Hello, Down syndrome, that is, 2 1- trisomy syndrome, also known as congenital stupidity or Down syndrome, is a disease caused by chromosome abnormality (an extra chromosome 2 1). 60% of the children miscarried early in the fetus, and the survivors had obvious mental retardation, special face, growth and development obstacles and multiple deformities.

Hello, there is no effective treatment at present. The best way is to terminate the pregnancy before the pregnant mother gives birth. You can also go to school to train mentally retarded children to master certain work skills. With patient education and training, under the supervision, people can take care of themselves, and even do simple social work and stand on their own feet. Parents and schools should help children overcome behavioral problems, and society should give moral support to parents of disabled children.
