What it is
Down's syndrome is a genetic condition caused by having an extra copy of chromosome 21. It is usually present from conception and is not caused by anything parents did. It leads to some degree of learning disability (which varies widely) and characteristic physical features, and is associated with a higher chance of certain health conditions — such as heart differences (often present at birth), hearing and vision problems, thyroid conditions, and others — which are monitored for and treated. Every person with Down's syndrome is an individual with their own personality, abilities and needs. With good healthcare, early support and inclusion, people with Down's syndrome lead full, meaningful lives, and life expectancy has improved greatly.
How it is treated
There is no treatment for the underlying genetic condition, and care focuses on supporting development, health and wellbeing across life. This includes early intervention and therapies (such as speech and language and physiotherapy), inclusive education tailored to the child, and regular health monitoring for the conditions that are more common — for example heart checks in babies, and ongoing checks of thyroid, hearing and vision. Any health conditions found are treated in their own right. Support for families, and for independence, work and relationships as the person grows, is central. Coordinated care and a focus on the person's strengths and goals make the biggest difference.
