Study finds slightly higher risk of autism diagnosis in areas with more lithium in drinking water, but experts say more research is needed | CNN

Study Finds Slightly Higher Risk of Autism Diagnosis Linked to High Lithium Levels in Tap Water, But More Research Needed.

A new study published in the journal JAMA Pediatrics has found a modest association between exposure to high levels of lithium in tap water and an increased risk of autism spectrum disorder (ASD) in children. The research, which was conducted in Denmark where lithium levels in drinking water are similar to those in US systems, suggests that pregnant women who drank water with higher levels of lithium had a 24-46% higher risk of their child being diagnosed with ASD.

The study, which analyzed data from over 8,800 children born between 2000 and 2013, found that the association was most pronounced among those exposed to the highest levels of lithium. However, experts caution that this does not show a direct link between lithium exposure and autism diagnosis.

"We still don't know what causes autism, and genetics is likely playing a role," said Dr. Beate Ritz, a co-author of the study and professor of neurology at UCLA. "But it's clear that environmental factors can also play a part, and this research highlights the need for more studies on the topic."

The findings have implications for public health policy, as lithium levels in water are not regulated by the US Geological Survey. Dr. David C. Bellinger, a professor of neurology and psychology at Harvard Medical School, noted that "if these associations are valid, we'll need to develop guidelines for lithium in drinking water that protect the entire population."

However, other experts are more cautious, citing the need for further research before drawing conclusions about the relationship between lithium exposure and autism. Dr. Max Wiznitzer, director of the Rainbow Autism Center at University Hospitals Rainbow Babies and Children's Hospital in Cleveland, said "it's an interesting association, but causation is not proven."

The study's findings add to a growing body of evidence suggesting connections between environmental exposures and ASD. Research has also linked autism to exposure to pesticides, air pollution, and phthalates, but these factors have not been shown to be direct causes of the disorder.

In order to fully understand the relationship between lithium exposure and autism, more research is needed. As Dr. Wiznitzer noted, "we're bombarded with environmental stressors in our everyday lives. We need to figure out how to safely navigate them." The study's authors agree, stating that further replication of their findings in other countries will be necessary to establish a causal link between lithium exposure and autism.

omg, this is so concerning ! i mean, we already know there are so many environmental toxins out there that can affect our health, but now it seems like even something as common as tap water might be linked to autism? i'm all for research and figuring out the truth, but at the same time, we gotta take action to protect our kids and communities from these kinds of exposures. lithium levels in drinking water should be regulated ASAP it's just not worth taking any chances, you know? and yeah, genetics probably plays a role too, but environmental factors can't be ignored either

I'm not sure what's more concerning - the fact that high levels of lithium in tap water might be linked to an increased risk of autism or how lax regulations around it are . I mean, think about it, pregnant women are already vulnerable, and adding high levels of lithium to their mix could have unpredictable consequences for their babies . We need more research, no doubt, but shouldn't we also start thinking about safer guidelines for water quality? It's like, how many environmental stressors can our bodies really handle before things start to go wrong?

the more I think about this the more it makes me wonder what we're exposing ourselves to without even realizing it . all these environmental stressors that are being linked to autism, is it really just a coincidence or is there something deeper going on? like, our bodies are designed to be exposed to certain things, but with the advancements in technology and industrialization, we're pushing the boundaries of what's 'safe' for us . the fact that lithium levels aren't regulated by the US Geological Survey is worrying, it just means there's a gap in our knowledge about what's really going on here . we need more research to figure out how to navigate these environmental stressors without harming ourselves or future generations .

I'm totally against this research... I mean, who needs more stress on our environment? Lithium levels are already low enough, right? We're basically telling pregnant women to go ahead and drink water that's gonna make their kids 24-46% more likely to get diagnosed with autism. That's not a risk, that's a reward! And what's next? Are we gonna start giving out extra doses of anxiety meds at birth or something?

And let's be real, the whole "environmental factors" thing is just a fancy way of saying "we don't know what's really going on". We're so scared of admitting that our environment isn't as safe as we think it is, so instead we throw around buzzwords like "autism spectrum disorder" and pretend like we're doing something. Meanwhile, people are still gonna be exposed to all sorts of toxins and stressors, and we're just gonna shrug and say "oh well".

