Does your little one's head seem a little big? Or do you feel like you're too late to do things for their age? Sometimes it's normal to feel a little scared when you see things like this. Today we're going to talk about a condition that can be a bit of a headache for parents, but can be managed if you're aware of it. That's Dandy-Walker Syndrome . Don't worry, we'll talk about it in detail and simply.
What is Dandy-Walker Syndrome?
Simply put, Dandy-Walker Syndrome is a condition that occurs when a baby is born with a change in the way their brain develops . This is sometimes called Dandy-Walker Malformation. This happens while the baby is still in the womb, when the brain is developing. This means that it is a congenital condition.
This mainly affects the cerebellum, the little brain located at the back of our brain, in the brainstem , and the space around it. Did you know that this part called the cerebellum is the most important part of our Central Nervous System . It is the one that coordinates our body movements. Not only that, but it also helps with many other things. Take a look:
- It controls our body's balance , coordination, and posture .
- It also helps with vision- related matters.
- Our ability to think (cognition) is also related to things like understanding and remembering something.
- Motor skills are things like manipulating the limbs.
- It also contributes to behavior control.
This is called Dandy-Walker in honor of the two neurosurgeons , Walter Dandy, MD, and Arthur Walker, MD, who described the condition in the 1900s.
What happens to the brain of someone with Dandy-Walker?
Okay, so what happens to the brain of someone with Dandy-Walker? Here are some things that can happen:
- The fourth ventricle of the brain becomes larger. This is the space around the cerebellum. This is what helps cerebrospinal fluid (CSF) flow between the upper and lower parts of the brain and the spinal cord .
- The two hemispheres of the cerebellum, that is, the middle part that connects the two sides, is called the cerebellar vermis , and it can be completely or partially missing.
- A cyst , which looks like a water bubble, forms near the fourth ventricle.
- The base of the skull, that is, the posterior fossa, becomes larger.
- Sometimes, cerebrospinal fluid (CSF) can build up, increasing pressure inside the skull and causing it to swell. This is what we call hydrocephalus .
How common is Dandy-Walker Syndrome?
According to data from the United States, Dandy-Walker Malformation affects about one in 25,000 to 35,000 babies . It is more common in girls than boys.
What causes Dandy-Walker Syndrome?
This condition occurs when there is a problem with the baby's cerebellum developing in the womb . In some cases, this condition can be caused by a genetic mutation .
Some people with Dandy-Walker may have chromosomal conditions . This means that parts of the chromosomes are either missing or extra. You know, chromosomes are like the packages that carry our genes. Dandy-Walker Syndrome may also be part of a genetic disorder that occurs along with several other birth defects.
There are several other possible reasons:
- Some types of viruses can be passed from mother to baby during pregnancy.
- Exposure to certain toxins or medications during pregnancy.
- My mother has diabetes .
When do Dandy-Walker symptoms begin?
Sometimes, symptoms appear suddenly and clearly . Other times, parents may have symptoms without realizing anything is wrong.
Most often, symptoms appear within the first few months of a baby's life , but some children may not be diagnosed until they are 3 or 4 years old .
What are the symptoms of Dandy-Walker Syndrome?
Symptoms that can be seen in infants are:
- Developmental delays are delays in meeting age-appropriate developmental milestones . For example, delays in sitting up, crawling, and walking.
- The skull is larger than normal.
- Hypotonia , which means the body is just limp.
- Spasticity means that the muscles in the body become stiff and difficult to bend.
Symptoms seen in older children:
- Vomiting, seizures, and irritability – these are symptoms of increased pressure inside the brain.
- Loss of coordination, a wobbly gait, and unusual movements such as eye twitching – these are signs of problems with the cerebellum.
There may be some other symptoms:
- A swelling or lump at the back of the skull.
- Problems with the nerves that control the neck, face, and eyes.
- Abnormalities in breathing patterns .
- Seizures .
- Intellectual Disabilities .
- Symptoms of Hydrocephalus .
What is the difference between Dandy-Walker Complex and Dandy-Walker Syndrome?
This may sound a bit complicated, but I'll keep it simple. Dandy-Walker Complex is a group of conditions that have similar symptoms. Dandy-Walker Syndrome is just one of those conditions.
There are other conditions that belong to the Dandy-Walker Complex:
- Isolated Cerebellar Vermis Hypoplasia or Dandy-Walker Variant : In this condition, the cerebellar vermis is small or not fully developed. However, the other structural changes in the brain of children with Dandy-Walker Syndrome are not seen. Most children diagnosed with this condition develop normally.
