Quick Answer: How Can You Tell The Difference Between Meningitis And Encephalitis Clinically?

What is the most common cause of encephalitis?

The most common causes of viral encephalitis are herpes simplex virus types 1 and 2, varicella zoster virus and enteroviruses, which cause gastrointestinal illness.

Encephalitis can also result from certain viruses carried by mosquitoes, ticks and other insects or animals such as: West Nile virus..

What are the long term effects of encephalitis?

Some people experience longer-term effects of encephalitis. Longer-term symptoms can include physical problems, memory problems, personality changes, speech problems, and epilepsy.

What does a brain infection feel like?

Encephalitis often causes only mild flu-like signs and symptoms — such as a fever or headache — or no symptoms at all. Sometimes the flu-like symptoms are more severe. Encephalitis can also cause confused thinking, seizures, or problems with movement or with senses such as sight or hearing.

Is Encephalitis an emergency?

Acute encephalitis is a neurological emergency which can cause severe disability or death, but can often be treated if diagnosed promptly.

What is the test for encephalitis?

Diagnostic tests that may be performed to confirm the diagnosis of encephalitis may include the following: Magnetic resonance imaging (MRI). A diagnostic procedure that uses a combination of large magnets, radiofrequencies, and a computer to produce detailed images of organs and structures within the body.

How do you get encephalitis and meningitis?

Meningitis is an infection of the meninges, the membranes that surround the brain and spinal cord. Encephalitis is inflammation of the brain itself. Anyone can get encephalitis or meningitis. Causes of encephalitis and meningitis include viruses, bacteria, fungus, and parasites.

Does encephalitis show up in bloodwork?

Samples of blood, urine or excretions from the back of the throat can be tested for viruses or other infectious agents. Electroencephalogram (EEG). Electrodes affixed to your scalp record the brain’s electrical activity. Certain abnormal patterns may indicate a diagnosis of encephalitis.

How fast does encephalitis progress?

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 can you tell the difference between meningitis and encephalitis?

Meningitis is an inflammation of the three membranes that cover the brain and spinal cord (the meninges). Encephalitis is an inflammation of the brain. Meningoencephalitis is an inflammation of both the brain and the meninges.

Is meningitis A encephalitis?

Meningitis is an infection of the meninges, the membranes that surround the brain and spinal cord. Encephalitis is inflammation of the brain itself. Anyone can get encephalitis or meningitis. Causes of encephalitis and meningitis include viruses, bacteria, fungus, and parasites.

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.

Does encephalitis go away by itself?

In mild cases of encephalitis, the inflammation will likely resolve in a few days. For people who have severe cases it may require weeks or months for them to get better. It can sometimes cause permanent brain damage or even death.

Can a CT scan detect encephalitis?

Brain scans A scan of the brain can help show whether you have encephalitis or another problem such as a stroke, brain tumour or brain aneurysm (a swelling in an artery). The 2 main types of scan used are: a CT scan. an MRI scan.

Will encephalitis show on MRI?

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 long is treatment for encephalitis?

Treating the cause If a cause of encephalitis is found, treatment will start straight away. Possible treatments include: antiviral medicine – used if encephalitis is caused by the herpes simplex or chickenpox viruses; it’s usually given into a vein three times a day for 2 to 3 weeks.

Is encephalitis or meningitis worse?

Bacterial meningitis and viral encephalitis may be rapidly fatal, even in healthy persons. Survivors may suffer lasting neurological sequelae, including memory loss and seizures. Viral meningitis, by contrast, gives patients a bad headache and a stiff neck, but uneventful recovery is the rule.

How long can you have encephalitis without knowing?

Symptoms typically appear 7-10 days following infection and include headache and fever. In more severe cases, confusion and disorientation, tremors, convulsions (especially in the very young), and coma may occur.
