I have no interest in defending fluoride, just to be clear. However, studies in most of the "special sciences" rarely tell us as much as proponents claim.
And, this applies to the OP's cited article as much as the tangential fluoride debate.
Well stated. Interesting that the country with the least occurance of early onset neurodegenerative diseases (India) also does not use Fluoride. Of course someone dies every 3 seconds from traffic accidents there.
