Prenatal exposure to ultrasound waves impacts neuronal migration in mice
This is another one of “those” topics that you just can’t discuss with a pregnant woman. The fact is, there has NEVER, EVER been any safety studies on long term effects of ultrasounds during pregnancy. Before anyone jumps on me for this statement, consider these few items.
A study a few yrs back found that ultrasound during pregnancy increased the likelihood that the infant will be left handed. Not much, but it does suggest that US affects something deep in our programming.
Now we have this study, that finds that US during pregnancy in mice affect the way the neurons moved around during development and even stopped some of them from making it to the areas of the brain they were destined for. Lastly, we have several organizations coming out against the use of 3-D US in retail centers because they say the safety of these types of tests are not established. So, other than exposure at one time (typical OB office will US often enough to make up that difference), how is the 3-D different enough from normal US to be a concern? Throw on top of this that US rarely lead to a change in the outcome of a pregnancy, and you have to ask yourself–why so many US for our pregnant women and how is this affecting their unborn child?
