Is Down Syndrome a disability?
The extra chromosome affects the way the child’s brain and body develop, leading to developmental delays, intellectual disability and an increased risk for certain medical issues. Down syndrome is the most common genetic cause of intellectual disability, affecting approximately 1 in every 700 children.

Did Down syndrome exist in ancient times?
Ancient Bones Offer Clues To How Long Ago Humans Cared For The Vulnerable. At a site called Poulnabrone, on the west coast of Ireland, archaeologists found the skeleton of a baby with Down syndrome who died nearly 4,000 years ago — the oldest confirmed case of Down syndrome.
Does Down syndrome run in family?
Does Down Syndrome Run in Families? All 3 types of Down syndrome are genetic conditions (relating to the genes), but only 1% of all cases of Down syndrome have a hereditary component (passed from parent to child through the genes). Heredity is not a factor in trisomy 21 (nondisjunction) and mosaicism.
Does stress cause Down syndrome?
Down syndrome, which arises from a chromosome defect, is likely to have a direct link with the increase in stress levels seen in couples during the time of conception, say Surekha Ramachandran, founder of Down Syndrome Federation of India, who has been studying about the same ever since her daughter was diagnosed with …
How did Down syndrome get its name?
Down syndrome (DS), also known as trisomy 21, is caused by the presence of all or part of a third copy of chromosome 21 (Figure 1a, b). It is named after John Langdon Down, the British physician who described the syndrome for the first time in 1866.
Can Down syndrome be prevented?

Can trisomy 21 be prevented?
There is no cure for Down syndrome, but treatment is available to help your child. Your child may need physical, occupational, and speech therapy to help with their development.
What part of the body does it generally affect Down syndrome?
Down syndrome is a genetic disorder that can affect many different parts of the body. An extra part or whole Chromosome 21 is the cause of Down syndrome. It is the most common chromosomal abnormality. This syndrome can affect the heart, the brain, the hormone system and the skeleton.
Why is Down syndrome not curable?
Down syndrome is a random occurrence in nature. It has no cure or prevention measures. Down syndrome is not a disease, disorder, defect or medical condition and therefore does not require treatment, prevention or a cure.
What age does Down syndrome occur?
It is determined by many factors, but research suggests that there is a higher chance if the mother is older than 35 years of age. Before the age of 30, Down syndrome occurs in fewer than 1 in 1,000 pregnancies. After the age of 40, this figure rises to about 12 in 1,000.
At what age do Down syndrome babies talk?
Typically, these children have a much harder time learning to talk (expressive language) than with understanding what they hear (receptive language). On average, children with Down syndrome start using words around 16 months of age—about 6 months later than other children.
What was the first case of Down syndrome?
The oldest confirmed case of Down’s syndrome has been found: the skeleton of a child who died 1500 years ago in early medieval France. According to the archaeologists, the way the child was buried hints that Down’s syndrome was not necessarily stigmatised in the Middle Ages.
