A Matter of Age

Children born in the weeks just before cutoff dates for starting school more likely to be diagnosed with ADHD

Could a child’s birthday put them at risk for an ADHD misdiagnosis? The answer appears to be yes, at least among children born in August who start school in states with a Sept. 1 cutoff enrollment date, according to a new study led by Harvard Medical School researchers.

The findings, published Nov. 28 in The New England Journal of Medicine, show that children born in August in those states are 30 percent more likely to receive an ADHD diagnosis, compared with their slightly older peers enrolled in the same grade.
