Question

A 6-month-old baby cannot lift her head but can roll over, has normal appetite, and shows no other obvious symptoms. However, she occasionally trembles. What are the possible causes of chromosomal abnormalities in babies?

Answer

The causes of chromosomal abnormalities are complex, potentially involving congenital factors or environmental influences, and it is currently difficult to determine the specific cause. If the baby is diagnosed with a chromosomal abnormality, such as Trisomy 21, treatment options are limited.
