What's the Link Between Theory of Mind and Other Cognitive Abilities - A Co-twin Control Design of Neurodevelopmental Disorders

Navigating Social Waters: Understanding Theory-of-Mind Challenges in Patients with Mesial Temporal Lobe Epilepsy

Background: Temporal lobe epilepsy is a common neurological disease that affects many areas of patients' lives, including social competence. The aim of the study was to assess theory of mind in patients with temporal lobe epilepsy and to investigate the demographic and clinical factors associated with this function. Methods: A total of 65 participants took part in the study, which included 44 patients with epilepsy and 21 demographically matched healthy individuals. The following neuropsychological tests were used to examine theory of mind: the Faux Pas Test, the Hinting Task, the Emotion Comprehension Test, and a cognitive function screen, the Montreal Cognitive Assessment. Results: Patients with epilepsy scored lower on all measures of the theory-of-mind tests. Moreover, in the clinical group, numerous moderate and strong correlations were found between the theory-of-mind tests and education, age at onset of epilepsy, lateralization of epileptic focus, cognitive status, and, to a lesser degree, number of anti-epileptic drugs, frequency of seizures, and age. In contrast, in the control group, significant correlations were found mostly between the theory-of-mind tests and sex, and, to a lesser degree, age. Education and cognitive functioning were not associated. Conclusions: Patients with epilepsy experience difficulties in theory of mind, which may have a negative impact on the quality of their social relationships. The level of theory-of-mind abilities correlates with particular clinical and demographic indicators. Recognizing these issues allows clinicians to implement tailored interventions, potentially improving patients' quality of life.

Risk and resilience factors impacting the mental health and wellbeing of siblings of individuals with neurodevelopmental conditions: A mixed methods systematic review

OBJECTIVE

This pre-registered systematic review synthesised and evaluated the existing literature on self-reported mental health and wellbeing of siblings of individuals with neurodevelopmental conditions (NDCs).

METHODS

From 2437 identified studies published 2000-2022, 81 studies were included: 14 population- or cohort-based, 39 quantitative, 7 mixed method, and 21 qualitative outcome studies.

RESULTS

Seven sibling mental health (any psychiatric disorder, anxiety, depression, bipolar disorder, schizophrenia, internalising and externalising difficulties) and five wellbeing indicators were identified (quality of life, emotional adjustment, social wellbeing, somatic/physical wellbeing, and resilience/growth). Overall, siblings had increased risk of any psychiatric disorder, but they also reported experiences of growth and resilience, primarily in qualitative studies. 41 risk factors and 24 resilience factors associated with these outcomes were identified; the most frequently cited risk factor was symptom severity of the NDC sibling, while the most common resilience factor was adaptive/active coping at the individual sibling level. Studies showed high methodological heterogeneity and 90 different self-report measures were used.

CONCLUSIONS

Sibling mental health indictors are heterogeneous and cumulative risk factors may result in poorer wellbeing. There is a need for consistent reporting of family and sibling characteristics, a strengths-based approach to assessment, and identification of protective and resilience-promoting factors.

Intersectional Stigma for Autistic People at Work: A Compound Adverse Impact Effect on Labor Force Participation and Experiences of Belonging

Background

Little research addresses the experiences of autistic people at work, yet employment prospects remain bleak. The extant literature takes a largely remedial perspective and does not focus on harnessing this population's considerable talents. In global organizational practice, several programs purposefully target autistic people for their abilities. However, preliminary evidence suggests that such programs are inadvertently attracting mainly White males, to the exclusion of other demographics. Therefore, stigma surrounding autism at work remains, creating potential compound adverse impacts by marginalizing identities, including gender, race, ethnicity, sexuality, and socioeconomic status. We explored the intersection of autism with other marginalizing identities in the context of work. The research focused on labor force participation for autistic people and, for those in employment, perceptions of exclusion and inclusion. We compared the aforementioned variables by gender identity, racial identity, sexuality, socioeconomic background, and geographic origin.

Methods

We undertook a global cross-sectional survey, advertised through various social media platforms and promoted directly to relevant organizations. The survey included a range of validated measures as well as demographic information. We analyzed the data with frequencies, cross tabulations, chi-square tests, and non-parametric, group-wise comparisons.

Results

We found preliminary evidence of reduced rates of employment participation by race and geographic location. Females and non-binary people had lower perceptions of inclusion and belonging at work. The perception of accommodation provision had a strong association with inclusion and belonging; more so than incidental provision of flexibility in environment and scheduling not framed as a specific accommodation.

Conclusions

The findings highlight the relational aspects of accommodation and a more universal inclusion perspective. We urge practitioners and researchers to monitor employment participation and levels of inclusion/exclusion using intersectional demographic identification. We appeal for cross-cultural collaboration with academic institutions outside the anglosphere to improve our knowledge of global programs and their impact.

Are Executive Dysfunctions Relevant for the Autism-Specific Cognitive Profile?

Executive functions (EF) have been shown to be important for the understanding of Autism Spectrum Disorder (ASD), but dysfunctions of EF are not autism-specific. The specific role of EF in ASD, its relationship to core autism characteristics, such as mentalizing, needs to be explored. Medline- and PsychINFO databases were searched for studies published between 1990 and 2020 that included measures of EF in ASD and typically developing control persons (TD) in combination with either Theory of Mind (ToM) or Weak Central Coherence (WCC) tasks. A pre-registered meta-analysis and cross-study regression was performed including a total of 42 studies (ASD n = 1,546, TD n = 1,206). Results were reported according to PRISMA guidelines. In all cognitive domains, the ASD group showed significantly reduced performance. Importantly, EF subdomains and ToM were not significantly correlated. This finding rules out a significant association between EF subdomains and ToM and questions the relevance of EF dysfunctions for the autism-specific feature of reduced mentalizing.
