Autisme: une etude evoque une perturbation du transport du calcium dans le cerveau | L'actualite		04/04/2025
«MONTREAL ...” Un dérèglement du mécanisme de transport du calcium dans le cerveau pourrait être associé à l'autisme et à la déficience intellectuelle, démontrent des travaux effectués à l'Université McGill.Ces conclusions chamboulent une croyance bien implantée chez les neuroscientifiques et pourraient ouvrir la voie à de nouveaux traitements, assure-t-on.«Ã‡a change complètement notre compréhension du fonctionnement du cerveau, a dit le professeur Derek Bowie, de l'Ecole des sciences biomédicales de McGill. On a maintenant une sorte de structure, de « framework », pour comprendre comment fonctionne l'autisme.»Le professeur Bowie et son équipe ont constaté, contrairement à ce que l'on croyait, que des structures cérébrales connues sous le nom de récepteurs AMPA peuvent transporter du calcium, et qu'elles sont même très efficaces à le faire.»...

Auditory environments influence the link between Autistic traits and quality of life | Scientific Reports		28/03/2025
«Abstract Autistic people often report a heightened sensitivity to sound. Yet, research into Autistic people's auditory environments and their impacts on quality of life is limited. We conducted an online survey to understand how auditory environments influence the relationships between Autistic traits and impacts on quality of life (iQoL) due to sound sensitivity. We also sought to determine strategies that Autistic people use to navigate auditory sensitivities in daily life.296 Autistic adults (58.4% women, 15.9% men, 24.3% non-binary+) aged 18-71 years completed the survey comprising a questionnaire with bespoke items measuring auditory experiences in different environments (e.g., noisy vs. quiet) and measures of Autistic traits and iQoL. Our path analyses revealed a significant indirect effect of aversive auditory environments on the relationships between all domains of Autistic traits and iQoL. Notably, the association between non-verbal social communication trait and iQoL was fully mediated by all forms of auditory environments»...

SFARI | Simons Sleep Project Releases Data About Sleep Behaviors and Autism		28/03/2025
«Disrupted sleep is a common occurrence for those with autism, and a new project is helping discover why. The Simons Foundation Autism Research Initiative (SFARI) is pleased to announce the release of data collected from its Simons Sleep Project (SSP), a study aimed at accelerating research into sleep and daily behaviors in individuals with autism. The SSP engaged more than 100 adolescent participants with autism and their non-affected siblings and collected more than 3,000 nights' worth of data.Related ContentSFARI workshop explores sleep challenges in autism spectrum disorder"The SSP is the first-ever study to compile sleep data from adolescents with and without autism over a long period of time," says the study's senior author, Ilan Dinstein, a former senior visiting research scientist at SFARI and a professor at the Ben-Gurion University of the Negev in Israel. "This data was collected in the participants' own homes, helping to ensure that it captures each person's typical sleep experience as closely as possible. It also employed several state-of-the-art technologies for recording critical sleep-related measures that may differ between individuals with and without autism."»...
