Attachment and Autism Spectrum Disorder (Without Intellectual Disability) During Middle Childhood: In Search of the Missing Piece

Inhibitory dysfunction and social processing difficulties in autism: A comprehensive narrative review

The primary inhibitory neurotransmitter γ-aminobutyric acid (GABA) has a prominent role in regulating neural development and function, with disruption to GABAergic signalling linked to behavioural phenotypes associated with neurodevelopmental disorders, particularly autism. Such neurochemical disruption, likely resulting from diverse genetic and molecular mechanisms, particularly during early development, can subsequently affect the cellular balance of excitation and inhibition in neuronal circuits, which may account for the social processing difficulties observed in autism and related conditions. This comprehensive narrative review integrates diverse streams of research from several disciplines, including molecular neurobiology, genetics, epigenetics, and systems neuroscience. In so doing it aims to elucidate the relevance of inhibitory dysfunction to autism, with specific focus on social processing difficulties that represent a core feature of this disorder. Many of the social processing difficulties experienced in autism have been linked to higher levels of the excitatory neurotransmitter glutamate and/or lower levels of inhibitory GABA. While current therapeutic options for social difficulties in autism are largely limited to behavioural interventions, this review highlights the psychopharmacological studies that explore the utility of GABA modulation in alleviating such difficulties.

Child Attachment Representations and Parenting Stress in Mothers and Fathers of School-Age Children with a Diagnosis of Autism Spectrum Disorder: A Pilot Cross-Sectional Study

Mothers and fathers of autistic children (ASD) tend to report elevated levels of parenting stress. Thus, it is critically important to understand which factors contribute to an imbalance between the perceived demands of parenting and the available psychological resources. To date, little is known about the association between child attachment representations and parenting stress. In this study, we first examined group differences in parenting stress levels based on child diagnosis and parents' gender. Second, we explored the predictive role of child diagnosis, autism severity, and child attachment representations on parenting stress. The study involved 23 school-age children with ASD (IQ > 70), 27 without ASD (7-13 years), and their mothers (n = 50) and fathers (n = 50). Data were collected from 2017 to 2020. Parents completed the Social Responsiveness Scale 2 and the Parenting Stress Index-Short Form, while the children's attachment representations were assessed using the School-age Assessment of Attachment. Parents of children with ASD reported higher stress compared with controls. No differences were found between mothers and fathers. Implicit attachment representations have been found to be associated with parenting stress only in mothers, while the severity of social impairment showed a significant effect on parenting stress in both parents. These findings revealed the potential benefit of adaptive attachment representations not only for children themselves but also for mothers and the family system, suggesting the bidirectional nature of parent-child relationships in the context of ASD. The uniqueness of maternal and paternal parenting experiences should be considered when parenting stress is addressed.

Two Halves of the Same Whole: A Framework to Integrate Autism and Mental Health Services

Given the higher rates of co-occurring mental health issues experienced by autistic people, there is a pressing need to implement an effective framework that integrates autism services with appropriate mental health services. This paper discusses the impact of mental illness on the person with autism and their families, and the current challenges they face when accessing mental health support. A framework for service providers is proposed to support the mental health needs and preferences of autistic people. The paper concludes by highlighting the importance of health professionals utilising mental health interventions appropriate for autistic people, including autism-specific suicide prevention and awareness programs.

Explicit and implicit attachment representations in cognitively able school-age children with autism spectrum disorder: A window to their inner world

The few studies available on quality of attachment in school-age children with autism spectrum disorder (ASD) exclusively used questionnaires assessing explicit attachment representations. Thus, in the current study we assessed both explicit and implicit attachment representations in 23 children with ASD (without intellectual disability), 22 with learning disabilities and 27 with typical development aged from 7 to 13 years. A self-reported measure on the quality of attachment to parents and a semi-structured interview were administered to the children. In addition, a developmental assessment of the child including measures of intelligence and social-communication impairment was conducted. Despite the lack of group differences on explicit attachment representations, we found that children with ASD showed higher rates of at-risk self-protective strategies and psychological trauma compared to the TD group. Children with SLD also showed a high level of at-risk implicit attachment representations than TD, albeit to a lesser extent compared to children with ASD. These results may be related to several factors associated with ASD impairment and developmental pathways, such as the atypical learning process which occur at interpersonal level, the difficulties in social information processing and reflective functioning. Our findings suggested that children with ASD may experience difficulties in the construction of balanced implicit attachment representations. Thus, a more comprehensive assessment of attachment including both implicit and explicit representations is recommended.
