Children diagnosed with autism at the age of two had substantially greater amounts of extra axial cerebrospinal fluid at 6 and 12 months. Additionally, the level of increased CSF at 6 months could be correlated with the severity of autism symptoms displayed at 2 years, a new study reports.
Researchers have identified a correlation between brain stem volume and aggressive behavior in children with autism. Smaller brain stems appear to be associated with an increased likelihood of aggression.
A new study reports neurotypical male brain anatomy is associated with a higher risk of ASD, and biological females with more typical male brain anatomy are three times more likely to be diagnosed with ASD.
