Researchers from Princeton University, the Simons Foundation, and the Princeton Neuroscience Institute have identified four biologically and clinically distinct subtypes of autism spectrum disorder (ASD). This classification is based on unique genetic patterns and developmental trajectories associated with each subtype. The findings, which represent a significant advancement in understanding autism, were achieved through computational modeling and artificial intelligence techniques. This development is expected to enhance precision diagnosis and enable more personalized care for individuals with ASD.
