The rise in autism diagnoses is largely attributed to increased awareness, broader diagnostic criteria, and improved detection rather than a true increase in the biological incidence of the condition.

Research suggests that societal and medical factors, rather than biological changes, are driving the apparent increase in autism prevalence.
