What is Neuromyelitis Optica?

Neuromyelitis optica (NMO) is a rare, lifelong illness that causes problems with your eyesight and your ability to move your body. It is an autoimmune disorder. This means your body’s defense system gets confused and mistakenly attacks healthy parts of your central nervous system.

This condition has gone by a few different names over the years. A long time ago, it was called Devic’s disease, named after Eugène Devic, a doctor who first wrote about it. In 2015, a group of international medical specialists changed the official name to neuromyelitis optica spectrum disorder (NMOSD). Even with the long name, most experts still call it NMO for short.

For a long time, experts thought NMO was just a rare version of multiple sclerosis (MS). Today, they know for sure that NMO is its own completely separate condition.

Who does neuromyelitis optica affect?

NMO is much more common in females than in males. In fact, about 80% to 90% of all people who get NMO are female. It most often shows up in adults who are between 30 and 40 years old. Kids rarely get it, making up only about 5% of all cases.

People of any race or background can get NMO, but it does not hit every group equally. It happens more often in people of African descent, and it can also heavily affect people of Asian descent.

How common is neuromyelitis optica?

NMO is a very rare condition. On average, only about 0.3 to 4.4 people out of every 100,000 have it. This means there are only a small number of cases across the globe compared to other common sicknesses.

How does neuromyelitis optica affect my body?

To understand how NMO hurts the body, it helps to look at how your nervous system is built. Your central nervous system is made up of your brain and your spinal cord. The nerves that let you see, called optic nerves, are actually part of your brain too. The rest of the nerves that spread out to your arms, legs, and toes make up your peripheral nervous system.

Your nervous system sends messages back and forth using tiny electrical and chemical signals. These signals travel through special nerve cells called neurons.

• The Axon: Every neuron has a long, cable-like part called an axon that carries electrical signals away from the cell body toward its end.
• Axon Terminals & Synapses: At the end of the axon are tiny branches called axon terminals. These terminals release chemical messengers across a microscopic gap—called a synapse—to communicate with neighboring cells.
• Myelin: Axons are wrapped in a thin, fatty coating called myelin. Myelin protects the nerve and acts like insulation on an electrical wire, helping signals travel fast.

NMO is a demyelinating disease that damages the protective myelin sheath. Without myelin, the nerve fiber is left bare, making it more susceptible to injury or dysfunction. NMO primarily attacks neurons in two main areas: the optic nerves that connect your eyes to your brain and your spinal cord, which serves as the main highway for nerve signals.

What are the symptoms of Neuromyelitis Optica?

NMO causes symptoms in "attacks," meaning the problems appear and disappear. These flare-ups can last for days or even months. The attacks can be very strong and sometimes cause lasting damage, so some symptoms might remain even after the attack ends.The symptoms fit into three main groups:

Optic neuritis

This happens when your optic nerves get swollen and inflamed. Your eyes collect light and send signals through these nerves so your brain can create a picture. When the nerve swells up, there is not much room for it inside your head, so the swelling presses hard on the nerve. It is a lot like falling asleep on your arm until it goes numb, but it happens to your eyesight. Symptoms can hit one eye or both, causing:

• Eye pain: This usually hurts more when you move your eyes.
• Blurred vision: Your sight might get fuzzier when you exercise or move a lot.
• Partial vision loss or blindness: You might lose part or all of your sight in one eye, see things dimly, or have trouble telling colors apart.
• Trouble seeing in low light: It can get very hard to see in dark rooms or drive at night.

Myelitis

This is swelling in your spinal cord. The swelling blocks the electrical messages trying to travel up to your brain or down to your muscles. If it blocks all messages, it is called transverse myelitis. The symptoms depend on where the swelling is located, and they include:

• Muscle weakness or paralysis: This makes it tough to use your hands, walk, or stand up. If the swelling happens in your neck, it can weaken the muscles you use to breathe, which is very dangerous.
• Spasticity: This happens when muscles tighten up and flex completely on their own because they are not getting the right control signals from the brain.
• Pain: The swelling itself can hurt, or it can trick the nerves into sending false pain signals to your brain.
• Incontinence: You might lose control of your bladder or bowels, making it hard to control when you pee or poop.
• Sexual dysfunction: The swelling can block signals to your reproductive organs.

Brain function disruptions

It is unusual for NMO to attack the main parts of the brain, but it can occur if it affects the brainstem or hypothalamus. The brainstem sits at the lower back of your head and controls automatic jobs you do not have to think about, like breathing and blood pressure. If NMO attacks the brainstem or hypothalamus, it can cause:

• Uncontrollable hiccups.
• Uncontrollable itching.
• Nausea and vomiting that happen without a clear reason.
• Hearing loss.
• Double vision or other problems with control of your eye movements.
• Facial paralysis.
• Dizziness or spinning sensation.
• Difficulty with balance or coordination.
• Nerve-based pain that you feel in your face.

Just above the brainstem is your hypothalamus. This structure also handles automatic body processes. When NMO affects it, this can cause other body systems to malfunction, such as causing excessive daytime sleepiness.

What causes neuromyelitis optica?

Experts do not yet fully understand why people develop NMO. Some of the main reasons include:

• Immune system malfunctions: Your immune system is supposed to fight off bad germs, but in NMO, it makes proteins called antibodies that attack your own body by mistake.
• Aquaporin-4 (AQP4) antibodies: About 80% of people with NMO have an antibody that attacks a cell protein called AQP4. This protein normally balances water in your nerve cells, and attacking it damages the cells.
• Myelin oligodendrocyte glycoprotein (MOG) antibodies: Around 6.5% of people have antibodies that attack MOG, a protein that keeps your myelin healthy.
• Idiopathic cases: About 13.5% of people have neither antibody. Doctors call these cases idiopathic, which just means the cause is totally unknown.

