors Shaping Behavioral Outcomes After Traumatic Brain Injury

Behaviour outcomes three months after mild TBI in preschool children

This study examined parents' report of behaviour in preschoolers after a mild traumatic brain injury (mTBI), compared the proportion of preschoolers with elevated behaviour ratings between the mTBI and limb injury (LI) groups, and explored injury, premorbid child, and parent variables that may be associated with parents' report of behaviour at three months post-injury. Children aged 2-5 years with a mTBI (n = 13) or mild LI (n = 6) were recruited from the emergency department. Behaviour was assessed using the Child Behaviour Checklist. Preliminary findings showed that post-injury behaviour ratings remained in the normal range. The mTBI group had higher scores than the LI group at three months post-injury in terms of sleep; however, this may have been pre-existing. Two children with mTBI received borderline-clinically significant ratings on diagnostic-level anxiety problems at the three-month follow-up, while none of the limb-injured controls obtained elevated behaviour ratings. Parent-rated post-injury behaviour was significantly associated with premorbid child functioning and parental stress, which needs to be explored in greater detail using larger preschool mTBI samples.

Neurorehabilitation across the Continuum: From the Neurocritical care unit to home

Children admitted to neurocritical care units often experience new neurodevelopmental disabilities due to both their acquired neurologic injuries and deconditioning from prolonged hospitalizations. Rehabilitation for critically ill children is multifactorial and begins in the intensive care unit itself. The goals of rehabilitation include prevention of complications associated with immobilization and evolving tone, comprehensive evaluation and treatment of functional deficits, and implementation of adaptive strategies with the goal of maximizing recovery. As a child progresses along the medical continuum from the neurocritical care unit to acute care to post-hospitalization settings, their rehabilitative needs and interventions should also evolve. A child in the neurocritical care unit is likely to have sustained an acquired brain injury. Whether resulting from traumatic or non-traumatic causes, all etiologies of pediatric acquired brain injury can result in significant challenges for the child and their family. Post-intensive care syndrome-pediatrics is a clinical construct that that systematically organizes the range of physical, cognitive, psychological, and social symptoms that emerge in both a child and their family members following a critical illness. Ideally, outpatient care for this population evaluates and supports all areas of post-intensive care syndrome-pediatrics through an interdisciplinary clinical care model. Proactive and comprehensive rehabilitation across the continuum provides the opportunity to support the child and their family in all areas affected, thereby minimizing distress, maximizing function, and optimizing outcomes.

Executive functioning, behavior, and white matter microstructure in the chronic phase after pediatric mild traumatic brain injury: results from the adolescent brain cognitive development study

BACKGROUND

Mild traumatic brain injury (mTBI) is common in children. Long-term cognitive and behavioral outcomes as well as underlying structural brain alterations following pediatric mTBI have yet to be determined. In addition, the effect of age-at-injury on long-term outcomes is largely unknown.

METHODS

Children with a history of mTBI (n = 406; Mage = 10 years, SDage = 0.63 years) who participated in the Adolescent Brain Cognitive Development (ABCD) study were matched (1:2 ratio) with typically developing children (TDC; n = 812) and orthopedic injury (OI) controls (n = 812). Task-based executive functioning, parent-rated executive functioning and emotion-regulation, and self-reported impulsivity were assessed cross-sectionally. Regression models were used to examine the effect of mTBI on these domains. The effect of age-at-injury was assessed by comparing children with their first mTBI at either 0-3, 4-7, or 8-10 years to the respective matched TDC controls. Fractional anisotropy (FA) and mean diffusivity (MD), both MRI-based measures of white matter microstructure, were compared between children with mTBI and controls.

RESULTS

Children with a history of mTBI displayed higher parent-rated executive dysfunction, higher impulsivity, and poorer self-regulation compared to both control groups. At closer investigation, these differences to TDC were only present in one respective age-at-injury group. No alterations were found in task-based executive functioning or white matter microstructure.

