Congenital Down syndrome, also known as Down syndrome or Trisomy 21 syndrome, is a chromosomal disorder characterized by abnormalities in chromosome 21. Babies with Down syndrome can be referred to as Down syndrome infants. The birth of Down syndrome infants can bring significant psychological and economic burdens to families. So, what are the symptoms of congenital Down syndrome in babies?
Babies with congenital idiocy may exhibit distinct facial features, such as short head shape, round and flat face, low ear position, small ears, wide distance between eyes, small eye slits, nystagmus, low and flat nasal roots, upturned nostrils, small mouth, half open mouth, high palate arch, thick lips, thick tongue often protruding out of the mouth, frequent silly laughter, and a dull appearance.
The baby's neck and back are short and wide, with bulging abdomen accompanied by rectus abdominis separation and umbilical hernia, which may be accompanied by digestive tract deformities. The baby's limb muscle tension is low, the limb joints are soft, and there are obvious skeletal abnormalities. The hands are not only wide and thick, but also the fingers are short and short. The middle and distal phalanges of the little finger are poorly developed, and the end is bent inward. The thumb of the foot is far away from the other four fingers.
Infants with congenital idiocy also have intellectual disabilities, with a wide range of intellectual deficiencies. At the age of 5, their IQ is around 50, and as they age, their intelligence continues to decline. By the age of 15, their intelligence is only around 38, lacking abstract thinking ability. Their weight is lower than normal, making them highly susceptible to respiratory infections, digestive disorders, and leukemia.
