What is Wernicke-Korsakoff Syndrome? Let's talk about it!

Have you ever heard of a strange condition that affects the brain and memory? Sometimes, we don't even realize that when our body lacks certain vitamins, especially vitamin B1 called ``Thiamine``, our brain can be seriously damaged. One such serious condition is ` `Wernicke-Korsakoff Syndrome`` (``WKS``) . This is a condition that really requires emergency treatment. Shall we talk about this simply, in a way that you can understand?

What exactly is Wernicke-Korsakoff syndrome (`WKS`)?

Simply put, this is a disease that affects our brain and memory. The main reason for this is that our body has a significant decrease in 'Thiamine' (`Thiamine`) or vitamin B1 . Think about it, our body is like a vehicle. The engine of this vehicle is the brain. The engine needs gasoline to run. Similarly, the vitamin called 'Thiamine` (`Thiamine`) is essential for our brain and nervous system to function. This vitamin is what converts the food we eat into energy. So when this 'Thiamine` (`Thiamine`) is reduced, the brain does not get the energy it needs, and then the brain cells start to get damaged.

There are two main stages in this `WKS`:

1. Wernicke encephalopathy: This is the first, sudden, severe brain injury. It requires immediate treatment.

2. Korsakoff syndrome: This is a long-term condition that severely affects memory.

It is named after the German neurologist Carl Wernicke and the Russian neurologist Sergei Korsakoff, who first identified the condition.

What is the relationship between 'Wernicke's encephalopathy' and 'Korsakoff syndrome'?

The two are related. To be precise, a condition called ``Wernicke encephalopathy``, if not treated in time, is what gradually develops into a severe memory problem called ``Korsakoff syndrome``.

There are usually three main symptoms of Wernicke encephalopathy:

• Confusion: Loss of consciousness, loss of place and time.
• Loss of balance and inability to control movements (`Ataxia`): Walking becomes unsteady and limbs become difficult to control.
• Vision changes and eye problems: Abnormal eye movements, such as seeing double.

In addition to this, sometimes even the muscles can become weak.

If these symptoms persist for a long time, permanent damage occurs to the brain and nerve cells. This is when severe memory loss occurs and new memories cannot be remembered. This is called ``Korsakoff syndrome``.

Wernicke-Korsakoff Syndrome (WKS) is a condition that can become progressively worse over time and can even be life-threatening. Therefore, urgent treatment with thiamine is essential. Doing so can help relieve symptoms and prevent permanent damage to memory and other brain functions.

If you or someone close to you has these symptoms, you should immediately see a doctor or go to the nearest hospital.

Who is most affected by this situation?

Wernicke-Korsakoff syndrome (WKS) is more common in men than women. It usually occurs in people between the ages of 30 and 70. Most people who develop WKS due to alcohol use are men over the age of 40. However, women and younger people can also develop the condition for reasons other than alcohol. It is rarely reported in young children.

Who is at higher risk of developing Wernicke-Korsakoff syndrome?

Wernicke encephalopathy is a condition most commonly seen in people who use alcohol excessively (alcohol use disorder). When alcohol is consumed for a long time, it damages the stomach and digestive system. It also interferes with the body's ability to absorb vitamins (malabsorption). It is said that about 80% of alcoholics cannot absorb or retain enough thiamine.

Additionally, people who cannot absorb food properly due to certain medical conditions can also develop `WKS`. For example, it can occur after weight loss surgery (`bariatric surgery`) or as a side effect of `chemotherapy` for cancer.

Here are some other risk factors:

• Intestinal diseases, for example, inflammatory bowel disease or gastropathy.
• Cancer (especially in severe cases).
• Excessively high thyroid hormone levels (thyrotoxicosis).
• Some genetic mutations.
• Use of diuretic therapy for heart failure for a long time.
• Thiamine deficiency diseases such as HIV/AIDS.
• Kidney failure, because long-term dialysis treatment reduces the body's ability to absorb thiamine.
• Lack of access to medical facilities or nutritious food.
• Excessive vomiting and nausea during pregnancy (hyperemesis gravidarum).

What are the causes of 'Wernicke-Korsakoff syndrome'?

The main reason for this is a deficiency of ``Thiamine``. This essential vitamin is what converts the sugar we eat into energy. So when we don't have enough ``Thiamine``, our brain doesn't get the energy it needs to function properly.

The main cause of thiamine deficiency is excessive alcohol consumption over a long period of time. Alcohol makes it difficult for the body to absorb thiamine and store it in the liver. Alcohol also interferes with the use of vitamin B1 for other essential functions.

There are other reasons too:

• Improper nutrition: Not eating a balanced diet.
• Eating disorders: such as anorexia and bulimia.
• Chronic infections.
• Surgeries: Especially surgeries like gastric bypass surgery for weight loss.
• Traumatic brain injury: But this is a bit rare.

What are the symptoms of 'Wernicke-Korsakoff syndrome'?

This can manifest in a variety of symptoms. One of the most common symptoms seen in severe cases is 'confabulation' . That is, making up stories in your mind to cover up things you don't remember. Imagine, someone doesn't remember something they did yesterday, but they tell a lie to cover it up, but they don't lie because they think it really happened. They believe the story.

