- High fever.
- Severe headache.
- Stiff neck and back.
- Photophobia (sensitivity to bright light)
- Sonophobia (sensitivity to sound)
- Vomiting.
- Drowsiness and confusion.

What is the most common cause of meningoencephalitis?
The most common causes of bacterial meningoencephalitis include: Streptococcus pneumoniae: A bacteria commonly found in the nose and throat. Haemophilus influenzae (HIB): A type of bacteria that commonly causes respiratory infections, and which is preventable by vaccine.
Which virus causes encephalomyelitis?
In humans, the viruses most commonly identified as causes of viral encephalomyelitis are herpesviruses and RNA viruses in the enterovirus (e.g., polio, enterovirus 71), rhabdovirus (e.g., rabies), alphavirus (e.g., eastern equine, Venezuelan equine, and western equine encephalitis), flavivirus (e.g., West Nile.
Can encephalitis cure itself?
Recovery. 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.
How long do encephalitis symptoms last?
Long-term outlook for viral encephalitis The severity of viral encephalitis depends on the particular virus and how quickly treatment was given. Generally, the acute phase of the illness lasts around one or two weeks, and the symptoms either disappear quickly or subside slowly over a period of time.
How is meningoencephalitis diagnosed?
Tests in hospital a physical examination to look for symptoms of meningitis. a blood test to check for bacteria or viruses. a lumbar puncture – where a sample of fluid is taken from the spine and checked for bacteria or viruses. a CT scan to check for any problems with the brain, such as swelling.
Can MRI detect virus encephalitis?
Laboratory investigations, imaging, and cerebrospinal fluid analysis are crucial in the diagnosis of encephalitis. Magnetic resonance imaging (MRI) findings may be nonspecific or specific and plays a major role in the diagnosis of encephalitis and predicting the possible cause.
How is encephalitis diagnosed?
Tests for encephalitis can include:
- Neuroimaging, such as a brain MRI or CT scan.
- A lumbar puncture (spinal tap) to check for signs of infection in the brain or spinal cord.
- Electroencephalogram (EEG) to look for seizures or specific patterns of electrical activity in the brain.
What is the treatment of meningoencephalitis?
Acute bacterial meningitis must be treated immediately with intravenous antibiotics and sometimes corticosteroids. This helps to ensure recovery and reduce the risk of complications, such as brain swelling and seizures. The antibiotic or combination of antibiotics depends on the type of bacteria causing the infection.
Can you have encephalitis without fever?
Sometimes there is no known cause. Encephalitis may cause only mild flu-like signs and symptoms — such as a fever or headache — or no symptoms at all.
