A recent study has uncovered a modest yet intriguing link between the levels of lithium in tap water and an increased risk of autism spectrum disorder (ASD) in children born to pregnant women. The research, published in the journal JAMA Pediatrics, found that as lithium levels in water rose, so did the likelihood of ASD diagnosis.
The study's authors analyzed data from over 8,800 cases of ASD and 43,900 participants who did not have ASD, using a database of people with psychiatric disorders. They discovered that children exposed to higher levels of lithium during pregnancy had a 24-26% increased risk of ASD diagnosis compared to those at the lowest exposure level.
While the researchers acknowledge that their findings do not prove causation between lithium exposure and ASD, they suggest that the association may warrant further investigation. Experts emphasize that more research is needed to fully understand any potential links between environmental exposures and ASD.
The implications of this study are complex, particularly when it comes to public health policy. On one hand, high levels of lithium in drinking water have been linked to improved outcomes for people with psychiatric disorders, such as lower rates of hospitalization and suicide. On the other hand, the presence of even small amounts of lithium in tap water may pose a risk to developing brains.
Lithium is a common contaminant found in some food and groundwater sources, but its levels are not regulated in the US. The Danish study's authors chose Denmark for its low consumption of bottled water, which allowed them to gather data on average exposure levels.
However, other experts point out that any association between lithium and ASD must be treated with caution. Studies have linked ASD to environmental exposures such as pesticides, air pollution, and phthalates, but none of these factors have been definitively proven as a direct cause of the disorder.
The complexity of this issue raises important questions about how to safely navigate everyday life while minimizing exposure to potential environmental stressors. As Dr. Max Wiznitzer, director of the Rainbow Autism Center, notes, "we're bombarded with various environmental stressors; we need to figure out which ones are truly causally associated and how to handle them."

. I mean, 24-26% is a pretty significant increase in risk for ASD diagnosis. You gotta wonder if it's just a coincidence or if there's really something going on here. And what's crazy is that we're not even regulating lithium levels in tap water like they do in other countries... like Denmark 
. It's all about finding that balance, you know? How much lithium is safe and how much is too much? It feels like a pretty complex puzzle to figure out 
.
I was reading this study online and it's wild to think that even small amounts of lithium in tap water can increase the risk of autism spectrum disorder in kids 
. I mean, we all know lithium is good for mental health or so they say 
but what if it's actually bad for our brains? 
. The experts are saying that more research needs to be done and I'm like "yaaas please don't wanna be one of those people who gets diagnosed with ASD 
".
I mean, I'm not saying it can't be a coincidence or anything, but you gotta wonder...
lithium in tap water linked to autism risk 
24-26% increased risk for kids exposed during pregnancy 
more research needed for sure 
but what about all the pesticides and air pollution stuff too? 
how do we know which ones are bad news? 
so let's just say be mindful of what you drink 
and maybe get a water filter or something 
I mean, 24-26% increased risk is still kinda low imo. like, what's a safe threshold for lithium exposure? can we even trust the data from Denmark? aren't they just looking at correlations here? and what about all those other environmental stressors that are linked to ASD? shouldn't we be focusing on addressing those first? I'm not saying we should panic or anything, but let's take a step back and think about this.
I'm just worried that we'll find out some other common contaminant is causing harm to our kids and we won't even know until it's too late. 
Can we just go back to the good old days when things were simpler? 
.
.
i wonder if this study would've looked different if they'd analyzed data from countries with stricter water regulations... would be interesting to see some stats on that. also, why are there so many unknowns around this whole thing? like, what's the threshold for 'safe' lithium levels? and how do we know which other environmental factors might actually cause autism? 
.
.
. But at the same time, I'm all for being proactive and figuring out what's safe and what's not 
. Just saying 
Anyway, more research is always a good thing, but maybe we should be looking into ways to regulate lithium levels in water too?
But at the same time, I feel like we need to be aware of what we're exposing our kids to, you know?
