Brain scans reveal two distinct types of autism

Researchers have discovered that autism may actually consist of at least two distinct biological subtypes, identified through brain scans of nearly 1,000 individuals and genetically engineered mouse models. These subtypes are marked by "hyperconnectivity," where brain regions communicate excessively, and "hypoconnectivity," where communication is reduced. This finding is significant as it could lead to more tailored treatments and a deeper understanding of the neurological underpinnings of autism, potentially improving diagnosis and intervention strategies.
