Anti-N-Methyl-D-Aspartate Receptor Encephalitis Presenting Progressive Dyslexia: A Case Report

ABSTRACT

BACKGROUND: Anti-N-methyl-D-aspartate (anti-NMDA) receptor encephalitis was discovered less than 10 years ago. Its symptoms and characteristics are not well-defined yet. We experienced a case of anti-NMDA receptor encephalitis with phonemic paraphasia and acalculia that were not classical characteristics. CASE REPORT A 44-year-old woman started to show dyslexia, phonemic paraphasia, and dyscalculia. These symptoms were gradually worsening for over 30 days. Various brain images were not helpful for primary diagnosis. Anti-NMDA receptor encephalitis was confirmed in two different laboratories. The patient started to recover with various immunosuppressive therapies. CONCLUSIONS: Anti-NMDA receptor encephalitis can have various symptoms, including phonemic paraphasia and acalculia.
