Is there a problem inside your head? Let's learn exactly about encephalitis!

Have you ever heard of a dangerous disease that causes the brain to become infected and swell? Maybe one of your friends or family members has had it. This is what we call encephalitis in medicine. It is actually a bit serious, and it is not a common disease. However, it is very important to be aware of this, because if it is recognized early, it can be treated.

What is Encephalitis? Let's understand it simply!

Simply put, encephalitis is an inflammation that occurs inside our brain . It's like when we get an injury somewhere on our body, the area becomes red and swollen. But this happens to the brain, which is the control center of our body. This swelling can put pressure on the brain, which can interfere with how the brain works.

There are two main reasons why this condition occurs. One is that it is caused by an infection . The other is that it is caused by a problem with our own immune system , that is, an autoimmune process. Whatever the cause, (Encephalitis) is a serious condition that can be life-threatening and can cause long-term health problems and complications. That is why this condition often requires hospitalization, special treatment in intensive care units, and sometimes even life support measures.

What are the main types of encephalitis?

Let's see what the main types of Encephalitis are. There are two main types:

1. Encephalitis caused by an infection (Infectious Encephalitis):

• (Viral Encephalitis): This is the most common type. This condition can occur after various viral infections, such as influenza. Think about it, when some people get diseases like measles and mumps, it becomes severe and affects the brain, that's how it is.
• (Arbovirus Encephalitis): This is a bit special. The infections that cause this are transmitted by animals like mosquitoes, fleas, and ticks. In our country, there is no need to talk about diseases transmitted by mosquitoes. Like dengue, dangerous conditions like this can also occur.
• Bacterial or Fungal Encephalitis: Encephalitis caused by bacterial or fungal infections is very rare, but it can happen.

2. (Autoimmune Encephalitis):

This is a very strange thing that happens. The immune system, which is supposed to be the protector of our body, mistakenly attacks our own brain. It's like attacking our own family. This can cause swelling in the brain and affect brain function. Sometimes people with cancer can also experience this condition. Doctors call this (Paraneoplastic Syndrome) .

What are the symptoms of Encephalitis? How do you recognize it?

The symptoms of this disease can vary depending on the type of encephalitis. Symptoms of encephalitis caused by an infection usually appear sooner than those of autoimmune encephalitis.

Early symptoms of encephalitis caused by an infection:

• Confusion: Loss of consciousness, a feeling of not understanding what is happening.
• Drowsiness: Feeling sleepy all the time.
• Fatigue: Too tired to do anything.
• Headache: A severe headache may occur.
• High fever: The body becomes hot and has a high fever.
• Loss of consciousness: Sometimes, loss of consciousness is possible.
• Mild to moderate neck stiffness: It is difficult to bend the neck, and it feels stiff.
• Nausea and vomiting: Stomach upset, feeling like vomiting.
• Seizure: Can come on like a fit.

(Autoimmune Encephalitis) is a type that develops a little more slowly. Some of the symptoms mentioned above may also occur in this case. However, in addition, other symptoms related to the nervous system are also shown. They are:

• Memory issues: Forgetting things, having difficulty remembering old things.
• Noticeable personality changes: Suddenly becoming angry, not being the same person as before.
• Speech issues: Slurred speech, difficulty speaking.
• Weakness or loss of movement in some parts of your body: It may feel like an arm or leg is going numb.

The most important thing: Both types of encephalitis, the infectious type and the autoimmune type, can be life-threatening. If you or someone you know has these symptoms, take them to a hospital immediately. Or call 911. This is not something to take lightly.

How is encephalitis diagnosed? What tests are done?

When you see a doctor with these symptoms, they will first do a physical examination. They will ask you about your symptoms and how long they have been present. Then they may do some tests, such as:

• Blood tests: This may include a (CBC - Complete Blood Count) , which is a test that looks at the types of cells in the blood, and a (CMP - Comprehensive Metabolic Panel) , which is a test that looks at important chemicals in the body.
• Imaging tests: These tests help to see inside the brain.
• (CT - Computed Tomography) scan
• (MRI - Magnetic Resonance Imaging) scan
• Sometimes a special scan called (MEG - Magnetoencephalography) .
• Lumbar puncture: This involves taking a small amount of fluid (cerebral spinal fluid) from your spine and examining it. This is very important to determine if there is an infection or inflammation in the brain.
• Neurological examination: A special test that looks at how your nervous system is working.

These tests are what allow doctors to determine exactly whether you have encephalitis and what the cause is.

What are the treatments for encephalitis?

