Symptoms

Each person with Down syndrome is an individual — intellectual and developmental problems may be mild, moderate or severe. Some people are healthy while others have significant health problems such as serious heart defects.

Children and adults with Down syndrome have distinct facial features. Though not all people with Down syndrome have the same features, some of the more common features include:

Flattened face

Small head

Short neck

Protruding tongue

Upward slanting eye lids (palpebral fissures)

Unusually shaped or small ears

Poor muscle tone

Broad, short hands with a single crease in the palm

Relatively short fingers and small hands and feet

Excessive flexibility

Tiny white spots on the colored part (iris) of the eye called Brushfield's spots

Short height

Infants with Down syndrome may be average size, but typically they grow slowly and remain shorter than other children the same age.

Intellectual disabilities

Most children with Down syndrome have mild to moderate cognitive impairment. Language is delayed, and both short and long-term memory is affected.
