Maternal autoantibody–related autism spectrum disorder (MAR ASD) is marked by specific maternal antibodies that react to certain proteins in the fetal brain. Examining the plasma of expecting mothers, researchers found mothers with reactivity to one of the nine MAR ASD patterns were eight times as likely to have a child diagnosed with autism.
Proactive control is not impaired in those on the autism spectrum. Instead, those with ASD implement proactive control in a unique manner.
Autistic children with traditional anxiety had significantly greater amygdala volume than children without ASD. Those with autism-distinct anxiety had significantly lower amygdala volume.
A new PNAS study reveals typically developing children experience neurogenesis in the amygdala as they become adults. However, for those with autism, the amygdala loses neurons as they age.
Using rhesus macaques, researchers have developed a new model of early-stage Alzheimer's disease.
A new study reveals up to 30% of children diagnosed with autism had less severe symptoms at age six than they did at age three. In some cases, children lost their autism diagnoses entirely. Girls are more likely to show a greater reduction in autism symptoms and less of a rise in the severity of symptoms than boys on the autism spectrum.
Two new studies shed light on brain development and changes in ASD. Researchers found the development of white matter tracts in the brain was linked to the severity of autism symptoms. Additionally, larger brain size at age 3 was linked to a larger brain size later in childhood.
Using machine learning, researchers have identified patterns of maternal autoantibodies in the blood plasma of pregnant women that were highly associated with autism and the severity of symptoms in offspring.
Scanning the brains of sleeping toddlers, researchers found the hippocampus is activated as memories for new words are formed. The findings suggest the hippocampus plays an important role in the formation of new word memories.
