Neurological outcome in children and youth with acquired brain injury 2-year post-injury

Exploring caregiver and participant experiences of the Program for the Education and Enrichment of Relational Skills (PEERS®) for youth with acquired brain injury and cerebral palsy

PURPOSE

This study explored the experience of adolescents with brain injuries and their caregivers who participated in the Program for the Education and Enrichment of Relational Skills (PEERS®) in Australia.

MATERIALS AND METHODS

Twenty-seven adolescents and 31 caregivers, who completed the PEERS® intervention as part of an RCT, contributed to focus groups following the 14-week program. Semi-structed interviews guided focus groups. An interpretive description methodology was used to understand participants' experiences in the program and suggestions for improvements.

RESULTS

Thematic analysis led to the development of five themes. "Challenging families and meeting expectations" explored the challenge and worth of participating. "Learnt new skills" highlighted skills and strategies gained and methods used to achieve these. "Connecting, belonging and understanding that's our normal" represented the value placed on the group experience. "Confidence in knowing and doing" reflected the changes in everyday social experiences and "Where to from here?" provided many suggestions for adaptation to improve practice.

CONCLUSION

After taking part in the PEERS® social skills group intervention, most adolescents with brain injury and their caregivers perceived improvement in their social participation and had suggestions for improving the group experience. Some adolescents didn't enjoy the program.IMPLICATIONS FOR REHABILITATIONOffering adolescents with brain injury and their caregivers the opportunity to participate in a group social skills intervention is an important part of paediatric rehabilitation.Participants of group social skills interventions are likely to perceive improvements in their everyday social functioning following completion.Considering strategies to enhance engagement in the group is expected to be important for outcomes.Participants of group social skills programs may need additional support and adjustments to balance the demands of the intervention with other everyday family and school tasks and requirements.

Intelligence and executive function are associated with age at insult, time post-insult, and disability following chronic pediatric acquired brain injury

Background

Pediatric acquired brain injury (pABI) profoundly affects cognitive functions, encompassing IQ and executive functions (EFs). Particularly, young age at insult may lead to persistent and debilitating deficits, affecting daily-life functioning negatively. This study delves into the intricate interplay of age at insult, time post-insult, and their associations with IQ and EFs during chronic (>1 year) pABI. Additionally, we investigate cognitive performance across different levels of global function, recognizing the multifaceted nature of developmental factors influencing outcomes.

Methods

Drawing upon insult data and baseline information analyzing secondary outcomes from a multicenter RCT, including comprehensive medical and neuropsychological assessments of participants aged 10 to 17 years with pABI and parent-reported executive dysfunctions. The study examined associations between age at insult (early, EI; ≤7y vs. late, LI; > 7y) and time post-insult with IQ and EFs (updating, shifting, inhibition, and executive attention). Additionally, utilizing the Pediatric Glasgow Outcome Scale-Extended, we explored cognitive performance across levels of global functioning.

Results

Seventy-six participants, median 8 years at insult and 5 years post-insult, predominantly exhibiting moderate disability (n = 38), were included. Notably, participants with LI demonstrated superior IQ, executive attention, and shifting compared to EI, [adjusted mean differences with 95% Confidence Intervals (CIs); 7.9 (1.4, 14.4), 2.48 (0.71, 4.24) and 1.73 (0.03, 3.43), respectively]. Conversely, extended post-insult duration was associated with diminished performances, evident in mean differences with 95% CIs for IQ, updating, shifting, and executive attention compared to 1-2 years post-insult [-11.1 (-20.4, -1.7), -8.4 (-16.7, -0.1), -2.6 (-4.4, -0.7), -2.9 (-4.5, -1.2), -3.8 (-6.4, -1.3), -2.6 (-5.0, -0.3), and -3.2 (-5.7, -0.8)]. Global function exhibited a robust relationship with IQ and EFs.

Conclusion

Early insults and prolonged post-insult durations impose lasting tribulations in chronic pABI. While confirmation through larger studies is needed, these findings carry clinical implications, underscoring the importance of vigilance regarding early insults. Moreover, they dispel the notion that children fully recover from pABI; instead, they advocate equitable rehabilitation offerings for pABI, tailored to address cognitive functions, recognizing their pivotal role in achieving independence and participation in society. Incorporating disability screening in long-term follow-up assessments may prove beneficial.

