Question
My nephew has never learned to walk and it feels very strange. He was later diagnosed with Down syndrome. I want to know how to prevent Down syndrome in daily life.
Answer
According to the information provided, Down syndrome is a congenital disease. To prevent this condition, it is necessary to undergo appropriate checks during pregnancy. Typically, Down syndrome screening can be conducted between 16 and 20 weeks of pregnancy. If the results are abnormal, further chromosome testing is required for a definitive diagnosis. If an infant is diagnosed with Down syndrome due to a genetic abnormality, abortion may be necessary.