This study is just a waste of time and resources. We should be focusing on the real causes of autism, not just throwing around correlations and risk factors like they're going out of style.

i mean, its kinda crazy thinkin we might wanna lower lithium levels in our tap water cuz it could affect kids with autism. but at the same time, if there is an association, dont we wanna know more? idk about causation here tho, maybe its just a correlation gotta be careful not to jump to conclusions. and what about other factors that might be playin a role in autism? genetics, environmental stuff... we need more research on all this stuff

this is wild fam... so like i was reading this article about some new study and it's saying that high levels of lithium in tap water can increase the risk of autism diagnosis in kids... but here's the thing, experts are all like "we need more research" because they don't know for sure if there's a direct link between lithium and autism.

but what i find suspicious is that this study was done in Denmark where lithium levels in drinking water are similar to those in US systems... so why did they choose Denmark? and what about the fact that the association was most pronounced among those exposed to high levels of lithium?

i'm not saying it's a conspiracy or anything, but it just seems like there might be more to this story than meets the eye. and what about the fact that lithium levels in water are not regulated by the US Geological Survey? that's just weird.

anyway, i guess we'll have to wait and see if further research comes out to confirm or deny these findings... but for now, it's definitely making me think twice about drinking tap water

Lithium levels in tap water? I'm not buying it just yet . I mean, 24-46% higher risk is pretty small potatoes, right? We need more research to figure out if there's even a connection here. And what about the variables - were they controlling for other environmental factors that could be contributing to autism diagnoses? I don't want to dismiss it outright, but we can't just jump to conclusions here . More studies are needed to prove this association and understand how lithium exposure could be linked to autism .

i'm not sure about this study, it seems kinda convenient that the highest risk is among those with highest exposure levels... like what if people are already more prone to autism due to some other factor? shouldn't we be looking at how different groups respond to high lithium levels before jumping to conclusions? also, isn't there a safe threshold for lithium in water? why aren't experts pushing for that regulation yet?

OMG, this is kinda wild ! I'm not surprised though, we've been hearing about toxins in our water for ages . If there's even a slight connection between high lithium levels and autism diagnosis, it's gotta be worth looking into, you know? Like, what are the safe limits for lithium in tap water? Shouldn't we be regulating that or something? Also, I'm low-key freaking out about all these potential environmental stressors affecting our kids' health... we need to take action ASAP!

I'm not sure if it's really that surprising, but a 24-46% higher risk of ASD? That's still pretty low if you ask me... I mean, my kid's got fidgety legs and everything! But seriously, can we even say for sure that it's the lithium levels in tap water? Like, are we ruling out other stuff entirely? I'm not a scientist or anything, but it seems like they're kinda saying "hey, let's look into this" rather than "we've got it figured out". Can't we just do some more research and get to the bottom of it?

omg u guys, i'm like totally concerned about this new study that found a possible link between high lithium levels in tap water and autism . idk if its legit but the stats are def weird - pregnant moms who drank water with high lithium levels had a 24-46% higher risk of their kid gettin diagnosed with ASD . i feel like we need more research before we start freakin out about it tho, esp since we dont know whats causin autism in the first place . its cool that they're lookin into environmental factors though, cuz we do seem to be bombarded with toxic stuff these days . lets hope they get some more data and can figure out what's goin on

lithium levels in tap water might be linked to higher autism diagnosis risk... not sure what to make of this yet . it's like our drinking water is trying to tell us something but we're still not listening . we need more research, obvs . and can we please prioritize finding safe ways for pregnant women to reduce their exposure? that would be a huge relief . also, what's the deal with lithium levels in Denmark being similar to US systems yet they didn't experience the same issue? is it something about water treatment or population dynamics? not trying to be a conspiracy theorist here... just genuinely curious .

So like i was reading this study about tap water and autism and it's kinda cool but also super sketchy? Apparently there's some correlation between drinking water with high levels of lithium and an increased risk of autism in kids... 24-46% higher risk, whoa . But here's the thing, experts are all like "we don't know what causes autism" and genetics is probably playing a role . So yeah, it's possible that environmental factors like tap water can play a part too? Make sense, right?

And now we have to worry about regulating lithium levels in our drinking water? That sounds like a lot of work... . I mean, i'm not saying it's bad or anything, but let's not jump to conclusions here . We need more research, duh! Like, how do we even navigate all these environmental stressors without hurting ourselves? It's like our bodies are trying to handle too much already .

Anyway, gotta keep an eye on this one...

omg I'm literally freaking out about this study!!! so like they found a connection between high lithium levels in tap water and autism diagnoses but its not just that, it's the fact that its been happening for years without anyone knowing or paying attention I mean what if our parents and grandparents had drank this water when they were pregnant and we're all autistic as a result?!?! it gives me chills thinking about it

anyway, I know some experts are saying its not proven yet but like, what even is the point of having guidelines for lithium in drinking water if we don't at least try to figure out if its safe or not? I'm all for more research but seriously, can't they just be proactive about it?!?! and btw, can you imagine if this study was done on a global scale? like what would happen then?!

anywayz, back to the topic at hand. so, its not like we know yet if lithium exposure causes autism or whatever but like, the fact that there's even a connection is kinda scary and also kinda heartbreaking because what about all the autistic people who are already out here suffering from lack of support and understanding?
