Is your baby's white matter damaged? Let's talk about Periventricular Leukomalacia (PVL)

If your baby was born prematurely, or if you are experiencing any developmental delays, this is very important for you. Sometimes, small areas of the brain in babies can be damaged. This is a condition called periventricular leukomalacia, or PVL for short. Don't be alarmed by this, let's talk about it in detail.

What is PVL? Let's understand it simply.

Okay, let's see what PVL (Periventricular Leukomalacia) is simply. You know, our brain is a very complex, amazing organ. It has different parts. One important part is the 'white matter' . This is like the 'wire' system in our brain. Brain cells, that is, nerve cells (neurons) , communicate with each other and from the brain to the spinal cord, and exchange information through this 'wire' system, that is, the (white matter) .

So, if your baby has periventricular leukomalacia, it means that there is damage to a part of this white matter . This damage can cause developmental delays in the baby's motor skills, which is how they control their body, as well as their intellectual skills, which is how they think and understand things. Not only that, but babies with this condition are also at increased risk of developing a condition called cerebral palsy .

Let's break down this long name 'periventricular leukomalacia' a bit and understand it. Then it will be clearer:

• 'Peri' means 'around' or 'surrounding'.
• 'Ventricular' refers to the fluid-filled cavities inside the brain. We also call these ventricles .
• 'Leuko' means 'white'. This refers to the white matter of the brain.
• Malacia is an abnormal 'softening' of tissues that occurs when tissue is damaged. Doctors can see this through tests.

So, simply put, periventricular leukomalacia is damage to the white matter around the ventricles in your baby's brain, causing them to soften.

Babies born before 32 weeks of gestation, or very preterm, are at the highest risk of developing PVL. This risk increases with the shorter the gestational age at which they are born, or how early they are born.

If your baby was born prematurely, I understand that you have a thousand questions and fears in your mind. You probably have many thoughts about your baby's health and future. But remember, your baby's medical team is always there to help you understand this situation, and to help and guide you and your family.

What are the symptoms of a baby with PVL?

It's usually hard to tell right away if a baby has PVL just by looking at them. That means there may be no obvious outward signs . But over time, PVL can cause one or more of the following symptoms. It's important to keep an eye out for these:

• Motor delays: Difficulty sitting up, crawling, walking, or using limbs properly. For example, some babies may be slower to hold their necks up properly, or may be slower to roll over or sit up than other babies.
• Cognitive delays / (Intellectual disability): A lack of understanding and learning abilities. This may include things like a delay in speaking words or difficulty understanding simple instructions.
• Balance problems: Difficulty maintaining balance.
• Vision and hearing impairments.
• Spastic quadriplegia (stiffness in all four limbs, more precisely, difficulty in bending or extending) or diplegia ( stiffness in only two legs) – these can also be symptoms of cerebral palsy .

These symptoms usually become apparent by the age of 2. One thing to remember is that PVL varies from baby to baby. It does not affect everyone in the same way.

What are the causes of PVL?

The main cause of PVL is when the baby's brain doesn't get enough blood or oxygen , either before or after birth. Think about it, our brain cells need oxygen and nutrients to live and function. When these are not properly supplied, those cells are damaged.

As mentioned earlier, babies who are born prematurely (preterm) , or those who are born small for gestational age (small for gestational age), are at the highest risk. This is because their brains are still developing, making them very delicate. Therefore, they are more susceptible to damage.

Some other things that may be associated with PVL include:

• Bleeding into the brain (Intraventricular hemorrhage) .
• Premature rupture of the amniotic sac during pregnancy.
• Infection of the mother's uterus during pregnancy.

How do doctors diagnose PVL?

If your baby is born prematurely, your doctor may recommend some special screening tests in the first few days and weeks of your baby's life. These are done to detect any brain damage early. Sometimes, the tests may not be done until your baby shows signs of the condition, such as developmental delays.

There are several tests that can accurately diagnose PVL:

• Brain MRI scan: An MRI (Magnetic Resonance Imaging) scan can take very clear, detailed pictures of your baby's brain. This can look for patterns of damage to the white matter of the brain, which is consistent with PVL.
• Head ultrasound: An ultrasound uses sound waves to create pictures of body tissues. This is also a method used to diagnose PVL. If your baby has PVL, the ultrasound can show changes in the white matter of the brain.

What are the treatments for PVL?

