Introduction
Under normal circumstances, Down syndrome is a common chromosomal abnormality disorder. For children already born with Down syndrome, rehabilitation training and special education should be started as early as possible to improve their self-care abilities and social adaptation skills. At the same time, parents should closely monitor the child's health status, conduct regular physical examinations, and promptly address any accompanying medical conditions.
Generally speaking, Down syndrome is a common chromosomal abnormality disorder. A detailed analysis is as follows:
Down syndrome is a congenital disorder caused by chromosomal abnormalities. Normal human cells have 23 pairs of chromosomes, but individuals with Down syndrome have an extra copy of chromosome 21, making it three copies instead of the usual two. This chromosomal abnormality leads to significant intellectual developmental delays, poor learning and self-care abilities, as well as distinctive facial features such as wide-set eyes, a flattened nasal bridge, small eye openings, and frequent protrusion of the tongue outside the mouth. Additionally, patients may have congenital heart defects, gastrointestinal malformations, weakened immune function, and other health problems. Currently, there is no effective cure, and the main approach is early intervention and rehabilitation training to improve the patient's quality of life.
For children already born with Down syndrome, rehabilitation training and special education should be started as early as possible to enhance their self-care abilities and social adaptation. Meanwhile, parents should closely monitor the child's health, schedule regular physical examinations, promptly address associated medical conditions, and provide good care and a supportive growing environment for the child.
