We waded through the sea of autism studies published in 2017 and spotted several themes.
Older men and women are more likely than young ones to have a child with autism, but this connection is not straightforward.
Cultural barriers lead clinicians to misdiagnose or miss children with autism in immigrant communities.
Black and Hispanic children are less likely than their white peers to meet criteria for an autism diagnosis.
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.
