WHAT YOU NEED TO KNOW:
What is Down syndrome?
Down syndrome is a condition that occurs when a baby is born with an extra chromosome. Chromosomes are groups of genes that tell the body how to grow and function. This extra chromosome causes certain physical features and delays in physical and mental development. It also increases your child's risk of certain health problems. The cause of Down syndrome is not known. A woman's risk of having a baby with Down syndrome increases with age.
What are the physical features of Down syndrome?
Not all people with Down syndrome will have the same physical features. Your child may have any of the following:
- A flat face with an upward slant to the eyes
- A short neck, small ears, and a large tongue
- Small hands with single crease across the middle palm of the palm
- Small feet with a large space between the big and second toes
- Short pinky fingers that sometimes curve toward the thumb
How is Down syndrome diagnosed?
Screening tests can estimate your risk of having a baby with Down syndrome. Blood tests and ultrasounds are screening tests offered in the first and second trimesters of pregnancy. If your risk is high, healthcare providers will advise you to have diagnostic testing. Diagnostic tests can confirm that a baby has Down syndrome. You may have any of the following:
- Amniocentesis is done during the second trimester (16 to 18 weeks). A sample of the fluid surrounding the baby is taken to examine the chromosomes.
- Chorionic villus sampling is done during the first trimester (9 to 11 weeks). A sample of cells from the placenta is taken to examine the chromosomes.
- A chromosomal karyotype test after birth confirms Down syndrome in a newborn. A blood sample is taken from the baby to examine the chromosomes. Healthcare providers use this test along with examination of the baby's physical features to diagnose Down syndrome.
How may Down syndrome affect my child's health?
Your child may be born with the following conditions or develop them later in life:
- Heart defects
- Gastrointestinal problems, such as constipation, blocked intestine, or celiac disease
- Ear or sinus infections
- Skeletal problems, such as hip dislocation
- Hearing or vision problems
- Thyroid disease or blood disorders
- Obesity or sleep apnea
- Problems with memory, concentration, or judgment
- Speech or language delays
How can I help my child reach his physical and mental potential?
- Early intervention is a program of therapy, exercises, and activities that will help your child with developmental delays during his first 5 years. Early intervention may consist of occupational, physical, and speech therapy.
- Frequent checkups with your child's healthcare provider will be needed because he is at risk for medical conditions and developmental problems. Your child's healthcare provider will closely monitor his growth, development, and general health. Your child will need regular physical, hearing, and eye exams.
