Edwards’ Syndrome, also known as Trisomy 18, is a genetic disorder caused by the presence of all or part of an extra 18th chromosome. This condition often disrupts normal development and can cause slow growth in the uterus, a low birth weight, and many medical complications.
Among the many symptoms, individuals with Edwards’ Syndrome might have heart defects, intellectual and developmental delays, small head size, abnormally shaped head, small mouth and jaw, clenched fists with overlapping fingers, underdeveloped fingernails, and kidney problems.
Some cases are life-threatening, with only 5-10% of babies surviving beyond their first year. However, with careful management of their health conditions, a small number of individuals can live into adulthood. Detection of Edwards’ Syndrome can be done prenatally through screening tests.
It’s important to note that there’s no cure for Edwards’ Syndrome. Management of the condition mainly involves providing supportive care. This may involve surgery for life-threatening heart defects, therapy for developmental issues, nutritional support, breathing assistance, and managing any other health complications as they arise.
Causes of Edwards’ syndrome
Edwards syndrome, also known as Trisomy 18, is a genetic disorder caused by the presence of an extra 18th chromosome. Most often, it occurs due to a random event during the formation of the reproductive cells (egg and sperm). An error in cell division, known as non-disjunction, can result in reproductive cells having an abnormal number of chromosomes.
In most cases of Edwards syndrome, the person has three copies of chromosome 18 instead of the usual two (trisomy). Some people possess the additional chromosome in only some of their cells, which is known as mosaicism.
In a small percentage of cases, a piece of chromosome 18 becomes attached to another chromosome before or after conception. Individuals with this rare type of genetic change are said to have “partial trisomy 18”.
The additional genetic material from chromosome 18 interrupts the typical development, leading to the characteristic signs and symptoms of Edwards syndrome. It’s important to note that Edwards syndrome is not caused by anything the parents did or did not do either before or during pregnancy.
Risk Factors of Edwards’ syndrome
Edwards Syndrome, also known as Trisomy 18, is a chromosomal disorder caused by the presence of all or part of an extra 18th chromosome.
The exact cause of the disorder isn’t known but we know that it’s mostly random and not caused by anything parents did or didn’t do. However, there are certain risk factors associated with it:
1. Maternal Age: The most significant risk factor is advanced maternal age. As the mother’s age increases, especially after the age of 35, the risk of having a child with Edwards Syndrome also increases.
2. Previous Trisomy Conditions: If a woman has had a child with a trisomy condition in the past, she is also at a higher risk of having a child with Edwards Syndrome.
3. Genetic Translocation: In rare cases, the syndrome can also occur due a balanced translocation in a parent. This is where a segment from one chromosome (chromosome 18 in this case) has swapped places with a segment from another chromosome. This doesn’t normally cause any health problems, but it can increase the risk of having a child with conditions like Edwards’ syndrome.
4. Parental exposure to environmental toxins: Although not directly correlated, like all pregnancies, the exposure to certain environmental toxins may increase the risk of genetic anomalies.
5. Edwards syndrome is not usually inherited, but rather, occurs randomly during the formation of reproductive cells.
Generally, it’s important to remember that while these risk factors can increase the risk of having a child with Edwards Syndrome, it’s theoretically possible for anyone to have a child with the condition. It’s therefore crucial for expecting parents, especially those with known risk factors, to avail of prenatal screening tests.
Signs and Symptoms of Edwards’ syndrome
Edwards Syndrome, also known as Trisomy 18, is a genetic disorder caused by the presence of all or part of an extra 18th chromosome. The condition often results in severe intellectual and developmental issues.
Here are some common signs and symptoms associated with Edwards Syndrome:
1. Growth Deficiency: Babies with Edwards Syndrome usually experience significant developmental delays. They tend to have a low birth weight and may continue to grow and develop slowly after birth.
2. Distinct Facial Features: These can include a small head (microcephaly), small jaw (micrognathia), low-set ears, wide-set eyes, a small mouth, and a short neck.
3. Physical Abnormalities: These might encompass clenched fists with overlapping fingers, clubfeet, a small pelvis with limited hip movements, and underdeveloped lungs and heart.
4. Heart Defects: Majority of children with Edwards syndrome have congenital heart defects, which might vary from minor to serious conditions.
5. Kidney Problems: Malformations in kidneys and urinary tract are also common.
6. Neurological Issues: Severe developmental delays and intellectual disability are almost always part of the syndrome.
7. Feeding Difficulties: Infants with this condition often have trouble feeding due to problems with sucking or swallowing.
