What Do Babies at Two Month Olds With Down Syndrome Do

Down syndrome is a status in which a person has an actress chromosome.

What is Down Syndrome?

Down syndrome is a status in which a person has an actress chromosome. Chromosomes are pocket-sized "packages" of genes in the body. They make up one's mind how a baby's trunk forms and functions every bit it grows during pregnancy and after birth. Typically, a baby is born with 46 chromosomes. Babies with Downwards syndrome have an extra copy of one of these chromosomes, chromosome 21. A medical term for having an extra copy of a chromosome is 'trisomy.' Down's syndrome is also referred to every bit Trisomy 21. This extra copy changes how the baby's torso and brain develop, which can cause both mental and physical challenges for the baby.

Even though people with Down syndrome might human activity and look like, each person has different abilities. People with Down syndrome usually have an IQ (a measure of intelligence) in the mildly-to-moderately depression range and are slower to speak than other children.

Some common physical features of Down syndrome include:

• A flattened confront, especially the bridge of the nose
• Almond-shaped eyes that camber upward
• A brusk neck
• Small ears
• A tongue that tends to stick out of the mouth
• Tiny white spots on the iris (colored function) of the eye
• Small hands and anxiety
• A single line across the palm of the mitt (palmar crease)
• Small pinky fingers that sometimes curve toward the thumb
• Poor muscle tone or loose joints
• Shorter in peak equally children and adults

How Many Babies are Born with Down Syndrome?

Downwardly syndrome remains the about common chromosomal condition diagnosed in the The states. Each year, near six,000 babies built-in in the United states of america have Down syndrome. This means that Down syndrome occurs in nigh ane in every 700 babies.¹

Types of Down's syndrome

At that place are 3 types of Down syndrome. People oftentimes can't tell the difference between each type without looking at the chromosomes because the concrete features and behaviors are similar.

• Trisomy 21: About 95% of people with Down's syndrome take Trisomy 21.² With this type of Downwardly syndrome, each cell in the body has 3 separate copies of chromosome 21 instead of the usual 2 copies.
• Translocation Down's syndrome: This type accounts for a small percentage of people with Down syndrome (about 3%).² This occurs when an extra part or a whole extra chromosome 21 is present, but it is attached or "trans-located" to a dissimilar chromosome rather than existence a separate chromosome 21.
• Mosaic Down syndrome: This blazon affects about 2% of the people with Downward syndrome.² Mosaic means mixture or combination. For children with mosaic Down syndrome, some of their cells have iii copies of chromosome 21, just other cells have the typical two copies of chromosome 21. Children with mosaic Down's syndrome may have the aforementioned features as other children with Downward syndrome. Notwithstanding, they may accept fewer features of the status due to the presence of some (or many) cells with a typical number of chromosomes.

Causes and Risk Factors

• The actress chromosome 21 leads to the physical features and developmental challenges that can occur amidst people with Down's syndrome. Researchers know that Down syndrome is caused by an extra chromosome, just no ane knows for sure why Down syndrome occurs or how many different factors play a function.
• One cistron that increases the risk for having a babe with Downward syndrome is the mother's age. Women who are 35 years or older when they get meaning are more than likely to have a pregnancy affected by Down's syndrome than women who become pregnant at a younger age.^3-fiveHowever, the majority of babies with Down's syndrome are born to mothers less than 35 years one-time, because at that place are many more than births amidst younger women.^vi,seven

Diagnosis

There are ii basic types of tests bachelor to detect Down syndrome during pregnancy: screening tests and diagnostic tests. A screening test can tell a woman and her healthcare provider whether her pregnancy has a lower or higher run a risk of having Down syndrome. Screening tests do not provide an absolute diagnosis, but they are safer for the mother and the developing infant. Diagnostic tests can typically detect whether or not a baby will have Down syndrome, but they can exist more risky for the female parent and developing babe. Neither screening nor diagnostic tests tin can predict the full touch on of Down syndrome on a baby; no one can predict this.

Screening Tests

Screening tests often include a combination of a blood test, which measures the amount of various substances in the mother's blood (e.chiliad., MS-AFP, Triple Screen, Quad-screen), and an ultrasound, which creates a moving picture of the babe. During an ultrasound, one of the things the technician looks at is the fluid backside the baby's neck. Extra fluid in this region could indicate a genetic problem. These screening tests can assistance determine the baby's chance of Down syndrome. Rarely, screening tests tin can give an abnormal effect fifty-fifty when there is zilch wrong with the baby. Sometimes, the test results are normal and even so they miss a problem that does exist.

Diagnostic Tests

Diagnostic tests are usually performed after a positive screening examination in gild to confirm a Down syndrome diagnosis. Types of diagnostic tests include:

• Chorionic villus sampling (CVS)—examines material from the placenta
• Amniocentesis—examines the amniotic fluid (the fluid from the sac surrounding the babe)
• Percutaneous umbilical blood sampling (PUBS)—examines blood from the umbilical cord

These tests look for changes in the chromosomes that would indicate a Down syndrome diagnosis.

Other Health Problems

Many people with Downwardly syndrome accept the common facial features and no other major nativity defects. However, some people with Down syndrome might accept one or more major birth defects or other medical problems. Some of the more common health problems amid children with Down syndrome are listed below.⁸

• Hearing loss
• Obstructive slumber apnea, which is a status where the person'south breathing temporarily stops while asleep
• Ear infections
• Eye diseases
• Center defects present at birth

Health care providers routinely monitor children with Down's syndrome for these conditions.

Treatments

Down syndrome is a lifelong status. Services early in life will often help babies and children with Down's syndrome to amend their physical and intellectual abilities. Most of these services focus on helping children with Down syndrome develop to their full potential. These services include voice communication, occupational, and concrete therapy, and they are typically offered through early intervention programs in each state. Children with Down syndrome may also need extra help or attending in schoolhouse, although many children are included in regular classes.
