New Study Links Autism to Drinking Water Contaminants, But Experts Warn Against Jumping Conclusions
A recent study published in the journal JAMA Pediatrics has found a modest association between autism spectrum disorder (ASD) and lithium levels in drinking water. However, experts caution that this association does not necessarily mean that exposure to lithium leads directly to an increased risk of ASD.
The researchers analyzed data from over 8,000 children born between 2000 and 2013 in Denmark, where the level of lithium in drinking water is similar to that found in American systems. They found that as lithium levels in water increased, so did the risk of ASD diagnosis among children exposed during pregnancy. Specifically, children exposed to the second and third highest levels of lithium had a 24% to 26% higher risk of ASD diagnosed, while those with the highest exposure level had a 46% higher risk.
However, experts say that this association is not conclusive evidence, and more research is needed to confirm these findings. Dr. Beate Ritz, a study co-author, emphasized that "the research can't show that lithium exposure leads directly to an autism diagnosis." She noted that the study would need to be replicated in other countries to look for similar connections.
The implications of this finding are complex and require further scrutiny. Lithium levels in water have also been linked to health benefits, such as lower rates of hospitalization for psychiatric disorders and suicide. However, Dr. David C. Bellinger warned that "it will be difficult to distinguish causal from spurious associations" until the basic biology of ASD is better understood.
Other researchers point out that connections between environmental exposures and ASD are often difficult to prove. Studies have suggested links between ASD and exposure to pesticides, air pollution, and phthalates, but none have identified these factors as a direct cause of the disorder.
The study's findings highlight the need for further research on the potential effects of drinking water contaminants on human health. Dr. Max Wiznitzer, director of the Rainbow Autism Center, noted that "it's an interesting association, but causation is definitely not proven." He emphasized that "we have to see if there's a viable and biologically plausible mechanism by which a small amount of lithium in the water supply can somehow do this."
Ultimately, more research is needed to determine whether exposure to lithium in drinking water is associated with an increased risk of ASD. Until then, experts urge caution against drawing conclusions based on these findings alone.

i mean, our drinking water has all these chemicals and stuff in it already, so why not lithium too?! 
and don't even get me started on how hard it must be to figure out whether the chemicals cause autism or if there's another factor at play... like, my brain just can't even handle this much info lol 
so its like when we think we found a connection between two things but before we jump to conclusions, there's gotta be more digging done 
first we gotta know how the pieces fit together, not just that they're sitting next to each other in the same space. and sometimes it takes a lot of research and testing to figure out if its cause or effect 
. What if this lithium thing is just a symptom of something bigger? Like, what if our water supply is being manipulated by some unknown entity? 
tbh, it sounds like they just need more research on the whole thing. and btw what if lithium levels in water actually do have health benefits? 
. They're saying that the association is pretty strong, especially for kids exposed during pregnancy, but that doesn't necessarily mean that lithium is directly causing autism 
And scientists are all like "we need to do more research" and "let's replicate this study in other countries". I'm not saying it's a total waste of time or anything 
. But at the same time, we gotta be careful not to jump to conclusions here 
.
. Maybe what we need is more research that actually gets to the bottom of things 
. I mean, think about all the chemicals we're exposed to in our daily lives without even realizing it. Pesticides, air pollution, phthalates... they're all linked to some health issues, right?
