Some cases of Down syndrome can be prevented by being aware of the disease risk factors and also utilizing available screening tests:
- Mainly, the older the mother (more than 30 years old), the higher the chance of chromosomal errors and Down syndrome.
- Also, if there is a history of previous children with Down, then there is a much greater chance of having another affected child.
- Screening tests are now standard in most prenatal care and can give parents an idea of the likelihood of chromosomal abnormalities.
There are exceptions to all the above, and so not all cases can be prevented. For more info you can go to a specialist.
