Research on the Molecular Mechanism of Cognitive Differences Between Williams Syndrome and Autism Spectrum Disorder

Williams Syndrome (WS) is a rare neurodevelopmental disorder, usually caused by microdeletions of approximately 26 genes in the long arm (7q11.23) region of chromosome 7. Children with this syndrome often exhibit distinctive facial features, mild to moderate intellectual disability, impaired spatial cognition, pronounced social extraversion, and relatively reserved language-expression characteristics. Although individuals with WS often demonstrate strong social interest and prosocial behaviors, significant deficiencies in abstract thinking, executive function, and visuospatial ability are frequently observed. At present, treatment for WS mainly focuses on behavioral intervention and educational rehabilitation, and clear molecular or pharmacological treatment methods remain limited. Due to the "opposite but related" social-cognitive profile observed in comparison with autism spectrum disorder, in-depth exploration of neural and molecular mechanisms underlying these differences has substantial scientific significance for understanding the biological basis of social-cognitive impairment.

CFT Guided Self-help Intervention: Parents of Autistic Children

This research will aim to test how practical, achievable and effective a brief, guided, self-help compassion focused intervention is for parents of autistic children aged 6-17 years old. The demands of parenting can be rewarding but also challenging, and it is known that parents of autistic children experience additional pressures. As a result of this, parents of autistic children may be more likely to experience increased stress, anxiety, low mood and lower quality of life, compared to those parenting children who are not autistic. There has been only a small amount of research so far regarding whether interventions that focus on building compassion, would be beneficial to parents of autistic children. The purpose of this study is to test whether a short, self-guided compassion-focused intervention is practical, achievable and effective for parents of autistic children. The intervention is based on Compassion Focused Therapy (CFT) and involves reading workbook material and listening to audio tracks. There will also be some questionnaires to complete and 30-minute weekly support calls with the lead researcher. This intervention was adapted previously, from an intervention for parents in general, to be more suitable and focused on the needs of parents of autistic children. This study will be the first time the adapted intervention has been used by parents. The intervention will be tested by 6-8 parents and will be about 13 weeks long. We will collect some demographic data at the start of the study, and there will be the opportunity to complete an evaluation questionnaire.

Role of the Gut Vascular Barrier and Microbiota in Autism Spectrum Disorders

Recent research links gut microbiota alterations to Autism Spectrum Disorders (ASD), a neurobiological condition with multifactorial bases. In some ASD patients, altered gut flora and increased intestinal permeability are observed, influencing the central nervous system's development and function. Chronic gastrointestinal (GI) symptoms are commonly associated with ASD and correlate with its severity. This non-pharmacological interventional clinical study aims to investigate the role of gut microbiota on ASD and the effectiveness of postbiotic-based dietary supplements in children aged 3-8 years old. Gastrointestinal symptoms, behavioral profile and analysis of intestinal metagenomic and metabolomic profiles will be assessed before and after one-month treatment. The results of the study could enhance understanding of non-pharmacological therapeutic approaches in ASD and improve clinical management strategies and the behavioural functioning for children with ASD.

Follow-up of Adolescents With Autism and Psychotic Symptoms - Psychiatric Co-morbidity and Functional Impairment.

Purpose: To describe level of function, psychotic and psychiatric symptoms in a 10-year follow up of individuals with autism and psychotic symptoms. Method: A case-control study based on a cohort of 48 teenagers with autism established 2013. In the original study, 22 participant reported psychotic symptom in self-evaluation questionnaires design for early detection. We aim to recruit these individuals and controls from the same cohort without psychotic symptoms. Data will be collected from self-rating scales, clinical evaluation including semi-structured interviews and healthcare journals. The study is primarily descriptive, with group comparison by non-parametric method.

Piloting the Competence in Romance and Understanding Sexual Health Curriculum

The goal of this clinical trial is to learn whether the CRUSH curriculum is possible (feasible), whether it fits the needs of the adults it is designed for (acceptable), and shows initial signs of being helpful (efficacious). CRUSH is a group-based behavioral intervention plus 1-1 coaching designed to provide sexual education and improve the skills of autistic adults for intimate relationships. The main goals of the project are to: * Evaluate the feasibility and acceptability of the CRUSH curriculum in the context of a clinical trial with a waitlist control condition. * Initial exploration of how the CRUSH curriculum works and whether it is helpful. Participants will complete: * A screening call. * Confirmation of clinical characteristics (autism features, language ability, cognitive ability). * 3 visits to assess knowledge and behaviors related to dating and sexual health at each point throughout the training curriculum (before beginning, midway, and after finishing). * 20 sessions of the CRUSH curriculum plus 1-1 coaching sessions. After each session, provide feedback about the session.

