On this page, you can find everything you are looking for regarding Down syndrome.
What Is Down Syndrome?
Down syndrome, or trisomy 21, is a condition where the affected person has an additional chromosome compared to an unaffected person. This results in abnormal development of the body and brain, which can lead to mental and physical challenges for the child.
Chromosomes are small "bundles" of genes in the body that determine how a child's body forms and functions during and after pregnancy.
Although people with Down syndrome may exhibit similar behaviors and appearances, each individual has different abilities.
What Are the Symptoms of Down Syndrome?
Some common physical traits of Down syndrome include:
A flat face, especially the nose
Almond-shaped, slanted eyes
Short neck
Small ears
A tongue that tends to stick out of the mouth
Small white spots on the iris of the eye (the colored part)
Small hands and feet
A single crease across the palm of the hand
Small pinky fingers that sometimes curve toward the thumb
Poor muscle tone or loose joints
Shorter stature than other children and adults
Some common cognitive traits of Down syndrome include:
An IQ (intelligence measure) within a low to moderate range compared to other children
Slower speech development than other children
Other health issues include:
Hearing loss
Obstructive sleep apnea, a condition where breathing temporarily stops during sleep
Ear infections
Eye diseases
Congenital heart defects
What Are the Causes of Down Syndrome?
The exact cause of the syndrome is not known, nor are the various factors that play a role in its occurrence, but a significant factor that increases the risk of having a child with Down syndrome is the mother's age. Women who are 35 years old or older are more likely to have a child with Down syndrome compared to younger mothers.
What Are the Diagnostic Methods?
A doctor will take a medical history and perform a clinical examination. Additional procedures may be requested as needed, such as:
Laboratory tests of blood and ultrasound scans during pregnancy
Diagnostic tests during pregnancy decided by the doctor when there is a likelihood of the fetus having Down syndrome to confirm the diagnosis. This may involve sampling from the uterus, whether of fluid or villi, but it could be riskier for the mother and fetus.
Genetic testing of the child after birth to confirm the genetic defect causing Down syndrome
What Are the Treatment Methods for Down Syndrome?
Down syndrome is a lifelong condition. Early care and provision of services for children and infants with Down syndrome often improve their physical and cognitive abilities. Most of these services focus on helping children with Down syndrome develop their full potential. Care services include speech therapy, occupational therapy, and physical therapy. Children with Down syndrome may also require additional help or attention in school.
What Are the Preventive Methods for Down Syndrome?
There are no known methods to prevent the syndrome.
What Are the Complications of Down Syndrome?
There are other health problems associated with Down syndrome that require medical care and regular check-ups, such as:
Hearing problems
Ear infections
Vision problems
Congenital heart defects
Obstructive sleep apnea
When Should You See a Doctor?
A pregnant woman should consult her doctor at all stages of pregnancy for advice and regular check-ups, and after delivery, if some distinctive signs of Down syndrome are observed in the child, or if the child's growth is delayed compared to peers of the same age.
Frequently Asked Questions
Is Down syndrome a hereditary disease?
No, Down syndrome is not a hereditary condition, but a genetic disorder occurring for unknown reasons, with one of the main factors being the mother's age during pregnancy, as the likelihood of the genetic disorder increases if the mother is over 35 years old.
Is Down syndrome a chronic disease that cannot be cured?
Down syndrome is a chronic condition that cannot be cured, but healthcare is provided to avoid complications associated with the condition.