8. Respiratory Problems: Breathing issues, often caused by underdeveloped lungs or heart defects, are common in individuals with this syndrome.
This list covers common signs and symptoms associated with Edwards Syndrome. Depending on the severity and type of disorder (full or partial trisomy), symptoms and prognosis may vary. Please, consult with a healthcare professional or genetic counselor for precise and comprehensive understanding of this condition.
Diagnosis Edwards’ syndrome
Edwards’ syndrome, also known as Trisomy 18, is a chromosomal condition associated with abnormalities in many parts of the body. It’s caused by an error in cell division known as meiotic disjunction. When this happens, you end up with three copies of chromosome 18 in each cell of the body, instead of the usual two.
Individuals with Edwards’ syndrome often have slow growth before birth (intrauterine growth retardation) and a low birth weight followed by feeding difficulties, breathing problems and developmental delay. Other signs include a small, abnormally shaped head; a small jaw and mouth; and clenched fists with overlapping fingers.
Serious heart defects are common in children with Trisomy 18, along with other medical conditions such as kidney problems and intestinal abnormalities.
The severity of Edwards’ syndrome varies, and in some cases, individuals may live for several weeks or months while others may live into adulthood. However, this is very rare and generally, Edwards’ syndrome seriously reduces life expectancy.
Pregnant women may be offered screening for Edwards’ syndrome as part of their prenatal care. This can help identify if the unborn baby is at risk. If further testing confirms the diagnosis, parents can be prepared for the challenges to come and make informed decisions about the care of their child.
Treatment of Edwards’ syndrome
Edwards Syndrome, also known as Trisomy 18, is a genetic disorder that causes a variety of physical and mental challenges. It is caused by an extra copy of chromosome 18.
As of now, there is no specific cure or treatment for Edwards Syndrome. The approach to treatment usually involves managing the symptoms and improving the quality of life of the individual.
The treatment strategies may include:
1. Heart Defect Treatment: Many individuals with Trisomy 18 have heart defects that might need treatment, including medications or surgery.
2. Respiratory Therapy: Breathing difficulties can be managed with the help of respiratory therapy or tracheostomy in severe cases.
3. Physical Therapy: Physical therapy and occupational therapy can help manage movement problems and improve muscle strength and coordination.
4. Feeding Support: Many babies with Edwards Syndrome have difficulties feeding; they might need a gastrostomy tube to help with feeding and nutrition.
5. Palliative Care: This includes using medication, nutritional adjustments, physical therapy, and surgical interventions to treat symptoms and improve the individual’s quality of life.
6. Supportive care: This includes comfort and care provided to the children that enhances quality of life. Emotional support to the families and educating them about the condition are also vital parts of support.
Again, it’s important to understand that these are general strategies and the specific treatment plan will depend on the individual’s symptoms and overall health status. Any treatment or management approach should be under the guidance of a medical professional.
Medications commonly used for Edwards’ syndrome
Edwards Syndrome, also known as Trisomy 18, is a genetic disorder caused by an extra copy of the 18th chromosome. This condition typically causes severe intellectual and physical disabilities, hence treatments usually focus on managing the symptoms or complications. Medications used can vary greatly based on the specific symptoms a patient is experiencing.
1. Cardiovascular Medications: Many children with Edwards Syndrome have congenital heart defects. They may be prescribed medications to help their heart function more effectively, such as beta-blockers or digoxin.
2. Anticonvulsant Medications: Some children may experience seizures and may therefore be prescribed anticonvulsant medications.
3. Nutritional Supplements: Infants may have difficulties with feeding due to physical abnormalities. In some cases, nutritional supplements or a specialized diet may be necessary.
4. Antibiotics: Due to their weak immune system, these individuals are often more susceptible to respiratory and other infections. Antibiotics are commonly used to treat or prevent these infections.
5. Pain Relief: Analgesics may be given to alleviate any discomfort or pain, particularly in the case of surgical interventions or chronic conditions.
The main intent of medication use in individuals with Trisomy 18 is to alleviate symptoms or complications, rather than to treat the underlying disorder.
Prevention of Edwards’ syndrome
Edwards Syndrome, also known as Trisomy 18, is a genetic condition where a person has an extra 18th chromosome. This condition is typically not preventable, as it usually occurs randomly during the formation of reproductive cells. However, there are steps you can take to decrease the risk of having a child with Edwards Syndrome or to detect the condition earlier.
