A rare case of anti-N-methyl-D-aspartate receptor encephalitis during pregnancy.

Abstract

Anti-N-methyl-D-aspartate (NMDA) receptor encephalitis was first described as a severe form of encephalitis by Dalmau et al in 2006. This is an autoimmune disorder usually associated with paraneoplastic mechanism that manifests as neuropsychiatric disorder affecting mainly women of child-bearing age. Nevertheless anti- NMDA receptor encephalitis is a rare condition during pregnancy. To -date, there have been only four reported cases during pregnancy. We report a case of a 23-year-old primigravida in first trimester pregnancy with altered mental status and multiple neurological symptoms related to anti-NMDA receptor encephalitis. To the best of our knowledge, this is the first reported anti-NMDA receptor encephalitis during pregnancy in Australasia.
