Interesting Facts About Down Sydrome

  • 1. Down syndrome is usually identified at birth by the presence of certain physical traits: low muscle tone, a single deep crease across the palm of the hand, a slightly flattened facial profile and an upward slant to the eyes. Because these features may be present in babies without Down syndrome, a chromosomal analysis called a karyotype is done to confirm the diagnosis.
  • 2. People with Down syndrome have an increased risk for certain medical conditions such as congenital heart defects, respiratory and hearing problems. Many of these conditions are now treatable, so most people with Down syndrome can still lead healthy lives.
  • 3. People with Down syndrome have feelings just like anyone else. They experience the full range of emotions. They respond to positive expressions of friendship and are hurt and upset by inconsiderate behavior.
