Encephalitis vs. Encephalopathy: What’s the Difference and Can Vaccines Cause Them?

Encephalitis and encephalopathy are both conditions that affect the brain, but there is a big difference between the two. Encephalitis is an inflammation of the brain, while encephalopathy is a disorder of the brain caused by damage to or dysfunction of the neurons. Many people use these terms interchangeably, but they are two different neurological conditions and both can be caused by vaccines.

Quick Answer: Encephalitis vs. Encephalopathy

Encephalitis is an inflammation of the brain. It can be caused by a virus, bacteria, or parasites. Encephalitis can also be caused by autoimmune diseases and certain drugs.

Encephalopathy is a general term for any disease that alters the structure or function of the brain. Many different types of encephalopathies exist. Some are degenerative, meaning they get worse over time. Others are acute, meaning they come on suddenly and may only last for a short period.

Vaccines can cause both encephalitis and encephalopathy.


What is encephalitis?

Encephalitis is an inflammation of the brain. It can be caused by a viral infection, bacteria, fungi, or parasites. In some cases, encephalitis can be caused by the body (autoimmune).

The symptoms of encephalitis vary depending on the age of the person suffering from the condition.

  • Infants and young children may have a high fever, seizures, irritability, poor feeding, and vomiting.
  • Older children and adults may have a headache, neck stiffness, confusion, seizures, and memory loss.

In severe cases, encephalitis can lead to coma or death.

What is the treatment for encephalitis?

The treatment for encephalitis depends on the cause. Viral encephalitis is typically treated with antiviral medications. Bacterial encephalitis requires antibiotics to clear the infection. Autoimmune conditions may require immunosuppressive therapy or corticosteroids. Parasitic and fungal infections may

What about autoimmune encephalitis?

Autoimmune encephalitis is a type of brain inflammation caused by the body’s immune system attacking healthy cells in the brain. This can lead to a variety of neurological symptoms, including seizures, memory loss, and changes in behavior.

What are the types of autoimmune encephalitis?

There are many different types of autoimmune encephalitis, each with its own set of symptoms. Some of the most common types include:

Acute disseminated encephalomyelitis (ADEM) is an autoimmune disease that attacks the central nervous system, specifically the myelin sheath that covers and protects nerve cells. The myelin sheath is a layer of insulation around nerve fibers that helps electrical signals move quickly and smoothly from cell to cell. When the myelin sheath is damaged, the electrical signals slow down or become blocked. This can cause a wide range of neurological symptoms.

Sometimes, a person who suffers from ADEM can have inflammation in both the brain and spinal cord, but these are two separate conditions.

What are the symptoms of ADEM?

The most common symptom of ADEM is a sudden onset of neurological problems that develop over 24 to 48 hours. The most common problems include:

– severe headache

– neck stiffness

– fever

– nausea and vomiting

– seizures

– drowsiness or coma

In some cases, ADEM may also cause paralysis, blindness, or memory problems. These symptoms usually peak within a week and then start to improve over the next few weeks. However, it can take months for a person to recover fully from ADEM.

Anti-NMDAR encephalitis is caused by antibodies attacking a protein called NMDA receptors. Symptoms can include hallucinations, psychosis, and seizures.

What are the symptoms of anti-NMDAR encephalitis?

Anti-NMDAR encephalitis is a condition that causes inflammation of the brain. The most common symptoms include:

– headache

– fever

– seizures

– memory loss

– psychosis

– coma

Limbic encephalitis is a type of autoimmune encephalitis. Autoimmune encephalitis is a condition in which the body’s immune system attacks healthy cells in the brain.

What are the symptoms of Limbic Encephalitis?

The most common symptom of limbic encephalitis is seizures. Other symptoms may include headaches, changes in mood or behavior, problems with speech and language, hallucinations, and memory loss.

What are the symptoms of autoimmune encephalitis?

Symptoms of autoimmune encephalitis can vary depending on the type. However, some common symptoms include:


-Memory loss

-Changes in behavior or mood




How is autoimmune encephalitis diagnosed?

A diagnosis of autoimmune encephalitis is often made based on a person’s symptoms and medical history. A brain scan or spinal tap may also be done to look for evidence of inflammation.

What is the treatment for autoimmune encephalitis?

Treatment for autoimmune encephalitis often includes a course of steroids or other immunosuppressive drugs. In some cases, surgery may be necessary to remove the antibodies from the body. With treatment, most people with autoimmune encephalitis make a full recovery. However, some may experience long-term effects, such as memory problems or seizures.

What is vaccine-induced encephalitis?

Vaccine-induced encephalitis is a type of brain inflammation that can be caused by certain vaccines. This is most often seen with the measles, mumps, and rubella (MMR) vaccine or the flu vaccine. Symptoms of vaccine-induced encephalitis are usually mild and resolve on their own within a few days to weeks. In rare cases, more severe symptoms can occur.

What is encephalopathy?

Encephalopathy is a disorder of the brain caused by damage to or dysfunction of the neurons. Encephalopathy can be caused by many different things, including toxins, head injury, stroke, and certain diseases. Alzheimer’s disease and Parkinson’s disease are two examples of degenerative disorders that cause encephalopathy. Symptoms of encephalopathy include memory loss, confusion, changes in mood and behavior, sleepiness, and seizures.

What are acute and chronic encephalopathy?

Encephalopathy can be acute or chronic. Acute encephalopathy comes on suddenly and is often reversible. Chronic encephalopathy develops over time and is not reversible.

What are the treatments for encephalopathy?

The treatment for encephalopathy depends on the underlying cause. In some cases, the condition can be reversed with treatment. For example, if it is caused by a toxin, removing the toxin from the body may improve symptoms. However, in other cases, such as degenerative disorders like Alzheimer’s disease, there is no cure and treatment focuses on managing symptoms.

Can vaccines cause encephalitis or encephalopathy? Yes.

Vaccines can cause encephalitis. This usually happens when the vaccine triggers an autoimmune reaction in the body. The most common vaccine-related encephalitis is called acute disseminated encephalomyelitis (ADEM). It usually occurs a few days to a few weeks after receiving the vaccine. Symptoms of ADEM include headache, fever, and confusion. In severe cases, it can cause paralysis or even death.

Vaccines can cause encephalopathy. The government recognizes vaccine-caused encephalopathy as an injury in the National Vaccine Injury Compensation Program.  Pertussis containing vaccines, Tdap, etc. are the biggest culprits.

Any vaccine has the potential to cause encephalopathy because vaccines are made from viruses, bacteria, or other organisms that can cause inflammation of the brain.

So, what’s the difference between encephalitis and encephalopathy?

Encephalitis is a brain inflammation that can be caused by infection (viral, bacterial, or fungal), autoimmune disease, or exposure to certain toxins. Encephalopathy, on the other hand, refers to any type of chronic or degenerative brain disease. It is important to note that encephalopathy can be caused by many different things, including infections, head injuries, exposure to toxins, and even chronic stress.