Sometimes these immune mistakes occur right after a person recovers from a normal infection. About 15% to 35% of people with NMO were sick with an infection right before their symptoms started.

NMO is also more likely to happen if you already have another autoimmune disease, such as lupus, celiac disease, or Sjögren’s syndrome. While it does not seem to be a disease you directly inherit from your parents, genetics might make certain people more likely to develop it.

Can neuromyelitis optica spread from person to person?

No, NMO is not contagious. It cannot spread from one person to another like a cold or the flu.

How is neuromyelitis optica diagnosed?

Unlike other nerve diseases, NMO has specific tests that can help prove you have it. Doctors use a few different tools together:

• Blood tests: one of the most useful tools. Doctors check your blood to see if you have AQP4 or MOG antibodies.
• Magnetic resonance imaging (MRI) scans: These scans use magnets to take pictures of the inside of your body. An MRI can show specific patterns of swelling in your spinal cord and optic nerves that differ from those seen in MS.
• Physical and neurological examinations: A doctor will check your reflexes, balance, muscle strength, and facial movements to assess how your nerves are firing.
• Personal and medical history: Your doctor will ask many questions about your life, your family, and exactly when your symptoms began.

How is neuromyelitis optica treated, and is there a cure?

There is no cure for NMO yet, but treatments have come a long way. Because it is an autoimmune issue, treatment has two main goals:

• Acute treatment: This treats a sudden attack right when it happens. Doctors use strong anti-inflammatory medicines to stop the swelling quickly and prevent permanent nerve damage.
• Long-term management: This involves taking medicines every day to quiet down your immune system. If your immune system is calm, it cannot launch new attacks on your nerves.

What medications or treatments are used?

The medications or treatments are used to treat neuromyelitis optica -

• Anti-inflammatory drugs: Strong anti-inflammatory medicines like prednisone are used to stop swelling. They are often started through an intravenous (IV) tube in your arm while you are at a medical center, and then changed to daily pills you take at home.
• Plasma exchange (plasmapheresis): If steroids do not stop an attack, a machine can wash your blood. It removes your plasma (the liquid part of your blood containing the bad antibodies) and replaces it with clean donor plasma.
• Intravenous immunoglobulin (IVIG): This is an IV treatment filled with healthy antibodies from donors. These good antibodies help stop your own immune system from attacking you.
• Immune-suppressing drugs (immunosuppressants): These are long-term medicines you take as daily pills or get as regular IV infusions to keep your immune system weak enough so it leaves your nerves alone.

What are the possible complications or side effects of the treatments?

The biggest side effect of long-term NMO drugs is that they lower your body's natural defenses. Your immune system is supposed to fight off viruses, bacteria, and even bad cells like cancer. When you take these drugs to protect your nerves, you also lose some ability to fight off normal bugs.

People taking these medicines have a higher risk of getting severe infections or developing tumors. Because of this, you have to be very careful to avoid getting sick and stay up to date on vaccines for things like the flu, COVID-19, and pneumonia.

How soon after treatment will I feel better, and how long will it take me to recover from treatment?

The treatment and recovery timeline for NMO can vary because many factors play a role. Your doctor is the best source of information on this. They can tell you the timeline most likely for your case and what you can do to help the process.

What can I expect if I have neuromyelitis optica?

NMO attacks usually hit suddenly. You might notice your vision worsening over a couple of weeks, with eye pain and blind spots. Severe swelling in your spine can cause sudden muscle weakness or trouble peeing. If the swelling hits your neck, it can make breathing hard, which requires emergency help.

Because it is a lifelong condition, you will likely need to take immune-weakening medicines for a very long time to prevent these flares.

How long does neuromyelitis optica last?

For almost everyone with AQP4 or MOG antibodies, NMO is a lifelong condition. You will have to manage it for the rest of your life. About 10% to 20% of people—usually those who do not have either antibody—only ever experience one single attack and never have another one. However, because doctors cannot predict the future, they usually recommend staying on medicine anyway.

What’s the outlook for neuromyelitis optica?

In the past, the outlook for NMO was not very good. Today, things are much brighter because we understand the immune system better. Modern medicines can cut down the number of repeat attacks by 72% to 88%. The five-year survival rate is now very high, ranging from 91% to 98%.

If someone has a lot of attacks, they are more likely to have lasting trouble with walking or seeing. About 22% of people completely recover all their abilities after an attack, 7% do not get better at all, and the other 71% get mostly better but have to live with some lasting symptoms.

How can I reduce my risk of developing neuromyelitis optica, and is it preventable?

Because NMO occurs randomly and its causes are still somewhat of a mystery, there is no known way to prevent it or reduce your risk of developing it.

How do I take care of myself?

Living with NMO takes some work, but you can do it by focusing on a few key steps:

• Take your medication: Even if you feel perfectly healthy and haven't had an attack in years, keep taking your pills. Stopping your medicine can trigger a brand-new attack.
• See your provider as recommended: Go to your regular checkups. Your doctor will run routine blood tests to see how active your immune system is and make sure your medication doses are correct.
• Take precautions to avoid getting sick: Since your medicine lowers your body's defenses, wash your hands with soap and water frequently or use hand sanitizer. Your doctor might also suggest wearing a face mask in crowded rooms.

When should I call my healthcare provider?

Because your immune system is suppressed, minor infections can quickly become major problems. You should get in touch with a doctor right away if you experience:

• Severe fatigue or weakness.
• Nausea and vomiting.
• Unexpected weight changes.
• Urinating more often than usual, feeling lower back pain, or pain or burning while urinating.
• Symptoms of upper respiratory infections, such as coughing, sneezing, runny nose, or sore throat.
• Other signs of infection, such as fever, chills, and muscle aches.