Fatigue in young patients with acquired brain injury in the outpatient rehabilitation setting: A 2-year follow-up study

Acquired brain injury (ABI) may cause fatigue and participation restrictions in young patients. However, knowledge regarding the course of these problems over time is lacking. This study aims to describe the course of fatigue and participation and their relationship over time in an observational two-year follow-up study among patients(5-24 years) with ABI referred for outpatient rehabilitation and their parents. Patients/parents completed the PedsQL™Multidimensional-Fatigue-Scale(PedsQL™MFS, totalscore/3-domains) and the Child/Adolescent-Scale of Participation(CASP, totalscore/4-domains). Scores ranged from 0-100: lower scores = more fatigue/participation problems. Linear mixed models and repeated measures correlations were used to determine the course over time (change-scores/95%CI) and correlations between fatigue/participation. At baseline, 223 patients/246 parents participated with 94/104 at either T1, T2 or both. Median age was 15 years (IQR:12-17), 74% had a traumatic brain injury. Mean(SD) patient/parent-reported PedsQL™MFS totalscores(baseline) were: 50.3(17.3) and 53.8(19.1), respectively. CASP totalscores were 78.0(16.4) and 87.1(13.6). Over time, patient-reported scores improved significantly (fatigue: + 8.8 (2.9;14.7), p < 0.05)/participation: + 10.5 (6.3;14.7), p < 0.05)). Similar results were found regarding parent-reported fatigue: + 8.7 (3.4;13.9), p < 0.05 but not regarding participation. Two years later, fatigue was still considerable(patients:59.1/parents:62.5). Moderate/fair correlations between fatigue/participation over time were found. Fatigue and participation in young patients with ABI improved two years after referral to rehabilitation. However, fatigue remained a considerable problem.

Post-PICU sleep efficiency and quality of life in infants and toddlers with acquired brain injury

STUDY OBJECTIVES

We aimed to investigate the use of sleep efficiency (SE) as a measure of sleep disturbance in infants and toddlers with acquired brain injury (ABI) and evaluate associations between SE and child health-related quality of life and family outcomes.

METHODS

Retrospective cohort study of 101 children ages 3-36 months who survived critical care for ABI. SE was quantified from the Brief Infant Sleep Questionnaire as a ratio of nighttime sleep to total time in bed; poor SE was defined as < 80%. Outcome measures included the Pediatric Quality of Life Inventory Core Total Score (health-related quality of life) and Family Impact Module Total Score. Spearman's correlation quantified associations between SE and outcomes. Multivariable linear regression tested association between poor SE and health-related quality of life controlling for significant covariates (age, diagnosis, comorbidities, worsening Functional Status Scale).

RESULTS

Following ABI, median SE was 91.7 (interquartile range = 83.3, 95.5). Nineteen (19%) children had poor SE (< 80%). SE correlated significantly with quality of life (Spearman's correlation = .307) and Family Impact Module (Spearman's correlation = .309; both P < .01). When controlling for covariates, poor SE significantly increased risk for lower health-related quality of life (β-coefficient = -7.0; 95% confidence interval= -13.4, -0.6).

CONCLUSIONS

One in five infants and young children with ABI have poor SE that is associated with poorer child and family health outcomes. Our study underscores the potential importance of sleep following ABI to optimize recovery and the need for additional investigation of SE in infants and young children.

Sleep disturbances in infants and young children following an acquired brain injury

STUDY OBJECTIVES

Sleep disturbances impact over half of older children and teens with acquired brain injury (ABI) following critical care hospitalization but are underevaluated in infants and young children. Given the importance of sleep in brain development and healing after injury, we hypothesized sleep disturbances would be associated with worse neurodevelopmental outcomes in infants with ABI.

METHODS

We performed a retrospective cohort study of 68 children aged 2-32 months following critical care hospitalization for ABI. The Brief Infant Sleep Questionnaire assessed sleep disturbances. Bayley Scales of Infant and Toddler Development, third edition and Adaptive Behavior Assessment System, third edition assessed developmental and adaptive functioning outcomes, respectively. t tests compared sleep characteristics in infants with ABI to historical healthy controls. Spearman's correlation evaluated relationships among sleep and outcomes. Multiple linear regression investigated relationships controlling for demographic and ABI characteristics.

RESULTS

Compared to healthy controls, children with ABI had shorter nighttime sleep duration (P = .01), longer daytime sleep duration (P < .001), and longer duration of nighttime awakenings (P < .001). Duration of night awakenings negatively correlated with Bayley Cognitive scores (Spearman's correlation = -.40). Night awakenings negatively correlated with worse Adaptive Behavior Assessment System, third edition General Adaptive Composite scores (Spearman's correlation = -.42). When controlling for demographic and ABI characteristics, ≥ 3 awakenings was significantly associated with worse Adaptive Behavior Assessment System, third edition General Adaptive Composite (β = -11.3; 95% confidence interval = -19.2, -3.5).