There is currently no direct treatment or cure for PVL. The damage to the brain caused by PVL is permanent . But don't worry. There are a variety of therapies that can help control your baby's symptoms and improve their quality of life . These can provide a lot of relief for your baby. These may include:

• Physical therapy: This helps your child improve their movement, or body control. This includes both fine motor skills (such as holding a pencil, buttoning a button, tying shoelaces) and gross motor skills (such as sitting, kneeling, walking, and running). Imagine how strong a child can be if they receive this type of therapy from an early age!
• Occupational therapy: This helps the child learn new ways to do everyday tasks, such as eating with utensils and getting dressed, on their own. This is very important to increase the child's independence .
• Speech therapy: If your child has difficulty speaking or communicating with others, this therapy can help. It can help with things like pronunciation, sentence formation, and comprehension.
• Assistive devices: Assistive devices such as wheelchairs, walkers, and crutches can help increase a child's mobility, or ability to move around. These can help a child do many things on their own.
• Medications: Some medications can help control symptoms such as muscle spasticity , or other medical conditions (such as epilepsy) that the child may have. These should only be used under the guidance of a doctor.
• Social services and educational support: Your child may need extra support with schoolwork or other aspects of daily life. Social workers, educational specialists, and other professionals can provide these types of support services and help.

The most important thing is that all of this is done to help the child live as good, comfortable, and happy a life as possible.

Can we prevent PVL?

There is really nothing you can do directly to prevent PVL. The main goal is to try to prevent preterm birth . This is because preterm birth is a major risk factor for PVL. If you are at risk of having a premature baby, going to a place that has specialized medical facilities for premature births can help prevent this condition to some extent.

Although preterm birth cannot always be prevented, you can reduce your risk by taking these steps during pregnancy:

• For regular prenatal care , that is, go to clinics and see doctors.
• Manage your health conditions, such as diabetes mellitus , high blood pressure, or depression .
• Completely avoid smoking, alcohol, or other drug use.
• Eat nutritious food .
• Gain weight in a healthy way during pregnancy.
• Protect yourself from infections that can harm you and your unborn baby.
• Try to reduce stress as much as possible and stay relaxed.

If my child has PVL, what can I expect for the future?

Not all children with PVL are affected in the same way. This means that one child can be very different from another . The prognosis/outlook for a child depends on several factors. For example, the severity of the brain damage and other health problems the child has.

Some children may have very mild symptoms , or no symptoms at all. They may live a normal life. However, others may have significant physical and/or intellectual disabilities . Your doctor will be able to give you some idea of ​​the nature of the damage your baby has suffered and how it may affect their development.

Just think, sometimes a child may seem like a big problem when they are young, but with the right treatment, they can get into a much better situation with their own interest. So, don't give up hope.

It is impossible to predict exactly how your baby will be affected. The best thing you can do is talk to specialists who research and treat PVL. As your child gets older, they will benefit greatly from the help of a team of specialists who can tailor their treatment to their needs.

What is the life expectancy of someone with PVL?

This is a concern for many parents. Most babies with PVL can be expected to live a full life . However, if your baby has severe brain damage or other serious medical conditions , their life expectancy may be slightly shorter. Some factors that can affect their life expectancy include:

• Difficulty eating and drinking.
• Inability to move the body or mobility problems.
• Respiratory difficulties.

These don't affect everyone, but it's good to be aware of things like this. Talk to your doctor about this.

So, let's look at some of the things we need to remember from this? (Take-Home Message)

A mother or father goes through so many emotions during and after the birth of a baby, right? Especially if the baby is born prematurely or has to be kept in a NICU (Neonatal Intensive Care Unit) , the burden that you feel at that time is hard to put into words. Then, as you spend days and weeks with doctors and tests, you may have to deal with more than you thought possible. You may feel like everything is out of control, and you may even blame yourself.

But, in this condition called periventricular leukomalacia (PVL) , there is no one to blame . Not even researchers know exactly what causes it. Another important thing is that PVL affects every child differently . So, it is important to work closely with your child's medical team to provide the best medical care, advice, and support as your child grows.

Remember, you are not alone on this journey. Your doctors, nurses, therapists, as well as your family and friends are all there to support you.

Also, it is very important to take care of yourself . Only when you are strong and healthy can you take good care of your child. Whenever you are feeling down, talk to someone you trust. If necessary, don't hesitate to seek counseling. The dedication you make to your child is priceless.
