Implementing guidelines: Proposed definitions of neuropsychology services in pediatric oncology

Neuropsychological Late Effects and Quality-of-Life Outcomes in Pediatric Brain Tumor Survivors: Role of Pediatric Neurologists in Monitoring and Management

Pediatric brain tumor (PBT) survivors are at significantly increased risk of cognitive, psychosocial, and educational/vocational sequelae that impact health-related quality of life. These complications and health morbidities result in high burden on survivors and their families, particularly those already vulnerable to disparities in health care access and outcomes. Since neurological comorbidities are common in this population, neurologists are uniquely positioned to screen, treat identified symptoms, and connect families with services and resources. A tiered assessment approach can facilitate early identification of concerns and reduce barriers to care. We review common presenting conditions, highlight risk factors, and provide screening tools and recommendations to facilitate comprehensive survivorship care for PBT survivors.

A clinical evaluation program to monitor neurocognitive risk in children and adolescents with sickle cell disease

Objective: Sickle cell disease (SCD) is an inherited hematologic disorder that impacts approximately 100,000 Americans. This disease is associated with progressive organ damage, cerebral vascular accident, and neurocognitive deficits. Recent guidelines from the American Society of Hematology (ASH) recommend cognitive screening with a psychologist to help manage cerebrovascular risk and cognitive impairment in this population. SCD patients benefit from neuropsychology services and several institutions already have programs in place to monitor cognitive risk. Program Description: We describe a longitudinal neurocognitive evaluation program at our institution that serves all patients with SCD, regardless of disease severity or referral question. The Sickle Cell Assessment of Neurocognitive Skills (SCANS) program was established in 2012. We outline the program's theoretical framework, timepoints for evaluation, test battery, logistics, patient demographics, integration with research programming, and multidisciplinary collaboration to support optimal outcomes. Program Outcomes: Our program has provided 716 targeted neuropsychological evaluations for patients over the last decade. Nearly 26% of patients in the program have been followed longitudinally. The most common diagnoses generated across cross-sectional and longitudinal evaluations include cognitive disorder (n = 191), attention-deficit/hyperactivity disorder (n = 75), and specific learning disorder (n = 75). Approximately 87% of patients who participated in SCANS during late adolescence successfully transitioned from pediatric to adult care. Conclusion: We discuss considerations for developing programming to meet the needs of this population, including tiered assessment models, timing of evaluations, scope, and reimbursement. Program models that utilize prevention-based tiered models or targeted evaluations can assist with serving large volumes of patients.

From Evidence-Based Guidelines to Clinical Practice: Pediatric Neuropsychology Care in Multidisciplinary Clinics

OBJECTIVE

High demand for pediatric neuropsychological care has highlighted the time- and resource-intensive nature of traditional comprehensive evaluations. Emerging care models address these constraints by facilitating tiered neuropsychological services provided in various contexts, including multidisciplinary clinics (MDCs). We aim to demonstrate feasibility and acceptability of tiered neuropsychological care in MDCs through examples from a single institution.

METHODS

A review of all current MDC practices at a tertiary pediatric care center was conducted to describe clinic workflow, services provided, and triage strategies. Pediatric neuropsychologists (n = 5) and other health care providers (n = 31) completed a survey focused on experience with neuropsychology consultation in MDCs.

RESULTS

Neuropsychologists provided care in 11 MDCs, including universal monitoring with consultative interviews and questionnaires, as well as targeted screening. Neuropsychologists (89%) and other health professionals (100%) reported that tiered neuropsychological services improved patient care within MDCs. Other health professionals reported utilizing results from neuropsychology MDC care to inform their clinical approach (48-90%), referrals (58%), and treatment or surveillance decisions (55-71%).

CONCLUSION

Tiered neuropsychological care in pediatric MDCs is feasible, and provider experience ratings indicate high acceptability. Practical steps for development of MDCs are provided, including identifying teams, clinic goals and outcomes, operational logistics, and billing.

Neurocognition in Pediatric Temporal Lobe Tumor-Related Epilepsy

Tumor-related epilepsy is a common and understudied neurological comorbidity among pediatric temporal lobe tumor patients that poses risk for neurocognitive impairment (NCI). Forty-one youth with either TLT+ (n = 23) or nonneoplastic temporal lobe epilepsy (n = 18) ages 6-20 years completed routine neuropsychological evaluations. Rates of NCI were similar across groups; however, NCI was more common in nonneoplastic participants on a task of phonemic fluency, p = .047. Younger age of seizure onset and greater number of antiseizure medications were associated with NCI among TLT+ participants only. Preliminary findings suggest separate prognostic models of cognitive outcomes between TLT+ and nonneoplastic epilepsy populations may be needed.

Developmental and adaptive functioning of very young children with solid tumors and brain tumors

PURPOSE

Infancy/toddlerhood is a period of rapid development. All infants/toddlers (0-36 months-of-age) undergoing cancer-directed treatment at one hospital are offered developmental assessments and related services. Yet, literature comparing development of infants/toddlers with brain tumors to those with non-CNS solid tumors is sparse.

DESIGN AND METHODS

Developmental assessment data were abstracted from electronic health records of infants/toddlers undergoing treatment for a brain tumor (n = 36; mean age = 21.83 ± 9.96 months) or a solid tumor (n = 40; mean age = 17.35 ± 8.50). Z-scores compared obtained data with age expectations. Chi-square analyses assessed whether a greater proportion of participants scored within the clinical range than normative expectations. Multivariate analysis of variance and chi-square analyses compared developmental outcomes between groups.

