Generally, Down syndrome is a common chromosomal abnormality disorder. It is recommended to seek timely medical consultation, identify the cause, and then proceed with symptomatic treatment under a doctor's guidance. A detailed analysis is as follows:
Down syndrome primarily results from abnormalities in the 21st pair of chromosomes during cellular meiosis in the affected individual, such as trisomy or translocation, which lead to abnormal gene expression and subsequently cause a series of severe physical and mental developmental disorders. If one of the parents has Down syndrome, the likelihood of their child having Down syndrome increases. Exposure to radiation, viral infections, or chemical substances during pregnancy can also increase the risk of Down syndrome. Currently, there is no effective treatment for Down syndrome; comprehensive rehabilitation measures are mainly adopted to improve the quality of life for affected individuals.
