Yes, people with Down syndrome have mental capacity, but it typically involves some degree of intellectual disability (usually mild to moderate) and developmental delays, affecting thinking, learning, and processing information, though abilities vary widely, and with support, they can learn, work, and lead fulfilling lives, making decisions and achieving much more than often assumed.
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.
Today the average lifespan of a person with Down syndrome is approximately 60 years. As recently as 1983, the average lifespan of a person with Down syndrome was 25 years.
Most children with Down syndrome meet developmental milestones later than other children, including the ability to walk and talk. They often have mild to moderate intellectual disability and may have specific challenges with attention span, verbal memory, and expressive communication.
Independent Living
People with Down syndrome may be capable of living independently. It is completely up to the individual and their needs if they wish to do so.
The answer is a resounding yes. People with Down syndrome can and do date, fall in love, and get married. Just like anyone else, they experience attraction, build meaningful relationships, and dream of sharing their lives with someone special.
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.
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.
“We certainly see some kids who are less affected than others, but we shy away from terms like 'low-functioning' and 'high-functioning,'” Pipan explains. Some children with Down syndrome have a hard time learning to walk, and others have no problem running and jumping and riding a bike.
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.
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.
Postmortem studies in adults with DS have found several brain abnormalities, including reduced gross brain weight, a lower number and depth of cerebral sulci, enlarged ventricles and hypoplasia of several brain structures such as the brainstem, cerebellum, frontal and temporal lobes.
Don't speak in clichés.
When you're a parent of a new baby with Down syndrome, “special” sounds a little like a euphemism for “weird and different” and I'm pretty sure the last thing you want to be telling the parents is that they or their newborn is weird.

Borderline personality disorder usually begins by early adulthood. The condition is most serious in young adulthood. Mood swings, anger and impulsiveness often get better with age. But the main issues of self-image and fear of being abandoned, as well as relationship issues, go on.
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.

On average, children with Down syndrome start using words around 16 months of age—about 6 months later than other children. Children with Down syndrome are often taught sign language to enhance communication and bridge the gap between expressive language and receptive language.

Down syndrome is not new — in fact, the first evidence of its existence dates back 2,500 years. The facial features of DS are found in some ancient pottery and paintings. The syndrome is named after John Langdon Down, an English doctor who published a clinical description in 1866.
