Question
A 6-month-old baby cannot lift its head, can roll over, and has normal appetite. There are no significant abnormalities, but the baby sometimes trembles. What should be done for a baby with chromosomal abnormalities?
Answer
Hello, detailed examinations of the fetus’s nuchal translucency can be done in the early pregnancy, and a fetal Down syndrome screening is performed between 16 to 18 weeks of gestation. The purpose is to exclude babies with fetal trisomy 21, trisomy 18 syndrome, fetal neural tube defects, and chromosomal karyotype abnormalities. These babies may develop mental retardation, deafness, and muteness after birth, so it is necessary to actively exclude fetal chromosomal karyotype abnormalities. If fetal neural tube defects are found, they should be addressed actively.
