An iPad-based intervention to improve visual-motor, visual-attention, and visual-perceptual skills in children with surgically treated hydrocephalus: A pilot study.

PURPOSE: Develop and pilot an iPad-based intervention for improving visual-motor coordination, visual-spatial processing/reasoning, and visual attention in children with surgically treated hydrocephalus (HCP). METHODS: We developed an intervention protocol targeting visual-motor coordination, visual-spatial processing/reasoning, and visual attention. Fourteen participants with HCP completed 30 h of training over 6 weeks. The primary outcome measure was the Perceptual Reasoning Index from the Wechsler Abbreviated Scale of Intelligence, Second Edition. Secondary measures included subtests from the Wechsler Intelligence Scale for Children, Fourth Edition, Developmental NEuroPSYchological Assessment, Second Edition (NEPSY-II), and Purdue Pegboard. RESULTS: Children with HCP demonstrated gains with statistical significance on the Perceptual Reasoning Index. We also observed significant improvement on a timed test of visuo-motor coordination (Wechsler Intelligence Scale for Children, Fourth Edition, Coding). CONCLUSION: Our iPad-application-based intervention may promote visual-motor coordination, visual-spatial processing/reasoning, and visual attention skills in children with HCP, offering an engaging and economical supplement to more conventional therapies.

[Formula: see text] The role of family burden on informant discrepancies between parents and youths with protracted recovery from mild traumatic brain injury.

Previous literature shows that family burden can lead to symptom-report discrepancies between parents and children. The present study sought to extend this research by investigating the influence of family burden factors, including socioeconomic status (SES) and family stress on informant discrepancies between parents and youths with mild traumatic brain injury (mTBI). Participants were clinically referred youths with mTBI ages 8-17, consecutively seen in a hospital-based neuropsychology concussion clinic (N = 81; females = 54.3%). Parents and children completed the Behavioral Assessment for Children System (BASC) and the Postconcussive Symptom Scale (PCSS). Parents rated changes in family stress related to the mTBI (categorized as "no change," "minor change," or "major change") and provided information to calculate SES. Results revealed that family stress but not SES influenced parent-child report discrepancies for the BASC Internalizing Symptoms Index (F = 8.72(2, 79), p <.000), and that the discrepancies were independent of postconcussive symptom severity. Clinical implications of these findings are discussed.

Noncredible effort on the Nonverbal-Medical Symptom Validity Test (NV-MSVT): Impact on cognitive performance in pediatric mild traumatic brain injury.

This study examined failure rates on the Nonverbal-Medical Symptom Validity Test (NV-MSVT) and its impact on cognitive performance in a sample of youths with mild traumatic brain injury (mTBI). Participants were 184 children and adolescents who presented to a multidisciplinary concussion clinic for a targeted neuropsychological evaluation. Performance Validity Tests (PVTs) were a part of the standard battery, including the NV-MSVT. Twenty-eight participants (15.2%) failed the NV-MSVT, none of whom displayed a genuine memory impairment profile (GMIP). Participants who failed the NV-MSVT performed significantly worse than those who passed the NV-MSVT on measures of IQ, memory, and immediate attention/working memory. There was no significant difference between groups on processing speed, sustained attention, cognitive flexibility, or sight word reading level. Aside from a slight difference in age, NV-MSVT failure was not impacted by demographic variables (sex, race), premorbid risk factors (pre-injury ADHD, learning disabilities, psychiatric diagnoses or treatment, developmental delays, or prior special education), injury-related variables (time since injury, positive neuroimaging findings, post-traumatic amnesia, number of prior mTBIs, etc.) or post-mTBI anxiety/depression. That said, participants who failed NV-MSVT endorsed significantly more severe postconcussive symptoms. These findings support the use of the NV-MSVT in neuropsychological evaluation of children and adolescents with mTBI.

Sensitivity of the Memory Validity Profile (MVP): Raising the bar.

