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.

The fact that autism seems to affect more boys than girls is often attributed to diagnostic gaps, but the skew remains largely unexplained. Some scientists are turning to basic biology for answers.

Model animals don’t develop the usual behavioral and motor problems when reared in an enclosure containing exercise wheels, toys and treats.

As 2021 comes to a close, Spectrum recaps some of the biggest trends in autism science this year: studies of sex differences, noncoding regions of the genome and points of convergence, as well as efforts to improve screening and participatory research.

These short reports from Spectrum journalists highlight some of the autism-related findings that caught our attention at the meeting this past week.

Compared with a previous mouse strain, a new model better reflects some of the difficulties that people with a rare autism-related syndrome experience, and may help identify biomarkers of the syndrome.

In this edition of Null and Noteworthy, tests of intranasal oxytocin and an Angelman syndrome treatment fail to see results.

The X chromosome holds stronger-than-expected genetic sway over the structure of several brain regions. The genes that may underlie this oversized influence have ties to autism.
