Why does brain development diverge from normal in autism spectrum disorders? (April 17, 2011) -- Rett syndrome, a neurodevelopmental disorder on the autism spectrum, is marked by relatively normal development in infancy followed by a loss of loss of cognitive, social and language skills starting at 12 to 18 months of age.
