Donders J, Ramos A. Correlates of performance on the Child and Adolescent Memory Profile (ChAMP) in a mixed pediatric sample. Child Neuropsychol 2024:1-12. [PMID: 38817122 DOI: 10.1080/09297049.2024.2361123] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2024] [Accepted: 05/21/2024] [Indexed: 06/01/2024]
Abstract
This study aimed to determine some of the factors that influence performance on a comprehensive test of verbal and visual memory in children, the Child and Adolescent Memory Profile (ChAMP) in a mixed clinical sample (n = 178; 56% male, 67% White, median age 12 years). We used hierarchical linear regression analyses with ChAMP standard scores as the dependent variable, and parental education as well as Wechsler Intelligence Scale for Children-Fifth Edition (WISC-V) factor index scores as the independent variables. WISC-V Processing Speed and (to a lesser extent) Working Memory were statistically significant predictors of most ChAMP Index scores. In addition, WISC-V Verbal Comprehension contributed to the model for ChAMP Verbal Memory, and WISC-V Visual Spatial to the model for ChAMP Visual Memory. In each case better performance on the WISC-V was predictive of higher scores on the ChAMP, with large effect sizes. WISC-V variables also mediated the positive effect of parental education on ChAMP scores. We conclude that clinicians should consider performance on measures of speed of processing, working memory, language and visual-spatial skills as potential influences on ChAMP results that may suggest a specific memory deficit.

Abstract
BACKGROUND Urea cycle disorders (UCDs) cause impaired conversion of waste nitrogen to urea leading to rise in glutamine and ammonia. Elevated ammonia and glutamine have been implicated in brain injury. This study assessed relationships between biomarkers of metabolic control and long-term changes in neuropsychological test scores in participants of the longitudinal study of UCDs. The hypothesis was that elevated ammonia and glutamine are associated with neuropsychological impairment. METHODS Data from 146 participants who completed 2 neuropsychological assessments were analyzed. Neuropsychological tests that showed significant changes in scores over time were identified and associations between score change and interim metabolic biomarker levels were investigated. RESULTS Participants showed a significant decrease in performance on visual motor integration (VMI) and verbal learning immediate-recall. A decrease in scores was associated with experiencing interim hyperammonemic events (HAE) and frequency of HAE. Outside of HAE there was a significant association between median ammonia levels ≥50µmol/L and impaired VMI. CONCLUSION VMI and memory encoding are specifically affected in UCDs longitudinally, indicating that patients experience difficulties when required to integrate motor and visual functions and learn new information. Only ammonia biomarkers showed a significant association with impairment. Preventing HAE and controlling ammonia levels is key in UCD management. IMPACT The Beery-Buktenica Developmental Test of Visual-Motor Integration (Beery VMI) and List A Trial 5 of the California Verbal Learning Test (CVLT) may be good longitudinal biomarkers of treatment outcome in urea cycle disorders (UCD). This is the first report of longitudinal biomarkers for treatment outcome in UCD. These two biomarkers of outcome may be useful for clinical trials assessing new treatments for UCD. These results will also inform educators how to design interventions directed at improving learning in individuals with UCDs.

Abstract
Traumatic brain injury (TBI) is a serious public health concern impacting millions of children and adolescents each year. Experiencing a brain injury during key critical periods of brain development can affect the normal formation of brain networks that are responsible for a range of complex neurocognitive outcomes. In addition, there are multiple pre- and postinjury factors that influence the trajectory of recovery and outcomes. In this review, we will focus on the current state of the literature within pediatric TBI; systematically review the available research on developmental aspects of TBI in children, focusing on the pathophysiology of the injury and its impact on the developing brain; and highlight knowledge gaps for further exploration.

Abstract
This study aimed to clarify the value of using different types of validity measures in pediatric neuropsychological evaluations. We examined the relationship between performance (PVT) and symptom (SVT) validity tests as well as demographic variables and results from a screening test of learning and memory (i.e. Child and Adolescent Memory Profile [ChAMP]) in a mixed pediatric sample (n = 103). There was minimal overlap between PVT and SVT failures. Regression analyses demonstrated that PVT results, parental education, and history of special education were statistically significant predictors of ChAMP results, whereas SVT results were not.

Abstract
OBJECTIVE To explore memory functioning 7 years after severe paediatric traumatic brain injury (TBI), associated factors, and relationships with other outcomes. METHOD Children aged 0-15 years (n = 65), consecutively admitted over a 3-year period in a single trauma centre, who survived after severe non-inflicted TBI, were included in a prospective longitudinal study. Memory assessments were performed 7 years post-injury using the Children's Memory Scale or the Wechsler Memory Scale (WMS IV), according to age. The General Memory Score (GMS-7) was the primary outcome. RESULTS Thirty-seven patients were available for assessment at 7 years post-injury. Mean GMS-7 was in the low average range (M = 84.9, SD = 12.1). Lower GMS-7 was significantly associated with markers of higher injury severity, such as length of coma. One year post-injury functional and disability outcomes explained 74% of the variance of GMS-7. Concurrent intellectual ability and type of ongoing education correlated strongly with GMS-7. Age at injury and parental education were not associated with memory outcome. CONCLUSIONS Memory functioning is variable but often strongly impaired several years after severe paediatric TBI, and is mostly related to injury severity, functional outcomes measured 1 year post-injury, and concomitant cognitive and educational outcomes. GMS-7 was lower at 7 years than one year post-injury, supporting the importance of long term follow-up.

Abstract
Sixty-one children and adolescents with traumatic brain injury completed the Child and Adolescent Memory Profile (ChAMP; Sherman & Brooks, 2015) within 1 to 12 months post injury. Most of the ChAMP index scores demonstrated statistically significant negative correlations with time to follow commands following traumatic brain injury. Compared with demographically matched neurologically healthy controls, selected from the ChAMP standardization sample, participants with traumatic brain injury had statistically significantly lower scores on all ChAMP index scores but sensitivity and specificity were suboptimal. We conclude that the ChAMP has modest clinical utility as part of a more comprehensive evaluation of sequelae of traumatic brain injury in children and adolescents.