Using Virtual Reality to Improve Emotion Understanding in Children With Autism

Autism Spectrum Disorders (ASD) are neurodevelopmental conditions characterized by difficulties in social interaction, communication, and in understanding one's own and others' mental and emotional states. In particular, skills related to the recognition, understanding, and regulation of emotions represent a significant area of vulnerability in children with high-functioning ASD, with important consequences for social and relational functioning. The present study aims to evaluate the effectiveness of an intervention protocol designed to enhance socio-emotional understanding, with a specific focus on the recognition of basic and complex emotions, the expansion of emotional vocabulary, the association between situations, thoughts, and emotions, and the differentiation between thoughts and emotions. Furthermore, the study seeks to investigate the role of immersive technology (Oculus) as a potential facilitator of emotional learning compared to a traditional intervention approach. The sample will consist of children with a diagnosis of high-functioning ASD, aged between 7 and 10 years, with sentence-level language abilities, the capacity to narrate non-present events, and an intellectual quotient above 80 (assessed using the Griffiths Scales or the WISC-IV). Participants will be divided into two groups: an experimental group (OCULUS), which will receive the intervention mediated by the use of Oculus technology, and a control group which will undergo the same protocol without technological support.

How Virtual Reality Can Help Neurodivergent Children Improve Their Attention

The goal of this study is to determine whether playing a virtual reality (VR) game can help neurodivergent children pay attention for extended periods. The study includes children ages 9 to 18 who have autism, ADHD, learning differences, or movement coordination challenges. The program lasts for 6 weeks. During this period, children will play a VR game twice per week, with each session lasting 25 minutes.

GENES AND AUTISM - IPSC

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social interaction and verbal and non-verbal communication (DSM-5, 2013), affecting approximately 2% of the general population. In 5 to 40% of cases, genetic factors are identified as the cause of these disorders, with prevalence depending on the technique used (exomes and/or SNP arrays) and the associated intellectual deficit. In the majority of cases, the aetiology remains unknown. Studies of microdeletions/microduplications (copy number variants) or Whole Exome Sequencing and Whole Genome Sequencing (Single Nucleotide Variants) show the involvement of numerous genes in the predisposition to autism. ASD remains a genetically heterogeneous disorder, as more than 250 genes have been associated with ASD to date. The main objective of the project is to continue identifying genetic factors, and also to understand the biological mechanisms involved in the emergence of autistic symptoms. Identifying biological pathways is an essential step in developing new therapeutic strategies. In addition, one of the major challenges of this study is to better understand the phenotype/genotype relationships in ASD. This requires in-depth knowledge of the phenotypic characteristics of ASD participants and their families, as well as neurotypical populations. This study combines the scientific expertise of researchers specializing in molecular biology, phenotypic exploration (clinical, cognitive, MRI, EEG, biochemistry, immunology), and the use of pre-therapeutic cellular models (iPSCs, neural precursors, organoids). The objectif of this work is the identification of numerous genes associated with ASD and involved in synaptic formation and regulation: NLGN3-4, SHANK1 and SHANK3, CNTN-6, and CNTNAP4. This work was combined with in-depth phenotypic explorations of ASD participants and their relatives. It has made it possible to clarify the neuroanatomical characteristics of ASD participants and their genetic substrate, as well as the underlying cognitive processes. All of this work opens up new prospects for identifying new therapeutic targets using preclinical cell models (IPS, neural progenitors, organoids) developed in particular by I-Stem and Human Technopole.

Impact and Determinants of Success of a Mobile Multidisciplinary Intervention System Specialized in Pain Management for Patients With Moderate to Severe Intellectual Development Disorder, Isolated or Associated With an ASD or Multiple Disability

Pain is described by patients with a Neurodevelopmental Disorder (NDD), including Autism Spectrum Disorder (ASD), Intellectual Development Disorder (IDD) or multiple disabilities, and the family as one of the main associated disorders; its management is also one of the main concerns of families and professionals. At present, there is no validated and tested pain management system in populations facing complex pain situations. In response to the lack of a pain management services, a multi-disciplinary mobile team was set up in September 2022 at the Brest University Hospital (Mobile Pain Handicap Team Intellectual Disability 0-25 years; MoDIDol). This team offers a specific protocol for the assessment and management of pain that takes into account the social and family environment, the living context and the clinical characteristics of patients (children, adolescents and young adults (0-25 years) with IDD, ASD or multiple disabilities). The team includes at least one paediatrician specialising in the assessment and treatment of pain and a nurse, and travels to patients' usual living environments.

