Objective: This study aimed to identify Dizziness-Related Disability (DRD) recovery trajectories in pediatric concussion and assess clinical predictors of disability groups. Materials and Methods: In this prospective cohort study, 81 children (8–17 years) diagnosed with an acute concussion took part in 3 evaluation sessions (baseline, 3-month, and 6-month). All sessions included the primary disability outcome, the Dizziness Handicap Inventory (DHI) to create the DRD recovery trajectories using group-based multi-trajectory modeling analysis. Each independent variable included general patients' characteristics, premorbid conditions, function and symptoms questionnaires, and clinical physical measures; and were compared between the trajectories with logistic regression models. Results: Low DRD (LD) trajectory (n = 64, 79%), and a High DRD (HD) trajectory (n = 17, 21%) were identified. The Predicting and Preventing Postconcussive Problems in Pediatrics (5P) total score (Odds Ratio (OR):1.50, 95% Confidence Interval (CI): 1.01–2.22), self-reported neck pain (OR:7.25, 95%CI: 1.24–42.36), and premorbid anxiety (OR:7.25, 95%CI: 1.24–42.36) were the strongest predictors of belonging to HD group. Conclusions: Neck pain, premorbid anxiety, and the 5P score should be considered initially in clinical practice as to predict DRD at 3 and 6-month. Further research is needed to refine predictions and enhance personalized treatment strategies for pediatric concussion. [ABSTRACT FROM AUTHOR]

Introduction: Severe pediatric traumatic brain injury (spTBI), including abusive head trauma (AHT) in young children, is a major public health problem. Long-term consequences of spTBI include a large variety of physical, neurological, biological, cognitive, behavioral and social deficits and impairments Areas covered: The present narrative review summarizes studies and reviews published from January 2019 to February 2024 on spTBI. Significant papers published before 2019 were also included. The article gives coverage to the causes of spTBI, its epidemiology and fatality rates; disparities, inequalities, and socioeconomic factors; critical care; outcomes; and interventions. Expert opinion: There are disparities between countries and according to socio-economic factors regarding causes, treatments and outcomes of spTBI. AHT has an overall poor outcome. Adherence to critical care guidelines is imperfect and the evidence-base of guidelines needs further investigations. Neuroimaging and biomarker predictors of outcomes is a rapidly evolving domain. Long-term cognitive, behavioral and psychosocial difficulties are the most prevalent and disabling. Their investigation should make a clear distinction between objective (clinical examination, cognitive tests, facts) and subjective measures (estimations using patient- and proxy-reported questionnaires), considering possible common source bias in reported difficulties. Family/caregiver-focused interventions, ecological approaches, and use of technology in delivery of interventions are recommended to improve long-term difficulties after spTBI.

Introduction: Early focal brain injuries lead to long-term disabilities with frequent cognitive impairments, suggesting global dysfunction beyond the lesion. While plasticity of the immature brain promotes better learning, outcome variability across individuals is multifactorial. Males are more vulnerable to early injuries and neurodevelopmental disorders than females, but long-term sex differences in brain growth after an early focal lesion have not been described yet. With this MRI longitudinal morphometry study of brain development after a Neonatal Arterial Ischemic Stroke (NAIS), we searched for differences between males and females in the trajectories of ipsi- and contralesional gray matter growth in childhood and adolescence, while accounting for lesion characteristics. Methods: We relied on a longitudinal cohort (AVCnn) of patients with unilateral NAIS who underwent clinical and MRI assessments at ages 7 and 16 were compared to age-matched controls. Non-lesioned volumes of gray matter (hemispheres, lobes, regions, deep structures, cerebellum) were extracted from segmented T1 MRI images at 7 (Patients: 23 M, 16 F; Controls: 17 M, 18 F) and 16 (Patients: 18 M, 11 F; Controls: 16 M, 15 F). These volumes were analyzed using a Linear Mixed Model accounting for age, sex, and lesion characteristics. Results: Whole hemisphere volumes were reduced at both ages in patients compared to controls (gray matter volume: -16% in males, -10% in females). In ipsilesional hemisphere, cortical gray matter and thalamic volume losses (average -13%) mostly depended on lesion severity, suggesting diaschisis, with minimal effect of patient sex. In the contralesional hemisphere however, we consistently found sex differences in gray matter volumes, as only male volumes were smaller than inmale controls (average-7.5%), mostly in territoriesmirroring the contralateral lesion. Females did not significantly deviate from the typical trajectories of female controls. Similar sex differences were found in both cerebellar hemispheres. Discussion: These results suggest sex-dependent growth trajectories after an early brain lesion with a contralesional growth deficit in males only. The similarity of patterns at ages 7 and 16 suggests that puberty has little effect on these trajectories, and that most of the deviation in males occurs in early childhood, in line with the well-described perinatal vulnerability of themale brain, and with no compensation thereafter.

