1) The common and scientific name of the disease.

The common name for this disease is Down's Syndrome but it is often referred to Trisomy 21 or Trisomy G. It is named after the famed British physician John Langdon Down who discovered this disease. There are three different types of Down's syndrome, Standard Trisomy 21, Translocation and Mosaicism. The most common form is Standard Trisomy 21.

2) What causes it?

There are many different causes for Down's syndrome as there are different types of it. Typically, we inherit 46 chromosomes from our parents, 23 from your mum and the other 23 from your dad. For people suffering with Down's syndrome they have an extra cell of chromosome 21, so instead they have 47 chromosomes instead of the usual 46 chromosomes. Therefore, this causes problems with their physical appearance. It is still unknown where Down's Syndrome originates from and there is still no way of stopping it from entering. However, scientist have discovered that women over the age of 35 have a higher chance of conceiving a child with Down's syndrome.

3) What are the symptoms? How long do they it last? Is it deadly?

There are many different symptoms that affect the physical and outer appearance. These symptoms can be treated but most of them are life long. Kids tend to have the same physical disabilities such as as a flat facial profile, an upward slant to the eyes, small ears, a protruding tongue and an very small chin. Hypotonia or a.k.a low muscle tone is a characteristic among children with Down's syndrome. This can be later improved as the child grows older but children suffering this often learn to sit up and walk much later than normal children. They are born the same size of most normal kids but their growing speed is slower and they tend to be smaller than most children. Young children sometimes have problems with their speech and they speak slower than others. Down's syndrome does not have a great affect on the brain. Only a small part of kids have medical problems such as lazy eye, hearing loss, near/far-sightedness and possibly cataracts. Unfortunately there isn't really a cure developed for curing these symptoms. However, there has been talk about using plastic surgery to help change their physical features though it has not been widely used.

4) Can it be cured? If so, how? If not, is there any way that we can at least treat it?

Unfortunately, there is no universal cure for each type of Down's syndrome. Treatment depends on what each person specific medical disabilities are. For example, a person with with congenital heart disease need to undergo major surgery quickly after birth. Others might have minor problems. Plastic surgery has been used on children to correct their facial features in hopes of a better life, though it is highly uncommon. It is also brings controversy as many people are against it. Tongue reduction has been used in order to improve a persons speech. However, researchers have found out that only 1 in 3 children have been successful in speaking. There are treatments for children who do have learning or development problems.
