amniocentesis, a prenatal diagnosis method in which a needle is inserted into the amniotic sac that surrounds the fetus. Amniocentesis is most often used to detect Down syndrome and other chromosomal abnormalities. This test is usually done in the second trimester, after 15 weeks of gestation.
What can cause autism during pregnancy?
The risk of autism is associated with several prenatal risk factors, including advanced age in either parent, diabetes, bleeding, and use of psychiatric drugs in the mother during pregnancy. Autism has been linked to birth defect agents acting during the first eight weeks from conception, though these cases are rare.
How can you prevent autism in babies?
