Open spinal dysraphism with a myelomeningocele is a birth condition in which part of the spine and spinal cord do not close fully before birth. It is usually recognized during pregnancy or at birth, and people with open spinal dysraphism with a myelomeningocele may have leg weakness, changes in bladder or bowel control, and fluid buildup around the brain. The condition is lifelong, but surgery soon after birth and ongoing care can help protect the spinal tissue and support mobility, learning, and daily health. Not everyone will have the same experience. Survival has improved greatly with modern care, though health risks and long-term outlook depend on how severe the early signs of open spinal dysraphism with a myelomeningocele are and whether complications develop.
How many people live with Open spinal dysraphism with a myelomeningocele?
Worldwide, about 0.8 million people are living with spina bifida (Global Burden of Disease Study 2021); because myelomeningocele, the most common open form, is estimated to make up roughly 75% to 90% of cases depending on how spina bifida types are grouped, this suggests about 0.6 to 0.7 million people worldwide are living with myelomeningocele, although that is an estimate rather than a direct count. In the United States, about 166,000 people are living with spina bifida (CDC, 2024); using the same range, roughly 125,000 to 149,000 may be living with myelomeningocele, again as an estimate rather than a direct count.
Overview
Open spinal dysraphism with a myelomeningoceleSymptoms
Open spinal dysraphism with a myelomeningocele is usually noticed at birth. Features often include a sac on the back, weakness or paralysis in the legs, and trouble with bladder or bowel control. Some babies also develop hydrocephalus, which is extra fluid around the brain.
Outlook and prognosis
With open spinal dysraphism with a myelomeningocele, outlook varies mainly with the level of the spinal opening and brain or bladder problems. Many living with open spinal dysraphism with a myelomeningocele reach adulthood, though ongoing support for movement, continence, and learning is often needed.
Causes and risk factors
Open spinal dysraphism with a myelomeningocele usually begins before birth, when the neural tube does not close fully. Risk can be higher with folate deficiency, certain seizure medicines, diabetes, obesity, high early-pregnancy heat exposure, and sometimes inherited susceptibility.
Genetic influences
Genetics can play a part in open spinal dysraphism with a myelomeningocele, but it is usually not caused by a single gene change. Many small genetic variations, together with factors like low folate before and early in pregnancy, may raise risk.
Diagnosis
Open spinal dysraphism with a myelomeningocele is often recognized before birth on prenatal ultrasound. After birth, doctors diagnose it from visible spinal findings and a neurological exam. Imaging, usually MRI, helps confirm the diagnosis of open spinal dysraphism with a myelomeningocele.
Treatment and drugs
Treatment for open spinal dysraphism with a myelomeningocele often starts with surgery soon after birth to protect the spinal cord and lower infection risk. Ongoing care may include bladder and bowel support, physical therapy, mobility aids, and treatment for hydrocephalus.
Symptoms
Open spinal dysraphism with a myelomeningocele can affect movement, feeling, and bladder and bowel control from birth. The early features of open spinal dysraphism with a myelomeningocele are often visible right away, but how much they affect daily life depends on where the opening is along the spine and how much the nerves are involved. Features vary from person to person and can change over time as a child grows.
Many babies are born with a sac or open area over the spine, often in the lower back. This area may contain spinal cord tissue and nerves, so it needs urgent medical care to help lower the risk of infection and further nerve damage.
Weakness in the legs can range from mild foot weakness to little or no movement below the level of the spinal opening. This can affect standing, balance, walking, and whether someone needs braces, a walker, or a wheelchair.
Some people with open spinal dysraphism with a myelomeningocele have less feeling in the feet, legs, or lower body. Because pain or pressure may be harder to notice, skin sores, burns, and other injuries can happen more easily.
Open spinal dysraphism with a myelomeningocele often affects the nerves that help the bladder store and empty urine. This can lead to leaking, trouble emptying fully, repeated urinary tract infections, and kidney problems if it is not managed well.
How people usually first notice Open spinal dysraphism with a myelomeningocele?
Open spinal dysraphism with a myelomeningocele is usually first noticed before birth on a prenatal ultrasound or soon after delivery, when doctors see a sac or open area on the baby’s back where the spine did not close fully. The first signs of open spinal dysraphism with a myelomeningocele can also include weakness or less movement in the legs, changes in foot position, or problems with bladder and bowel control, although the exact pattern can vary depending on where the opening is along the spine. For many families, how open spinal dysraphism with a myelomeningocele is first noticed is through these visible findings at birth, followed by imaging tests that confirm the diagnosis and help guide urgent care.
