Background And Objectives: Anti-NMDAR encephalitis (NMDARE) is a severe neurologic condition, and recently, the NMDAR Encephalitis One-Year Functional Status (NEOS) score has emerged as a 1-year prognostic tool. This study aimed to evaluate NEOS score and biomarker (neurofilament light chains [NfL], total-Tau protein, glial fibrillary acidic protein, and serum cytokines) correlation with modified Rankin Scale (mRS), cognitive impairment, and clinical recovery in pediatric NMDARE over 2 years.

Methods: In this French multicenter observational study, 104 pediatric patients with NMDARE were followed for a minimum of 2 years.

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.

Article Synopsis
  • This study explored the recovery trajectories of Dizziness-Related Disability (DRD) in kids aged 8-17 who experienced concussions, using evaluations over 6 months.
  • Two main recovery groups were identified: a Low DRD group (79% of participants) and a High DRD group (21%).
  • Key factors predicting membership in the High DRD group included chronic neck pain, existing anxiety issues, and scores from a specific assessment tool (the 5P total score), highlighting the need for personalized treatment approaches.

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.

  • The study aimed to assess the burden experienced by Primary Family Caregivers (PFC) of children who suffered severe traumatic brain injuries, seven years after the incident.
  • Data was collected from 36 caregivers using various scales to measure subjective burden, health status, family functioning, and the child's needs, revealing that a significant percentage of caregivers reported varying degrees of burden.
  • Results indicated higher caregiver burden was linked to worse outcomes in child behavior and participation, highlighting the importance of addressing caregiver needs and providing ongoing psychological support.

Objectives: To perform a detailed description of executive functioning following moderate-to-severe childhood traumatic brain injury (TBI), and to study demographic and severity factors influencing outcome.

Methods: A convenience sample of children/adolescents aged 7-16 years, referred to a rehabilitation department after a TBI ( = 43), was compared to normative data using a newly developed neuropsychological test battery (Child Executive Functions Battery-CEF-B) and the BRIEF.

Results: Performance in the TBI group was significantly impaired in most of the CEF-B subtests, with moderate to large effect sizes.

This study aimed to investigate the impact of traumatic subarachnoid hemorrhage (tSAH) on cardiac autonomic control system (CACS) function in children after severe traumatic brain injury (TBI) during the subacute rehabilitation period. Thirty-three participants, 8-18 years of age, 42 (14-149) days after severe TBI at the beginning of the subacute rehabilitation, were included in the study. Six participants were diagnosed with tSAH during acute medical care (tSAH group).

The importance of measuring quality of survival within paediatric oncology trials is increasingly recognised. However, capturing neuropsychological outcomes and other aspects of quality of survival in the context of large or multinational trials can be challenging. We provide examples of protocols designed to address this challenge recently employed in clinical trials in the USA and Europe.

This study investigated parental reports of the level of care and needs 7-years following severe childhood traumatic brain injury (TBI), and the factors associated with this outcome. From the 65 children (0-15 years) consecutively admitted to the Parisian regional TBI reference intensive care unit following severe TBI, included in this prospective longitudinal study, 39 patients [M(SD) age at injury = 7.5 years (4.

Objective: To (1) determine the level of agreement between symptom provocation and performance-based tests of vestibulo-ocular reflex (VOR) function after pediatric mild traumatic brain injury (mTBI) and (2) describe the level of symptom provocation induced by a VOR task in individuals with and without cervical findings.

Design: Cross-sectional.

Setting: This study was conducted at a tertiary care pediatric hospital.

Left untreated, balance impairment following moderate-to-severe traumatic brain injury (TBI) can be highly debilitating and hinder activities of daily life. To detect impairments, clinicians need appropriate assessment tools. The objective of this study was to evaluate the feasibility and utility of a battery of clinical balance assessments in adults with moderate-to-severe TBI within 6-months of injury.

Objective: To assess the recovery of the cardiac autonomic control system (CACS) response to the modified tilt-test during rehabilitation, in children post moderate-severe TBI at the subacute phase post-injury.

Method: Thirty-seven children aged 6-18 years, 14-162 days post moderate-severe TBI, participated in the study. The assessment included CACS values evaluation (heart rate (HR), heart rate variability (HRV) and blood pressure) during the modified tilt-test: five minutes lying supine and five minutes passive standing.

Background: Impairments to oculomotor (OM) and vestibulo-ocular reflex (VOR) function following pediatric mTBI have been demonstrated but are poorly understood. Such impairments can be associated with more negative prognosis, affecting physical and mental wellbeing, emphasizing the need to more fully understand how these evolve.

Objectives: to determine i) the extent to which performance on clinical and computerized tests of OM and VOR function varies over time in children and adolescents at 21 days, 3-, and 6-months post-mTBI; ii) the proportion of children and adolescents with mTBI presenting with abnormal scores on these tests at each timepoint.

: There are few standardized measures available to assess executive function (EF) in a naturalistic setting for children. The Children's Cooking Task (CCT) is a complex test that has been specifically developed to assess EF in a standardized open-ended environment (cooking). The aim of the present study was to evaluate the internal consistency, inter-rater reliability, sensitivity and specificity, and also convergent and divergent validity of the Norwegian version of CCT among children with pediatric Acquired Brain Injury (pABI) and healthy controls (HCs).

Background: Childhood severe traumatic brain injury (TBI) is a leading cause of long-lasting acquired disability, but predicting long-term functional outcome remains difficult.

Objectives: This study aimed to 1) describe the functional outcome at 1 and 7 years post-TBI; 2) determine the initial and concurrent factors associated with long-term outcome; and 3) evaluate the predictive value of functional status, overall disability level and intellectual ability measured at 1 year post-injury to determine 7-year clinically meaningful outcomes.

Methods: Among the children (<16 years) consecutively included over 3 years in the Traumatisme Grave de l'Enfant (TGE) prospective longitudinal cohort study after accidental severe TBI, we studied the outcomes of 39 survivors at 1 and 7 years post-injury.
