Down Syndrome: Symptoms, Types & Treatment

What Is Down Syndrome

Down syndrome is also known as DS or DNS. This is a genetic disorder. Our human body is made of millions of cells. Cells contain a nucleus which is the control center of the cell. Chromosomes are present inside the nucleus. Chromosomes play a vital role in cell division and genes transfers. Our inherited qualities are transfer to us through these chromosomes. So a normal person has 46  chromosomes in each cell. On the other hand, sometimes a person has an extra chromosome, that extra one causes down syndrome. It was first discovered in the late nineties.

This extra chromosome makes the development process in slow. Down syndrome is visible since birth. The babies with this disease usually have flat features with small eyes and weak muscles. Babies with down syndrome are born like a normal child with normal weight. However, their development is slower.

Moreover, they have digestive issues. Though down syndrome is not completely recoverable, but situations can improve. With hard work, these babies can become an active participant in society.

This syndrome is common in America. About one in every 700 children has this syndrome — moreover, 6000 babies born with down syndrome in America every year.


Types Of Down Syndrome

There are three types of Down Syndrome.

  • Trisomy21: This is the common most down syndrome. In this, each cell has one extra copy of chromosomes. Like instead of 46, a cell has 47 chromosomes. This extra makes the development process slow. The extra one is either in a sperm or an egg and is not separated. About 95% of the down syndromes are trisomy21.
  • Translocation: In translocation, chromosome breaks, and this broken one is attached to another chromosome. This presence causes characteristics of down syndrome. About 5% percent of the down syndrome is translocation.
  • Mosaicism: This is the least common type of chromosomes. In this, the extra chromosome is present in some of the cell preferably all. As some of the cells contain 46 and others contain 47 chromosomes.

Most of the obstetricians and gynecologists in America recommends down syndrome test during pregnancy regardless of age. Usually, it is done when there is a history of DS in the family, especially at the male side. Moreover, blood tests are done for down syndrome. In the case of some positive results, more tests are done.

Cvs the other way to diagnose. In CVS, cells are taken from the placenta to check the extra copy of fetal chromosomes. Ds tests can be after birth.

Sometimes babies are born with DS physical features, but in reality, they don`t have down syndrome. So chromosomal karyotype is done to make sure about DS. Fish is another type of test which diagnoses DNS after birth.


Down Syndrome Treatment

Treatment of DNS is different for everyone. However, this treatment should start at an early age. There is no proper treatment for this disease. However, we can reduce the effects and make them some responsible citizens through these actions:

  • Speech therapy and physical therapy should start at an early age.

  • Occupational therapy is best to make them positive participant of the society. This therapy helps in refining motor skills to make daily tasks easy.

Moreover, there are special schools for children facing DNS. They are equipped to handle the needs of such a student. There is a first reading and speech therapist. Getting help from them will raise the child in a better way.


Down Syndrome Facts

There are some research findings regarding down syndromes which are universally accepted.

  • DS is a condition rather a disease.
  • More than 400000 people are living with DS alone in America.
  • The average life expectancy of such a person is 60 years now; however, until 1983, it was 25 years.
  • It is not due to environmental factors. Maternal age is the only known factors.
  • This ailment cannot be prevented. However, its risk is controllable to an extent. Mothers can get folic acid during pregnancy.


Down Syndrome Pregnancy Test

There are two types of tests to test the DS during pregnancy.

  • Screening test tells chances of DNS. However, it is not confirmed yet. This just shows chances of the disease.
  • Diagnostic test: this test makes sure of DS. Cvs is the test which takes a sample of the cell a then confirms results of screening tests. We can consider its result authentic.
