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.

Tuberous sclerosis complex-associated neuropsychiatric disorders (TAND) are often present but underidentified and undertreated in individuals with tuberous sclerosis complex (TSC). The clinician-completed TAND-Lifetime Checklist (TAND-L) was developed to address this identification and treatment gap. Stakeholder engagement identified the need for a TAND Checklist that can (1) be completed by caregivers or individuals with TSC and (2) quantify TAND difficulties. The aim of this study was to develop a self-report quantified TAND Checklist (TAND-SQ) and conduct feasibility and acceptability testing. This aim was addressed in three phases: (1) development of the TAND-SQ Checklist, (2) feasibility and acceptability testing of the "near-final" TAND-SQ Checklist, and (3) preparation of the final TAND-SQ Checklist. Participants included 23 technical experts from the TAND consortium in all phases and 58 lived experts (caregivers and individuals with TSC) in phase 2. All participants completed a TAND-SQ Checklist and a checklist feedback form. Phase 1 additions to the TAND-SQ, when compared with the TAND-L, included four new items and a quantification rating. Phase 2 showed high ratings for the "near-final" TAND-SQ Checklist on comprehensiveness, clarity, ease of use, and overall acceptability. In phase 3, questions on strengths, strategies, and a TAND Cluster Profile were added. The TAND-SQ Checklist is presented here for use by individuals with TSC and their caregivers. The next steps as part of the TANDem project include internal and external validation of the checklist and linking of TAND Cluster Profiles generated from the checklist to evidence-informed consensus recommendations within a smartphone application.

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.

Objective: To discover short-term changes in perspectives of parents and teachers of childhood brain tumour survivors on school reintegration, in order to reveal similarities and differences between them over time. Methods: Semi-structured interviews were conducted with parents and teachers of five children at the start and the end of a 1-year period following the child’s school re-entry. Results: Thematic analysis of data resulted in three main themes: ‘the child’s performance and wellbeing’, ‘the school’s attitude and approach’ and ‘communication and working together’. Parental concerns about child-specific changes and the school’s approach to the child could either decrease or increase over time. Teachers remained focused on assessing their pupil’s learning potential and finding ways of appropriate support. Their different perspectives on communication and working together became more pronounced. Conclusions: This study emphasizes the importance of clear communication and collaboration, coordinated follow-up and availability of healthcare professionals during the child’s school reintegration.

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.