RESULTS

Compared with age expectations, the overall group demonstrated significantly less well-developed skills. Infants/toddlers with solid tumors demonstrated clinical deficits at rates higher than expected for most domains; the rate of impairment for the solid tumor group did not differ significantly from that of the brain tumor group across most subtests.

CONCLUSIONS

Like young patients with brain tumors, the developmental functioning of infants/toddlers with solid tumors should be studied across time to determine the trajectory of functioning for these young patients and to inform future developmental intervention studies.

PRACTICE IMPLICATIONS

Infants/toddlers with a malignant solid tumor may be at increased risk for delayed development. These very young patients would likely benefit from developmental assessment, early intervention services during and after treatment, and ongoing monitoring of development across time.

Clinical practice guidelines for the care of girls and women with Turner syndrome

Turner syndrome (TS) affects 50 per 100 000 females. TS affects multiple organs through all stages of life, necessitating multidisciplinary care. This guideline extends previous ones and includes important new advances, within diagnostics and genetics, estrogen treatment, fertility, co-morbidities, and neurocognition and neuropsychology. Exploratory meetings were held in 2021 in Europe and United States culminating with a consensus meeting in Aarhus, Denmark in June 2023. Prior to this, eight groups addressed important areas in TS care: (1) diagnosis and genetics, (2) growth, (3) puberty and estrogen treatment, (4) cardiovascular health, (5) transition, (6) fertility assessment, monitoring, and counselling, (7) health surveillance for comorbidities throughout the lifespan, and (8) neurocognition and its implications for mental health and well-being. Each group produced proposals for the present guidelines, which were meticulously discussed by the entire group. Four pertinent questions were submitted for formal GRADE (Grading of Recommendations, Assessment, Development and Evaluation) evaluation with systematic review of the literature. The guidelines project was initiated by the European Society for Endocrinology and the Pediatric Endocrine Society, in collaboration with members from the European Society for Pediatric Endocrinology, the European Society of Human Reproduction and Embryology, the European Reference Network on Rare Endocrine Conditions, the Society for Endocrinology, and the European Society of Cardiology, Japanese Society for Pediatric Endocrinology, Australia and New Zealand Society for Pediatric Endocrinology and Diabetes, Latin American Society for Pediatric Endocrinology, Arab Society for Pediatric Endocrinology and Diabetes, and the Asia Pacific Pediatric Endocrine Society. Advocacy groups appointed representatives for pre-meeting discussions and the consensus meeting.

Teacher Perspectives of Pediatric Neuropsychology and Supporting Children With Chronic Health Conditions

OBJECTIVE

The goal of the present study was to examine teachers' perceptions of neuropsychological reports broadly and their preparedness to support the educational needs of students with chronic health conditions.

METHOD

Teachers were selected from across the United States using stratified random sampling. 280 teachers (76.2% female; 58.4% public school; 53.9% rural setting) completed an anonymous electronic survey via Qualtrics.

RESULTS

Half of the teachers were familiar with neuropsychology and previously read a neuropsychological report, which the majority found useful with a preference toward shorter reports. Most found listed recommendations to be appropriate, but half of teachers identified limited resources as a barrier to implementation. Teachers reported limited education, training, and comfort for providing accommodations to children with chronic health conditions, which was significantly lower for cancer, congenital heart disease, and sickle cell disease. Older teachers, more years of experience, and special education teachers demonstrated significantly higher levels of education, training, and comfort. Frequency of implementing accommodations was significantly negatively correlated with perceived burden and positively correlated with perceived benefit across most accommodations. Teachers reported a preference for single-page handouts and speaking directly to neuropsychologists about the specific learning needs of students with chronic health conditions.

CONCLUSIONS

Results highlight areas for future research and intervention regarding teacher's preparedness for working with children with chronic health groups and opportunities to improve communication between neuropsychologists and teachers to ultimately improve access to educational supports and overall quality of life of students with chronic health conditions.

"The place it puts us in emotionally and relationally with our child, it's damaging": understanding the real-world psychosocial needs of caregivers of childhood cancer survivors

PURPOSE

Understanding the lived experiences of childhood cancer caregivers can guide the development of effective psychosocial models of care. We conducted this qualitative study to understand triggers that impact the mental health, quality of life, and mental health supportive care needs of caregivers.

METHODS

A maximum variation sampling strategy was used to recruit study participants for semi-structured interviews. Using a grounded theory approach, transcripts were independently dual-coded using inductive thematic analysis. We conducted a secondary thematic analysis emphasizing the impact of pediatric oncology on caregiver mental health.

RESULTS

Our findings highlight caregiver experiences connected to their child's appearance, quality of life, or change in behavior. Caregivers reported the need to transition between the role of nurturer and protector and simultaneously be part of the care team, which increased trauma for caregivers and their children. Caregivers noted that the hardest part of being a caregiver is witnessing, participating, and forcing the child to comply with cancer treatment. Caregivers were left wishing there had been more support for these situations.

CONCLUSION

Our findings reveal real-world experiences that caregivers view as among the most stressful during their child's cancer journey. These events provide insight into the nuanced and most difficult experiences from the caregiver perspective in which emotional support services would be most useful. These insights will inform a future model for mental healthcare.

IMPLICATIONS FOR CANCER SURVIVORS

Caregivers' treatment-related stress is associated with the quality of life of pediatric cancer patients. Supporting the mental health, quality of life, and mental health supportive care needs of childhood cancer caregivers through supportive care guidelines may positively impact the caregiver-child relationship long into survivorship.  Children's and their caregivers' treatment-related stress are indelibly connected to the quality of life concerns throughout the cancer journey. Supporting the mental health, quality of life, and mental health supportive care needs of childhood cancer caregivers through supportive care guidelines will positively impact the caregiver-child relationship long into survivorship.

