What is anti-NMDA receptor encephalitis?
Anti-NMDA receptor encephalitis is a neurologic disease first identified by Dr. Josep Dalmau and colleagues at the University of Pennsylvania in 2007. It is an autoimmune disease, where the body creates antibodies against the NMDA receptors in the brain.
What causes NMDA receptor encephalitis?
This condition occurs when the immune system mistakenly targets neurons in the brain, causing inflammation (encephalitis).
Can anti-NMDA receptor encephalitis be cured?
According to the same study, 80% of patients with Anti-NMDA-receptor encephalitis eventually have partial or complete recovery. Some patients took up to 18 months to recover. This study was done in 2013 and focused solely on outcomes in terms of neurologic disability.
What are the symptoms of anti-NMDA receptor encephalitis?
The condition is often clinically recognized in the ensuing psychotic phase, in which delusions, hallucinations, paranoia, and agitation may be exhibited. During this phase, anti-NMDAR encephalitis is often misdiagnosed as a primary psychotic or substance-induced disorder.
Who is at risk for anti-NMDA receptor encephalitis?

Conclusion. Anti-NMDA receptor encephalitis is a newly discovered disorder characterized by prominent psychiatric symptoms, seizures, movement disorders, cognitive dysfunction, and autonomic instability. Treatment should be initiated early with a low threshold to progress to second-line therapies.
Is NMDA encephalitis fatal?
Although anti-NMDA receptor encephalitis is a serious life-threatening disease, the majority of patients who receive prompt diagnosis and treatment go on to make a good recovery. Recovery is generally slow and may occur over months or even years.
Can you live a normal life after encephalitis?
Recovering from encephalitis can be a long, slow and difficult process. Many people will never make a full recovery. Specialised services are available to aid recovery and help the person adapt to any persistent problems – this is known as rehabilitation.

In many cases, the cause of autoimmune encephalitis is unknown. But experts say it can be caused by: Exposure to certain bacteria and viruses, including streptococcus and herpes simplex virus. A type of tumor called a teratoma, generally in the ovaries, that causes the immune system to produce specific antibodies.
How fast does autoimmune encephalitis progress?
Symptoms may fluctuate, but often progress over days to a few weeks. Symptoms can progress to loss of consciousness or even coma. Autoimmune encephalitis may be associated with antibodies to proteins on the surface of nerve cells, or within nerve cells.
Is brain damage from encephalitis permanent?