Doctors treat the underlying cause of the disease and control the symptoms that have developed. Most people with encephalitis are treated in the hospital. This allows them to monitor their symptoms and take action quickly if they get worse. Treatment includes:

• Antiseizure medication: These medications are given to control seizures in conditions such as autoimmune encephalitis.
• Antiviral medications: If it is determined that encephalitis is caused by a virus, medications such as Acyclovir (Zovirax®) are prescribed.
• Breathing assistance: If the condition (encephalitis) becomes severe, breathing may become difficult. In that case, you may need to give extra oxygen or connect to a machine called (mechanical ventilation) to help you breathe.
• Corticosteroids: Both viral and autoimmune encephalitis cause swelling in the brain. These steroid-type medications reduce the swelling and reduce the pressure on the brain.
• Enteral nutrition: If the condition (encephalitis) becomes severe and you lose consciousness, you are unable to eat. In that case, nutrition is provided through a tube (tube feeding).
• Immune globulin: This is a special treatment given for Autoimmune Encephalitis.
• Intravenous (IV) fluids: This helps prevent dehydration.
• Mental health support: Encephalitis can cause memory problems and personality changes. It is very important to seek advice from a clinical psychologist at this time.
• Physical therapy: This disease can cause loss of balance in the body. These can be corrected with the help of a physical therapist.
• Plasmapheresis: This is another special treatment for Autoimmune Encephalitis.
• Speech therapy: If you have difficulty speaking due to effects on the nervous system caused by encephalitis, you can seek the help of a speech therapist.

How long does it take to recover from encephalitis?

(Encephalitis) Symptoms can last from a few days to two to three months. It can take another two to three months to fully recover. This means that this is a long-term, patient recovery process.

Can Encephalitis be completely cured?

Encephalitis can be cured with medications that treat the underlying cause, such as a virus. However, in some cases, encephalitis can cause long-term problems. This may require ongoing medical treatment. For example, behavioral problems, memory loss, or difficulty speaking may persist.

What is the life expectancy of someone with encephalitis?

It really depends on the individual. Although most people who get encephalitis recover, it can be a life-threatening illness. One study showed that about 5% of people treated in a hospital for encephalitis die. In general, how long you live after recovering from encephalitis depends on factors such as:

• Underlying cause: Encephalitis caused by common viruses like Herpes Simplex usually causes less serious problems and therefore does not have a significant impact on lifespan.
• Level of inflammation: If there is severe swelling that affects the nervous system, it can affect lifespan.
• Age and overall health: Young children have a better chance of recovery than adults. Recovery is more challenging for those with pre-existing illnesses and weakened immune systems.
• Early diagnosis and treatment: The sooner treatment is started, the better the outcomes. There is less chance of life expectancy being affected.

If you have (encephalitis), or if you are caring for someone who has it, ask a doctor what to expect.

Can encephalitis caused by an infection be prevented?

Viral infections and insect-borne viruses are the main causes of encephalitis. So, there are things you can do to reduce your risk.

• Getting vaccinated: Make sure you have all your vaccinations on time. Ask your doctor which vaccines are recommended for you.
• Protection from mosquitoes:
• Wear protective clothing: In the summer, wear light, long-sleeved shirts and long pants. Wear a hat that covers both ears.
• Use insect repellent: Choose an insect repellent that contains DEET . Follow the instructions on the label exactly.
• Keep your surroundings dry: Mosquitoes lay eggs in areas where water is stagnant. Don't let water collect in places like flower pots and open garbage cans. Dry such areas and apply an insecticide.
• Use screens and fans: Screening windows will reduce the number of mosquitoes entering your home. If there are mosquitoes inside your home, running a fan will make it harder for mosquitoes to stay in one place, reducing the number of mosquitoes that bite.

How do I take care of my health? (During recovery)

It takes time for the brain to heal after encephalitis. So it's like running a marathon, you have to take it slow. Here are some suggestions that can help you on your recovery journey:

• Pace yourself: You may feel extremely tired for months after you have encephalitis. So, focus on the things that need to be prioritized, like your family, and take some time off from other activities.
• Get your rest: Go to bed at a set time, cut down on caffeine and alcohol, etc. Get into the habit of getting a good night's sleep.
• Maintain a healthy diet: Include lean meats, whole grains, leafy green vegetables, and fruits in your diet. The Mediterranean diet can be a good option.
• Develop an exercise routine: Regular exercise can help you cope with the challenges that come after encephalitis.
• Share your situation: You may still be recovering, but you may appear healthy on the outside. Tell your friends and family why you're taking it a little slower.

When should I see a doctor?

If you have encephalitis, tell your doctor if you notice any changes that may indicate your condition is getting worse. Also, go to the emergency room immediately if you experience symptoms such as confusion, significant personality changes, difficulty speaking, weakness, or inability to move your limbs.

Encephalitis is a serious illness that can have long-term effects. It can take months, even years, to fully recover. Unlike a physical injury, the brain is not something we can see or feel as it heals. When you are still struggling with fatigue and nervous system problems, others may think you are completely recovered. If you are in a similar situation, take the time to explain to others how encephalitis still affects you.

Finally, things to remember (Take-Home Message)

So, now you probably understand that Encephalitis is a serious condition that affects the brain. But, don't panic. The most important thing is to be aware of this.

The most important thing is to seek medical advice as soon as symptoms appear. The sooner you recognize and start treatment, the greater your chances of recovery.

• Remember, simple things like protecting yourself from mosquitoes and getting vaccinated properly can help prevent these dangerous diseases.
• It is very important to be patient, listen to yourself, and follow medical advice during your recovery.
• If you or someone you know has any further questions about this, don't hesitate to talk to a doctor.