CONCLUSIONS

Sleep disturbances are associated with poorer outcomes in infants and toddlers after ABI. Sleep is vital to recovery and a potentially modifiable target to improve outcomes.

Parent-reported family impact in children and young adults with acquired brain injury in the outpatient rehabilitation setting

Purpose: To increase knowledge/awareness on family impact (FI) after acquired brain injury (ABI) in rehabilitation settings, it is essential to investigate the associations between patient-functioning and impact on families. This has been explored in hospital-based cohorts, but not in rehabilitation settings.Methods: A cross-sectional, multi-center study among parents of children/young adults (aged 5-24 years) with ABI referred to rehabilitation was performed. Patient/injury/family-characteristics were noted, and parents completed the PedsQL™Family-Impact-Module and PedsQL™generic-core-4.0 to assess FI and health-related quality of life (HRQoL). Univariate- and multivariable-regression analyses were performed to investigate associations between HRQoL/patient/injury/family-related factors and FI.Results: 246 families participated; patients' median age was 14 year (IQR 11-16), 65 had non-traumatic-brain-injury (nTBI) (26%), 127 were female. FI was found to be considerable (median FIM-score 71.9, IQR:60-85). Especially referral to rehabilitation >6 months after onset, diminished patients' mental/emotional health and HRQoL (child/family factors), and premorbid problems were associated with higher FI.Conclusions: In this rehabilitation cohort, pediatric ABI caused considerably higher FI than in hospital-based studies with referral to rehabilitation >6 months, diminished child/family factors and presence of premorbid problems increasing FI. Assessing and monitoring FI and its associated factors enables professionals to individualize treatment, psychoeducation, support and follow-up.

Determinants of impairments in functioning, fatigue, and participation ability in pediatric brain tumor survivors

Background

Pediatric brain tumor survivors (PBTS) experience disease- and treatment-related sequelae. We aimed to investigate the occurrence of participation limitations, impairments in functioning, fatigue, and the association between patient, tumor- and treatment-related factors and these outcomes.

Methods

Children (4–18 years) after treatment for a brain tumor between 2005 and 2014 at the Erasmus Medical Center, Rotterdam, the Netherlands, were eligible. The parent-reported Child and Family Follow-up Survey developed to measure participation and impairments in functioning in youth with acquired brain injury, was used. Fatigue was assessed using the Pediatric Quality of Life Inventory Multidimensional Fatigue Scale. Associations with patient, tumor- and treatment-related factors were explored using univariable analyses.

Results

Ninety-one PBTS (median age: 11.3 years [range: 9.5–14.1], time since treatment: 3.9 years [range: 4–6.2]) were included (response rate: 55%). Participation limitations were reported in 53% and were associated with impairments in functioning (15–67%) (P ≤ .01) and fatigue (P ≤ .03).

Parent- and child-reported fatigue was increased compared to normative values (P ≤ .02). History of hydrocephalus was associated with increased fatigue (P ≤ .04). Younger age at diagnosis and longer time since diagnosis were associated with impairments in functioning and cognitive fatigue (P &lt; .05).

Participation limitations, impairments in functioning and fatigue were similar in PBTS who were &lt;3 or ≥3 years since completion of treatment.

Conclusion

More than half of PBTS reported limited participation ability, which is associated with impairments in functioning and fatigue. The complication hydrocephalus seems to lead to more fatigue. Participation limitations, impairments in functioning and fatigue appear not to diminish in the longer term.

Pediatric traumatic brain injury and abusive head trauma

Childhood traumatic brain injury (TBI) commonly occurs during brain development and can have direct, immediately observable neurologic, cognitive, and behavioral consequences. However, it can also disrupt subsequent brain development, and long-term outcomes are a combination of preinjury development and abilities, consequences of brain injury, as well as delayed impaired development of skills that were immature at the time of injury. There is a growing number of studies on mild TBI/sport-related concussions, describing initial symptoms and their evolution over time and providing guidelines for effective management of symptoms and return to activity/school/sports. Mild TBI usually does not lead to long-term cognitive or academic consequences, despite reports of behavioral/psychologic issues postinjury. Regarding moderate to severe TBI, injury to the brain is more severe, with evidence of a number of detrimental consequences in various domains. Patients can display neurologic impairments (e.g., motor deficits, signs of cerebellar disorder, posttraumatic epilepsy), medical problems (e.g., endocrine pituitary deficits, sleep-wake abnormalities), or sensory deficits (e.g., visual, olfactory deficits). The most commonly reported deficits are in the cognitive-behavioral field, which tend to be significantly disabling in the long-term, impacting the development of autonomy, socialization and academic achievement, participation, quality of life, and later, independence and ability to enter the workforce (e.g., intellectual deficits, slow processing speed, attention, memory, executive functions deficits, impulsivity, intolerance to frustration). A number of factors influence outcomes following pediatric TBI, including preinjury stage of development and abilities, brain injury severity, age at injury (with younger age at injury most often associated with worse outcomes), and a number of family/environment factors (e.g., parental education and occupation, family functioning, parenting style, warmth and responsiveness, access to rehabilitation and care). Interventions should identify and target these specific factors, given their major role in postinjury outcomes. Abusive head trauma (AHT) occurs in very young children (most often <6 months) and is a form of severe TBI, usually associated with delay before appropriate care is sought. Outcomes are systematically worse following AHT than following accidental TBI, even when controlling for age at injury and injury severity. Children with moderate to severe TBI and AHT usually require specific, coordinated, multidisciplinary, and long-term rehabilitation interventions and school adaptations, until transition to adult services. Interventions should be patient- and family-centered, focusing on specific goals, comprising education about TBI, and promoting optimal parenting, communication, and collaborative problem-solving.

