Study Finds Slight Connection Between High Lithium Levels in Drinking Water and Autism Diagnosis in Children
A recent study published in the journal JAMA Pediatrics has found a moderate link between elevated levels of lithium in drinking water and an increased risk of autism spectrum disorder (ASD) diagnosis in children. However, experts caution that this association does not necessarily prove a direct causal relationship.
According to the research, which focused on Denmark, where lithium levels in drinking water are similar to those found in US systems, pregnant women who were exposed to higher concentrations of lithium had a slightly increased risk of having a child diagnosed with ASD. Specifically, children born to mothers whose exposure levels fell within the second and third highest quartiles had a 24% to 26% higher risk of being diagnosed with ASD.
However, study co-author Dr. Beate Ritz emphasized that this research cannot conclusively prove a direct link between lithium exposure and autism diagnosis. Further investigation is required to determine whether any associations observed are causal or merely coincidental.
"Any drinking water contaminants that may affect the developing human brain deserve intense scrutiny," Dr. Ritz said in a statement.
The study's findings have sparked debate among experts, with some arguing that the association between high lithium levels and ASD diagnosis warrants further investigation. Others, however, point out that pharmacologic dosing of lithium in pregnant women with mental health disorders has not been linked to an increased risk of ASD.
"It's an interesting association, but causation is definitely not proven," said Dr. Max Wiznitzer, director of the Rainbow Autism Center at University Hospitals Rainbow Babies and Children's Hospital in Cleveland. "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."
The study's authors acknowledge that the exact cause of autism remains unknown, with genetics and environmental factors likely playing a role. However, they stress that any potential associations between drinking water contaminants and ASD diagnosis require careful consideration.
"We are bombarded with a variety of environmental stressors in our everyday lives," Dr. Wiznitzer said. "We have to figure out how to basically safely navigate them, and this is probably not one that's high on our list."
While the study highlights the need for further research into potential links between drinking water contaminants and ASD diagnosis, it also underscores the importance of continuing to monitor lithium levels in drinking water systems.
"As a society, we have a responsibility to ensure that our drinking water is safe for consumption," Dr. Ritz said. "This includes investigating any potential associations with health conditions like autism."

. I mean, if they're saying 24-26% higher risk is 'slight', what does that even mean? It's like they're trying to downplay the whole thing so we don't panic. And another expert said the association isn't proven which means... nothing's really being proven at all 
. Plus, everyone's just focusing on autism and not about how lithium levels can actually be good for people with mental health issues, you know? We should be talking about the benefits of lithium treatment instead of worrying about something that probably isn't even real 
my kid has ftd (fluoride teeth decay) and its affecting their smile 
do we need to switch to bottled water?? 
have been researching this stuff nonstop trying to stay safe
also, what's up with the lack of research on this topic previously? shouldn't we know more by now? 
We should be taking a closer look at our drinking water and making sure it's safe for everyone, especially pregnant women and their unborn babies.
. But Dr. Ritz is right, we need more info before we can say for sure what's going on here 
. Maybe this study will lead to more research and a better understanding of what's really going on with autism diagnoses 
. Anyway, I think it's time for our water utilities to get their act together and start monitoring those lithium levels ASAP 
!
? i mean, experts are saying it's too early to say for sure if one causes the other, but still... shouldn't we know what we're drinking? 
. Maybe this study will spark some important research and help us better understand what's going on with autism. Who knows? 
but honestly who knows what's going on here? 
and i'm just over here thinking "okay, let's get some more data before we start freaking out about it"