Cognitive issues in patients with IDH mutant gliomas: from neuroscience to clinical neuropsychology

PURPOSE

The understanding of cognitive symptoms in patients with IDH-Mutant gliomas (IDH-Mut) is rapidly developing. In this article, we summarize the neuroscientific knowledge base regarding the influence of IDH-Mut tumors and their treatment on cognition and provide guidance regarding the management of these symptoms in patients.

METHODS

We performed a review of peer reviewed publications relevant to IDH-Mut glioma and cognitive outcomes and provide an overview of the literature as well as a case example to clarify management strategies.

RESULTS

At the time of presentation, patients with IDH-Mut gliomas have a favorable cognitive profile as compared with those with IDH-wild type (WT) tumors. The relatively low cognitive burden may reflect the slower growth rate of IDH-Mut tumors, which is less disruptive to both local and widespread neural networks. Human connectomic research using a variety of modalities has demonstrated relatively preserved network efficiency in patients with IDH-Mut gliomas as compared with IDH-WT tumors. Risk of cognitive decline from surgery can potentially be mitigated by careful integration of intra-operative mapping. Longer term cognitive risks of tumor treatment, including chemotherapy and radiation, are best managed by instituting neuropsychological assessment as part of the long-term care of patients with IDH-Mutant glioma. A specific timeline for such integrative care is provided.

CONCLUSIONS

Given the relative recency of the IDH-mutation based classification of gliomas, as well as the long time course of this disease, a thoughtful and comprehensive strategy to studying patient outcomes and devising methods of cognitive risk reduction is required.

Schulische Reintegration von Kindern und Jugendlichen mit einem ZNS-Tumor

Zusammenfassung: Unterstützung bei der schulischen Reintegration wird als standard of care in der pädiatrischen Onkologie definiert. Ziel ist die Bereitstellung von Informationen und die Koordination der Kommunikation zwischen Patient_in/Familie, Schule und Krankenhaus. Dies ist von entscheidender Bedeutung für Schüler_innen mit Tumoren des Zentralnervensystems (ZNS), insbesondere in der Nachsorge, da sie eine Risikogruppe für Spätfolgen darstellen. Um die Kooperation zu verbessern, wurden mehrere praktische Unterstützungsmöglichkeiten eingeführt. Im Rahmen des vorgestellten Pilotprojekts wurde darüber hinaus ein Webinar konzipiert und evaluiert, das speziell auf die Fragen von externen Lehrer_innen eingeht. Die Ergebnisse zeigen, dass eine Online-Informationsveranstaltung das notwendige Wissen und die Zusammenarbeit verbessern kann, verdeutlichen gleichzeitig aber auch die Wichtigkeit der kontinuierlichen Unterstützung in Form von Expert_innen für schulische Reintegration, um Schüler_innen mit ZNS-Tumoren angemessen zu begleiten.

Neuropsychological surveillance model for survivors of pediatric cancer: A descriptive report of methodology and feasibility

Objective: Neuropsychological late effects of pediatric cancer may not become apparent for years after therapy; therefore, serial monitoring is necessary for detecting changes to ensure timely intervention. Unfortunately, lack of access to neuropsychologists, increased patient volume, insurance authorization and reimbursement issues, time required for neuropsychological evaluation, and practice effects related to repeat testing present many challenges to provision of neuropsychological care for survivors of childhood cancer. Models involving surveillance and monitoring have been proposed, though minimal data exist related to the implementation and feasibility of such models. Method: In this descriptive feasibility study, the Neuropsychology Consult Clinic (NCC) at Children's Hospital Los Angeles is presented, outlining a methodology and algorithm for neuropsychological surveillance of survivors of non-CNS pediatric cancer and an account of the first three years of clinic implementation. Participants included 215 survivors (x̅ age = 5.6 years), including 75.3% Latinx patients. Results: The overall clinic implementation was found to be feasible, with approximately 75% of patients "passing" the screening and 25% "failing" the screening. Clinical judgment only conflicted with the algorithm 8.6% of the time. However, several limitations to feasibility were noted, including validity concerns and ability/time to complete parent-reported outcomes using Spanish forms, as well as access to bilingual examiners. Conclusions: These preliminary data support the feasibility of the NCC model with limitations as outlined above. This is the first phase in a multiphase plan to develop an appropriate screening clinic for survivors of pediatric cancer, with the next phase focusing on sensitivity/specificity of measures.

Cognitive predictors of social adjustment in pediatric brain tumor survivors treated with photon versus proton radiation therapy

BACKGROUND

Pediatric brain tumor survivors are at risk for poor social outcomes. It remains unknown whether cognitive sparing with proton radiotherapy (PRT) supports better social outcomes relative to photon radiotherapy (XRT). We hypothesized that survivors treated with PRT would outperform those treated with XRT on measures of cognitive and social outcomes. Further, we hypothesized that cognitive performance would predict survivor social outcomes.

PROCEDURE

Survivors who underwent PRT (n = 38) or XRT (n = 20) participated in a neurocognitive evaluation >1 year post radiotherapy. Group differences in cognitive and social functioning were assessed using analysis of covariance (ANCOVA). Regression analyses examined predictors of peer relations and social skills.

