Ultrasound scans, or sonography is an imaging technique based on sound waves that allows medical personnel to view a picture of the inside of the body to detect problems in the liver, heart, kidney, or abdomen, and to evaluate fetal development. Recent studies have found increased risk of autism and poorer nonverbal IQ in vulnerable fetuses when exposed to an ultrasound in the first trimester of pregnancy, detailing the mechanism to which toxic birth defects occur on the central nervous system of a developing fetus.
Severity of ASD symptoms and their correlation with the presence of copy number variations and exposure to first trimester ultrasound
“These data suggest that variation in ASD symptoms may result from exposure to diagnostic ultrasound during early prenatal development of children with specific genetic vulnerabilities. These results also add weight to on-going concerns expressed by the FDA about non-medical use of diagnostic ultrasound during pregnancy.”
“The rising rates of autism coincident with the increased use of ultrasound in obstetrics and its teratogenic/toxic effects on the CNS demand further research regarding a putative correlation.”
By the Children’s Health Defense Team Prenatal ultrasound is a taken-for-granted component of modern maternity care, to such an extent that most obstetrician-gynecologists find it impossible to practice their profession without it. American women now routinely undergo four to five ultrasounds per pregnancy. Despite the absence of demonstrated benefits, there is also a trend […]
