Looking at autism case IQ distributions (CDC ADDM: ~35% with intellectual disability, ~23% borderline) implies a majority of contemporary diagnoses involve impairments that should have been noticed in prior decades, so a large part of the prevalence increase reflects a genuine rise in neurodevelopmental problems rather than only diagnostic relabeling. The author argues the rise began for births in the late 1980s and has accelerated exponentially into the present.
— If valid, this reframes autism from mainly a labeling/administrative issue to a pressing public‑health epidemic with implications for environmental research, service capacity, and prevention policy.

Uses CDC ADDM network statistics (35.2% ID, 23.1% borderline) and administrative prevalence time series to argue >58% of cases would have been clinically obvious in earlier eras, so the magnitude/timing (late‑1980s birth cohorts onward) requires explanation beyond reporting changes.