Types of Open spinal dysraphism with a myelomeningocele
No distinct types of open spinal dysraphism with a myelomeningocele are widely recognized.
Can I slow down the onset of symptoms?
No. Open spinal dysraphism with a myelomeningocele is a problem of the spine and spinal cord that forms very early in pregnancy and is already present at birth, so there is no proven lifestyle change or medicine that can delay the start of symptoms once it has developed; care is aimed at early treatment and lowering complications, not delaying onset. For future pregnancies, taking folic acid before pregnancy and in early pregnancy is well known to lower the chance of this type of birth defect, but that lowers risk rather than preventing symptoms in a baby who already has it; even so, early specialist care can still make a meaningful difference in day-to-day health and comfort.
What genetics can tell you about symptoms
In open spinal dysraphism with a myelomeningocele, genetics can help explain why the condition happens, but they usually do not predict exactly which symptoms someone will have day to day. The symptoms and how severe they are are driven mostly by where the spinal opening is, how much the nerves are affected, and whether related problems such as hydrocephalus occur, although inherited differences may slightly influence overall risk and, in some cases, severity. In most families, genetic testing cannot reliably tell when symptoms will begin, because this condition is present before birth and its effects vary widely from one child to another.
Causes and risk factors
In open spinal dysraphism with a myelomeningocele, the spine and tissues around the spinal cord do not close fully very early in pregnancy. This is usually linked to a mix of genetic susceptibility and early pregnancy exposures, rather than one single cause. It’s rarely just one factor—it’s the mix that matters. Risk can be higher with too little folic acid before conception and in early pregnancy, certain anti-seizure medicines such as valproate, diabetes, obesity, or high body heat from fever or frequent hot tub use in the first weeks of pregnancy. A family history of neural tube defects can also raise the chance, and folic acid before and during early pregnancy can help lower the risk.
What are the most common causes or risk factors?
Open spinal dysraphism with a myelomeningocele usually happens very early in pregnancy, when the baby’s spine and spinal cord do not close all the way, and it is most often linked to a mix of inherited risk and early pregnancy factors rather than one single cause. The strongest known risk factors are not getting enough folic acid before pregnancy and in the first weeks after conception, having a previous pregnancy or close family history of a similar spine problem, and taking certain anti-seizure medicines, especially valproate. Poorly controlled diabetes, obesity before pregnancy, and high body temperature in early pregnancy, such as from a fever or frequent hot tub or sauna use, can also raise the risk.
Environmental and biological risk factors
Open spinal dysraphism with a myelomeningocele begins very early in pregnancy, often before someone realizes they are pregnant. The main risk factors for open spinal dysraphism with a myelomeningocele involve body-based conditions in the pregnant parent and certain early exposures that can affect neural tube closure. Doctors often group risks into internal (biological) and external (environmental).
Low folate levels around conception and in the first weeks of pregnancy are one of the strongest risk factors. Folate is needed for the neural tube to close normally, so too little can raise the chance of open spinal dysraphism with a myelomeningocele.
Low vitamin B12 or conditions that reduce folate absorption can also increase risk. These problems may leave too little of the nutrients needed for early neural tube closure.
Preexisting diabetes, especially when blood sugar is high early in pregnancy, raises the risk of neural tube defects. This can affect embryo development during the first weeks, often before pregnancy is recognized.
Higher body weight before pregnancy is linked to a greater risk of neural tube defects, including open spinal dysraphism with a myelomeningocele. The exact reason is not fully understood, but changes in metabolism and inflammation may play a role.
Genetic risk factors
When a baby is born with open spinal dysraphism with a myelomeningocele, families often want to know whether it was inherited. The genetic causes of open spinal dysraphism with a myelomeningocele are usually complex; it is usually a combination of inherited influences rather than one clear cause. Some families have a higher chance because of shared genes, and a smaller number of cases happen as part of a broader genetic syndrome or chromosome difference.
Polygenic background: Most cases do not come from one single gene change. Instead, many small inherited DNA differences likely add up and affect how the spine and nervous system form very early in pregnancy.
