Anti-N-methyl-D-aspartate receptor encephalitis: A case report and review of the literature.

Anti-N-methyl-D-aspartate receptor encephalitis is a well characterized immune-mediated encephalitis. It is increasingly being recognized as one of the common causes of encephalitis, but is frequently misdiagnosed especially in resource-constrained settings. With a simple test available to diagnose the disorder and prospects of good recovery following early immunotherapy, the disorder should be kept as a differential diagnosis in patients presenting with unexplained behavioral/psychiatric symptoms and progressive encephalopathy with movement disorders.
