Abstract

Neuromyelitis optica spectrum disorder (NMOSD) can present with various symptoms including optic neuritis, transverse myelitis, and area postrema syndrome. However, acute memory loss is an uncommon clinical presentation of NMOSD. We report a patient with NMO-IgG-antibody-positive NMOSD presenting with only acute memory loss, which suggested the presence of bilateral thalamic lesions. This case indicates that NMOSD needs to be considered in the differential diagnosis of acute memory loss.
