Autism Severity Showed Up in a Shared ADHD Connectome TL;DR: In 166 verbal children diagnosed with either autism or ADHD without autism, stronger resting-state coupling between the left middle frontal gyrus and posterior cingulate cortex tracked clinician-rated autism severity across both diagnoses, while ADHD symptom ratings showed no comparable brain-wide signal. Key Findings 166 low-motion …
Astrocyte BMP Suppression Eased Fragile X Signals TL;DR: In a fragile X mouse model, suppressing BMP signaling specifically in astrocytes reduced sound-triggered seizure severity and partially restored synaptic activity in the auditory cortex, a sound-processing region relevant to sensory over-responsiveness. Key Findings BMP signaling was elevated in fragile X astrocytes: The study focused on bone …
A Visual Autism Subtype Left a Fusiform Lipid Signature TL;DR: A Molecular Psychiatry study suggests that autistic children with atypical visual processing carry a distinct fusiform gyrus lipid-myelin signature, tied to low ceruloplasmin and strong MRI-based subtype discrimination. Key Findings Fusiform subtype emerged in 288 children: The study included 90 autistic children with atypical visual …
Nitric Oxide’s Hidden Link to Autism Behavior TL;DR: A chemical messenger called nitric oxide triggers protein damage that sends the mTOR pathway into overdrive in autism-related mouse models, driving social deficits and repetitive behaviors—and blocking this mechanism reverses both the molecular dysfunction and autistic-like behaviors. Autism spectrum disorder involves dozens of genetic variants, yet many …
A study found a strong link between mitochondrial disorders and conditions like autism, ADHD, and various psychiatric issues. Highlights: Common Link: Mitochondrial disorders are frequently found in people with autism, ADHD, and intellectual disabilities. ASD Emphasis: Most research focused on autism, suggesting it might be more strongly linked to mitochondrial issues or simply better funded. …
A study reported significant causal relationships between specific immune cell subtypes and autism spectrum disorder (ASD), highlighting 26 genetic correlations and potential biomarkers for early detection and treatment. Highlights: Significant Genetic Correlations: The study identifies 26 potential correlations between genetic predispositions in immune cell types (immunophenotypes) and the risk of developing ASD. Bi-Directional Analysis Results: …
A study found that certain genetic variations in the oxytocin receptor gene (OXTR) were associated with different aspects of social understanding abilities in children with and without autism. Highlights: In typically developing children, one genetic variation (rs2268498) was linked to better verbal social understanding skills. In children with autism, a different genetic variation (rs53576) was …
Leptin levels are significantly increased in children with autism spectrum disorder (ASD) compared to healthy controls, suggesting a potential role in ASD pathology. Highlights: Leptin Levels: Children with ASD have significantly higher serum leptin levels compared to healthy controls, as confirmed by both individual study results (p=0.0319) and meta-analysis (p<0.001). Progranulin Reduction: In addition to …
Autism spectrum disorder (ASD) is a complex condition characterized by challenges in social communication and repetitive behaviors. One aspect that contributes to the heterogeneity seen across the autism spectrum is differences in intelligence and cognitive abilities. Recent research is shining new light on the intelligence profiles of individuals with ASD, showing a shift away from …
Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by social communication deficits and repetitive behaviors. The causes are complex, involving genetic and environmental factors that affect brain development. Growing evidence implicates immune system abnormalities and neuroinflammation in ASD. Galectin-1 and galectin-3 are proteins that regulate immune responses and inflammation. A new study found significantly …
