The research landscape of tuberous sclerosis complex–associated neuropsychiatric disorders (TAND)—a comprehensive scoping review

Background Tuberous sclerosis complex (TSC)–associated neuropsychiatric disorders (TAND) is an umbrella term for the behavioural, psychiatric, intellectual, academic, neuropsychological and psychosocial manifestations of TSC. Although TAND affects 90% of individuals with TSC during their lifetime, these manifestations are relatively under-assessed, under-treated and under-researched. We performed a comprehensive scoping review of all TAND research to date (a) to describe the existing TAND research landscape and (b) to identify knowledge gaps to guide future TAND research. Methods The study was conducted in accordance with stages outlined within the Arksey and O’Malley scoping review framework. Ten research questions relating to study characteristics, research design and research content of TAND levels and clusters were examined. Results Of the 2841 returned searches, 230 articles published between 1987 and 2020 were included (animal studies = 30, case studies = 47, cohort studies = 153), with more than half published since the term TAND was coined in 2012 (118/230; 51%). Cohort studies largely involved children and/or adolescents (63%) as opposed to older adults (16%). Studies were represented across 341 individual research sites from 45 countries, the majority from the USA (89/341; 26%) and the UK (50/341; 15%). Only 48 research sites (14%) were within low–middle income countries (LMICs). Animal studies and case studies were of relatively high/high quality, but cohort studies showed significant variability. Of the 153 cohort studies, only 16 (10%) included interventions. None of these were non-pharmacological, and only 13 employed remote methodologies (e.g. telephone interviews, online surveys). Of all TAND clusters, the autism spectrum disorder–like cluster was the most widely researched (138/230; 60%) and the scholastic cluster the least (53/200; 27%). Conclusions Despite the recent increase in TAND research, studies that represent participants across the lifespan, LMIC research sites and non-pharmacological interventions were identified as future priorities. The quality of cohort studies requires improvement, to which the use of standardised direct behavioural assessments may contribute. In human studies, the academic level in particular warrants further investigation. Remote technologies could help to address many of the TAND knowledge gaps identified

Updated international tuberous sclerosis complex diagnostic criteria and surveillance and management recommendations

Background Tuberous sclerosis complex (TSC) is an autosomal dominant genetic disease affecting multiple body systems with wide variability in presentation. In 2013, Pediatric Neurology published articles outlining updated diagnostic criteria and recommendations for surveillance and management of disease manifestations. Advances in knowledge and approvals of new therapies necessitated a revision of those criteria and recommendations. Methods Chairs and working group cochairs from the 2012 International TSC Consensus Group were invited to meet face-to-face over two days at the 2018 World TSC Conference on July 25 and 26 in Dallas, TX, USA. Before the meeting, working group cochairs worked with group members via e-mail and telephone to (1) review TSC literature since the 2013 publication, (2) confirm or amend prior recommendations, and (3) provide new recommendations as required. Results Only two changes were made to clinical diagnostic criteria reported in 2013: “multiple cortical tubers and/or radial migration lines” replaced the more general term “cortical dysplasias,” and sclerotic bone lesions were reinstated as a minor criterion. Genetic diagnostic criteria were reaffirmed, including highlighting recent findings that some individuals with TSC are genetically mosaic for variants in TSC1 or TSC2. Changes to surveillance and management criteria largely reflected increased emphasis on early screening for electroencephalographic abnormalities, enhanced surveillance and management of TSC-associated neuropsychiatric disorders, and new medication approvals. Conclusions Updated TSC diagnostic criteria and surveillance and management recommendations presented here should provide an improved framework for optimal care of those living with TSC and their families

Reintegration into school after treatment for a brain tumor : the child\u2019s perspective

This multiple case study investigated perspectives of childhood brain tumor survivors on reintegration into school over a 2-year period. Semistructured interviews were conducted with 5 children at 3 times to obtain an extensive view of their overall school experience. Thematic analysis of data resulted in 4 themes: “school life and participation,” “peer relations and friendships,” “performance and difficulties,” and “support and follow-up.” Childhood brain tumor survivors consider school attendance as part of a normal disease-free life. Social contact and friendships represent their main motivating factors for returning to school. Attitudes and feelings regarding performance, difficulties, and support vary among survivors and change over time. In conclusion, continuity in learning and social contact established before the return facilitate the reintegration process. A comprehensive assessment of their academic and psychosocial functioning should be organized on reentry. Systematic follow-up by parents, school staff, and health professionals throughout the child’s school career is required.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Reintegration into school of childhood brain tumor survivors: a qualitative study using the International Classification of functioning, disability and Health - Children and Youth framework

Purpose: The purpose of this study was to describe experiences of childhood brain tumor survivors (CBTS) and key figures in their environment after returning to school, using the International Classification of Functioning, Disability and Health - Children and Youth framework. Methods: We conducted semi-structured interviews with five children, nine parents, 28 teachers, and 14 health professionals at three predetermined times over a two-year period. A qualitative content analysis was performed by linking meaningful units from transcribed interviews to ICF codes. Results: Children experienced diverse body dysfunctions that could impede school participation, mostly related to knowledge acquisition and application, executive functioning and social life. Support at school and professional aftercare were essential to alleviate the child's difficulties. The teacher's attitude, parental involvement, and practices of collaboration belonging to the child's supportive network further influenced the reintegration process. Also, child-specific factors including emotional reactions to illness, age, and balance between school life and leisure time were considered to affect school readjustment. Conclusions: The International Classification of Functioning, Disability and Health framework is a useful instrument to systematically describe experiences of CBTS and key figures regarding school life, providing a common language to communicate for stakeholders in education and healthcare following the child's return
