We would ask that prior to proceeding further in your search for information about Encephalitis you take a few moments to read and consider the comments below.

In some instances where people are affected by Encephalitis the long-term prognosis can be very good, with many people coming through the illness with little or no difficulties. However because there are occasions where more severe problems can occur, we have had to make our information as broad and far-reaching as possible. Therefore the details provided in the forthcoming web pages are fairly extensive. Taking this into account we would ask that anyone seeking information consider the following factors.

The difficulties stated in the information are not reflective of every situation where Encephalitis is involved and that some of the information stated may not be relevant to your situation.

Taking into account the emotional strain that a diagnosis of Encephalitis may bring coupled with the amount of information available through our website consideration may be required into gauging how much information is accessed at any one time.

The information provided on the website is designed to support, not replace, the relationship that exists between a patient/site visitor and his/her physician.

The Illness

Encephalitis is inflammation of the brain. The inflammation is caused either by an infection invading the brain (infectious); or through the immune system attacking the brain in error (post-infectious or autoimmune Encephalitis).

We have produced a book,  Encephalitis in Adults a Guide,  which you can download for more information. If you would like a paper version of this please contact the office on 01653 699599 or email support@encephalitis.info.