1. Advanced Maternal Age: The risk of having a child with Edwards Syndrome increases as a woman gets older, especially after age 35. Therefore, advanced maternal age can be a risk factor. Women who are planning to have a child later in life may want to consider genetic counseling to understand their chances of having a child with a chromosomal disorder.
2. Regular Prenatal Screening: Prenatal screening can detect the presence of trisomy 18 through tests such as ultrasound scans, maternal serum screening, and invasive diagnostic procedures like amniocentesis or chorionic villus sampling (CVS).
3. Preimplantation Genetic Diagnosis: For families at risk of chromosomal disorders, preimplantation genetic diagnosis (PGD) may be an option. This involves in-vitro fertilization (IVF), with the embryos being tested for genetic conditions before they are implanted in the womb.
4. Genetic Counseling: If you have a family history of Edwards Syndrome, or if you’re planning a pregnancy and are concerned about your chances of having a child with Edwards Syndrome, a genetic counselor can provide useful information.
5. Healthy Lifestyle: Although Edwards Sydrome is not caused by lifestyle factors, maintaining a healthy lifestyle during pregnancy can always prove to be beneficial for general well-being.
Remember, none of these steps guarantee the prevention of Edwards Syndrome, but they can help identify the syndrome early or decrease the risk. All decisions about prenatal tests, especially if you’re at risk, should be made in consultation with your doctor or a genetic counselor.

Complications of Edwards’ syndrome
Edwards’ Syndrome, also known as Trisomy 18, arises from a chromosomal abnormality where a person has three copies of chromosome 18 instead of the normal two. This extra genetic material causes a range of severe mental and physical complications. Here are a few:
1. Growth Problems: Babies with Edwards’ Syndrome usually have lower birth weight and growth issues, both before and after birth.
2. Developmental Delays: There are usually severe developmental delays, both physically and mentally. Some children never learn to sit up, walk, or achieve other cognitive milestones.
3. Physical Abnormalities: Babies may have a small head, small jaw, low-set ears, clenched hands, underdeveloped thumbs and nails, foot deformities, and a small chest with short ribs.
4. Congenital heart defects: More than half of babies with Edwards’ syndrome have heart defects, ranging from severe conditions that affect blood flow to minor defects that do not need treatment.
5. Kidney Problems: These can range from minor structural abnormalities to a complete absence of one or both kidneys.
6. Breathing and Eating Difficulties: Babies frequently have difficulty eating and gaining weight due to complications with sucking and swallowing. As a result, many babies with Edwards’ syndrome require tube feeding.
7. Increased Infections: There’s an increased risk of respiratory and urinary tract infections.
8. Short Lifespan: Because of the multiple systemic abnormalities, many individuals with Trisomy 18 die before birth or within their first month. Only a small percentage of children survive beyond the first year, and often with considerable healthcare needs, involving significant medical intervention.
It’s also important to note that the syndrome varies greatly among individual infants. Some babies may have more severe health problems or physical abnormalities than others.
Home remedies of Edwards’ syndrome
Edwards Syndrome, also known as Trisomy 18, is a genetic disorder caused by having an extra 18th chromosome. The disease is characterized by severe physical and mental disabilities. Unfortunately, Edwards Syndrome is not curable, and treatments are largely supportive and preventive in nature.
There are no known home remedies that can treat or prevent this disorder. The treatment usually involves managing symptoms and improving quality of life. Medical treatments and interventions may vary from patient to patient, depending on the individual case’s severity and complexity.
In most cases, infants with Edwards Syndrome require a team of healthcare specialists to address their various health needs, including specialists in genetics, cardiology, gastroenterology, and more. Parents and caregivers have the pivotal role to provide continuous home care, which could include:
1. Comfortable bedding and clothing
2. Regularly scheduled feeding and sleeping timetable
3. Extra care for babies with heart conditions, feeding difficulties, or breathing problems
4. Regular hospital check-ups
Emotional support, both for the child and the family, is crucial to manage this challenging condition. It may be beneficial to seek help from support groups or counseling services to cope with the emotional toll such a diagnosis often brings.
However, it’s important to note that any treatment or care plan should be established with the guidance of a medical professional.
Additionally, genetic counseling may be recommended to understand the disease’s inheritance pattern and to make informed decisions about future pregnancies.
