Thanks a lot for your feedback. In the meta-analysis from Lancet ADHD is raised as an issue. Then again I wouldn't expect the Chinese to use the exact term since this diagnosis is viral mostly in the US and slowly gaining popularity in the rest of the world. Again, many thanks!

Here you can view it if you have access to the lancet. I personally don't.
(Please also take a look at my other reply providing a link to the original paper they refer to)
I believe this latest article I read cites this older one. http://www.medscape.com/viewarticle/772254
you can view it here in total
I would have to read the article. Can you provide a link to it?
But, I would tend to doubt very much the connection.
This study was only done in China and most of it was in very poor areas of China.
I saw no mention of any link to ADHD.
The only result was a link to lower IQ scores. And even the study discussion said that, "The estimated decrease in average IQ associated with fluoride exposure based on our analysis may seem small and may be within the measurement error of IQ testing." Furthermore, they were not able to factor out the effect of lead (which has a known effect on IQ). "Although official reports of lead concentrations in the study villages in China were not available, some studies reported high percentage (95–100%) of low lead exposure (less than the standard of 0.01mg/L) in drinking-water samples in villages from several study provinces (Bi et al. 2010; Peng et al. 2008; Sun 2010)."
Since the concentrations studied were a great deal higher then any allowed in the US. But more importantly, there really were a lot of holes in the study (which the authors admitted).
This is not a study that I would worry about.
But, it was interesting reading. Thanks for the link!
