“…Although most reported cases are of women in their 20s, NMOSD can occur in men and in older age [ 19 ]. Some patients diagnosed with WE, having older onset, who do not respond to treatment were reported [ 20 ]. Some of these patients might actually be patients with NMOSD.…”
Both neuromyelitis optica spectrum disorder (NMOSD) and Wernicke's encephalopathy (WE) involve brain lesions. However, their treatments are quite different. In this report, we describe the case of a 29-year-old woman with NMOSD, who presented with clinical and imaging findings similar to those of WE. She was admitted to our hospital with a headache, vomiting, and loss of appetite for two weeks and diplopia for nine days. Magnetic resonance imaging revealed lesions in the area postrema, periaqueductal gray matter, thalamus, and right frontal lobe. Vitamin B1 supplementation was ineffective. The patient was diagnosed with NMOSD because serum aquaporin-4 antibody was detected after admission. Her symptoms improved with immunotherapy. The possibility of NMOSD should be considered in patients with suspected WE.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
