Study Finds Modest Link Between High Lithium Levels in Drinking Water and Autism Risk, But Experts Urge Caution.
A recent study published in the journal JAMA Pediatrics has discovered a modest association between high levels of lithium in drinking water and an increased risk of autism spectrum disorder (ASD) in children. The research found that children born to pregnant women exposed to tap water with higher levels of lithium had a 24% to 46% higher risk of ASD diagnosis compared to those with lower exposure.
The study, conducted by researchers in Denmark, analyzed data from over 8,400 cases of ASD and 43,800 controls. The findings suggest that areas with higher levels of lithium in drinking water may have a slightly higher incidence of autism diagnoses. However, experts caution that this association does not necessarily imply a direct causal link between lithium exposure and ASD.
Lithium is an alkali metal commonly used in batteries, grease, air conditioners, and as a treatment for certain mental health disorders. Its levels in US drinking water are not regulated by the federal government. The researchers chose Denmark as their study site due to its relatively low consumption of bottled water.
The study's lead author, Dr. Beate Ritz, emphasized the need for further research to confirm the findings and explore potential causal mechanisms. "Any drinking water contaminants that may affect the developing human brain deserve intense scrutiny," she said in a statement.
While the current study suggests an association between high lithium levels and ASD risk, other research has not found a similar connection. Studies have explored links between environmental exposures such as pesticides, air pollution, and phthalates and ASD, but none of these have identified any direct causal factors.
Experts acknowledge that proving a link between environmental exposure and ASD is challenging due to the complexity of the disorder. Dr. Max Wiznitzer, director of the Rainbow Autism Center, noted that "we are bombarded with a variety of environmental stressors in our everyday lives... We have to figure out how to basically safely navigate them."
The study's findings highlight the need for more research into the potential causes of ASD and the impact of environmental factors on child development. As Dr. Ritz cautioned, "the basic biology of ASD is still not well understood," making it difficult to distinguish causal from spurious associations.
In conclusion, while the recent study found a modest link between high lithium levels in drinking water and autism risk, experts emphasize the need for further research and caution against drawing direct conclusions.

 and honestly its kinda freaking me out thinking about all the lithium in my tap water lol idk what to make of it but its def making me think twice about where my kids play and drink from . i mean we know toxins are bad for us but at least we can control bottled water right? anyway i wanna see more research on this stuff so like scientists can get to the bottom of it

 I'm not surprised to see another link between environmental factors and autism. Growing up, my friends and I would play outside 'til the streetlights came on and never had a single problem. Nowadays, everyone's so worried about their kid's development, it's like they're walking around with a ticking time bomb under their belt.

And yet, the study says there's a link between high levels and autism risk. But what does that really mean? I'm not saying I'd want to live in some random town with tap water that's full of lithium, but at the same time... is it even worth worrying about?

 i'm all for more research, though - we need to know what's safe and what's not. and if there is a link, we should be looking at ways to mitigate it, you know?

 Those researchers should've dug deeper imo  . And it's not like the government's gonna start regulating lithium levels in water anytime soon
. And it's not like the government's gonna start regulating lithium levels in water anytime soon  . I guess it's good that they're saying there's no direct causal link, but still... who knows what other stuff is out there?
