Patient outcome following encephalitis and in particular following autoimmune encephalitis is not well understood. It is only over the last 15 years that we knew, became able to test for, and identify some of these autoimmune causes of encephalitis and so there currently only a small and emerging literature about patient outcomes.
Many papers that talk about or refer to patient outcome look quite early on in the patient pathway and often when they talk about outcome they mean immediate clinical outcome and not how patients are, if they survive, several months or years down the line. Therefore we don’t actually have a good handle yet on autoimmune patient outcomes nor their quality of life. Yet, most papers agree that much more needs to be done to assess long-term outcome and quality of life in autoimmune encephalitis patients. One further point of importance is that some complications of AE might not appear until several months or years down the line.
