Study reports girls and boys show similar rates of concern for ASD and identifies several biases contributing to the inflated sex ratio for autism diagnosis. The findings could help with the early identification of girls on the autism spectrum.
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.
Exposure to the opioid fentanyl induces autism-like behaviors in mice by activating mu-opioid receptors in the anterior cingulate cortex.
Valproic acid (VPA), an anti-convulsant medication, can cause birth defects when taken during pregnancy. Researchers identified a molecule called p19Arf that appears to be responsible for VPA's induced senescence in neuroepithelial cells. When exposed to VPA, mice lacking p19Arf did not experience gene expression alterations associated with ASD.
Drumming for 90 minutes per week helps adolescents with ASD to overcome hyperactivity and attention deficits. Learning drumming patterns also tunes brain connectivity in areas associated with inhibitory control and self regulation.
A new study will explore how psilocybin affects different networks and serotonin function in the brains of autistic adults.
Different symptoms of ASD can affect different brain regions and neuroanatomy. AI technology allowed researchers to detect brain differences on an individual level in those with ASD.
Children diagnosed with ASD at 24 months had differences in visual processing areas of the brain which were apparent at six months of age, a new study reports.
