A defective gene linked to autism influences how neurons connect and communicate with each other in the brain, according to a study from Washington University School of Medicine in St. Louis. Rodents that lack the gene form too many connections between brain neurons and have difficulty learning.
Children born to mothers who experienced fever, especially multiple fevers, during the second trimester of pregnancy are at increased risk for developing autism spectrum disorder (ASD), a new study suggested.
A new study finds that in addition to autism being more common in males than females, differences in brain structure can also be a factor, regardless of biological sex. It suggests that having a brain with features more commonly found in male brains is linked to higher probability of having autism spectrum disorder.
