Correlation link only at this point. From the abstract:

> Overall state water fluoridation prevalence (not distinguishing between fluoridation types) was also significantly positively correlated with state prevalence of ADHD for all but one year examined. [...] The relationship between fluoride exposure and ADHD warrants future study.

Still, it will be interesting to see what more comes out of this.

After reading the title and the paper's abstract, this seems to me like just one more instance of the many, many statistics that are strongly correlated with overall economic development of a society, and hence strongly correlated with each other without any causal link. In this case, the relevant factors would be "water fluoridation prevalence" and "capacity of doctors to diagnose ADHD", which are both almost certainly correlated with the overall economic status of a society (not of individuals).

It's been a while since I read up on the subject for personal reasons, but wasn't one of the problems with ADHD for a long time that getting accurate numbers was hard because of frequent misdiagnosis (actually just diagnosing a depression instead). Especially, because the symptoms were still considered debatable at that time? So maybe, diagnosis shifted dramatically during that time as well?

It is naive postulation to dismiss the paper for not addressing a variable, when you have not even read the paper to know whether they addressed the variable.

Further, your cursory read of the abstract somehow missed the clause "after controlling for socioeconomic status"
