fluoride lowers iq

Fluoride lowers IQ – hey vaccine deniers, this study is almost useless

Recently, I wrote an article about the published study that seemed to show that fluoride lowers IQ in children. I predicted that the anti-vaccine religion would jump all over it as an indication that public health authorities are useless – it took like an hour before the anti-vaxxers employed all of their useless pseudoscience and conspiracy theories to jump all over that. 

I was somewhat ambivalent about the research, but I thought it might be an indicator that there could be an issue with water fluoridation. However, upon further review, I’ve come to the realization that this was pretty much worthless.

So do we know if fluoride lowers IQ? Based on research published in JAMA Pediatrics, no we don’t. In fact, I’m willing to state that we should be confident that fluoridated water is still safe while preventing cavities.

Let’s take a look at what I’ve noticed.Read More »Fluoride lowers IQ – hey vaccine deniers, this study is almost useless

pesticides cause autism

Pesticides cause autism – the scientific evidence is quite weak

Along with the thoroughly debunked “vaccines cause autism,” a related trope is pesticides cause autism spectrum disorder (ASD). The evidence that supports that claim is fairly weak, possibly nonexistent, but that’s what we do here – examine the evidence.

For reasons beyond the scope of this blog and my interests, parents need to find blame for why their children may have been diagnosed with an autism spectrum disorder.  A few years ago, Emily Willingham, Ph.D., whom I consider to be one of the leading ASD scientific experts on this planet, wrote a hysterical and scientifically skeptical article about all of the popular causes of ASD. Older mothers. Older fathers. Depressed mothers. Fingers. Facial features. Facial features?

Today, I keep seeing the new claim that pesticides cause autism. Time to see what kind of science supports this claim.Read More »Pesticides cause autism – the scientific evidence is quite weak

Flu vaccinations for children with neurological disorders

Flu virus.

The Centers for Disease Control and Prevention (CDC) has just published a study in Pediatrics on the effects of influenza in children with neurologic disorders. It compared the outcomes, during and after the flu ,between kids with or without neurological disorders. The outcomes studied were deaths and hospitalizations during the H1N1 influenza pandemic, between April 15 and September 30, 2009, by looking at medical records of reported pediatric deaths.Read More »Flu vaccinations for children with neurological disorders
