Virus Infection In Brain



Encephalitis is an inflammation of the brain , which is usually caused by a virus known as viral encephalitis .
Encephalomyelitis is an inflammation of the brain and spinal cord , which is also caused by a virus .
Aseptic meningitis is an inflammation of the meninges ( membranes surrounding the brain and spinal cord ) , which is usually caused by a virus .

CAUSE
Several different viruses can infect the brain and spinal cord , including the viruses that cause herpes and mumps ( mumps ) .
Some of these infections is the plague , and the other insect-borne .

Some viruses are not specifically infects the brain and spinal cord , but they cause an immune reaction which indirectly cause inflammation in the area .
Such encephalitis ( encephalitis parainfeksiosa or post - infectious encephalitis ) can occur after measles , chicken pox or measles Germany .
The inflammation usually occurs within 5-10 days after viral disease and can cause serious damage to the nervous system .

Perandangan brain can sometimes occur weeks , months or years after the virus infection .
Examples are panensefalitis subacute sclerotic , which is a brain inflammation that sometimes occurs after measles and usually affects children .

SYMPTOMS
# Brain infection because the virus can cause three different symptoms : mild infection , causing fever and malaise , often without other typical symptoms
# Fever with headache , vomiting , weakness and stiff neck
# There was disruption of normal brain function that cause changes in personality , seizures , weakness on one or more parts of the body , confusion , drowsiness which could develop into a coma , and other symptoms of meningitis .

Certain viruses provide any additional symptoms .
An example is the herpes simplex virus , which often causes recurrent seizures at an early stage of encephalitis . In addition to white blood cells , cerebrospinal fluid also contains red blood cells . These viruses also cause swelling in the temporal lobe , which can be seen on MRI skening .

Diagnosis
Almost always check ntuk lumbar puncture cerebrospinal fluid .
In viral infections , increased white blood cell count , but was not found bacteria .
It is very difficult to breed virus from cerebrospinal fluid and takes a long time .

Immunological examination conducted to measure the levels of antibodies against the virus .

To ensure that the cause of the onset of symptoms is not due to brain abscess , stroke or structural abnormalities ( eg, tumor , hematoma or aneurysm ) , then do a CT scan or MRI .
