Neuroscience studies reveal shifting brain patterns and hyper-connectivity in autism

New research into autism spectrum disorder highlights how brain activity patterns and connectivity change as children age. A study published in the American Journal of Psychiatry suggests that children with more autistic traits favor brain activity patterns tied to sight and movement before age nine, while those tied to social and emotional processing become more prominent after age 14. This indicates that neurological interventions could potentially be tailored based on a child's age.

Further research published in Autism Research reveals that the brain’s reward center is unusually hyper-connected with other social processing networks in autistic individuals. This hyper-connectivity is linked to specific genetic and chemical markers and correlates with differences in social communication. The findings examine how the four primary subnetworks of the social brain—the reward system, face perception network, theory of mind network, and mirror neuron system—integrate or fail to maintain modular segregation during social interaction.
