Almost one-half of babies with Down syndrome have congenital heart disease (CHD), the most common type of birth defect.
Potentially serious complications — The most serious complications of Down syndrome include heart defects, blood disorders that can include leukemia (cancer of the blood), and immune system problems. Heart defects — Approximately half of all babies with Down syndrome are born with (often repairable) heart defects.
Down syndrome occurs in people of all races and economic levels. The risk increases with the mother's age (1 in 1250 for a 25 year old mother to 1 in 1000 at age 31, 1 in 400 at age 35, and about 1 in 100 at age 40). However, 80% of babies with Down syndrome are born to women under age 35 years.
Children with Down syndrome have delays in speech and motor skills, and may need help with self-care, such as dressing and grooming. Medical problems associated with Down syndrome can vary widely from child to child. While some kids and teens need a lot of medical attention, others lead healthy lives.
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.
Those with Down syndrome nearly always have physical and intellectual disabilities. As adults, their mental abilities are typically similar to those of an 8- or 9-year-old. At the same time, their emotional and social awareness is very high.
In a sample of 75 children with trisomy for chromosome 21, or Down syndrome, there were 42 males and 33 females. The sex ratio was 1.30 which is statistically not significant (p greater than 0.05).
Toddlers and older kids may have delays in speech and self-care skills like feeding, dressing, and using the toilet. Down syndrome affects kids' ability to learn in different ways, and most have mild to moderate intellectual disability. Kids can and do learn, and they can develop skills throughout their lives.
Pulmonary infectious disease is the leading cause of mortality in Down syndrome, caused by both intrinsic (morphological factors) and extrinsic (immune dysfunction) factors. Listed in each organ cartoon are genes implicated in disturbed heart, lung and immune function.
Down syndrome varies in severity among individuals, causing lifelong intellectual disability and developmental delays. It's the most common genetic chromosomal disorder and cause of learning disabilities in children. It also commonly causes other medical abnormalities, including heart and gastrointestinal disorders.
Trisomy 21 (Nondisjunction)
Down syndrome is usually caused by an error in cell division called “nondisjunction.” Nondisjunction results in an embryo with three copies of chromosome 21 instead of the usual two. Prior to or at conception, a pair of 21st chromosomes in either the sperm or the egg fails to separate.
It occurs because either the egg or the sperm involved in the formation of the embryo carried an extra copy of Chromosome 21. The vast majority of cases (about 90%) of Down syndrome are due to a problem with the egg. A small percentage of all eggs (and sperm) have abnormal chromosome arrangements.
Trying to make them feel better with words like these might be appreciated by some parents and not by others. It is best to avoid this. “They're such loving children.” This is a stereotype of people with Down syndrome and a statement like this demonstrates that you really don't know much about Down syndrome.
Most of the time, it's at a moderate level. If you have a baby with Down syndrome, you'll need to care for, talk to, play with, and love them like any other infant. It's important to have high expectations for your baby with Down syndrome.
Children and adults with Down syndrome experience all the same emotions everyone experiences, both good and bad. They also experience mental health disorders including depression, anxiety, obsessive-compulsive disorder, and others.
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.
Yes. A woman with Down's syndrome can have children. If her partner does not have Down's syndrome, the theoretical chance of the child having Down's syndrome is 50%. There have been only a few reports of men with Down's syndrome fathering children.
Their personality characteristics vary, as well. Think of the different personality traits that typical people have and you have just as many traits that can occur in people with Down syndrome – they can be funny, sarcastic, indifferent, ambitious, laid back, high strung, loving… the list could go on forever.
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.
Behavior changes in adults with Down syndrome have many potential causes. Some individuals have difficulty with the transition into adulthood as they face the loss of social networks, departure of older siblings, death of loved ones, changes in housing, and the challenge of obtaining meaningful work.
The rate of Down syndrome for both maternal and paternal age greater than 40 years is approximately 60 per 10,000 births, which is a six-fold increase compared with maternal and paternal ages less than 35 years of age. In this age group, the paternal contribution to Down syndrome was 50 percent.
They have similar features due to extra genetic material that affects growth of the maxilla (part of the skull) and the bone, cartilage, and connective tissue in the head, known as the cranial neural crest. 15 It creates common Down syndrome features such as upturned, almond-shaped eyes and a smaller head.
I.Q. scores for people with Down syndrome vary, with the average cognitive delays being mild to moderate, not severe. In fact, normal intelligence is possible. If a person with Down syndrome has difficulty with hearing, it can be misinterpreted as a problem with understanding.