CONCLUSIONS

Findings suggest that everyday executive function, impulsivity, and emotion-regulation are affected years after pediatric mTBI. Outcomes were specific to the age at which the injury occurred, suggesting that functioning is differently affected by pediatric mTBI during vulnerable periods. Groups did not differ in white matter microstructure.

Long-term Participation and Functional Status in Children Who Experience Traumatic Brain Injury

OBJECTIVE

To evaluate the effect of child and family factors on children's participation outcomes 2 to 3 years following traumatic brain injury (TBI).

SETTING

Two level 1 pediatric trauma centers.

PARTICIPANTS

Children aged 0 to 15 years with TBI at all severity levels or an orthopedic injury.

DESIGN

Prospective cohort.

MAIN MEASURES

Caregivers completed the Child and Adolescent Scale of Participation (CASP) at 2- and 3-year follow-ups. The CASP was categorized as more than 90 or 90 or less on a 100-point scale, with 90 or less representing the 10th percentile and below in this sample. Modified Poisson regression models were used to describe relative risk of the CASP at 90 or less at 2 to 3 years postinjury, adjusting for preinjury family environment variables and injury group. A secondary analysis only included children who were 31 months or older at injury (n = 441) to determine whether changes in functional outcome (Pediatric Injury Functional Outcome Scale, PIFOS) and executive functions (Behavior Rating Inventory of Executive Function, BRIEF) from preinjury to 1 year after injury predicted CASP scores at the 2- or 3-year follow-up.

RESULTS

Seventy-eight percent (596/769) of children who had a completed preinjury survey had a completed CASP. In the adjusted model, children with severe TBI had a nearly 3 times higher risk (RR = 2.90; 95% CI, 1.43-5.87) of reduced participation than children with an orthopedic injury. In the secondary analysis, lower functional skills (5-point increase in 1-year postinjury PIFOS score) (RR = 1.36; 95% CI, 1.18-1.57) and less favorable family function (RR = 1.46; 95% CI, 1.02-2.10) were associated with reduced participation in both girls and boys.

CONCLUSION

Participation in home, school, and community activities after TBI is related to multiple biopsychosocial factors. Participation-focused interventions are needed to reduce barriers to involvement and assist children and families to close the participation gap across settings.

A Multidimensional Approach to Assessing Factors Impacting Health-Related Quality of Life after Pediatric Traumatic Brain Injury

In the field of pediatric traumatic brain injury (TBI), relationships between pre-injury and injury-related characteristics and post-TBI outcomes (functional recovery, post-concussion depression, anxiety) and their impact on disease-specific health-related quality of life (HRQoL) are under-investigated. Here, a multidimensional conceptual model was tested using a structural equation model (SEM). The final SEM evaluates the associations between these four latent variables. We retrospectively investigated 152 children (8-12 years) and 148 adolescents (13-17 years) after TBI at the recruiting clinics or online. The final SEM displayed a fair goodness-of-fit (SRMR = 0.09, RMSEA = 0.08 with 90% CI [0.068, 0.085], GFI = 0.87, CFI = 0.83), explaining 39% of the variance across the four latent variables and 45% of the variance in HRQoL in particular. The relationships between pre-injury and post-injury outcomes and between post-injury outcomes and TBI-specific HRQoL were moderately strong. Especially, pre-injury characteristics (children's age, sensory, cognitive, or physical impairments, neurological and chronic diseases, and parental education) may aggravate post-injury outcomes, which in turn may influence TBI-specific HRQoL negatively. Thus, the SEM comprises potential risk factors for developing negative post-injury outcomes, impacting TBI-specific HRQoL. Our findings may assist healthcare providers and parents in the management, therapy, rehabilitation, and care of pediatric individuals after TBI.

History of pediatric TBI hospitalization and current child-parent relationship quality in China

BACKGROUND

Long-term child-parent relationship quality following hospitalization for pediatric traumatic brain injury (TBI) remains poorly understood.

OBJECTIVE

We tested whether current child-parent conflict and closeness were related to the children's history of TBI-related experiences and contemporary child/family characteristics.