Family history: Having a parent, sibling, or close relative with a neural tube defect raises the chance somewhat. This suggests that shared genes in a family can increase risk, although most relatives will never have the condition.
Repeat pregnancy: If one pregnancy was affected by open spinal dysraphism with a myelomeningocele or a related neural tube defect, the chance is higher in a later pregnancy than in the general population. The exact level of risk can vary depending on the family pattern and whether a broader genetic condition is involved.
Chromosome changes: A small number of cases are linked to extra or missing chromosome material, or to larger DNA changes. When this is the cause, there are often other birth differences or growth concerns along with the spinal finding.
Rare syndromes: Rare inherited syndromes can include open spinal dysraphism with a myelomeningocele as one feature. In these cases, doctors may also notice a pattern of differences involving the brain, kidneys, limbs, or facial development that points to a broader genetic condition.
Lifestyle risk factors
Open spinal dysraphism with a myelomeningocele is present from birth, so lifestyle habits do not cause it. However, how lifestyle affects open spinal dysraphism with a myelomeningocele can be important for mobility, skin protection, bladder and bowel care, and the risk of complications over time. Daily routines often influence pressure injuries, infections, pain, and overall independence.
Regular, adapted movement can help maintain strength, joint range, and cardiovascular fitness in people with myelomeningocele. It may also support transfers, wheelchair skills, balance, and participation in daily life. Long periods of inactivity can worsen deconditioning and increase contracture risk.
Excess body weight can place more strain on weak muscles and joints and make walking, bracing, or wheelchair mobility harder. It can also raise the risk of skin breakdown in pressure areas and complicate transfers and self-care. Balanced eating and activity can therefore affect day-to-day function.
Poor pressure relief habits, prolonged sitting, and not checking the skin regularly can increase the risk of pressure sores, especially when sensation is reduced. Careful positioning, cushion use, and daily skin inspection can lower the chance of ulcers and secondary infection. This is one of the most important lifestyle risk factors for open spinal dysraphism with a myelomeningocele.
Inconsistent catheterization routines, low fluid intake, or poor hygiene can raise the risk of urinary tract infections and kidney complications. Following the bladder program closely can help protect urinary health and reduce incontinence episodes. Delaying care when symptoms change may allow problems to progress.
Risk prevention
Open spinal dysraphism with a myelomeningocele develops very early in pregnancy, so prevention is mainly about lowering the chance of it happening before conception and in the first weeks after. The most effective step is getting enough folic acid before pregnancy starts and continuing it early on, because many people do not know they are pregnant yet when the spine is forming. Prevention is about lowering risk, not eliminating it completely. For families who have had a pregnancy affected by open spinal dysraphism with a myelomeningocele, care before a future pregnancy can also help guide the safest next steps.
Taking folic acid every day before pregnancy and during early pregnancy can greatly lower the risk of open spinal dysraphism with a myelomeningocele. This matters most in the month before conception and through the first 4 weeks, when the spinal cord is closing.
Some people need a higher folic acid dose, especially after a previous pregnancy affected by open spinal dysraphism with a myelomeningocele or with certain medical conditions. Talk to your doctor before trying to conceive so the dose is tailored to your risk.
A pre-pregnancy checkup can help review medicines, health conditions, and family history that may affect risk. Doctors talk about primary prevention, meaning steps taken before a condition starts.
Some anti-seizure medicines and a few other drugs can raise the risk of neural tube defects, including open spinal dysraphism with a myelomeningocele. Do not stop prescribed medicine on your own, but ask whether a safer option is possible before pregnancy.
Can you prevent Open spinal dysraphism with a myelomeningocele?
This type of open spinal birth difference cannot always be prevented, but the risk can sometimes be lowered. The best-proven step is getting enough folic acid before pregnancy and during the first weeks of pregnancy, and for some people, good diabetes control and reviewing certain medicines with a doctor before pregnancy may also help reduce risk. Even when people do everything right, this condition can still happen.
Transmission
Open spinal dysraphism with a myelomeningocele, a form of spina bifida, is not contagious and cannot be passed from one person to another through touch, the air, sex, or shared food. Instead, how Open spinal dysraphism with a myelomeningocele is inherited is more complex, and it usually reflects a mix of genetic susceptibility and factors affecting early pregnancy rather than a single gene being directly passed from parent to child.