People with this condition may often feel confused or disoriented. This confusion makes it difficult for them to realize that something is wrong with them and to seek treatment.

Common symptoms of Wernicke encephalopathy:

• Loss of balance or inability to control movements (ataxia).
• 'Confabulation'.
• Confusion, delirium.
• Difficulty walking, unsteady gait.
• Drowsiness.
• Abnormally low body temperature (hypothermia).
• Heart problems: increased heart rate (tachycardia) or low blood pressure (hypotension).
• Loss of muscle coordination (ataxia).

Eye problems are also common:

• Abnormal eye movements (nystagmus).
• Double vision.
• Drooping of the upper eyelid (ptosis).
• Eye muscle dysfunction or weakness (ophthalmoplegia).

If Wernicke encephalopathy is left untreated, it can progress to Korsakoff syndrome, a long-term memory disorder. Its symptoms include:

• Complete loss of memory (`Amnesia`) or inability to remember anything new.
• Behavioral changes: irritability, quick temper.
• 'Confabulation'.
• Delirium and disorientation.
• Fatigue or lethargy.
• Hallucinations, especially when withdrawing from alcohol.
• Inability to concentrate.
• Unsteady gait.

Some symptoms do not improve completely even with treatment. In severe cases, loss of consciousness (`coma`) can occur. If you or someone close to you loses consciousness, or if you have symptoms of `Wernicke-Korsakoff syndrome`, see a doctor or go to an emergency room immediately.

How is 'Wernicke-Korsakoff syndrome' diagnosed?

Early detection of this `WKS` condition is crucial for successful treatment. Doctors diagnose it by performing a physical exam, asking about your symptoms, and asking about your family history. However, it can be difficult to diagnose when someone is confused or has memory loss.

The doctor will specifically check for these things:

• Are there any alcohol use problems (`Alcohol use disorder`)?
• Is there malnutrition?
• Is there a thiamine deficiency?

What tests help diagnose Wernicke-Korsakoff syndrome?

Your doctor will order blood tests to check your blood sugar and thiamine levels. They may also order a blood alcohol test to check for alcohol use and a liver function test to check liver function, as this may indicate liver damage.

Further tests may be done to check for other causes:

• Arterial blood gas (ABG) test, which checks the levels of carbon dioxide and oxygen in the blood.
• 'Complete blood count' (`Complete blood count - CBC`).
• Toxicology screening.

You may also need to have imaging tests like these:

• 'CT scan'.
• 'MRI' (`MRI`).
• 'Electrocardiogram' (`Electrocardiogram - EKG`).

Can Wernicke-Korsakoff Syndrome be cured? How is it treated?

In fact, it is not completely curable. However, if treatment is started early, the symptoms can be relieved and some of them can be reversed. This means that the condition ``Wernicke encephalopathy`` can be stopped from worsening to ``Korsakoff syndrome``.

In most cases, treatment can control or improve symptoms such as confusion, eye problems, and loss of balance. Your doctor will develop a treatment plan that is right for you.

The following are usually done as treatment:

• Giving vitamin B1 through pills or injections.
• If the body is dehydrated, administer saline through ``IV fluids``.
• Treating problems related to alcohol use.
• Providing nutritional support.
• Administer other medications if necessary.

How can you reduce the risk of developing this condition?

In most cases, stopping or limiting alcohol consumption is the most important thing you can do to reduce your risk of developing Wernicke-Korsakoff syndrome. Also, getting good nutrition and, if necessary, taking thiamine supplements in the form of injections or pills can help reduce your risk, especially for those who are addicted to alcohol.

What is the prognosis for someone with Wernicke-Korsakoff syndrome?

If you or someone close to you has this condition, the prognosis depends on how severe the symptoms are and how quickly the disease is diagnosed and treated. Early treatment can reverse symptoms and prevent long-term complications. However, if left untreated, it can lead to disability and even death.

When should you seek medical advice for this condition?

If you or someone you know has symptoms of Wernicke-Korsakoff syndrome, seek medical attention immediately. You may need to call your doctor or go to the nearest hospital emergency room for emergency treatment.

How do I take care of myself?

Receiving a diagnosis of Wernicke-Korsakoff syndrome is not an easy task. You may need to be hospitalized and receive treatment. The most important thing is to follow your doctor's advice, such as limiting your alcohol consumption (or cutting it out completely) and eating a nutritious diet. These things will greatly support your recovery.

Follow your doctor's instructions carefully to manage complications and treat symptoms. He or she will create a personalized care plan that is right for you and help you get back to your health.

Wernicke-Korsakoff syndrome is a rare but serious memory disorder. It requires urgent treatment to relieve symptoms and prevent complications. As the disease progresses, symptoms of the nervous system, such as severe confusion and disorientation, occur. These symptoms can make it difficult for you or someone close to you to recognize your condition. Therefore, it is important to diagnose the disease early. Your doctor will recommend a treatment plan that is tailored to your needs.

The most important things to remember (Take-Home Message)