The Memory Validity Profile (MVP) is a performance validity test (PVT) designed specifically for pediatric populations and utilizes specific cut-points for identifying noncredible performance at different ages. This study aims to evaluate the MVP using a known-groups design to determine optimal cut-off scores for detecting noncredible performance in youths with mild traumatic brain injury (mTBI) across different age-groups. Participants were 114 youths (age 5-17) with mTBI who were referred for neuropsychological evaluation in a hospital-based concussion clinic. All participants were administered the Nonverbal-Medical Symptom Validity Test (NV-MSVT) and the MVP. Participants who failed the NV-MSVT were also administered the TOMM. Participants who failed both the NV-MSVT and the TOMM comprised the criterion group (i.e., the "Failed two PVTs" group). Participants who failed only one PVT were excluded from the analysis. ROC curve analyses revealed good discriminability (AUC = .844: 95%, CI = 676-1.0, p = .001) with acceptable sensitivity (.73) and specificity (.91) for an optimal MVP Total score cut-off ≤31. There were no differences in MVP Total scores across age-groups. In conclusion, adopting stricter cut-points for non-credible performance and applying these consistently across all age groups in a mTBI population increases the clinical utility of the MVP.

Bridging gaps in care for children with acquired brain injury: Perceptions of medical and educational service providers.

PURPOSE: Significant gaps in service delivery for children with acquired brain injury exist between healthcare and educational systems, such as the lack of coordinated efforts to transfer rehabilitation strategies to school settings. This paper attempts to address these issues and offer recommendations to bridge these gaps in care. METHODS: The American Congress of Rehabilitation Medicine (ACRM), Brain Injury-Interdisciplinary Special Interest Group (BI-ISIG), Pediatric-Adolescent Task Force constructed and disseminated a survey to medical rehabilitation (N= 44) and education professionals (N= 40). Responses were analyzed quantitatively and qualitatively, achieving > 85% inter-coder reliability. RESULTS: Results highlighted differences between groups in methods for seeking new information, opinions on advocacy needs, and differing priorities given to various resources. CONCLUSIONS: These discrepancies have important implications for improved collaboration needed for assuring an appropriate continuum of service for this population. Recommendations include: 1) providing education and training regarding brain injury in the most cost-effective ways utilizing technology that crosses the barriers identified and reaches people in multiple settings; 2) direct and active communication between medical and educational professionals; and 3) developing an interdisciplinary Community of Practice to help bridge medical rehabilitation and school systems.

Optimizing Neurocritical Care Follow-Up Through the Integration of Neuropsychology.

BACKGROUND: Pediatric critical care survivors often suffer persisting multisystem health problems and are left with treatment needs that go unmet due to limits in current care models. We proposed that integration of neuropsychology into neurocritical care follow-up provides incremental benefit to the identification and treatment of persisting complications and reduction in co-morbidities. BASIC PROCEDURES: The aims of this study were three-fold. First, we described pilot programs at two pediatric hospitals as models for implementing systematic follow-up care with interdisciplinary clinic teams consisting of critical care, neurology, and neuropsychology. Second, we described working models specific to neuropsychological service delivery in these programs. Third, we presented preliminary data from the first six months of one of the pilot programs in order to examine incremental benefit of neuropsychology in improving patient care and parent satisfaction. MAIN FINDINGS: A total of 16 patients (age range three to 17 years) were seen by neuropsychology within the first six months of the program. Results showed that integration of neuropsychology into follow-up care resulted in recommendations being made for services or concerns not already addressed in 81% of cases. Parents reported high satisfaction, endorsing the highest possible rating on 96% of all items. Parents reported that neuropsychological consultation improved their understanding and communication with their child, and helped them know what to expect from their child during postacute recovery. CONCLUSIONS: The results of this pilot study suggest that integration of neuropsychology into neurocritical care follow-up programs contributes to parent satisfaction and may provide incremental benefit to patient care.
