How many types of encephalitis are there?
Encephalitis can be divided into 2 main types:
Encephalitis caused by an infection in the brain
Infectious encephalitis occurs when a virus or other infectious agent directly infects the brain. In many cases of infectious encephalitis the cause cannot be found. When a cause is found it is often a common virus that most children will come into contact with.
Encephalitis caused by autoimmune actions
Autoimmune encephalitis occurs when the immune system mistakes substances inside the brain as a threat and starts attacking them. There are a number of types of autoimmune encephalitis, each type targets a different part of the nerve cell. Autoimmune diseases are triggered by an unwanted process in the body, this could be a viral infection or it could be a tumour.
Encephalitis can also be described by the area of the brain that is affected.