Many living with Open spinal dysraphism with a myelomeningocele are the first in their family to have it, so a family history is often absent. If a family has had one affected pregnancy, the chance in a future pregnancy is somewhat higher than average, which is why doctors often discuss folic acid before pregnancy and, in some cases, genetic counseling.
When to test your genes
For open spinal dysraphism with a myelomeningocele, genetic testing is not usually the main tool for early detection or day-to-day care. It may be worth discussing with a genetics team if there are other birth differences, a family history of neural tube defects, or a pregnancy affected before, because that can help clarify recurrence risk and guide future pregnancy planning.
Diagnosis
Open spinal dysraphism with a myelomeningocele is often identified before birth or right after delivery because the spine and nearby nerves do not form in the usual way. Diagnosis usually starts with visible physical findings and imaging tests that show how much of the spinal cord and surrounding tissues are involved. Getting a diagnosis is often a turning point toward answers and support. The genetic diagnosis of open spinal dysraphism with a myelomeningocele is not usually based on one single gene test, so doctors mainly rely on prenatal screening, imaging, and the baby’s clinical features.
Many cases are first suspected during pregnancy on a routine ultrasound. Doctors may see changes in the spine, brain, or the fluid-filled sac on the back that suggest open spinal dysraphism with a myelomeningocele.
A blood test during pregnancy may show a higher level of alpha-fetoprotein, which can be a clue that the baby has an open spinal defect. This result does not confirm the condition on its own, so it is paired with imaging.
If ultrasound findings are unclear or doctors need more detail, fetal MRI can show the spinal lesion and nearby structures more clearly. This helps define the level of the defect and can support the diagnosis of open spinal dysraphism with a myelomeningocele.
After birth, doctors examine the baby’s back for an open lesion or sac, along with leg movement, reflexes, and signs of bladder or bowel nerve involvement. The location and appearance of the lesion often make the diagnosis clear.
How is Open spinal dysraphism with a myelomeningocele diagnosed?
Open spinal dysraphism with a myelomeningocele is often found during pregnancy on a routine ultrasound, and a blood test during pregnancy may also suggest it by showing signs of an opening in the baby’s spine. After birth, doctors can usually recognize it by seeing the opening or fluid-filled sac on the back and checking movement, feeling, and bladder and bowel function, then use scans such as ultrasound or MRI to see how much the spine and nearby nerves are affected. Genetic testing is not usually what makes the diagnosis, but it may be offered if the care team is also looking for another genetic condition.
Stages of Open spinal dysraphism with a myelomeningocele
Open spinal dysraphism with a myelomeningocele does not have defined progression stages. This is because it is a birth condition that is present from the start, rather than an illness that typically moves step by step through mild, moderate, and severe phases over time. Doctors usually identify it during pregnancy on ultrasound, at birth by seeing the opening in the spine, and with imaging such as MRI to understand how the spinal cord and nearby tissues are affected. Ongoing follow-up focuses on related problems that can change over time, such as movement, bladder or bowel control, hydrocephalus, and the early symptoms of tethered cord, so care is based on a person’s needs rather than a stage.
Outlook and prognosis
Outlook for people with open spinal dysraphism with a myelomeningocele varies widely and depends on the level of the spinal lesion, the severity of hydrocephalus or Chiari II malformation, associated orthopedic or urologic problems, and how early complications are treated. With modern neurosurgical closure, shunting or endoscopic treatment when needed, infection prevention, bladder and bowel management, and rehabilitation, many affected children now survive into adulthood and can attend school, work, and participate in community life. Long-term challenges commonly include paralysis or weakness of the legs, impaired bladder and bowel control, recurrent urinary tract problems, skin breakdown, scoliosis, and the need for repeated surgeries, all of which can affect independence and quality of life. Cognitive outcomes are often better when hydrocephalus is well controlled, although some individuals have learning, attention, or executive-function difficulties. Mortality is highest in infancy and early childhood when severe brain malformations, untreated hydrocephalus, prematurity, or infection are present, but overall survival has improved substantially in specialized multidisciplinary care. In adulthood, reduced life expectancy is most often linked to complications such as renal disease, sepsis, respiratory problems, and shunt-related issues rather than the spinal defect alone.
