What are the signs of Down syndrome in babies?

What causes a baby to have a huge head?

Having a larger head size can be harmless, if a larger head size is a family trait, or it can be a sign of a serious medical condition. Common medical conditions include an enlarged brain, brain bleed, fluid on the brain and genetic disorders. Treatments are specific to the cause.

Can you tell if a newborn has Down syndrome?

Diagnostic tests can typically detect whether or not a baby will have Down syndrome, but they can be more risky for the mother and developing baby. Neither screening nor diagnostic tests can predict the full impact of Down syndrome on a baby; no one can predict this.

What is genetic syndrome with a big head?

Macrocephaly is the condition of having an abnormally large head, including the scalp, cranial bone, and intracranial content. The most common type is benign familial macrocephaly, but the condition also is associated with chromosomal anomalies and various phenotypic syndromes.

How often does Down syndrome go undiagnosed?

No. About eight or nine out of 10 cases of Down syndrome are detected (classified as screen positive). This means that one or two out of 10 pregnancies with Down syndrome are missed (classified as screen negative).

Do babies with Down syndrome measure small?

Genetic abnormalities such as trisomy 21 (Down syndrome) also tend to result in babies that are smaller compared with the general population.

Do autistic babies have big heads?

It has been known for 60 years that some autistic individuals, both children and adults, have unusually large heads. About 20 per cent are formally diagnosed with “macrocephaly,” which requires that a patient's head circumference measurement be in the highest two per cent for their age group.

(Not me, though, because I have a big head and I'll take any perceived genetic advantage I can get.)

What does a large head circumference indicate?

Children with macrocephaly have a head circumference (the measurement around the widest part of the head) that is greater than the 98th percentile. Sometimes a large head means that there is a problem in the brain which might require surgery.

What are the facial features of Down syndrome?

Some common characteristics present in people with the disorder include distinctive facial features, such as slanting eyes, small chin, round face, flat nasal bridge, Brushfield spots in the iris, abnormal outer ears, and flattened nose.

A pregnant person at age 25 has about a 1 in 1,250 chance of conceiving a child with Down syndrome. At age 40, the incidence becomes approximately 1 in 100.

How soon after birth can Down syndrome be detected?

Diagnostic tests for Down syndrome include: Chorionic villus sampling (also called CVS). This test checks tissue from the placenta to see if your baby has a genetic condition, like Down syndrome. You can get CVS at 10 to 13 weeks of pregnancy.

Are Down syndrome babies larger?

Height and weight — Babies with Down syndrome are usually smaller than other babies, and they have smaller heads. They may also grow more slowly and may never reach the same heights that typical children do.

Do Downs babies have short legs?

Compared to the length of their trunks, children with Down Syndrome have short arms and legs. This makes learning certain gross motor skills harder; for example, shorter legs make it harder to climb.

Do all Down syndrome babies have low muscle tone?

Almost all children with DS suffer from muscle hypotonia (MH), a state of reduced muscle tone, usually related to the skeletal muscles.

Can a child have a mild case of Down syndrome?

Each person with Down syndrome is an individual — intellectual and developmental problems may be mild, moderate or severe.

Why do Down syndrome have slanted eyes?

Slanting and a fold of skin (epicanthal fold) are normal in people of Asian descent. Abnormal slanting of the eye may occur with some genetic disorders and syndromes. The most common of these is Down syndrome. People with Down syndrome often also have an epicanthal fold in the inner corner of the eye.

Can a child have Down syndrome and not look like it?

Some of the children with Mosaic Down syndrome that we know do not actually look as if they have Down syndrome - the usual physical features are not obvious. This raises some important and difficult social issues and identity issues for both parents and children, which parents have discussed with us.

Do Down syndrome babies have puffy eyes?

Blepharitis (eyelid inflammation) – Children with Down syndrome have a higher rate of inflammation of the eyelids that can cause redness at the edge of the lids and crusting around the lashes.

Do Down syndrome babies cry differently?

Their smiles were also found to be shorter, and less discriminative between the two face-to-face conditions. The non-handicapped infants showed significantly more cry/distress vocalizations in the immobile than in the mobile condition, while the reverse was found for the Down's syndrome infants.

When should I be concerned about my baby's head size?

The simple definition of the word macrocephaly is "large head." Doctors apply that diagnosis when a baby's head size is in the 98th percentile. This means that the baby's head is bigger than 98% percent of other babies of the same age.