RESULTS

Age at evaluation, radiation dose, tumor diameter, and sex did not differ between groups (all p > .05). XRT participants were younger at diagnosis (XRT M = 5.0 years, PRT M = 7.6 years) and further out from radiotherapy (XRT M = 8.7 years, PRT M = 4.6 years). The XRT group performed worse than the PRT group on measures of processing speed (p = .01) and verbal memory (p < .01); however, social outcomes did not differ by radiation type. The proportion of survivors with impairment in peer relations and social skills exceeded expectation; χ² (1) = 38.67, p < .001; χ² (1) = 5.63, p < .05. Household poverty predicted peer relation difficulties (t = 2.18, p < .05), and verbal memory approached significance (t = -1.99, p = .05). Tumor diameter predicted social skills (t = -2.07, p < .05).

CONCLUSIONS

Regardless of radiation modality, survivors are at risk for social challenges. Deficits in verbal memory may place survivors at particular risk. Results support monitoring of cognitive and social functioning throughout survivorship, as well as consideration of sociodemographic risk factors.

Changes in executive function in pediatric brain tumor survivors

OBJECTIVE

Pediatric oncology survivors are at risk for executive function (EF) and working memory (WM) deficits, which can be measured via performance-based measures or rating scales. Previous studies have shown these measurement methods to be weakly correlated. This study aimed to describe parent-rated EF and performance-based WM (PBWM) in pediatric brain tumor (BT) survivors, examine change in EF and PBWM across time, and investigate the relationship between parent-rated WM and PBWM.

METHOD

The sample included 56 patients diagnosed with a BT in childhood (M_age  = 6.94 years; SD = 4.05) seen twice for clinical neuropsychological evaluation. PBWM was examined via the auditory WM scale from a Wechsler intelligence measure or Differential Ability Scales-II. Parents completed the Behavior Rating Inventory of Executive Function (BRIEF)/BRIEF-P/BRIEF-2 as a measure of global EF (Global Executive Composite [GEC]), metacognitive skills (Metacognitive Index/Cognitive Regulation Index [MI/CRI]), behavioral regulation (Behavior Regulation Index [BRI]), and emotional regulation (Emotion Regulation Index [ERI]).

RESULTS

GEC, MI/CRI, and ERI at Time 1 were significantly above the mean (p < .01); BRI and PBWM did not differ from the normative mean. All measures were significantly higher than the normative mean at Time 2 (p < .05). PBWM was both clinically and statistically elevated (p < .001). There was a significant change across time in PBWM (p < .05), but not GEC, MI/CRI, ERI, or BRI. PBWM was weakly correlated with the BRIEF WM subscale at Time 1 and Time 2 (all p > .05).

CONCLUSIONS

Multiple measures of EF should be considered when providing diagnoses and recommendations for pediatric BT survivors. Furthermore, given declines across time, findings document need for continued monitoring and reassessment of survivors as they get further out from treatment.

Integrating Telehealth Into Neurodevelopmental Assessment: A Model From the Cardiac Neurodevelopmental Outcome Collaborative

Objective

In the wake of the COVID-19 pandemic, psychologists were pushed to look beyond traditional in-person models of neurodevelopmental assessment to maintain continuity of care. A wealth of data demonstrates that telehealth is efficacious for pediatric behavioral intervention; however, best practices for incorporating telehealth into neurodevelopmental assessment are yet to be developed. In this topical review, we propose a conceptual model to demonstrate how telehealth can be incorporated into various components of neurodevelopmental assessment.

Methods

Harnessing existing literature and expertise from a multidisciplinary task force comprised of clinicians, researchers, and patient/parent representatives from the subspecialty of cardiac neurodevelopmental care, a conceptual framework for telehealth neurodevelopmental assessment was developed. Considerations for health equity and access to care are discussed, as well as general guidelines for clinical implementation and gaps in existing literature.

Results

There are opportunities to integrate telehealth within each stage of neurodevelopmental assessment, from intake to testing, through to follow-up care. Further research is needed to determine whether telehealth mitigates or exacerbates disparities in access to care for vulnerable populations as well as to provide evidence of validity for a wider range of neurodevelopmental measures to be administered via telehealth.

Conclusions

While many practices are returning to traditional, face-to-face neurodevelopmental assessment services, psychologists have a unique opportunity to harness the momentum for telehealth care initiated during the pandemic to optimize the use of clinical resources, broaden service delivery, and increase access to care for pediatric neurodevelopmental assessment.

Neuropsychological Screening in Pediatric Multidisciplinary Clinics: Group Characteristics and Predictive Utility

OBJECTIVE

To evaluate the feasibility of administering caregiver-report neuropsychological screening measures in pediatric multidisciplinary clinics (MDCs) and investigate predictive utility for cognitive and academic difficulties on follow-up testing.

METHOD

The Pediatric Perceived Cognitive Functioning (Peds PCF) and Colorado Learning Difficulties Questionnaire (CLDQ) were administered to caregivers of youth with history of brain tumor (BT), non-central nervous system (CNS) cancer, or Fontan circulation as part of routine neuropsychological consultation in MDCs from 2017 to 2019. We examined cross-sectional differences on screening measures, and relationships between screening and intellectual and academic test performance in a subset who presented for follow-up neuropsychological evaluation. Receiver operating characteristic (ROC) curve analysis was used to identify suggested cut scores on screening measures for predicting who would most benefit from further evaluation.

RESULTS

Screening was completed with 192 families. Children with history of non-CNS cancer (n = 29) had fewer parent-reported cognitive and academic concerns compared with either BT (n = 88) or Fontan (n = 75) groups. Peds PCF and CLDQ scores were related to intellectual and academic test performance in the group presenting for neuropsychological evaluation (n = 68). ROC curve analysis identified cut scores across screening measures with maximal sensitivity and specificity for detecting neuropsychological difficulties.