Long-term effects
Open spinal dysraphism with a myelomeningocele can affect movement, bladder and bowel control, learning, and day-to-day independence over many years. The long-term picture is often shaped by where the spinal opening occurred and whether related problems, such as fluid buildup around the brain, are also present. Long-term effects vary widely, and many living with open spinal dysraphism with a myelomeningocele have a different mix of physical, cognitive, and medical needs as they grow older. Some features are present from early life, while others become more noticeable during childhood, the teen years, or adulthood.
Weakness or paralysis in the legs can make standing, walking, balance, and transfers harder over time. Many people with open spinal dysraphism with a myelomeningocele also develop tight joints, curved feet, hip problems, or scoliosis, which can further affect mobility.
Nerve changes often lead to long-term trouble with bladder control and bowel control. Over years, this can mean leakage, constipation, repeated urine infections, and strain on the kidneys if the bladder does not empty well.
Some children and adults with myelomeningocele have hydrocephalus, which can affect learning, attention, planning, and processing speed. In everyday life, this may show up as trouble keeping up with multi-step tasks, organizing schoolwork, or managing new routines.
Reduced feeling below the level of the spinal lesion can make pressure sores, burns, or shoe-related injuries easier to miss. Small skin problems can become serious if they are not noticed early, especially in people who spend long periods sitting.
How is it to live with Open spinal dysraphism with a myelomeningocele?
Living with open spinal dysraphism with a myelomeningocele can affect movement, bladder and bowel control, skin care, and sometimes learning or attention, so daily life often includes routines around mobility aids, catheterization, therapy, and regular medical visits. The impact varies widely: some people walk with braces or other support, while many use a wheelchair and plan carefully for pressure relief, accessibility, and fatigue. For families and other close supporters, this can mean helping with hands-on care, transportation, school or work accommodations, and watching for problems such as shunt issues, infections, or skin breakdown, but with the right equipment, medical care, and social support, many people build active, independent, and meaningful lives.
Treatment and drugs
Open spinal dysraphism with a myelomeningocele is usually treated in stages, starting with surgery soon after birth to close the opening in the spine and help lower the risk of infection and further nerve damage. Ongoing care often focuses on the effects of the condition, since treatment cannot reverse spinal cord injury that has already happened, and many living with open spinal dysraphism with a myelomeningocele may need help with movement, bladder and bowel control, skin care, and pain. Treatment plans often combine several approaches. These can include physical therapy, braces or other mobility aids, bladder medicines or catheter use, bowel programs, and treatment for related problems such as fluid buildup in the brain, also called hydrocephalus. Because needs can change over time, regular follow-up with a team that may include neurosurgery, rehabilitation, urology, and orthopedics is an important part of long-term care.
Can you cure Open spinal dysraphism with a myelomeningocele?
No. Open spinal dysraphism with a myelomeningocele, a birth condition where part of the spine and spinal cord do not close fully before birth, cannot be cured. Surgery before or after birth can close the opening and help lower some complications, and ongoing care can help with movement, bladder and bowel control, and other day-to-day challenges, but it cannot reverse nerve damage that has already happened.
Non-drug treatment
Care for open spinal dysraphism with a myelomeningocele usually focuses on protecting the spinal cord, supporting movement, and helping with bladder, bowel, skin, and learning needs as a child grows. Managing this condition often involves a team that may include neurosurgery, rehabilitation, urology, orthopedics, physical and occupational therapy, and school support. Needs can vary a lot from one person to another, depending on where the spinal opening is and whether problems such as hydrocephalus or a tethered cord are present. Early treatment and regular follow-up can make day-to-day life safer and more independent.
Most babies need surgery soon after birth to close the opening in the back and lower the risk of infection and further nerve damage. In some pregnancies, fetal surgery may be offered at specialized centers before birth, but it is not right for everyone.
Many living with open spinal dysraphism with a myelomeningocele also need treatment for extra fluid around the brain, called hydrocephalus. This may involve a shunt or another procedure to help fluid drain and to protect brain development and vision.
Physical therapy helps build strength, balance, and safe movement from infancy onward. Some children learn to sit, stand, transfer, or walk with support, while others focus on wheelchair skills and preventing joint stiffness.
Occupational therapy supports everyday skills such as dressing, bathing, feeding, handwriting, and using adaptive equipment. For many, treatment begins not at the pharmacy, but with small changes that make home and school tasks easier.
