	Autism study reveals shared brain cell changes during early development Hundreds of genes have been linked to autism, yet the precise molecular and cellular mechanisms behind it remain largely unclear.

	Maternal blood test reveals prenatal methylation clues linked to autism risk Researchers found that maternal plasma cell-free DNA methylation patterns in late pregnancy were associated with later autism diagnosis and maternal obesity in a high-likelihood ASD cohort. The findings suggest cfDNA may offer a minimally invasive way to study prenatal epigenetic changes linked to neurodevelopmental risk, but larger validation studies are needed.

			Scientists identify unique receptor that accelerates early neuron growth Cells have surface receptors that couple to proteins and other molecules to initiate or inhibit certain behaviors.

			Zebrafish study links altered neuronal genes to hyperarousal states The altered presence of tiny fragments of neuronal genes, called microexons, causes hyperarousal in zebrafish. This is the main conclusion of an international study led by the Pompeu Fabra University (UPF) and the Centre for Genomic Regulation (CRG).

			Brainstem neurons found to control attention by suppressing distractions Neurons tucked away in an ancient part of the brain control the ability to pay attention by suppressing distractions and directing focus.

	Longer breastfeeding links to fewer ADHD symptoms in children Longer durations of full breastfeeding are linked to fewer ADHD symptoms in children, suggesting early feeding patterns may influence neurodevelopment.

	Blueberries may boost children's memory and mood Research suggests blueberry compounds could enhance mood and cognitive function in children, yet stronger evidence is required for clinical recommendations.

	Dogs could transform the future of autism drug development For thirty years the search for autism medicines has hit the same wall, and a new peer-reviewed Perspective in Genomic Psychiatry suggests that the way around it has been sleeping at our feet the entire time.
