Research has uncovered a mild correlation between lithium levels in drinking water and an increased risk of autism spectrum disorder (ASD) in children born to mothers exposed to higher concentrations. However, experts caution that the findings do not indicate a direct causal link.
According to recent studies, approximately 1 in 36 children in the US is diagnosed with ASD each year. The exact cause of autism remains unknown, with genetics and environmental factors being potential contributors. One study published this year explored cases in the New York-New Jersey area, revealing that ASD diagnosis rates tripled among certain age groups between 2000 and 2016.
Researchers at a Danish university conducted a new study on over 8,800 children born to mothers exposed to varying levels of lithium in drinking water. The team found a modest association between higher lithium exposure and an increased risk of ASD diagnosis. Specifically, the group with the highest exposure had a 46% higher risk compared to those with lower exposure.
However, experts emphasize that the connection is not yet proven, and more research is needed to understand the relationship between lithium levels in drinking water and autism risk. Dr. Beate Ritz, co-author of the study, noted that "any drinking water contaminants that may affect the developing human brain deserve intense scrutiny." She added that further replication of the findings in other countries is necessary.
Lithium levels in water are not regulated in the US, according to the US Geological Survey. The element can be found naturally in food and groundwater, as well as being used in batteries, grease, air conditioners, and the treatment of certain mental health disorders. Previous research on lithium has linked it to improved rates of hospitalization for psychiatric disorders and lower rates of suicide.
While some experts have expressed concerns about potential links between environmental exposures and ASD, others caution that establishing causal relationships is a complex task. Dr. Max Wiznitzer pointed out that studies examining the effects of higher doses of lithium on pregnant individuals have not shown a connection with autism spectrum disorder.
The scientific community emphasizes the need for further research to clarify any associations between lithium exposure and ASD risk. Until then, policymakers must navigate the complexity of potential guidelines for regulating lithium levels in drinking water while balancing competing interests and uncertainties.

 a 46% increase in autism risk just from lithium levels in drinking water? it's like, what even is going on here? i mean i get that more research needs to be done but come on, let's at least try to regulate those things in our water supply already!

 I'm not saying it's definitely gonna cause it but like seriously 46% higher risk is kinda wild right?

 we need more research on this ASAP, esp since lithium levels aren't even regulated in the US

 . But here's the thing: it doesn't mean that drinking tap water with lithium directly causes autism. It just means that if you're exposed to really high levels, they are 46% more likely to get diagnosed.

We need to keep studying and figuring out what causes it so we can help these kids more effectively

. I mean, we already know lithium can affect people with certain mental health disorders, so what else is it going to do to our kids' brains?  And why wasn't this research done sooner? We're already seeing some pretty rough ASD diagnosis rates in the US, and now we might be able to find a link to something as simple (or complicated) as lithium levels in water. I'm all for more research, but I think we need to start taking steps to regulate our drinking water ASAP. It's just not worth the risk

. . It's not good news that 1 in 36 kids is diagnosed with ASD each year, but if we can find ways to reduce the risk, it would be a huge help. I mean, lithium is already used for mental health treatment, so it's weird that we're finding connections between it and autism

 . I mean, think about it - we're already dealing with a serious issue like ASD on one hand, and now we've got lithium in our drinking water that could potentially contribute to it? It's like the more things change, the more they stay the same, you know?
