DOWN SYNDROME

This is a genetic syndrome caused by having an extra copy of Chromosome 21. At conception, a fertilized egg usually has 23 pairs of chromosomes. In Down Syndrome there are 3 copies of genetic material on Chromosome 21. This changes the normal development of the brain and body.

  • Mild to moderate decrease in IQ

Typical physical signs of:

  • Flat face with an upward slant to the eyes, short neck, and abnormally shaped ears

  • Intestinal problems such as blocked small intestine or esophagus
  • Celiac disease (sensitivity to gluten)
  • Eye problems, such as cataracts
  • Thyroid dysfunctions
  • Skeletal problems
  • Dementia-similar to Alzheimer’s

 

Down Syndrome cannot be cured. However, there are interventions that can allow the child to function at their optimal level.

  • Speech, Occupational, and Physical therapies
  • Special education classes