Importance: Care partners' involvement is a key feature of the Cognitive Orientation to daily Occupational Performance (CO-OP) approach that can enhance rehabilitation outcomes and promote the generalization and transfer of strategies and skills to everyday life. Gaining insight into care partners' experience with their child's CO-OP intervention is critical to understanding how to enhance care partners' involvement. Objective: To gain insight into the experience of care partners whose child with acquired brain injury (ABI) participated in CO-OP intervention. Method: A qualitative descriptive research design was used. Semistructured interviews were conducted at three time points (immediate postintervention and at 2 and 6 mo postintervention). Setting: Two rehabilitation centers. Participants: Thirteen care partners of 12 children or youth with severe ABI. Results: Three themes emerged from the analysis of 33 interviews: (1) The child is an active agent in their therapy, (2) the care partner is the keystone who helps solidify the elements of CO-OP, and (3) CO-OP mastery requires time and practice, and its use evolves over time. Conclusions and Relevance: These themes highlight the progressive nature of proficiency in CO-OP for both care partners and children. This was evident not only in the children's improvement in task performance, but also in their ability to problem solve. Care partners' role in supporting the CO-OP approach also unfolds over time as their confidence in their child's problem-solving abilities, and in their own ability to adequately provide guidance, increases. Engagement seems to be central in facilitating this progression for both children and their care partners. Plain-Language Summary: This is the first study to provide insights into the involvement of care partners in the Cognitive Orientation to daily Occupational Performance (CO-OP) approach for children and youth with executive function deficits after acquired brain injury. This is also the first study to explore the evolution of care partners' experiences over time. Involving care partners is a key feature of the CO-OP. Understanding care partners' experiences with their child's CO-OP intervention can improve a child's rehabilitation outcomes. The study found that care partners' role in supporting their child's CO-OP approach improved over time as their confidence in their child's problem-solving abilities increased. The care partners' own ability to adequately provide guidance to their child also increased over time. Engagement seems to be central in facilitating this progression for both children and their care partners. It is hoped that occupational therapists will consider the findings of this study to better support care partners in implementing the CO-OP approach with their child in their real-life context. Care partners' role in supporting their child's engagement with the Cognitive Orientation to daily Occupational Performance (CO-OP) occupational therapy approach improved over time as their confidence in their child's problem-solving abilities increased.

Aim: To determine the effectiveness of the Cognitive Orientation to daily Occupational Performance (CO‐OP) approach in improving the occupational performance goals of children and young people with executive function deficits after acquired brain injury (ABI) (e.g. etiologies such as stroke, encephalitis, brain tumor, and traumatic brain injury). Method: A replicated single‐case experimental study using a randomized multiple baseline design across participants and goals was used. Three clusters of four participants (12 participants, nine males and three females, aged 8–16 years) were included. The intervention consisted of 14 individual CO‐OP sessions. Each participant chose four goals; three goals were trained during the intervention sessions and a fourth goal served as the control. The Goal Attainment Scale (GAS) was used as a repeated measure to determine goal achievement while the Canadian Occupational Performance Measure (COPM) was used to identify the perceived goal achievement of children, young people, and their parents. Results: For 26 of the 35 trained goals, the intervention led to statistically significant improvements in the GAS. Perceived occupational performance and satisfaction improved significantly for the trained goals (30 out of 35 goals for the COPM performance and satisfaction of participants; 26 out 31 goals for the COPM performance of parents; 24 out of 31 goals for the COPM satisfaction of parents) and were maintained at the follow‐up. Almost all COPM control goal results were significant, but these changes were not supported by the GAS measures or the statistical analysis. Interpretation: The generally positive results of this study provide evidence of the benefits of using the CO‐OP approach with this population. [ABSTRACT FROM AUTHOR]
