How are birth defects detected?
Some birth defects can be diagnosed before birth through ultrasound, amniocentesis or chronic villus sampling (CVS). Most women have blood tests to screen for their risk of having a baby with a specific birth defect, such as Down syndrome and spina bifida.
How can defects be detected early?
First trimester screening is a combination of tests completed between weeks 11 and 13 of pregnancy. It is used to look for certain birth defects related to the baby’s heart or chromosomal disorders, such as Down syndrome. This screen includes a maternal blood test and an ultrasound.
When do you know if your baby has birth defects?
Tests used to diagnose birth defects may include amniocentesis (also called amnio). This test takes some amniotic fluid from around your baby in the uterus (womb) to check for birth defects and genetic conditions in your baby. You can get this test at 15 to 20 weeks of pregnancy.
What birth defects are most common?
If a baby is born with a part of the body that is missing or malformed, it is called a structural birth defect. Heart defects are the most common type of structural defect. Others include spina bifida, cleft palate, clubfoot, and congenital dislocated hip.
What is the most popular birth month?

August is the overall most popular month for birthdays, which makes sense, considering a late August birthday means December conception.

What ethnic group has the highest rate of birth defects?
American Indians had the highest rates of lethal birth defects, followed by Asians, Hispanics, and blacks. The variation in rate of lethal birth defects among racial/ethnic groups may have been related to both incidence and survival.
What ethnic group has the lowest rate of birth defects?
Cubans and Asians, especially Chinese and Asian Indians, had significantly lower occurrence of many of the studied birth defects, compared to non-Hispanic whites.
Is autism a birth defect?
The causes of autism spectrum disorders (ASDs) are unknown, although genetic and environmental influences have been implicated. Previous studies have suggested an association with birth defects, but most investigators have not addressed associations with specific diagnostic categories of ASD.
Which parent is responsible for autism?
Autistic children may inherit DNA mutations from their fathers. There is no one gene that, when mutated, causes autism. But over the past decade, researchers have identified hundreds of gene variations that seem to affect brain development in ways that increase the risk of autism.
Can autistic child become normal?
In severe cases, an autistic child may never learn to speak or make eye contact. But many children with autism and other autism spectrum disorders are able to live relatively normal lives.
