Anti-N-methyl-D-aspartate receptor encephalitis coexisting with neuromyelitis optica spectrum disorders: two cases report / 中华神经科杂志

ABSTRACT

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis and neuromyelitis optica spectrum disorders (NMOSD) are central nervous system diseases mediated by autoimmune antibodies. With the improvement of diagnosis and treatment, the reports of the two diseases appearing in the same patient are increasing. To strengthen the understanding of this kind of comorbidity, two cases of anti-NMDAR-encephalitis coexisting with NMOSD admitted in our hospital were reported. The clinical manifestations and imaging examination of the two patients showed the evidence of involvement of both brain and spinal cord. The anti-NMDAR antibody and anti-aquaporin 4 antibody tests were positive. In addition, gamma globulin or corticosteroid impulse therapy was effective in the treatment of two patients.