Your genes may have an impact on how drugs work for you
People living with open spinal dysraphism with a myelomeningocele often take medicines for pain, muscle tightness, bladder problems, or infections, and small inherited differences can sometimes change how fast the body breaks down certain drugs or how strongly side effects are felt. For example, one person may get too little relief from a usual dose, while another may become unusually sleepy, nauseated, or bothered by side effects even at a low dose. Even so, gene-based drug testing, sometimes called pharmacogenomics, is not a routine part of care for this condition, and treatment is usually tailored by watching how each medicine works in real life and adjusting it carefully.
Pharmacological treatments
There is no medicine that can close open spinal dysraphism with a myelomeningocele, so drug treatment usually focuses on related problems such as bladder control, bowel symptoms, pain, spasticity, and infection risk around surgery. Many living with open spinal dysraphism with a myelomeningocele take medicines as part of day-to-day care, especially if nerve changes affect the bladder or legs. Not everyone responds to the same medication in the same way. The best treatment plan depends on age, symptoms, and complications such as hydrocephalus, bladder dysfunction, or the early symptoms of tethered cord syndrome.
Oxybutynin, tolterodine, solifenacin, and mirabegron may help relax an overactive bladder and lower pressure on the kidneys. These drugs are often used in people with open spinal dysraphism with a myelomeningocele when nerve-related bladder problems cause leaking, urgency, or poor emptying.
Polyethylene glycol, lactulose, senna, and bisacodyl are commonly used to treat constipation and support a regular bowel routine. For many, this can mean fewer accidents, less belly pain, and less straining.
Drugs such as cefazolin are often given around the time of surgical repair to help prevent wound infection, and other antibiotics may be used if a urinary tract infection develops. The exact choice depends on age, the type of infection, and local treatment guidelines.
Acetaminophen and ibuprofen are often used for everyday pain or discomfort, while stronger medicines such as morphine may be used for a short time after surgery. Sometimes medicines are taken short-term for acute treatment, while others are used long-term if pain keeps coming back.
Genetic influences
When a baby is born with open spinal dysraphism with a myelomeningocele, many families want to understand the genetic causes of open spinal dysraphism with a myelomeningocele and whether it could happen again. It’s natural to ask whether family history plays a role. In most cases, open spinal dysraphism with a myelomeningocele is not caused by one single inherited gene; instead, the risk seems to come from a mix of small genetic differences that affect early spinal development and how the body handles folate, together with non-genetic factors. These other factors can include not getting enough folic acid before and during early pregnancy, certain anti-seizure medicines such as valproate, diabetes, obesity, and high body temperature early in pregnancy. Most families have no previous child with the condition, but having one affected pregnancy does raise the chance of it happening again compared with the general population. Because of that, genetic counseling and taking folic acid before conception can be especially helpful for families who have been affected by open spinal dysraphism with a myelomeningocele.
Is Open spinal dysraphism with a myelomeningocele genetic?
Genetics can play a part in open spinal dysraphism with a myelomeningocele, but it is usually not caused by a single gene change. Many small genetic variations, together with factors like low folate before and early in pregnancy, may raise risk.
Having a genetic risk is not necessarily a diagnosis
Genetic variants are a usual part of human biology and are common across the general population. Most do not have a direct effect on health and simply reflect natural human diversity. For many genes, having a variant connected with a condition points to a possible association rather than a definite diagnosis, especially when several genes and environmental factors are involved. In some cases, though, a single well-understood variant in a specific gene is enough to confirm a diagnosis.
Pharmacogenetics—how genetics influence drug effects
For many families, treatment for open spinal dysraphism with a myelomeningocele is shaped more by the child’s symptoms and complications than by a single gene result. Most care focuses on surgery, physical support, and medicines for related problems such as bladder spasms, constipation, pain, or infections, and there is no routine genetic test that reliably tells doctors which of these medicines will work best. Genetics is only one factor, and age, kidney function, other health conditions, and the level of the spinal opening often matter more when choosing doses and monitoring side effects. In some cases, open spinal dysraphism with a myelomeningocele happens as part of a broader genetic condition, which can change the overall treatment plan and how closely doctors watch for other organ problems. Researchers are also studying gene changes linked to folate use in the body, but today the clearest genetics-related step is prevention: folic acid before and during early pregnancy lowers the chance of neural tube defects in a future pregnancy rather than changing treatment after birth.
