Men and women with rheumatoid arthritis, an autoimmune condition, are at increased risk of having a child with autism.

Nongenetic rodent models most relevant to autism tend to be those exposed to environmental agents in the womb or shortly after birth.

A reanalysis of data from more than 2 million children in Sweden suggests inherited genetic factors account for 83 percent of autism risk.

Four large studies published since May arrive at various conclusions about whether exposure to antidepressants in the womb ups autism risk.

Patches of overactive neurons in the brains of mice exposed to inflammation in the womb may lead to autism-like features in the mice.

A re-analysis of data yields an increased estimate for the genetic contribution to autism, how the environment might contribute to autism is hard to pin down, and students on the spectrum describe the benefits of using technology at school.

Watch the complete replay of Dan Kennedy discussing crafting social scenarios to study autism.

Two studies back the link between autism and maternal inflammation, other work weakens worry about antidepressant use in pregnancy, and a harassment scandal rocks a university’s cognitive science department.

Some variants in mitochondrial DNA are more common than others in autism, cognitive therapy reduces anxiety for people on the spectrum, and maternal fever in the third trimester is tied to autism risk.

People with autism aren’t easily surprised, the social camouflage some girls and women with autism use may preclude diagnosis, and autism-related genes are rooted deep in human ancestry.
