Your child used to run around and play and talk beautifully. But has his speech suddenly decreased? Or have you noticed that he has difficulty understanding what you are saying? Does he sometimes have seizures? If your child has one or more of these things, you need to do some research. Because this may be due to a rare condition called Landau-Kleffner Syndrome (LKS) . Don't worry, let's talk about this in detail.
What is Landau-Kleffner Syndrome?
Simply put, Landau-Kleffner Syndrome (LKS) is a condition that affects our children's brains. The main thing in this is that the child's ability to speak and understand language (which we call in medical science (Aphasia) ) gradually or suddenly decreases. Also, most of the children with this condition can suffer from seizures, which occur during sleep.
Think about it, there are lots of little electrical messages going back and forth inside our brains. These electrical signals are what help us function properly when we speak, hear, think, and do everything. Children with LKS have some abnormality in this electrical signal system in their brains. This is why they have difficulty understanding language and speaking.
Who is most affected by this LKS situation?
This condition, called LKS, is usually seen in children between the ages of 3 and 8. However, it can sometimes affect children as young as 2 years old, as well as older children, such as teenagers. It is also said that boys are slightly more likely to develop this condition than girls.
How does LKS affect my child?
If your child has LKS, they may suddenly or gradually lose the ability to speak. They may also have difficulty understanding what you say and what others say. This is what we call (aphasia) .
Imagine, your child used to recite poems, sing songs, and talk to you nonstop. But now he doesn't say a single word, or he just stares at you when you speak, as if he doesn't understand anything, how hard it is to be honest?
About 70% of children with LKS may experience epileptic seizures, or convulsions, during sleep. Some children may also have these seizures during the day.
Is Landau-Kleffner syndrome the same as autism?
No, this is a common misconception. Landau-Kleffner Syndrome is not autism. However, the symptoms of both can sometimes be similar, so it can be difficult to tell the difference. Doctors usually diagnose the two conditions by performing EEG tests (electroencephalograms) while the child is awake and asleep.
Are there other names for LKS?
Yes, sometimes doctors also call this condition "Acquired Aphasia with Epilepsy." That is, it means something like "speech impairment that occurs with epilepsy and is acquired later."
How common is this LKS condition?
Landau-Kleffner Syndrome is a very rare condition. It's hard for researchers to say exactly how many people actually have it. It's that rare.
What causes Landau-Kleffner syndrome?
In most cases, the majority of children with LKS cannot find a specific cause for their condition. This is the truth. So don't overthink it or blame yourself.
However, about 20% of children with LKS have certain changes (mutations) in their genes. In particular, changes in a gene called (GRIN2A) have been found to be related to this. These genetic changes can be inherited from one of the parents. However, not everyone with this genetic change will develop LKS. Some children may also have changes in other genes. Sometimes, the child may develop this gene mutation for the first time (this is called a de novo mutation ) without anyone else in the family.
Researchers believe that these genetic changes cause a malfunction in the brain's electrical signaling system, causing those signals to function incorrectly. These abnormal signals are what cause the symptoms of LKS.
Research is also being conducted to determine whether there is a link between LKS and our body's immune system . It is believed that this condition may be caused by an autoimmune response in which the immune system's own cells attack the body's own cells.
What are the symptoms of Landau-Kleffner syndrome?
Not all children with LKS show the same symptoms. It can vary from child to child.
If your child has LKS, you may notice things like:
- Feeling like he can't hear you when you talk: He may not respond when you talk to him. It's as if he didn't hear you.
- Difficulty understanding what you and others say: You may not be able to understand even simple instructions.
- Decreased or complete loss of speech: A child who previously spoke well may no longer speak at all, or may only be able to speak a few words with great difficulty.
- New developmental delays: Inability to do things in a way that is age-appropriate.
- Intellectual changes or learning difficulties: You may lose interest in schoolwork and have difficulty remembering things.
- Behavioral changes: These language difficulties can cause frustration in the child, which can lead to behavioral problems such as restlessness, inability to pay attention (this may be similar to symptoms of Attention-Deficit Hyperactivity Disorder - ADHD), tantrums, and fidgeting .
Imagine how helpless a little child feels when he can't tell his parents what he wants to say, when he doesn't understand what they're saying? That helplessness and frustration is what sometimes comes out in this kind of behavior.
Children with LKS mainly:
- You may not be able to speak.
- There is a higher chance of seizures.
