What Is Down Syndrome?

 

Down Syndrome (also called Trisomy 21) is a genetic condition that happens when a person is born with an extra copy of chromosome 21.
This extra chromosome affects the way the body and brain develop.

People with Down Syndrome may:

  • Have mild to moderate learning disabilities,
  • Reach milestones (like walking and talking) more slowly,
  • Have some distinct facial features (such as almond-shaped eyes and a flat nose bridge),
  • Be more likely to have heart problems, hearing loss, or thyroid conditions,
  • Often have warm, caring personalities and strong social understanding.

Everyone with Down Syndrome is unique — their abilities and needs vary just like anyone else’s.

With the right health care, education, early support, and inclusion, people with Down Syndrome can lead happy, fulfilling lives, go to school and college, work, and take part in their communities.

Support may include:

  • Speech and language therapy
  • Occupational therapy
  • Inclusive learning environments
  • Health checks and community support groups

🌈 Easy Read Summary – Down Syndrome

💛 Down Syndrome (Trisomy 21)

  • People are born with one extra chromosome.
  • This can make learning and talking take longer.
  • People may have some health needs.
  • Everyone is different and special.

With the right help, people with Down Syndrome can 💛 What Is Down Syndrome?

Down Syndrome (also called Trisomy 21) is a genetic condition that happens when a person is born with an extra copy of chromosome 21.
This extra chromosome changes how the body and brain develop before birth.
It is one of the most common chromosomal differences, affecting around 1 in every 700 babies.


🧬 What Causes Down Syndrome?

Down Syndrome is not caused by anything the parents did or didn’t do.
It happens by chance when cells divide differently during early development.
There are three main types of Down Syndrome:

1.            Trisomy 21 – the most common, where every cell has an extra chromosome 21.

2.            Translocation – part of chromosome 21 attaches to another chromosome.

3.            Mosaicism – only some cells have the extra chromosome, often leading to milder effects.


🌼 Common Features and Strengths

People with Down Syndrome may share some physical features, such as:

  • Almond-shaped eyes
  • A small nose and flat nasal bridge
  • A single crease across the palm of the hand
  • Shorter height and smaller hands and feet

However, every person is different — no two people with Down Syndrome are the same.
Many have strong social and emotional awareness, a great sense of humour, and enjoy learning and taking part in community life.


💬 Learning and Development

Children with Down Syndrome usually have mild to moderate learning disabilities.
They may:

  • Learn to sit, walk, or talk later than others
  • Need more time to learn new skills
  • Benefit from clear structure, repetition, and visual learning
  • Respond well to encouragement and positive communication

Many people go on to attend mainstream schools, colleges, and workplaces.

  • live happy, full lives.

🩺 Health and Support Needs

Some people with Down Syndrome may have health conditions, such as:

  • Heart problems (especially early in life)
  • Hearing or vision difficulties
  • Thyroid issues
  • Low muscle tone (making movement slower)

Regular check-ups, early interventions, and therapies help manage these challenges.
Support may include:

  • Speech and language therapy
  • Physiotherapy and occupational therapy
  • Health monitoring and medical care
  • Educational support and inclusion planning

🌈 Living with Down Syndrome

People with Down Syndrome live longer, healthier, and more independent lives today than ever before.
With the right support, many:

  • Study and work
  • Live independently or with minimal support
  • Have strong friendships and relationships
  • Take part in sports, art, volunteering, and advocacy

There are many organisations that offer help and information, including:

  • Down’s Syndrome Association (UK) – www.downs-syndrome.org.uk
  • National Down Syndrome Society (US) – www.ndss.org
