The temporary organ may hold clues about the origins of autism and brain development, Anna Penn says — if only researchers would study it.

Given the known link between severe maternal infections and autism, some scientists are investigating whether COVID-19 during pregnancy can affect a child’s neurodevelopment.

Infection during pregnancy can tweak a mouse’s gut microbiome in ways that have lasting effects on her pups’ immune system and increase their chances of gut inflammation, a new study suggests.

Brian Lee has transformed the science of linking prenatal experiences to a child’s chances of having autism; his work taps social skills as well as statistical acumen.

The link between autism and prenatal exposure to an immune response may involve altered levels of immune cells, according to a new study.

The more scientists dig into DNA, the more intricate its contribution to autism seems to be. Here, we unravel the complex genetics of autism.

Certain antibodies may shape neurodevelopment by attaching to and invading new neurons in the brain.

Too little — or too much — of certain substances during pregnancy may increase the odds of having a child with autism. Here we explain what scientists know about these associations.

Newborns with either above- or below-average levels of an immune-system marker, among other differences, have increased odds of being autistic.

Pregnant women’s use of acetaminophen may increase the odds of autism and attention deficit hyperactivity disorder in their children.
