Neuromyelitis optica(NMO) is an autoimmune disease that starts in thecentral nervous system. It affects the brain and spinal cord. You may also hear it called Devic disease or neuromyelitis optical spectrum disorder.

This article discusses the causes, symptoms, and risks of untreated symptoms of NMO. It also covers diagnosis, treatment, and NMO resources and support.

Central Nervous System and Neuromyelitis Optica

An estimated 10% to 20% of people with NMO also have another autoimmune disorder, such as:

NMO: What’s the Average Age?The average age of onset for NMO is 41 years old. It’s also more common among females. Both of these characteristics are similar to otherautoimmune diseases.

NMO: What’s the Average Age?

The average age of onset for NMO is 41 years old. It’s also more common among females. Both of these characteristics are similar to otherautoimmune diseases.

NMO Symptoms

Even with treatment, one study found, 64% of people with NMO still experienced moderate to severe pain.

Neuromyelitis Optica vs. Multiple SclerosisNMO is often confused withmultiple sclerosis(MS); however, they are separate conditions. Here are some key differences:NMO attacks are usually more intense than those of MS.When attacking the eyes, NMO often affects both eyes. MS is more likely to affect just one eye.NMO typically affects the optic nerve and spinal cord. MS often affects the optic nerve, spinal cord, and other brain areas. (Sometimes, NMO also will cause lesions in specific parts of the brain.)NMO does not cause cognitive damage like MS, such as memory changes.

Risks of Untreated NMO Symptoms

Although there is no cure for NMO, the available treatments can help control symptoms and slow disease progression.

As the attacks caused are unpredictable, untreated NMO can raise your risk for further damage to the body. If left untreated, up to 30% of those with NMO will die within the first five years of illness. The most common reason for this isrespiratory failure.

Receiving a Neuromyelitis Optica Diagnosis

One goal of diagnosing NMO is to distinguish it from MS.A healthcare provider will do the following to diagnose the condition:

How Quickly Do NMO Symptoms Progress?

Neuromyelitis optica progresses at different rates in each individual. When you have NMO, you’ll have attacks, also called relapses. These may occur days, weeks, or months apart. New damage can occur from each relapse. Disabilities can occur over time with repeated relapses.

Types of Neuromyelitis Optica Treatment

For an acute attack of NMO, healthcare providers typically will treat you using the following:

What Is Plasma Exchange?To do plasma exchange, a healthcare provider removes some blood from your body and separates the blood cells from the fluid (plasma) with a special machine. Then, they combine the blood cells with a replacement solution and return them to the body. Plasma exchange may help those with acute, severe attacks who do not get enough of a response to corticosteroids.

Long-term treatment options for NMO include different medications, including:

One common treatment is azathioprine or mycophenolate mofetil and a low dose of corticosteroids. Adults who are positive for anti-aquaporin-4 antibodies may also receive one of the following immunotherapy drugs now available to treat NMO:

Neuromyelitis Optica Resources and Support

There is a variety of organizations and support groups to help those with NMO and their families. Here are some places for additional resources and support:

Specialists Who Work With Neuromyelitis Optica Patients

Because NMO affects body systems, a range of health specialists help treat the condition, including:

Summary

NMO is a rare autoimmune condition that can significantly impact your quality of life. It is often confused with MS since it presents similarly, but there are important differences between the two conditions.

Although there is no cure, treatment options are available to help manage your symptoms. If you or someone you care for has been diagnosed with NMO, follow your healthcare providers' instructions and seek additional support when necessary.
