Down syndrome is named after the English doctor, John Langdon Down, who was the first to categorize the common features of people with the condition.
Dr. Jerome Lejeune discovered Down syndrome is a genetic disorder whereby a person has three copies of chromosome 21 instead of two.
There are also very rare forms of Down syndrome (less than 6%) called Translocation Down Syndrome or Mosaic Down Syndrome in which not all of the chromosome is triplicated or not all cells of the body carry the extra chromosome.
Down syndrome is the most frequently occurring chromosomal disorder and the leading cause of intellectual and developmental delay in the U.S. and in the world.
What is the cause of Down syndrome?
The cause of Down syndrome is unknown.
In a process called non-disjunction, the two copies of chromosome 21 fail to separate during formation of the egg, resulting in an egg with two copies of the chromosome. When this egg is fertilized, the resulting baby ends up with three copies of chromosome 21 in each of its cells. The cause of this non-disjunction remains unknown.
The chance of having a baby with Down syndrome increases with the mother’s age; however, about half of babies born with Down syndrome are born to mothers under 35 years old simply because more young women are having babies.
Down syndrome has nothing to do with race, nationality, socioeconomic status, religion, or anything the mother or father did during pregnancy.
There is NO correlation between incest and Down syndrome.
Between two and four percent of the time, a person is born with Mosaic translocation Down syndrome (mDs) whereby some but not all of the cells have an extra copy of the 21st chromosome and the other cells are not affected. Translocation happens when a piece of chromosome 21 becomes attached to another chromosome during cell division.
In the case of hereditary Translocation Down syndrome (a rare one to two percent of all people with Down syndrome), an extra chromosome 21 is inherited from one of the parents. care for people with down's syndrome
Infants with Down Syndrome on the whole have terrible muscle tone . As a result, feeding babies with Down Syndrome by and large takes longer. Mothers breast-feeding babies with Down Syndrome should search advice from an trained on breast feeding to make certain the little one is getting sufficient diet.
Bad muscle tone can purpose constipation in toddlers. Additionally, a malformation of the higher a part of the backbone placed beneath the base of the skull, which is reward in some contributors with Down Syndrome, can motive compression of the spinal twine if it isn't handled safely.
Scientist maintain toddlers with Down Syndrome will have to incorporate the same good-baby care that different infants receive. Additionally, particular concentration will have to be paid to problems that are extra normal in kids with Down Syndrome.
Young adults and younger Adults
temper swings, pushing boundaries, tiredness, feeling pressured, crushes, first loves and spending ages within the lavatory whilst these changes may just occur a little bit later than in folks with out Downs syndrome, young people with Downs syndrome will practically be just like any other teen. Sex and relationships, trying independence, just right individual hygiene, desiring private space building good self-esteem are all issues that you will need to think about as your son or daughter grows up.
