The nation needs to build capacity to support the roughly 20 percent of children in Australia who have developmental delay.

The director of the University of Pittsburgh’s Autism Center of Excellence talks about her new work investigating suicidality in autistic adults.

Children with congenital heart disease have an increased likelihood of autism. Why?

The largest analysis of human samples to date, plus work in mice and zebrafish, detail the gene KMT5B’s role in brain development.

The most comprehensive study of neurodevelopmental conditions in Kenya and South Africa ever conducted shares preliminary results and lessons.

In light of growing evidence that motor challenges are common among people with autism, we asked five researchers how these problems fit into the definition of the condition.

Shifts in diagnostic criteria have only added to the condition’s bedeviling heterogeneity, an analysis of smiling, sitting, walking and other early milestones in more than 17,000 autistic children reveals.

Different combinations of common, rare, inherited and spontaneous mutations may explain why traits vary so widely among autistic people.

Sleep problems may contribute to or derive from autism traits — or both. After decades of work, researchers are beginning to uncover the biological connections between the two conditions, revealing new paths to potential treatments.

Mutations in the autism-linked gene PAX5 underlie a range of traits, including developmental delay, intellectual disability, seizures and autism.