- Mega Cisterna Magna : In this condition, the posterior fossa at the back of the skull is enlarged, but the cerebellum is normal. Mega Cisterna Magna usually does not cause any health problems.
- Posterior Fossa Arachnoid Cyst : This is a cyst that develops in the posterior fossa. It is very rare for children to have symptoms even if they have this type of cyst.
What other conditions are associated with Dandy-Walker Syndrome?
Children with Dandy-Walker may also have problems with other parts of the central nervous system. For example:
- Absence of the Corpus Callosum (ACC) is a rare, congenital condition.
- Problems with the way things like limbs, face, heart, fingers are formed.
Will my child have an intellectual disability?
Less than half of children with Dandy-Walker have intellectual disability . Intellectual disability is most common among children with Dandy-Walker who have the following conditions:
- Severe hydrocephalus .
- Chromosomal Conditions .
- Other congenital conditions .
Remember, every child is different, so one child's experience will not be the same as another's.
How is Dandy-Walker Syndrome diagnosed?
Sometimes doctors or parents may notice that a child's head is too large . Or they may notice that the child is not meeting developmental milestones . Doctors may order brain imaging tests to diagnose Dandy-Walker. These tests may include:
- Ultrasound examination.
- CT scan.
- MRI scan.
Occasionally, this condition can be detected during a prenatal ultrasound or fetal MRI scan before the baby is born.
If my child has Dandy-Walker, does the family need to undergo genetic testing?
If your child has Dandy-Walker Malformation, it is important to talk to your doctor about genetic counseling . A small percentage of people with this condition may also have a family member with the condition. Because there may be a genetic component to it, many doctors recommend genetic testing .
What are the treatments for Dandy-Walker Syndrome?
Treatment depends on the symptoms of Dandy-Walker Syndrome. It is important to get a thorough examination by a doctor before starting treatment. For example, doctors may recommend the following:
- Ventriculoperitoneal (VP) Shunt : Surgeons insert a small device called a VP shunt to remove excess fluid from the brain. This shunt can reduce pressure on the brain and improve symptoms.
- Medications : Your child's doctor may prescribe medication to control seizures.
- Therapy : Physical therapy and occupational therapy help children maintain muscle strength. Therapists can also teach children new ways to do everyday tasks. Speech therapy helps with language and speech development.
- Special Education : A tailored learning environment helps children achieve their educational and social goals.
What is the future of children with Dandy-Walker Syndrome?
Your child's future and lifespan will depend on how severe their condition is , as well as any other congenital conditions they may have.
People with this condition can have a variety of experiences. Some have mild symptoms . Others have profound disabilities . Some children can achieve normal cognitive abilities with a proper treatment plan. For others, even if their medical team diagnoses and treats the condition quickly, they may not be able to reach that level.
Can Dandy-Walker Syndrome be prevented?
There is no known way to prevent Dandy-Walker Syndrome. However, consistent prenatal care gives you the best chance of having a healthy pregnancy. Follow your doctor's advice to stay healthy while you are pregnant.
How do I care for my child with a Dandy-Walker?
Early intervention can give your child the best chance for successful treatment. If you notice that your child is not meeting developmental milestones like sitting, walking, or talking on time, see your doctor. They can then make an accurate diagnosis and provide the most effective treatment plan for your child.
Your child's Dandy-Walker care team may include:
- Pediatrician .
- Development Specialists .
- Speech, Occupational and Physical Therapists .
- Special Education Professionals .
What should I ask my doctor about Dandy-Walker Syndrome?
If your child is diagnosed with Dandy-Walker, ask your doctor about the following:
- Will my child need a shunt ?
- What other medical conditions does my child have?
- What will my child's future (outlook) be like?
- How can we improve my child's symptoms ?
- Should we do genetic testing ?
Finally, remember this.
Dandy-Walker Syndrome, also known as Dandy-Walker Malformation, is a brain condition that develops before a baby is born. Babies with Dandy-Walker often reach developmental milestones late. Some children need a shunt to remove excess fluid from the brain. Treatments can help children manage daily activities, succeed in school, and live fulfilling lives. If you notice that your child's head is too large or that they are not sitting, walking, or talking as expected, talk to your doctor. Early recognition and proper treatment are important. Don't worry, this condition can be managed with medical advice.
