Neuromyelitis optica

From WikiMD's Wellness Encyclopedia

(Redirected from Devic's syndrome)

Neuromyelitis optica (NMO), also known as Devic's disease or Devic's syndrome, is a heterogeneous condition consisting of the inflammation and demyelination of the optic nerve (optic neuritis) and the spinal cord (myelitis). It can be monophasic or recurrent.

Signs and symptoms[edit | edit source]

The inflammation and damage to the optic nerve can cause visual symptoms in one or both eyes, including sudden loss of vision, pain with eye movement, and reduced color vision. The inflammation in the spinal cord can cause a variety of symptoms, including weakness or paralysis of arms and legs, sensation loss, uncontrollable vomiting and hiccups, and dysfunction of the bowel and bladder.

Causes[edit | edit source]

NMO is thought to occur because of an abnormal response of the immune system. However, the exact cause is unknown. It is not considered a hereditary disease, but certain genes may increase the risk.

Diagnosis[edit | edit source]

The diagnosis of NMO is based on a combination of symptoms, examination findings, and the results of blood tests and imaging studies. The presence of a specific antibody, known as NMO-IgG or AQP4, is strongly associated with NMO.

Treatment[edit | edit source]

There is no cure for NMO, but treatments can help manage symptoms and prevent relapses. These include corticosteroids, immunosuppressive drugs, and a new class of drugs called monoclonal antibodies.

Prognosis[edit | edit source]

The prognosis of NMO varies. Some people recover with minor residual problems, while others may have significant disability. Early diagnosis and treatment can help improve the prognosis.