CONCLUSIONS

It is feasible to utilize parent rating measures during neuropsychological consultation in pediatric MDCs. The Peds PCF and CLDQ demonstrated sensitivity to intellectual and academic difficulties in children with significant medical histories. Screening may be a helpful tool for pediatric neuropsychologists and other professionals during MDC consultation to inform clinical management.

Assessment and Management of Cognitive Symptoms in Patients With Brain Tumors

Cognitive symptoms occur in almost all patients with brain tumors at varying points in the disease course. Deficits in neurocognitive function may be caused by the tumor itself, treatment (surgery, radiation, or chemotherapy), or other complicating factors (e.g., seizures, fatigue, mood disturbance) and can have a profound effect on functional independence and quality of life. Assessment of neurocognitive function is an important part of comprehensive care of patients with brain tumors. In the neuro-oncology clinic, assessment may include cognitive screening tools and inquiry into subjective cognitive function. Neuropsychological assessment is an important adjunct to identify cognitive symptoms and can be used as an opportunity to intervene through transformative feedback and treatment planning. Preventative measures can be taken to reduce cognitive side effects of treatment, such as awake craniotomies with intraoperative mapping during neurosurgery or prophylactic measures during radiation therapy (e.g., hippocampal avoidance, neuroprotectant treatment with memantine). Rehabilitative therapies, including cognitive rehabilitation and computerized cognitive exercise, are options for managing cognitive problems in an individualized manner. Pharmacotherapy, including use of stimulant medications and acetylcholinesterase inhibitors, has shown benefits for patients with brain tumors when tailored to an individual's cognitive profile. Identification and management of co-occurring issues, such as sleep disturbance, fatigue, and depression, can also improve neurocognitive function. There are promising therapies under development that may provide new options for treatment in the future. Integrating careful assessment and treatment of cognition throughout the disease course for patients with brain tumors can improve functional outcomes and quality of life.

Difficulties encountered by physicians and mental health professionals in evaluating and caring for affective and behavioral problems in pediatric brain tumor survivors

BACKGROUND

Pediatric brain tumor survivors (PBTS) present a high risk for emotional and behavioral disorders. When addressing these difficulties, differences in study designs; variety of and disagreement about diagnoses; and intricate links of emotional, behavioral, and cognitive issues may complicate the interpretation of studies and probably also the work of clinicians. We aimed to survey the difficulties perceived by physicians and mental health professionals in their practice and their interest in developing a new evaluative tool.

METHODOLOGY

We surveyed 29 health professionals involved in the follow-up of this population. They completed questionnaires about their clinical practice (difficulties, needs, activities) and indicated diagnosis hypotheses and treatment plans on a clinical case developed for this study.

RESULTS

Emotional and behavioral disorders were reported as difficult to assess for 93% of participants. The overlap of symptoms (90%) and the lack of an adapted diagnostic framework (90%) were the main reasons mentioned. Respectively 93%, 90%, and 65% of participants would at least "often" make referrals to psychological (93%), neuropsychological (90%), and psychiatric (65%) assessments and care. Family and group therapy were less common as was drug management. All participants were in favor of creating a tool to help with diagnosis and treatment. When responding to a clinical case, the heterogeneity of participants' responses highlighted their issues in diagnosing and managing these patients.

CONCLUSION

This survey exemplifies the difficulties of health professionals related to the evaluation and management of affective and behavioral disorders experienced by PBTS. It underlines the need to help professionals by initiating systematic assessment strategies with this vulnerable population.

Pre-appointment online assessment of patient complexity: Towards a personalized model of neuropsychological assessment

Recent events such as the global pandemic of COVID-19 have challenged neuropsychologists to scale up their capacity to conduct portions of their assessment remotely. While more complex patients will likely continue to require on-site, office-based interaction and assessment, the current emergency-based expansion of online and telehealth evaluation practices may ultimately lay the groundwork for more routine, online assessment of patients with less complex presentations in the future. To this end, the current study evaluated a pre-appointment, online methodology for differentiating referred pediatric patients based upon the scope and severity of their caregiver-reported adaptive, academic, attentional, behavioral, and emotional impairment. Prior to on-site assessment, parents/caregivers of 2197 children (Mean age = 10.0y, range = 4-19y, 62% male) completed an online developmental history form screening for symptoms of adaptive, attentional, learning, affective, and behavioral impairment; 71% of those children eventually underwent assessment. Using latent class analysis, the data supported a reproducible 4-class model consisting of groups of children at increased risk for: 1) severe multi-domain dysfunction; the "High Complexity" group, 30%, 2) behavioral-affective (but not academic) dysregulation; the "Behavioral Focus" group, 13%, 3) academic (but not behavioral-affective) problems; the "Academic and Inattention" group, 37%, and 4) patients with minimal clinical complexity; the "Low Complexity" group, 20%. Comparison of pre-visit classification with day-of-assessment standardized test scores supported the validity of patient subtypes. Moving forward, pre-appointment clarification of patient complexity may support efficient patient triage with regard to assessment modality (e.g., on-site or online) and length of appointment (e.g., comprehensive or targeted).

Young Adult Cancer Survivorship: Recommendations for Patient Follow-up, Exercise Therapy, and Research

Survivors of adolescent and young adult cancers (AYAs) often live 50 to 60 years beyond their diagnosis. This rapidly growing cohort is at increased risk for cancer- and treatment-related 'late effects' that persist for decades into survivorship. Recognition of similar issues in pediatric cancer survivors has prompted the development of evidence-based guidelines for late effects screening and care. However, corresponding evidence-based guidelines for AYAs have not been developed. We hosted an AYA survivorship symposium for a large group of multidisciplinary AYA stakeholders (approximately 200 were in attendance) at Princess Margaret Cancer Centre (Toronto, Ontario, Canada) to begin addressing this disparity. The following overview briefly summarizes and discusses the symposium's stakeholder-identified high-priority targets for late effects screening and care and highlights knowledge gaps to direct future research in the field of AYA survivorship. This overview, although not exhaustive, is intended to stimulate clinicians to consider these high-priority screening and care targets when seeing survivors in clinical settings and, ultimately, to support the development of evidence-based late effects screening and care guidelines for AYAs.

