Studies Suggest Female Brain Has Inherent Protection from Autism

It is well-known that autism affects boys more often than girls. The current ratio is 4 to 1, and is even as high as 8 to 1 at the higher end of the spectrum. While the reason for this gender inequality is currently unknown, scientists are searching for a reason why females are less likely to be diagnosed with the disorder. A recent study at Yale University suggests that the female brain may somehow be inherently protected from developing autism. Researcher Stephen Sanders and his team observed variations in genes and mutations between male and female subjects. They found that girls actually had substantially more high-risk genetic mutations associated with autism than boys, yet they were less likely to develop autistic behaviors. These results imply that female brains may have more inherent protection against developing the disorder than male brains.
