Can you tell if a baby has Down syndrome in an ultrasound?

An ultrasound can detect fluid at the back of a fetus’s neck, which sometimes indicates Down syndrome. The ultrasound test is called measurement of nuchal translucency. During the first trimester, this combined method results in more effective or comparable detection rates than methods used during the second trimester.

Can Down syndrome be cured during pregnancy?

The extra chromosome can’t be removed from cells, so there’s no cure for the condition. The chromosomes divide incorrectly by accident, not because of anything the parents have done.