Barriers to Schooling in Survivorship: The Role of Neuropsychological Assessment

PURPOSE

Pediatric cancer survivorship rates continue to improve, although disease- and treatment-related neurocognitive impacts substantively affect survivors' educational access and availability for learning. Receiving formal educational supports substantially improves survivors' academic progress and graduation rates; however, parents of survivors report obtaining such support is stressful, in part due to limited knowledge on their part and that of their oncology providers.

METHODS

Parents (N = 195) of pediatric survivors across the United States were surveyed to explore specific barriers to obtaining appropriate educational supports and the facilitating role of the oncologist.

RESULTS

Parent-reported barriers included limited access to formal educational supports, under-referral to neuropsychology services, and need for more information about available supports and how best to advocate for these, when needed. Not only were few survivors (35.4%) referred for neuropsychological evaluation, standard of care for many pediatric survivors, but survivors were more than five times more likely to be retained in grade compared with the national retention rate. When obtained, parents reported that the neuropsychological consultation and associated report were helpful in increasing their own understanding and addressing barriers to obtaining adequate supports for their children.

CONCLUSION

Given the important role of neuropsychological evaluation for survivors and their families, bringing referral rates more in line with national guidelines represents a critical target for oncologists. With adequate training in relevant issues, the oncologist is positioned to be a key support to survivors and their families in ensuring access to neuropsychological services and reducing barriers to an appropriate education.

Facilitating Transitions to Adulthood in Pediatric Brain Tumor Patients: the Role of Neuropsychology

PURPOSE OF REVIEW

Transition-age patients with history of a pediatric brain tumor are at significant risk for difficulties transitioning to adulthood. We review current transition models and the potential role of neuropsychology in the transition process for adolescent and young adult brain tumor survivors.

RECENT FINDINGS

Several recently developed healthcare transition models include consideration of patients' cognitive and functional capacities, yet currently available transition readiness tools are limited in scope and do not possess adequate normative data across pediatric medical populations. We explore the potential utility and added benefit of systematically incorporating neuropsychology in the transition process for pediatric brain tumor survivors. The literature supports increased evaluation and intervention targeted at psychosocial barriers to transition. Based on these findings, we propose a family-centered and multidisciplinary care model that promotes both medical and broader psychosocial transition processes. Neuropsychology is ideally suited to assess the wide-ranging areas encompassed in transition readiness and to facilitate the transition process.

Post-intensive care syndrome in a cohort of infants & young children receiving integrated care via a pediatric critical care & neurotrauma recovery program: A pilot investigation

OBJECTIVE

Children treated in the pediatric intensive care unit (PICU) often face difficulties with long-term morbidities associated with neurologic injuries and lifesaving PICU interventions termed Post-Intensive Care Syndrome (PICS). In an effort to identify and address critical issues related to PICS, we developed an integrated model of care whereby children and families participate in follow-up clinics with a neuropsychologist and a critical care physician. To demonstrate preliminary impact, we present pilot findings on the early identification and treatment of PICS in a cohort of infants and young children in our program through a combination of multi-professional direct assessment and parent proxy questionnaires.

METHOD

Thirty-three infants and children, ages 3-72 months, participated in our initial follow-up clinic where issues related to physical health/recovery, development/cognition, mood/behavior, and quality of life were screened 1-3 months after discharge from the PICU.

RESULTS

In comparison to pre-hospitalization functioning, direct assessment revealed new neurological concerns identified by the critical care physician in 33.3% of participants and new neurocognitive concerns identified by the neuropsychologist in 36.4% of participants. Caregiver reported measures showed significant issues with patient cognitive functioning, emotional functioning, sleep, and impact on the family. Participants and families experienced significant difficulties related to changes in functioning and disability. Parents/caregivers and clinicians demonstrated agreement on functioning across a variety of indicators; however, important divergence in assessments were also found highlighting the importance of multiple assessments and perspectives.

CONCLUSIONS

New PICS morbidities are common in the early phase of recovery after discharge in infants, young children and their families. Results demonstrate the benefits and need for timely PICU follow-up care that involves collaboration/integration of physicians, neuropsychologists, and families to identify and treat PICS issues.

Beyond Risk-Based Stratification: Impacts of Processing Speed and Executive Function on Adaptive Skills in Adolescent and Young Adult Cancer Survivors

Purpose: The number of adolescent and young adult (AYA) survivors of childhood cancer is increasing, and the impacts of therapy on their daily lives are not well understood. Adaptive functions are required for age-appropriate interactions and day to day functioning, but are reduced in AYA survivors. Work in other pediatric populations suggests that additional neurocognitive skills may influence adaptive function and, thus, quality of life and personal attainment of AYA cancer survivors. Methods: Retrospective medical records review examined neurocognitive data from 139 AYA survivors. Hierarchical linear regression examined age at diagnosis, use of central nervous system (CNS) radiation, verbal intelligence, processing speed, and executive function as predictors of adaptive functioning domains. Results: AYA survivors exhibited weaknesses in all domains of adaptive functioning compared to normative reference values (Cohen's d = 0.660-0.864), as well as in processing speed (Cohen's d = 0.791) and metacognitive executive functioning (Cohen's d = 0.817). Processing speed and executive function provided substantial improvements in prediction of adaptive functioning beyond that of age at diagnosis and use of CNS-directed radiation therapy. Taken together these variables explained 37.1% of variability in adaptive conceptual skills, 26.1% in adaptive social skills, and 27.1% of adaptive practical skills. Conclusions: Intelligence, processing speed, and executive function significantly contribute to adaptive function scores in AYA cancer survivors and impact domains that are important to self-sufficiency and quality of life. Attention to neurocognitive function in all AYA cancer survivors is recommended in addition to referral for neuropsychological evaluation and tailoring interventions to address executive and adaptive functioning.

