Introduction Of Down Syndrome
Author : Chen Siong
Down syndrome is one of the common chromosomal abnormalities in the world. It is discovered by John Langdon Down in 1866 after observing the characteristics of some of the mental retardation children. There are many characteristics of this genetic disorder.
Basically, we can easily observe the Down syndrome child via their physical outlook. They almost look alike. This syndrome was described as “Mongoloids” before this. Yet, this is an insult to the Mongolians. Thus, the “Mongoloids” was forbid to be used in scientific field since 1960s.
One of the most common symptoms is the mental retardation. However, it depends to the level of severity of the symptom. Some of them cannot speak. It is not easy for them to learn. They need extra time to learn the things such as breast feed, walking, talking and dressing. There are some school that specifically designed for the Down syndrome child now. You can just join the group with some simple clicks online.
Another basic features is the poor development. The child cannot grow normally. We can easily recognize them with the small ears, head and eyes. Sometimes, we can see the upturned nose and flat face with them too. The malformations will cause some medical problems too. The medicine can help to reduce some of the symptoms effectively.
Besides, some of the Down syndrome has the symptom of hypogonadism. Usually, this only happen on the males. Thus, the males are usually infertile. Yet, the females’ menarche occurs at normal time. It is possible for them to pregnant.
Furthermore, there are many others medical problems that children with this birth defect may encounter. Usually, the Down syndrome babies are born with heart diseases. They are easy to get cancer than the normal children. Some of them are born with hearing impairment and poor vision too.
There are many hypotheses explaining the causes of Down syndrome. There is an extra chromosome 21 for the Down syndrome child. This is because of the non-disjunction occurred during the sperm or ovum development. Yet, it is related to the age of parents too. The increase of parental age will increase the risk of having a Down syndrome child. Many studies show that parents who are approaching 35 years old are in risk of having the child with this birth defect.
Lastly, raising a Down syndrome child is not easy. And I believe your love to the baby will overcome everything. Many parents of Down syndrome children would not wish to change a thing for bringing up their unique child even though they are given choice. For them, this is the great things to have such children.
