Brain scans reveal two distinct autism subtypes with different underlying biology

MedicalXpress | мая 29, 2026

An international research team led by Istituto Italiano di Tecnologia (IIT-Italian Institute of Technology) in Rovereto (Trento, Italy) and the Child Mind Institute in New York (U.S.), and in collaboration with researchers from the University of Trento, has shown that it is possible to identify at least two distinct subtypes of autism, defined by their patterns of brain connectivity. In the "hyperconnectivity" subtype, brain areas communicate more than usual; in the "hypoconnectivity" subtype, communication between brain areas is reduced.