Neurodevelopmental Consequences of Pediatric Cancer and Its Treatment: The Role of Sleep

Cognitive impairment is frequent in pediatric cancer, and behavioral and psychological disturbances often also affect children who have survived cancer problems. Furthermore, pediatric tumors are also often associated with sleep disorders. The interrelationship between sleep disorders, neurodevelopmental disorders and pediatric cancer, however, is still largely unexplored. In this narrative review we approach this important aspect by first considering studies on pediatric cancer as a possible cause of neurodevelopmental disorders and then describing pediatric cancer occurring as a comorbid condition in children with neurodevelopmental disorders. Finally, we discuss the role of sleep disorders in children with cancer and neurodevelopmental disorders. Even if the specific literature approaching directly the topic of the role of sleep in the complex relationship between pediatric cancer and neurodevelopmental disorders was found to be scarce, the available evidence supports the idea that in-depth knowledge and correct management of sleep disorders can definitely improve the health and quality of life of children with cancer and of their families.

Pediatric oncology provider perspectives and practices: Supporting patients and families in schooling after cancer diagnosis

BACKGROUND

Cognitive limitations are common after childhood cancer and require assessment and support in the medical and school setting. Pediatric oncology providers are tasked with educating families about the side effects of disease/treatment, and supporting families as they navigate the associated challenges. Despite this important role, little is known about the training, practice, and knowledge of providers in the domain of cognitive/school impacts.

METHODS

An online survey was emailed to Children's Oncology Group (COG) member physicians in the United States. The survey consisted of 42 questions about training and practice, and 4 knowledge questions about neurocognitive impacts and school supports.

RESULTS

Surveys were completed by 282 physicians representing 64% of COG institutions and a diverse group of experience and institution size. The pediatric oncologist was reported most frequently (93%) as the person at their institution to provide information to families on this topic, yet 54% reported receiving no specific training in this area and the majority (66%) reported to only "somewhat" understand the issues pediatric oncology patients face when returning to school. A minority reported available institutional guidelines (42%) or screening tools (19%) to assist in making referrals or assessments. Knowledge questions concerning health conditions qualifying children for school supports received the fewest correct answers. The majority (77%) thought more training would be helpful.

CONCLUSIONS

Additional training about cognitive impacts and schooling challenges associated with childhood cancer is needed to prepare providers to support parents/children. In addition, establishing policy guidelines and screening procedures may help support providers in providing care.

Late effects of pediatric brain tumors

PURPOSE OF REVIEW

Adverse late effects of pediatric brain tumors can be numerous and complex and potentially alter the life trajectories of survivors in a multitude of ways. We review these inter-related late effects that compromise neurocognitive function, general health, social and psychological adjustment, and overall adaptive and vocational outcomes, and threaten to undermine the ability of survivors to transition independently into adulthood and effectively manage their care. Intervention/prevention strategies and advances in treatment that may reduce such late effects are discussed.

RECENT FINDINGS

Studies of neuropsychological late effects have revealed specific deficits in core cognitive functions of attention, working memory and processing speed, with many survivors demonstrating decline in working memory and processing speed over time, irrespective of tumor type or treatment. This in turn affects the ongoing development of higher order neurocognitive skills. Research also highlights the increasing burden of health-related, neuropsychological and psychosocial late effects into adulthood and impact across life outcomes.

SUMMARY

Pediatric brain tumor survivors require coordinated interdisciplinary care, ongoing evaluation and management of late effects, and timely interventions focused on mitigating the impact of late effects. The transition to adulthood can be especially vulnerable and addressing barriers to care is of paramount importance.

Monitoring of Neurocognitive Function in the Care of Patients with Brain Tumors

PURPOSE OF REVIEW

A detailed characterization of the nature of neurocognitive impairment in patients with brain tumors is provided, as well as considerations for clinical practice regarding neuropsychological assessment throughout the disease course.

RECENT FINDINGS

Neurocognitive impairment is common in patients with brain tumors and may result from the tumor itself, as a consequence of treatment, including surgery, chemotherapy, and radiation, or in association with supportive care medications (e.g., anticonvulsant and pain medications). Serial surveillance of neurocognitive functioning in this population can facilitate medical decision-making and inform recommendations to improve patient daily functioning and quality of life. Neuropsychological assessment is increasingly recognized as a critical component of the multidisciplinary care of patients with brain tumors and has already had practice-changing effects. Further understanding of genetic risk factors for neurocognitive decline along with the development of novel assessment and intervention strategies may further enhance functioning and general well-being in this patient population.

Attention-mediated neurocognitive profiles in survivors of pediatric brain tumors: comparison to children with neurodevelopmental ADHD

Background

Attention and working memory symptoms are among the most common late effects in survivors of pediatric brain tumors, and are often associated with academic and psychosocial difficulties. Diagnostic and treatment approaches derived from the literature on attention-deficit hyperactivity disorder (ADHD) have frequently been applied to survivors, yet the extent of overlap in cognitive profiles between these groups is unclear. The objective of the present study is to compare neurocognition in survivors of brain tumors and children with neurodevelopmental ADHD.