NTI164 in Autism Spectrum Disorder

This is a double-blind, randomised, placebo-controlled study investigating the efficacy of a full-spectrum medicinal cannabis plant extract on core and associated ASD symptoms over placebo. Participants will be randomly allocated to either NTI164 or placebo at a 1:1 ratio and blood samples will be collected and surveys completed at baseline and Week 16. This study will expand efficacy and safety data of NTI164 and provide additional mechanism of action data of NTI164 in this patient cohort.

The Intervention of Lactobacillus Plantarum Probiotics in Adult Autistic Spectrum Disorders

This is a qualitative and quantitative mixed-methods, open-label study, will involve 12 participants and their caregivers. Participants will also undergo blood exams and gait analysis, while caregivers will complete qualitative interviews and quantitative questionnaires on autistic symptoms, stress, anxiety, and quality of life. After the baseline assessments, participants will receive Lactobacillus plantarum for 8 weeks, followed by further evaluations at end point.

Using Technologies to Promote HEalthy Lifestyles in Adolescents With Intellectual Disabilities

IDHEApp will implement various educational technology tools and work with the families, teachers and caregivers to increase physical activity (PA) and improve healthy eating. Due to the current COVID-19 pandemic restrictions, the use of innovative digital technology can contribute not just to distance learning but also to support families and students in remote. However, both healthy habits and technologies are insufficiently addressed in the population with IDD. These needs are in line with the following objectives of the Erasmus+ programme: a) Inclusion and diversity in all fields of education, training, youth and sport; b) Addressing digital transformation through development of digital readiness, resilience and capacity, and c) Encouraging the participation in sport and physical activity. Educators will find innovative possibilities and the right instruments that will enable them to fulfil their potential through innovative online education \& learning \& training skills module for lifestyle promotion and others available on the app. Furthermore, mentors and others health professionals (e.g., nursing etc.) will be equipped with knowledge and skills on how to use the app to teach practical skills for PA enhancement in an evidence-based way. Consequently, this project will contribute to \[specific objectives - SO\]: \- Raise awareness of the importance of healthy and active living among young Europeans with intellectual disabilities. Different workshops and bigger events (i.e., international conference), together with the involvement of numerous participants from the institutions of this consortium will be ensured. Further, a sensitized community will participate through the social networks and the website itself, in the proposed activities. \- Provide digital resources and tools to the partner entities of the exchange to improve lifestyle of young people with intellectual disabilities. Best Practices to provide high quality, inclusive digital health education with the best educational technology tools and methodology. A website, a mobile app and different electronic guidelines will be delivered. \- Analyze the current state of use and acceptance of technologies as support in the management of health in adolescent with intellectual disabilities.

The Effectiveness of a Parent Training Program for Children With Autism Spectrum Disorder and High-Risk Infants: A Case-Control Study

The aim of this study is to evaluate the effectiveness of a parent training program on the severity of autism-related symptoms in two groups: (1) infants under the age of 2 who show early signs of autism, and (2) children aged 2 to 5 years who have been diagnosed with Autism Spectrum Disorder (ASD). The study also aims to assess the program's impact on the quality of life and stress levels of the children's parents or caregivers. The study will include children aged 0 to 5 years who are either considered at risk for autism or have an ASD diagnosis, along with their caregivers. A total of 250 participants are expected to enroll in the study. Informed consent will be obtained from all parents or caregivers before participation. After consent, the 250 children will be randomly assigned to one of two groups: Group A: Parent Training Program + Routine Care Group B: Routine Care Only While Group B will receive standard treatments such as education and psychotherapy and a single psychoeducational session about autism and its treatment, Group A will receive the same routine care plus the structured Parent Training Program. Children in both groups will be assessed before the intervention begins and again after 12 weeks. Evaluations will be conducted with the support of professionals using standardized tools. Caregivers will complete a background information form with the help of the research team. To assess symptom severity, the Modified Checklist for Autism in Toddlers (M-CHAT), the Childhood Autism Rating Scale (CARS), and the Clinical Global Impression Scale (CGI) will be administered by clinicians. General developmental levels will be evaluated using screening tools such as the Denver Developmental Screening Test or AGTE. Caregivers will also complete the Quality of Life in Autism-Parent Version and the Parenting Stress Index.

Rural Autistic Individuals - Supporting Expression

This research study investigates how hand gestures can support language comprehension and communication skills of hearing speaking, non-speaking, and/or minimally verbal individuals with Autism Spectrum Disorders (ASD), who are especially disadvantaged by the lack of accessible services in their rural communities. Individuals with other cognitive profiles, including Developmental Language Disorder (DLD), ADHD, Dyslexia, and others are welcome too. The study uses methods of eye tracking and recording of brain activity to understand how hand gestures adapted from signs from American Sign Language, such as \[cry\], can promote successful understanding of words like "cry". The overarching goal is to help families effectively utilize gestures to support communication with their children.
