# Neuromyelitis Optica: A Deceiving Disorder of Demyelination

## TL;DR

Neuromyelitis optica is an autoimmune disorder affecting the optic nerves and spinal cord, often linked to aquaporin-4 antibodies and requiring prompt treatment to prevent permanent damage.

## Contribution

The paper presents a case study of an African-American female with NMO, highlighting its clinical presentation and management.

## Key findings

- NMO is associated with aquaporin-4 antibodies and affects the optic nerves and spinal cord.
- Symptoms include myelitis, optic neuritis, vomiting, and hiccups.
- Early treatment with high-dose steroids is crucial to prevent CNS damage.

## Abstract

Neuromyelitis optica (NMO), also known as Devic syndrome, is an autoimmune inflammatory and demyelinating disorder that affects the optic nerves and spinal cord. It is believed to be attributed to aquaporin-4 antibodies, a water channel expressed on astrocytes. It commonly presents with isolated or recurrent attacks of myelitis and optic neuritis. Intractable vomiting and hiccups may also be seen as symptoms. Acute treatment is often achieved with high-dose steroids and is imperative to prevent permanent central nervous system damage. Relapse prevention is achieved using long-term immunosuppression. This paper examines the case of an African-American female who presented with ascending lower extremity weakness.