Methods

Neuropsychological data were abstracted from clinically referred brain tumor survivors (n = 105, Mage = 12.0 y, 52.4% male) and children with ADHD (n = 178, Mage = 11.1 y, 64.0% male). Data consist of a battery of parent-report questionnaires and performance-based neuropsychological measures.

Results

Twenty-five survivors (23.8%) of pediatric brain tumors met symptom criteria for ADHD. Participants with neurodevelopmental ADHD and survivors who met ADHD criteria had significantly greater parent- (P < 0.001) and teacher-reported (P < 0.001) working memory and behavior regulation difficulties than survivors of tumor who did not meet criteria. Children with ADHD symptoms also performed worse on measures of sustained attention than survivors without ADHD symptoms (P < 0.001). Additionally, survivors with ADHD symptoms had greater performance-based working memory difficulties than either survivors without attention problems or children with neurodevelopmental ADHD (P = 0.002).

Conclusions

Nearly a quarter of survivors with attention symptoms have functional profiles that are similar to children with neurodevelopmental ADHD. They also experience more neurocognitive impairments than survivors without attentional difficulties, particularly in working memory. Screening for ADHD symptoms may help providers triage a subset of individuals in need of earlier or additional neuropsychological assessment.

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.

Neurocognitive and Psychosocial Outcomes in Pediatric Brain Tumor Survivors

The late neurocognitive and psychosocial effects of treatment for pediatric brain tumor (PBT) represent important areas of clinical focus and ongoing research. Neurocognitive sequelae and associated problems with learning and socioemotional development negatively impact PBT survivors' overall health-related quality of life, educational attainment and employment rates. Multiple factors including tumor features and associated complications, treatment methods, individual protective and vulnerability factors and accessibility of environmental supports contribute to the neurocognitive and psychosocial outcomes in PBT survivors. Declines in overall measured intelligence are common and may persist years after treatment. Core deficits in attention, processing speed and working memory are postulated to underlie problems with overall intellectual development, academic achievement and career attainment. Additionally, psychological problems after PBT can include depression, anxiety and psychosocial adjustment issues. Several intervention paradigms are briefly described, though to date research on innovative, specific and effective interventions for neurocognitive late effects is still in its early stages. This article reviews the existing research for understanding PBT late effects and highlights the need for innovative research to enhance neurocognitive and psychosocial outcomes in PBT survivors.

DIVERGT screening procedure predicts general cognitive functioning in adult long-term survivors of pediatric acute lymphoblastic leukemia: A PETALE study

BACKGROUND

Acute lymphoblastic leukemia (ALL) is the most common cancer in children. Because of major improvements in treatment protocols, the survival rate now exceeds 80%. However, ALL treatments can cause long-term neurocognitive sequelae, which negatively impact academic achievement and quality of life. Therefore, cognitive sequelae need to be carefully evaluated. The DIVERGT is a battery of tests proposed as a screening tool, sensitive to executive function impairments in children and adolescent cancer survivors. Our study aimed at verifying the predictive value of the DIVERGT on general cognitive functioning in adult long-term survivors of ALL.

METHODS

ALL survivors completed the DIVERGT 13.4 years, on average, after remission (N = 247). In addition, 49 of these survivors (equally selected amongst those with low, average, and high DIVERGT scores) as well as 29 controls completed a more comprehensive neuropsychological evaluation within a 3-year period from DIVERGT administration. Multivariate regression analysis was used to assess the predictive value of the DIVERGT on general intelligence, mathematics, verbal memory, and working memory. As a follow-up analysis, three performance groups were created based on the DIVERGT results. Multivariate analysis of variance (MANOVA) assessed neuropsychological differences between groups.

RESULTS

The DIVERGT accurately predicted General Ability Index (GAI) (P < 0.0001), mathematics (P < 0.0001) and verbal memory (P = 0.045). Moreover, the low-performance group consistently had poorer performance than the high-performance and control groups on the neuropsychological tests.

CONCLUSION

The DIVERGT is a useful, time-effective screening battery for broader neurocognitive impairments identification in long-term adult ALL survivors. It could be implemented as routine examination in cancer follow-up clinics.

Neurocognitive Outcomes and Interventions in Long-Term Survivors of Childhood Cancer

Recent research has demonstrated that survivors of childhood cancer are at risk for a myriad of late effects that affect physical and mental quality of life. We discuss the patterns and prevalence of neurocognitive problems commonly experienced by survivors of CNS tumors and acute lymphoblastic leukemia, the two most commonly researched cancer diagnoses. Research documenting the direct effects of tumor location and treatment type and intensity is presented, and patient characteristics that moderate outcomes (eg, age at diagnosis and sex) are discussed. Potential biologic mechanisms of neurotoxic treatment exposures, such as cranial irradiation and intrathecal and high-dose antimetabolite chemotherapy, are reviewed. Genetic, brain imaging, and neurochemical biomarkers of neurocognitive impairment are discussed. Long-term survivors of childhood cancer are also at risk for physical morbidity (eg, cardiac, pulmonary, endocrine) and problems with health behaviors (eg, sleep); research is reviewed that demonstrates these health problems contribute to neurocognitive impairment in survivors with or without exposure to neurotoxic therapies. We conclude this review with a discussion of literature supporting specific interventions that may be beneficial in the treatment of survivors who already experience neurocognitive impairment, as well as in the prevention of impairment manifestation.