Interactions with other conditions
People living with open spinal dysraphism with a myelomeningocele often have health issues that affect the brain, bladder, bowels, bones, and skin as well as the spine. A common example is hydrocephalus, where extra fluid builds up around the brain, and many also have changes at the base of the brain and upper spine that can affect swallowing, breathing, or arm strength. Doctors call it a “comorbidity” when two conditions occur together. Open spinal dysraphism with a myelomeningocele can also be linked with a neurogenic bladder, which raises the risk of repeated urinary tract infections and, over time, kidney damage if bladder function is not well managed. Many living with open spinal dysraphism with a myelomeningocele also develop bowel control problems, pressure sores from reduced feeling, and bone or joint changes such as scoliosis or hip and foot problems, which can make mobility harder. Because these conditions can overlap, regular follow-up with neurosurgery, urology, rehabilitation, and primary care is important to catch problems early and protect long-term health.
How genes can cause diseases
Humans have more than 20,000 genes, each carrying out one or a few specific functions in the body. One gene instructs the body to digest lactose from milk, another tells the body how to build strong bones and another prevents the body's cells from beginning to multiply uncontrollably and developing into cancer. As all of these genes combined are the building instructions for our body, a defect in one of these genes can have severe health consequences.
Through decades of genetic research, we know the genetic code of any healthy/functional human gene. We have also identified that in certain positions on a gene, some individuals may have a different genetic letter from the one you have. We call these hotspots "Genetic Variations" or "Variants" in short. In many cases, studies have been able to show that having the genetic letter "G" in the position makes you healthy, but having the letter "A" in the same position disrupts the gene function and causes a disease. Genopedia allows you to view these variants in genes and summarizes all that we know from scientific research, which genetic letters (Genotype) have good or bad consequences on your health or on your traits.
What other conditions can cause similar symptoms to Open spinal dysraphism with a myelomeningocele?
Other conditions that can look similar to open spinal dysraphism with a myelomeningocele include other birth differences of the spine, especially a fluid-filled sac on the back without the spinal cord inside it, skin-covered forms of spina bifida, and a spinal cord that is abnormally tethered, or stuck, lower down. In babies, a lower-back lump can also be caused by a fatty lump or a growth near the tailbone, while leg weakness, foot changes, or bladder and bowel problems can overlap with other nerve or muscle conditions. Doctors usually tell these apart with a careful exam and scans of the spine.
History
For families, the history of open spinal dysraphism with a myelomeningocele is really a history of trying to explain why some babies were born with weakness in the legs, bowel or bladder problems, or a visible sac on the lower back. Long before modern scans or surgery, these differences were described in early medical writings, although doctors did not yet understand what caused them. Many living with open spinal dysraphism with a myelomeningocele today are benefiting from knowledge built slowly over centuries.
In recent decades, awareness has grown, but older records show that people had noticed this pattern for a very long time. Early descriptions focused on what could be seen at birth, especially an opening in the spine and problems with movement or sensation. As medicine advanced in the 1800s and 1900s, doctors began to separate open spinal dysraphism with a myelomeningocele from other spinal differences and to recognize that the condition could affect the brain, nerves, bladder, and bowel as well as the back itself.
A major turning point came with safer surgery, better newborn care, and imaging tests that let doctors see the spine and brain more clearly. This changed everyday life in very practical ways: instead of only describing the condition, doctors could close the opening soon after birth, treat fluid buildup around the brain when needed, and help children live longer and more active lives. Over time, researchers also identified that open spinal dysraphism with a myelomeningocele has a genetic component, while also recognizing that pregnancy-related factors can play a role.
Another important chapter was prevention. By the late 20th century, strong evidence showed that enough folate before and during early pregnancy could lower the chance of neural tube defects, including many cases of myelomeningocele. That discovery shaped public health advice in the US, Europe, and many other places, including folic acid supplements and food fortification in some countries.
Today, the history of open spinal dysraphism with a myelomeningocele is no longer just about survival. It is also about earlier diagnosis, improved surgery, rehabilitation, mobility support, and better treatment for bladder and bowel symptoms. For many families, this means care can start early and continue through childhood and adulthood, with a clearer understanding of the condition than ever before.
