Introduction
After birth, children with Down syndrome exhibit distinct facial features, such as widely spaced eyes, a flattened nasal bridge, and small mouth, teeth, and ears. Their head circumference may be smaller than that of typical children, although it can also fall within the normal range. As they grow older, these children may experience intellectual disability, delayed growth and development, and speech impairments. They may also have associated conditions such as congenital heart defects and cleft lip.
The head circumference of a child with Down syndrome may be slightly smaller compared to that of a normal child, although in many cases there is not a significant difference.
In clinical practice, Down syndrome is a human chromosomal disorder and one of the most common causes of intellectual disability. At birth, children with Down syndrome typically exhibit distinct facial features, such as widely spaced eyes, upward-slanting eye fissures, a flattened nasal bridge, small mouth and teeth, abnormally shaped ears, and hands with a characteristic single palmar crease (simian crease), among other traits. Their head circumference may be slightly smaller than average or fall within the normal range. As children with Down syndrome grow older, they often display intellectual delays, delayed growth and development, and speech impairments. They may also have associated congenital conditions such as congenital heart defects, cleft lip, or congenital esophageal abnormalities, all of which can significantly impact their quality of life.
There is currently no effective cure for Down syndrome. Prevention primarily involves prenatal screening during pregnancy, which may lead to termination of affected pregnancies. Additionally, appropriate rehabilitation training can help individuals with Down syndrome achieve varying degrees of independence in daily living.
