Neuromyelitis Optica
Neuromyelitis optica, or Devic’s disease, occurs when the immune system attacks and destroys myelin in the spinal cord and eye. This can result in symptoms and complications such as:
- Optic neuritis
- Transverse myelitis
- Vision loss
- Weakness, pain, or both in the limbs
- Bladder and bowel problems
- Nausea and vomiting
Many people with neuromyelitis optica have episodes of symptoms that can occur months or years apart. If neuromyelitis optica affects breathing, it can be life threatening.
The exact cause of the disease is still unknown. However, it is usually traced to personal or family history of autoimmune conditions.
