Question
What are the dangers of Down syndrome?
Answer
Down syndrome, also known as trisomy 21, is characterized by intellectual disability, a distinctive facial appearance, and may be accompanied by digestive tract abnormalities or congenital heart disease. The impact on intelligence is the most significant and severe. If a fetus is diagnosed with Down syndrome, it is usually recommended to terminate the pregnancy, as this condition not only brings pressure to the family but also imposes a burden on society. Severe cases may also lead to cerebral palsy and intellectual disabilities, and most patients lack fertility.
