Although many children with Down syndrome have physical and mental limitations, they can live independent and productive lives well into adulthood. About one half of children with Down syndrome are born with heart problems, including atrial septal defect, ventricular septal defect, and endocardial cushion defects.
Each person with Down syndrome is an individual — intellectual and developmental problems may be mild, moderate or severe. Some people are healthy while others have significant health problems such as serious heart defects.
Personal experiences and some difficult issues
Some of the children with Mosaic Down syndrome that we know do not actually look as if they have Down syndrome - the usual physical features are not obvious.
Some people with Down syndrome marry. Most men with Down syndrome cannot father a child. In any pregnancy, a woman with Down syndrome has a 1 in 2 chance of conceiving a child with Down syndrome. Many of the pregnancies are miscarried.
Can a couple with Down syndrome have children? It is often difficult for a couple with Down syndrome to conceive a child due to low fertility in the male and lack of ovulation in the female and the likelihood of entering menopause early.
Most individuals with Down syndrome have mild (IQ: 50–69) or moderate (IQ: 35–50) intellectual disability with some cases having severe (IQ: 20–35) difficulties. Those with mosaic Down syndrome typically have IQ scores 10–30 points higher than that.
People with Down syndrome can expect to live to 60
In the 1940s, a child with Down syndrome had a life expectancy of 12 years. These days, their life expectancy is 60 years and a baby born with Down syndrome could live into their 80s — in line with the general population.
The average intelligence quotient (IQ) of children with DS is around 50, ranging between 30 and 70. Remarkably, a small number of patients have a profound degree of ID, whereas others have a mild degree despite the absence of any genetic, cultural or familial favoring or disfavoring causes.
Many pregnancies in women with Down syndrome produce children both with normal and with trisomy 21, whereas males are infertile. However, Down syndrome males are not always infertile and this is not global. Here we reported a 36-year-old man with proved nonmosaic trisomy 21 fathered two normal boys.
Mosaicism. Mosaicism (or mosaic Down syndrome) exists when there are a mixture of two types of cells, some containing the usual 46 chromosomes and some containing 47. Those cells with 47 chromosomes contain an extra chromosome 21. Mosaicism is the least common form of Down syndrome.
Down Syndrome rates increased over time among individuals who identify as Black, Hispanic, or AIAN, but not among white or Asian individuals. Whether accessing and navigating changes in Down syndrome testing is contributing to these disparities in outcomes needs further study.
Mosaicism, or mosaic Down syndrome, is diagnosed when there is a mixture of two types of cells. Some have the usual 46 chromosomes, and some have 47. Those cells with 47 chromosomes have an extra chromosome 21. Mosaicism is usually described as a percentage.
THE world's oldest Down's syndrome sufferer who was never expected to live beyond 12 has now celebrated his 77th birthday. Doctors suspected Kenny Cridge was stillborn when he arrived in 1939 with his twin sister Dorothy. Despite not being expected to make it into his teenage years, Kenny has defied the odds.
Trisomy ('three bodies') means the affected person has three copies of one of the chromosomes instead of two. This means they have 47 chromosomes instead of 46. Down syndrome, Edward syndrome and Patau syndrome are the most common forms of trisomy.
In a study of self-awareness among 77 children with DS using interviews, standardized tests, and photographs, over half were considered to have some level of self-awareness about their diagnosis but 13% refused to talk about their condition during their interviews [Cunningham and Glenn, 2004].
Many pregnancies in women with Down syndrome produce children both with normal and with trisomy 21, whereas males are infertile. However, Down syndrome males are not always infertile and this is not global. Here we reported a 36-year-old man with proved nonmosaic trisomy 21 fathered two normal boys.
Despite a wide range of individual differences, most children are late in saying their first words, their vocabulary grows more slowly than in ordinary children and although they use the same range of two- word phrases as all children, they have difficulty in mastering the many rules for talking in grammatically ...
Misconception: People who have Down syndrome don't feel pain. Reality: People with Down syndrome absolutely feel pain.
Currently, Ireland tops the countries with the highest rate of Down syndrome prevalence, as its incidence of the syndrome is reported to be 27.5 per 10,000 live births.
The largest number of deaths were observed during the first year of life. The survival fraction at 5 years of age was 0.697_+0.041. From ages 5 to 10, no death was observed. The most significant cause of death in children with Down's syndrome was cardio-respiratory diseases (80.5 per cent).
IQ test experts estimate his IQ was somewhere between 160 and 180, which is quite high. Some people estimate his IQ was just over 200, hovering around 205. However, 160-180 is the more commonly estimated range. Only one in over 11,000 people score a 160, and only one in every 3.5 million people score a 180.
For instance, among the 18 studies under scrutiny that did not explicitly state an IQ cut-off point the mean range of IQ among individuals with ADHD reported in the studies is from 102 to 110. Given that lower IQ is associated with ADHD this suggests that individuals with ADHD may be inaccurately represented.
The average dog's IQ is about 100. Based on the results done to test a dog's IQ, it turned out that dogs, even the average ones, have the IQ same as a 2-years old human.
