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

Taking prenatal multivitamins may reduce the risk of having a child who has autism with intellectual disability, another vaccine-autism link study is being retracted, and schizophrenia sometimes accompanies autism.

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 monkey study suggests facial recognition is not innate, a puzzle piece symbol carries negative connotations, and scientists are using a federal law to snoop on colleagues.

Some drugs used to treat epilepsy may harm children who are exposed to them in the womb or through breast milk.

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.

Following women with autism through pregnancy and beyond may reveal factors that shape the likelihood of autism in their children.

Transcranial treatment may bolster memory in adults with autism, inflammatory molecule may alter an emotional brain region in newborns, and examining ants could yield insights into autism

People who carry risk factors for autism but do not have the condition tend to have slightly fewer children than average, and have them later in life.
