Yes, people with Down syndrome are smart and capable, but typically experience mild to moderate intellectual disabilities, meaning they may learn more slowly or differently, with strengths in areas like social skills, memory, or visual learning, while facing challenges with language or abstract concepts. Like anyone, they have unique talents and potential, with some attending college, living independently, and contributing to their communities.
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.
Mosby's Medical, Nursing and Allied Health Dictionary gives an average IQ of between 50 and 60 for Down's syndrome individuals although IQ scores of 120 have been found in some individuals with the syndrome.
The life expectancy for people with Down syndrome has dramatically increased, now averaging around 60 years, a significant rise from just 25 years in the 1980s, thanks to improved medical care, early interventions, and better support systems, allowing many to live healthy, active lives into their 60s, 70s, and beyond. However, this can vary, with some research highlighting disparities in life expectancy, especially across different racial groups, and noting increased risks for certain age-related health issues.
The prevalence rate of Down syndrome is slightly higher among males than females. This statistic shows the age-standardized prevalence rate of Down syndrome worldwide in 1990 and 2019, by gender.
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.
The mental age is rarely over 8 years old, although a few cases of normal Intelligence Quotient (IQ) in children with DS have Page 2 Cognitive development and adaptive functions in children with Down syndrome at different developmental stages 85 been reported 4.
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.
Alzheimer's disease associated with Down syndrome: a genetic form of dementia. Adults with Down syndrome develop the neuropathological hallmarks of Alzheimer's disease and are at very high risk of developing early-onset dementia, which is now the leading cause of death in this population.

It is important to acknowledge that there are also children and teenagers with Down syndrome who struggle with social skills to some degree. Shyness, group avoidance, solitary preferences, lacking eye contact, lack of responses can lead to challenges both in school and home settings.

Pablo Pineda

Most of the time, Down syndrome is not passed down in families. The condition is caused by a random unusual cell division. This can happen during the development of the sperm cell or the egg cell or during early development of the baby in the womb. Translocation Down syndrome can be passed from parent to child.
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.

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 ...
The number of people is probably between 13,000 and 15,000. This means that in a group of 10,000 people in Australia, there are just over 5 people with Down syndrome. This is about the same as in other countries such as the UK. For every 1100 babies born in Australia, 1 will have Down syndrome.
