Question
The family suspects their child has Down syndrome. What are the symptoms?
Answer
Down syndrome, also known as trisomy 21, is a congenital defect disease caused by genetic factors. Although there is no effective treatment for this condition at present, measures such as reasonable genetic counseling, enhanced maternal health care, and reducing the pregnancy rate of elderly women can help lower the incidence rate. Additionally, preventing infectious diseases, early supplementation with vitamin B6, r-tyrosine, folic acid, and other nutrients may aid in symptom improvement. At the same time, consideration can be given to surgical correction for related malformations.
