Why autism rates seem to rise—and what it means for Thai families and schools
A new wave of research suggests that autism rates are not rising because more children are suddenly developing autism at an unprecedented pace, but because our ability to detect, name, and support these differences has grown dramatically. Large-scale analyses point to decades of improved screening, broader diagnostic criteria, and greater awareness as the primary drivers behind higher reported prevalence. Yet scientists caution that the story is nuanced: a genuine, small rise in some contexts cannot be ruled out, while social and health system factors reshape the numbers we see on every national chart. For Thai families, educators, and health workers, these findings matter because they translate into earlier help, better school inclusion, and more targeted support for children and their caregivers.
