Dr. David Rabiner offers a helpful summary of trends in ADHD diagnoses.
The short version: rates of diagnosis continue to increase.
The longer version: depending how you analyze the categories, you get very different results. For children younger than 5, the rates are — in fact — falling. For adults over 65, however, the rate rose 348% from 2008-9 to 2012-13.
(That is not a typo: 348%).
One important point as you review these data: percentages are interesting, but so too are the absolute numbers. Diagnoses among those over 65 can increase so much as a percentage because the absolute numbers are relatively low.
By the way: analysis by gender shows an interesting pattern. Among adults, both diagnosis and medication are increasing faster for men than women. Among children, however, that pattern is reversed.