METHODS

The sample included 202 Chinese children (Boys: 60.4%) with a history of hospitalization for TBI. On average, the children were 11.2 years old (SD = 1.59) and sustained TBI at 8.5 years old (SD = 1.6). TBI-related data were obtained from hospital medical records. Parents provided data on child-parent closeness, child-parent conflict, and parental efficacy 2-4 years (M = 2.7, SD = 0.7) after discharge.

RESULTS

Forty-nine children (24.3%) had mild TBI, 139 (68.8%) had moderate TBI, and 14 (6.9%) had severe TBI. Surgical intervention occurred among 128 (63.4%) of the 202 children. Contemporaneous child and family characteristics explained 19% of the variance, history of surgery, length of hospitalization, and recovery status explained another 7%, and the interaction between length of hospitalization and parental efficacy explained another 4% in child-parent conflict. Contemporaneous child and family characteristics explained 29% of the variance, and TBI-related variables explained another 2% in child-parent closeness.

CONCLUSION

Post-TBI child-parent relationship was more associated with child/family characteristics than with TBI variables. Practitioners and families should be aware of the long-term challenges to child-parent relationship following hospitalization for pediatric TBI.

Exploring the measurement of pediatric cognitive-communication disorders in traumatic brain injury research: A scoping review

OBJECTIVE

To synthesize information about the constructs measured, measurement instruments used, and the timing of assessment of cognitive-communication disorders (CCDs) in pediatric traumatic brain injury (TBI) research.

METHODS AND PROCEDURES

Scoping review conducted in alignment with Arksey and O'Malley's five-stage methodological framework and reported per the PRISMA extension for Scoping Reviews. Inclusion criteria: (a) cohort description, case-control, and treatment studies; (b) participants with TBI aged 5-18 years; (c) communication or psychosocial outcomes; and (d) English full-text journal articles. The first author reviewed all titles, abstracts, and full-text articles; 10% were independently reviewed.

OUTCOMES AND RESULTS

Following screening, a total of 687 articles were included and 919 measurement instruments, measuring 2134 unique constructs, were extracted. The Child Behavior Checklist was the most used measurement instrument and 'Global Outcomes/Recovery' was the construct most frequently measured. The length of longitudinal monitoring ranged between ≤3 months and 16 years.

CONCLUSIONS AND IMPLICATIONS

We found considerable heterogeneity in the constructs measured, the measurement instruments used, and the timing of CCD assessment in pediatric TBI research. A consistent approach to measurement may support clinical decision-making and the efficient use of data beyond individual studies in systematic reviews and meta-analyses.

Mood Disorders in Young People With Acquired Brain Injury: An Integrated Model

Purpose/Objective

Young people with paediatric acquired brain injury (pABI) are twice as likely to develop a mood disorder as their peers, frequently have significant unmet socio-emotional needs, and are at over double the risk of going on to use adult mental health services. Recent years have seen significant advances in the development of interventions for young people with mood disorders. However, evidence-based approaches to mood disorders in pABI are lacking and surprisingly little work has evaluated clinical and neuro-developmental models of mood disorders in this population.

Method

We review the literature regarding key mechanisms hypothesised to account for the increased vulnerability to mood disorders in pABI: First, we summarise the direct neurocognitive consequences of pABI, considering the key areas of the brain implicated in vulnerability to mood disorders within a neurodevelopmental framework. Second, we outline five key factors that contribute to the heightened prevalence of mood disorders in young people following ABI. Finally, we synthesise these, integrating neuro-cognitive, developmental and systemic factors to guide clinical formulation.

Results and Implications

We present a framework that synthesises the key mechanisms identified in our review, namely the direct effects of pABI, neurocognitive and neuroendocrine factors implicated in mood and anxiety disorders, maladaptive neuroplasticity and trauma, structural and systemic factors, and psychological adjustment and developmental context. This framework is the first attempt to provide integrated guidance on the multiple factors that contribute to elevated life-long risk of mood disorders following pABI.
