Life expectancy for people with Down syndrome is lower primarily due to associated health issues like congenital heart defects, increased risk of infections, respiratory problems (sleep apnea), gastrointestinal issues, and earlier onset of conditions like Alzheimer's disease, though advancements in medical care are significantly improving longevity, with average life expectancy now around 60 years.
The life expectancy of people with Down syndrome increased dramatically during the 20th century but appears to be leveling off. Alzheimer's disease, which occurs at a higher rate and at a younger age in people with Down syndrome, seems to be the main cause.
The two most common causes of death are respiratory and cardiac diseases (Ibster et al., 1975). According to Hurst and Logue (1970), 50 per cent of patients with Down's syndrome had congenital heart disease, a combination of cardiac congestion and pneumonia being the most common cause of death among them.
Key points. Down syndrome is the most common genetic cause of intellectual disability and appears to be characterized by an accelerated aging, affecting in particular the central nervous system, with a number of features that overlap with Alzheimer's disease.
The intelligence quotient (IQ) among children with Down syndrome varies but averages about 50, compared with children in the general population, whose average IQ is 100. Children with Down syndrome often have delays in developing motor and language skills, but this is variable.
Despite the presence of these brain changes, not everyone with Down syndrome develops Alzheimer's symptoms.
Because many people with Down syndrome get around easily, those individuals may be able to live on their own. They may be completely independent and live by themselves, or they may live in a group setting with friends or family, says Dr. Vellody.
The average IQ of a young adult with Down syndrome is 50, equivalent to the mental age of an 8- or 9-year-old child, but this number varies widely. At the same time, they enjoy a rich social and emotional awareness.
According to the World Health Organization, the highest prevalence of Down syndrome is reported in countries such as Ireland, Israel, and Turkey. In contrast, countries like Japan and South Africa report a lower incidence of Down syndrome.
Can adults with Down's syndrome have children; and if so, what is the chance of their children having the condition? 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%.
Of the people with Down syndrome in the United States: 67% are non-Hispanic and White, 13% non-Hispanic and Black, 16% Hispanic, 3% Asian or Pacific Islander, and 1% American Indian or American Native.
Visual acuity (clearness of vision) is poorer in all people who have Down's syndrome. Over half of people who have Down's syndrome need to wear glasses but EVERYONE who has Down's syndrome has poor visual acuity.
ALSO, YES. Provided they're of legal age, there's no inherent reason an individual with Down syndrome can't consume alcohol. If people with Down syndrome don't drink alcohol, it's likely due to other factors rather than the condition itself. Yet, the myth persists.
There's no way to prevent Down syndrome. If you're at higher risk of having a child with Down syndrome or you already have one child with Down syndrome, you may want to talk with a genetic counselor before becoming pregnant.
The cause of roughly 70% of all dementia cases is Alzheimer's disease, a progressive brain disorder characterized by the buildup of amyloid plaques and tau tangles, leading to memory loss and impaired thinking that interferes with daily life, making it the most common form of dementia.
The term "sundowning" refers to a state of confusion that occurs in the late afternoon and lasts into the night. Sundowning can cause various behaviors, such as confusion, anxiety, aggression or ignoring directions. Sundowning also can lead to pacing or wandering.
Individuals with Down syndrome are at a higher risk of being overweight or obese compared to those without Down syndrome. Several factors may contribute to this increased risk including hormonal imbalances, sleep patterns, physical activity levels, hypothyroidism, mental health conditions, and medications.
Refractive errors (need for glasses) – Children with Down syndrome are more likely to need glasses than other children. This may be due to myopia (nearsightedness), hyperopia (farsightedness), and/or astigmatism. Refractive error may develop early in life or later on.
People with Down syndrome will typically have some level of learning disability and characteristic physical features. There are some health problems associated with Down syndrome, such as heart problems and difficulties with sight and hearing, but these will not affect everyone with the condition.
The latest research highlights that these countries suffer the most from Down Syndrome.
Furthermore, though there are some indications in the Census data that incidence at birth may be falling, it is likely to remain comparatively higher than elsewhere because of a relatively large family size and high fertility rates in the 35 years and over age-groups and also because amniocentesis and abortion are not ...
Those with Down syndrome nearly always have physical and intellectual disabilities. As adults, their mental abilities are typically similar to those of an eight- or nine-year-old. At the same time, their emotional and social awareness is very high.
By now, it's clear: Yes, people with Down syndrome can get married, and many already have. We've seen what dating, love, and commitment can look like when individuals are supported with respect, education, and high expectations. Love is not limited by diagnosis.
After much research on these cell division errors, researchers know that2: In the majority of cases, the extra copy of chromosome 21 comes from the mother through the egg. In a small percentage (less than 5%) of cases, the extra copy of chromosome 21 comes from the father through the sperm.
