Down syndrome

***Down syndrome*** (or ***trisomy 21***) is a genetic disorder. Most people with Down Syndrome have an extra copy of chromosome 21, or part of it.

Down syndrome causes a mental handicap. It may be mild or severe. The average IQ of a young adult with Down syndrome is 50, equivalent to the mental age of an 8- or 9-year-old child, but it truly depends on the person. This can vary widely, but most individuals need supervision if they are to live their lives in a satisfactory way. Children who have this condition take more time to learn new things.

The condition is named after John Langdon Down, the British doctor who first described it in 1866. Historically (in the past) it was called mongolism. Today the historical name is not used, likely because it is offensive to people with Down syndrome. During that time, a person also with the condition was  as a mongolian idiot, while today, a person also with Down syndrome would be referred to as that.

There is discrimination against people with Down syndrome, both in the education system and in society in general. Some people with the condition may have average intelligence but may also have other noticeable features of the disability. For example, people with Down syndrome often have a different shape of eyes than those without the syndrome. Some people with the condition have severe learning difficulties.

Of every 800 to 1000 babies that are born, one is diagnosed with Down syndrome. Older women have a higher chance of having a baby with Down syndrome. If they have a procedure known as amniocentesis, pregnant mothers can be told whether their fetus has Down syndrome. Ultrasound scans may also diagnose the presence of Down Syndrome. Mothers whose fetus is diagnosed as having Downs syndrome may choose to have an abortion. In the United Kingdom and Europe 92% of such cases are aborted.

There are several options for care of individuals with Down syndrome as they grow older; many individuals are able to live independently or with the support of a PCA.

## Features 
They also grow differently from other children. Babies with down syndrome can be identified at birth because they may have a specific set of physical features. These features include narrow eyes, a flat nose-bridge, smaller mouths and shorter fingers. Smaller mouths can result in tongue protrusion or what looks like a large tongue. Sometimes the little fingers curve inwards as well, and there is also often a space between the big toe and the others. People with Down syndrome often have heart defects or Alzheimer's disease when they are older. About 90% of people with Down syndrome live through their teens. The lifespan of a person with Down syndrome averages between 50 and 55 years old.

So far there have been no treatments for Down syndrome.