- There is also a higher chance of developing behavioral disorders (such as Attention-Deficit Hyperactivity Disorder - ADHD) .
How do doctors diagnose Landau-Kleffner syndrome?
Usually, before LKS begins, a child's development, such as talking and walking, is normal for their age. You may notice a change in their speech right away. Or, your doctor may notice these symptoms when you take your child for a well-child visit.
LKS can be a bit challenging to diagnose, so it's important to tell your doctor about any changes you notice in your child's behavior, even the smallest ones.
What tests do doctors use to diagnose LKS?
Your child's doctor may recommend these tests:
- Electroencephalogram (EEG): This measures the electrical activity of your child's brain. This is a painless test. It allows the doctor to see how your child's brain is functioning.
- This (EEG) test is usually done twice, once when the child is asleep and once when they are awake . When we go to sleep, our brain waves gradually slow down. However, when we enter a deep sleep (REM sleep phase), the brain waves become active again. However, the (EEG) records of children with LKS show that abnormal brain wave activity continues throughout all stages of sleep.
- Audiometry / Hearing test: This test is done to see if the child can hear. Sometimes, it is also necessary to check if a hearing impairment is the cause of language problems.
- MRI of their brain: This helps to make sure there is no other serious condition, such as a brain tumor.
- Evaluation by a psychologist: This is important to get an assessment of the child's behavior, intelligence, and learning abilities.
How is Landau-Kleffner syndrome treated?
When treating children with LKS, doctors mainly use medication, speech therapy, and behavioral therapy . The sooner speech therapy begins, the better the child's chances of regaining his or her language skills. Sometimes, doctors may also recommend a special diet (ketogenic diet) to control epilepsy.
What medications are given for LKS?
Your doctor may prescribe medications such as:
- Anticonvulsant medications: These are used to control seizures.
- Corticosteroids: These work by reducing the activity of the immune system and controlling conditions such as brain swelling.
Is surgery performed for LKS?
Very rarely, doctors can perform a brain surgery called Multiple Subpial Transections . However, it is not yet clear how much benefit can be proven from this surgery. Therefore, it is important to carefully examine the pros and cons of the surgery before undergoing it.
How soon will my child recover after starting treatment?
There is no one "this is the best way" to treat LKS. Your child may gradually improve with speech therapy and other treatments. However, in some cases, your child may not respond well to treatment. Your doctor will monitor your child's condition regularly and adjust the treatment plan as needed.
What can I do to reduce the risk of my child developing Landau-Kleffner syndrome?
LKS is a genetic condition. This means that there is really nothing you can do to prevent Landau-Kleffner Syndrome or reduce your risk of developing it. It is not your fault.
Can Landau-Kleffner syndrome be completely cured?
Some children regain their ability to speak and understand language. Others may regain some language skills. Children who begin symptoms after age 6 and who start speech therapy early have the best chance of recovery. Seizures often stop by adulthood.
What should I expect if my child has LKS?
It can take a long time for your child to recover from LKS. You may see some improvements over time. Also, sometimes language skills may improve and then decline again (this is called a relapse) . Your doctor may recommend special education classes or sign language learning, depending on your child's needs.
This journey is difficult. But you are not alone. Doctors, speech therapists, your family, and friends are all there to help you and your child. The most important thing is to treat your child with love and patience, without giving up hope.
How do I take care of my child with LKS?
Follow your doctor's instructions carefully to keep your child healthy. If your child develops any new symptoms, let your doctor know right away. This way, they can get the necessary treatment right away.
Landau-Kleffner Syndrome causes children who have normally developed to lose their ability to speak and understand language. Children with LKS have abnormal brain activity during sleep and often have seizures. Doctors treat LKS with medication and speech therapy. Over time and with proper treatment, children can regain their language skills.
Important things to remember (Take-Home Message)
- LKS is a rare but serious condition: it can cause a child to lose their ability to speak and understand language.
- Seizures are common during sleep: This is a key feature of LKS.
- The cause is not always found: Although genetic factors may play a role in many cases, there may also be no specific cause.
- Don't confuse it with autism: The two can be distinguished through (EEG) tests.
- Early diagnosis and treatment are crucial: the sooner speech therapy begins, the better the results.
- Recovery varies from child to child: some children recover completely, others recover partially. Patience and continued support are very important.
- You are not alone: Medical advice, family support, and love are great strengths for a child to overcome this situation.
I hope this information is helpful to you. If your child has any of these symptoms, please see a qualified doctor as soon as possible.