Describing the Composition of Individualized Education Plans for Students With Traumatic Brain Injury

Purpose The purpose of this study was to explore and describe the features of Individualized Education Plans (IEPs) for a cohort of students with traumatic brain injury (TBI) to help elucidate current special education practices for students with TBI. Method We obtained permission from administrators of a local school district of 41,000 students in a Midwestern state to review de-identified IEP records of students verified with TBI. We examined demographic information (i.e., cause and age at time of injury), IEP services and intensity, IEP goal categories, and previous verification status. Results Descriptive results support that intervention services were more intense for students with TBI with greater lengths of time postinjury. Target behaviors within goals were more often related to math and reading than to the cognitive processes that govern these skills, such as attention, memory, and executive functioning. Finally, more than a third of our sample had been verified with a disability and were receiving special education services via an IEP prior to their TBI. Conclusions This work represents an important first step in understanding the special education services for students with TBI. Future research should explore interventions that are ecologically valid for school-based settings and are developed to address the idiosyncratic deficits of students with TBI, particularly interventions that focus on the underlying cognitive processes experienced by these students.

Paediatric traumatic brain injury

PURPOSE OF REVIEW

To provide a summary of recent developments in the field of paediatric traumatic brain injury (TBI).

RECENT FINDINGS

The epidemiology of paediatric TBI with falling rates of severe TBI, and increasing presentations of apparently minor TBI. There is growing interest in the pathophysiology and outcomes of concussion in children, and detection of 'significant' injury, arising from concern about risks of long-term chronic traumatic encephalopathy. The role of decompressive craniectomy in children is still clarifying.

SUMMARY

Paediatric TBI remains a major public health issue.

Microstructural abnormalities in deep and superficial white matter in youths with mild traumatic brain injury

BACKGROUND

Diffusion Tensor Imaging (DTI) studies of traumatic brain injury (TBI) have focused on alterations in microstructural features of deep white matter fibers (DWM), though post-mortem studies have demonstrated that injured axons are often observed at the gray-white matter interface where superficial white matter fibers (SWM) mediate local connectivity.

OBJECTIVES

To examine microstructural alterations in SWM and DWM in youths with a history of mild TBI and examine the relationship between white matter alterations and attention.

METHODS

Using DTIDWM fractional anisotropy (FA) and SWM FA in youths with mild TBI (TBI, n=63) were compared to typically developing and psychopathology matched control groups (n=63 each). Following tract-based spatial statistics, SWM FA was assessed by applying a probabilistic tractography derived SWM mask, and DWM FA was captured with a white matter fiber tract mask. Voxel-wise z-score calculations were used to derive a count of voxels with abnormally high and low FA for each participant. Analyses examined DWM and SWM FA differences between TBI and control groups, the relationship between attention and DWM and SWM FA and the relative susceptibility of SWM compared to DWM FA to alterations associated with mild TBI.

RESULTS

Case-based comparisons revealed more voxels with low FA and fewer voxels with high FA in SWM in youths with mild TBI compared to both control groups. Equivalent comparisons in DWM revealed a similar pattern of results, however, no group differences for low FA in DWM were found between mild TBI and the control group with matched psychopathology. Slower processing speed on the attention task was correlated with the number of voxels with low FA in SWM in youths with mild TBI.

CONCLUSIONS

Within a sample of youths with a history of mild TBI, this study identified abnormalities in SWM microstructure associated with processing speed. The majority of DTI studies of TBI have focused on long-range DWM fiber tracts, often overlooking the SWM fiber type.
