What viruses affect the brain?

Encephalitis is most commonly due to viruses, such as herpes simplex, herpes zoster, cytomegalovirus, or West Nile virus. It can occur in the following ways: A virus directly infects the brain. A virus that caused an infection in the past becomes reactivated and directly damages the brain.

What causes virus in the brain?

Encephalitis is most often due to a virus, such as: herpes simplex viruses, which cause cold sores and genital herpes (this is the most common cause of encephalitis) the varicella zoster virus, which causes chickenpox and shingles. measles, mumps and rubella viruses.

Can flu cause neurological problems?

Influenza can be associated with various neurologic problems: encephalopathy (a state of confusion), seizures, neuropathy, as well as others. These complications most frequently occur in children, although cases of neurologic illness associated with adult influenza certainly occur.

What is the survival rate of encephalitis?

Some forms of encephalitis are more severe than others. For example, herpes simplex encephalitis (HSE) has a mortality rate of up to 30% even with specific anti-viral treatment, and 70-80% without the treatment. When death happens it is usually because of the brain swelling as a result of its severe inflammation.

Can a virus cause mental confusion?

Encephalitis is inflammation of the active tissues of the brain caused by an infection or an autoimmune response. The inflammation causes the brain to swell, which can lead to headache, stiff neck, sensitivity to light, mental confusion and seizures.

Does brain inflammation go away?

A common cause of brain inflammation is head injury. Injuries cause immune cells to turn on in order to begin the healing process. But unlike immune cells in the body, the brain’s immune cells do not turn off. This means brain inflammation can continue to be a problem long after the injury.

Can you fully recover from encephalitis?

Many people who have encephalitis fully recover. The most appropriate treatment and the patient’s chance of recovery depend on the virus involved and the severity of the inflammation. In acute encephalitis, the infection directly affects the brain cells.

Can CT scan detect brain infection?

A CT of the brain may be performed to assess the brain for tumors and other lesions, injuries, intracranial bleeding, structural anomalies (e.g., hydrocephalus , infections, brain function or other conditions), particularly when another type of examination (e.g., X-rays or a physical exam) are inconclusive.

Can you get a virus in your brain?

Encephalitis (en-sef-uh-LIE-tis) is inflammation of the brain. There are several causes, but the most common is a viral infection. Encephalitis often causes only mild flu-like signs and symptoms — such as a fever or headache — or no symptoms at all.

Can you recover from a brain infection?

An infected person may have symptoms similar to encephalitis with confusion and delirium. Coma, seizures, paralysis, and other signs of neurologic loss are found in more severe forms. Most people recover within a few days or weeks without any long-term problems.

What does brain swelling feel like?

Symptoms of brain swelling include headache, dizziness, nausea, numbness or weakness, loss of coordination or balance, loss of the ability to see or speak, seizures, lethargy, memory loss, incontinence, or altered level of consciousness.

How long can a brain infection last?

The inflammation of the brain can last from a few days to two or three months. After this, most people find that they make their best recovery from their symptoms within two or three months.

What happens if you get a brain infection?

Infections can also cause inflammation of the layers of tissue (meninges) that cover the brain and spinal cord—called meningitis. Often, bacterial meningitis spreads to the brain itself, causing encephalitis. Similarly, viral infections that cause encephalitis often also cause meningitis.

Can a blood test detect brain infection?

Blood tests may show signs of infection such as elevated white blood cells. If your meningitis is complicated with sepsis (infection of the blood), your blood culture may show the type of bacteria causing the infection as well. Viral meningitis does not typically involve the blood and is not associated with sepsis.
