Two recent studies concerning the prevalence of autism in the US have been getting a lot of attention, because they indicate that autism prevalence may be higher than previously estimated. This, of course, fuels the debate over whether or not there are environmental triggers of autism.
One study was conducted by the CDC but has yet to be published. The results were announced ahead of publication by the US Health and Human Services Secretary Kathleen Sebelius to the autism community. She reports that the new prevalence of autism spectrum disorder (ASD) is now estimated at 1% or 100 in 10,000 children. This is an increase over the last few years. In 2002 the prevalence was estimated to be 66 per 10,000.
The second study was published in the journal Pediatrics and is a phone survey of 78,037 parents. They asked if they had any children who had ever been diagnosed with an ASD. Here are the results: Read more »

Even though we intuitively think that a particular color looks the same to different people, researchers from The University of Chicago and Vanderbilt University have uncovered that the brain plays a critical role in color perception. The brain actually assigns colors to objects and with a bit of tinkering one can fool the brain to assign the wrong color to an object being viewed. Read more »

One of the major themes of the Science-Based Medicine blog has been to combat one flavor of anti-SBM movement that believes, despite all the evidence otherwise, that vaccines cause autism and that autism can be reversed with all sorts of “biomedical” quackery. Many (but by no means all) of these so-called “biomedical” treatments are based on the false view that vaccines somehow caused autism. I and my fellow SBM bloggers have expended huge quantities of verbiage refuting the pseudoscience, misinformation, and outright lies regularly spread by various anti-vaccine groups and two celebrities in particular, namely Jenny McCarthy and her boyfriend Jim Carrey. Most of the time, we discuss these issues in terms of the harm to public health that is done by falling vaccination rates due to the fear engendered by the message of the anti-vaccine movement and the threat of the return of vaccine-preventable diseases that once wreaked havoc among children.
There is another price, however. There is a price that is paid by autistic children themselves and their parents. It is a price paid in money and lost time. It is a price paid in being subjected to treatments that are highly implausible from a scientific standpoint and for which there is no good scientific evidence. It is a price that can result in bankruptcy, suffering, and, yes, even death. Read more »

When thinking of the health risks of smoking, almost everyone is aware that smoking causes lung cancer and respiratory diseases. The connection between inhaling smoke into the lungs and developing diseases of the lung is immediately plausible. But every year medical researchers discover more and more diseases that are worsened by smoking.
One example that recently caught my attention is multiple sclerosis (MS). MS is a very serious neurological condition caused partly by damage to the myelin sheath covering cells and their connections in the central nervous system. The precise neurological symptoms the person experiences depends largely on which part of their central nervous system is affected. Read more »

I think this is about the risk of seizures caused by video game flashing lights… But I’m not sure.
