Autism Polygenic Scores Predicted Lower Brain Neurite Density in 36,000 People

TL;DR: A 2025 Molecular Psychiatry study of more than 36,000 people found that higher autism polygenic risk was associated with lower MRI-derived neurite density, a measure of neural-fiber packing, across cortex and white matter in both children and adults. Key Findings Higher autism polygenic score predicted lower neurite density: Across over 36,000 individuals, a robust …
