What is Down syndrome and who does it affect?

Down syndrome is a genetic condition affecting development. An estimated 4–5 million people worldwide live with Down syndrome, which influences cognition and health across the lifespan.

How is Down syndrome detected during the prenatal stage?

During pregnancy, certain tests may indicate Down syndrome. Screening results should be reviewed with healthcare professionals, who can guide next steps and discuss options appropriate to each family.

What cognitive changes occur in Down syndrome development?

Cognitive differences commonly involve language and communication, comprehension, and memory. These domains may require tailored support across childhood and beyond.

What physical health issues accompany Down syndrome across life?

Physical involvement can include more noticeable hypertonia and increased gastrointestinal and cardiac problems. Ongoing specialized medical monitoring helps identify and manage complications throughout life.

Which treatments and therapies support people with Down syndrome?

Care typically combines therapies, medication, and other supports: physical therapy, occupational therapy, speech therapy, psychological therapy to improve cognitive functioning, and specialized medical monitoring to prevent health complications.

Does early intervention improve outcomes in Down syndrome?

There is currently no cure for Down syndrome. Early, appropriate intervention tailored to each child's needs, plus family and school support, can help individuals reach their highest level of functioning.

The cognitive changes of this syndrome affect developmental areas such as language and communication, comprehension, and memory.

There is also physical involvement in terms of health, such as more noticeable hypertonia, and gastrointestinal and cardiac problems throughout life.

Treatment for people with Down syndrome is a combination of therapies, medication, and other care. This includes:

physical therapy,
occupational therapy,
speech therapy,
psychological therapy to improve cognitive functioning,
specialized medical monitoring to prevent health complications.

Currently, there is no cure for Down syndrome, but an early, appropriate intervention tailored to each child’s needs can help them reach their highest level of functioning. Family and school support are also essential to achieve the best possible quality of life and good development for people with Down syndrome.
