While recorded prevalence and reported case numbers of autism spectrum disorder have risen dramatically, researchers and epidemiologists remain divided on how much of this increase represents a genuine epidemiological rise versus improved ascertainment, expanded diagnostic criteria, and diagnostic substitution.
Notes cross-national ASD variations but states prevalence remained relatively stable in some areas, attributing variations partly to diagnostic capacity.
