is the word used to describe inflammation of the brain. This condition
can cause problems with the brain and spinal cord function. The inflammation
causes the brain to swell, which leads to changes in the person's
neurologic condition, including mental confusion and seizures. Some
cases are mild, short and relatively benign and patients have full
recovery. Other cases are severe.
The acute phase of encephalitis may last for several weeks, with
gradual or sudden resolution of fever and neurological symptoms.
Neurological symptoms may require months, and often years before
full recovery. With early diagnosis and prompt treatment, most patients
recover. There are many types of encephalitis, most of which are
caused by viral infection. It can occur at any age and is usually
the result of a viral infection.
There are two main types of encephalitis:
1. Acute viral encephalitis (AVE) a direct viral attack on the brain.
2. Post Infectious Encephalitis (PIE) an autoimmune condition whereby the body's immune system attacks the brain following a viral infection
elsewhere in the body.
