What is Down Syndrome and what causes it?

  • In the body, chromosomes are discrete "packages" of genes. They control how a baby's body develops during pregnancy and after birth, determining how it will look and work. A newborn typically has 46 chromosomes (23 Chromosome Pairs). One of these chromosomes, chromosome 21, has an extra copy in infants with Down syndrome.
  • Thus, an extra chromosome causes the disorder known as Down syndrome.
  • Trisomy is the medical word for having an extra copy of a chromosome.
  • Trisomy 21 is another term used to describe Down syndrome.

Impact of Down Syndrome

  • The newborn may experience difficulties with their mental and physical development as a result of this additional copy, which alters how their body and brain grow.
  • Individuals with Down syndrome typically have mild to moderately low IQs (a measure of intelligence) and speak more slowly than other children.

Treatment

  • There's no cure for Down syndrome, but treatment is available to help the child reach their full potential.
  • Treatment focuses on helping your child thrive physically and mentally.
  • Treatment options could include: Physical or occupational therapy.
