  Neuromyelitis optica can cause blindness, weakness in the legs or arms, and painful spasms. It also can cause loss of sensation, vomiting and hiccups, and bladder or bowel symptoms. […] Symptoms of neuromyelitis optica are related to the inflammation that occurs in the nerves of the eye and spinal cord. […] Vision changes caused by NMO are called optic neuritis. These may include: Blurred vision or loss of vision in one or both eyes. Not being able to see color. Eye pain. […] Symptoms related to the spinal cord are called transverse myelitis. These may include: Stiffness, weakness or numbness in the legs and sometimes in the arms. Loss of feeling in the arms or legs. Not being able to empty the bladder or trouble managing bowel or bladder function. A tingling feeling or shooting pain in the neck, back or stomach.

  Symptoms of neuromyelitis optica (NMO) vary between people, and can be mild or severe. […] The symptoms can include: eye pain and problems with your eyesight or your colour vision, in one or both eyes […] sharp, burning or shooting pain (nerve pain) in your back, neck, arms or legs […] weakness, numbness or paralysis in your arms or legs […] muscle spasms (where your muscles suddenly tighten) […] problems with your bladder and bowels, such as incontinence, constipation or not being able to pee […] sexual problems, such as not being able to get an erection or reach orgasm […] vomiting and hiccups. […] Symptoms start over a few hours or days. They usually last a few days or weeks, before gradually improving. Some people recover well with treatment, while others have longer lasting problems. […] It’s common for symptoms to come back, known as relapses. This can happen after a few weeks, months or years. In some people, relapses lead to permanent problems such as sight loss or mobility problems.

  Neuromyelitis optica (NMO) is a disorder of the central nervous system. NMO causes inflammation and damage to the optic nerve and spinal cord. […] NMO may cause different symptoms that range in severity. One main symptom is inflammation of one or both optic nerves (optic neuritis). Optic nerves transmit images from the eyes to the brain. Swelling and inflammation of the optic nerve may cause eye problems such as: Eye pain, Blurred vision, Partial vision loss, Blindness in one or both eyes. Other symptoms include: Inflammation of the spinal cord (myelitis), Pain around the chest and waist, Unexplained hiccups, Persistent nausea or vomiting, Uncontrollable itching, Difficulty in swallowing (dysphagia), Respiratory disorders, Problems with movement and coordination (motor or sensory dysfunction), Inability to hold stool or urine (bowel or bladder incontinence), Brain damage (encephalopathy), Double vision, Sleep disorders such as disturbed sleep, decreased sleep quality, or restless legs syndrome, Sexual dysfunction, Recurrent attacks of visual, motor, and sensory dysfunction, Weakness, numbness, or paralysis of the arms and legs.

  Neuromyelitis optica (NMO) can affect your optic nerve and spinal cord. That can cause symptoms like vision problems and pain or weakness in your limbs. […] NMO causes symptom attacks, meaning that the symptoms come and go. Attacks can last for days to months at a time. These attacks are often severe and can sometimes cause permanent damage. When this happens, the effects might be permanent even after an attack ends. […] The symptoms of NMO break down into three categories: Optic neuritis, Myelitis, and Brain function disruptions. […] Optic neuritis causes inflammation of the optic nerve, causing it to swell. The symptoms of optic neuritis can affect one or both eyes, and the timing of the symptoms can affect one eye after the other or both at the same time. The symptoms include eye pain, blurred vision, partial vision loss or blindness, and trouble seeing in low light.

  Changes in vision (optic neuritis) and symptoms caused by spinal cord inflammation (transverse myelitis) are common in NMOSD. Symptoms caused by optic neuritis include: Loss or blurring of vision in one or both eyes, Loss of color vision, Eye pain. Symptoms caused by transverse myelitis include: Weakness, numbness or loss of sensation, Loss of muscle function, Loss of bowel or bladder control or difficulty emptying the bladder, Spasticity (increased muscle tone or stiffness in the arms or legs), Shooting pain or tingling in the neck, back or abdomen. Other symptoms that commonly occur with an NMOSD relapse include uncontrollable hiccups, nausea and vomiting. […] NMOSD progresses at variable rates and, as with MS, is unpredictable. Each relapse causes new damage, and, over time, relapses can lead to serious disability.

• #6 Neuromyelitis Optica – EyeWiki

  https://eyewiki.org/Neuromyelitis_Optica

  NMOSD typically follows a relapsing and chronic course with recurrent acute attacks of transverse myelitis and/or unilateral or bilateral optic neuritis with only partial or no recovery. […] Transverse myelitis in NMOSD is frequently severe causing a complete spinal cord syndrome involving all three major neurological pathways (motor, sensory, and autonomic). This may result in permanent symptoms and signs (e.g., paraparesis or quadriparesis, paroxysmal tonic spasms, bladder dysfunction, and sensory loss) as well as radiographic progression to spinal cord atrophy. […] Although the optic neuritis in NMOSD superficially may resemble MS, NMOSD related optic neuritis tends to be more severe, more extensive, more likely to be bilateral, recurrent and be less likely to recover than the optic neuritis seen in MS.

• #7 Neuromyelitis Optica – EyeWiki

  https://eyewiki.org/Neuromyelitis_Optica

  Many patients with or without treatment are left with severe residual visual loss with acuity 20/200 or worse. […] Permanent myelopathy and blindness can occur in NMOSD even after an initially monophasic course. […] Patients with NMOSD have a variable prognosis with many patients suffering high levels of disability. […] One study demonstrated that only 22% of patients had full recovery but 6% showed no recovery at all. […] Severe visual defects or motor impairment is present in about half of patients within 5 years of disease onset. […] Disease related mortality in NMOSD is most commonly due to neurogenic respiratory failure.

• #8 Neuromyelitis Optica (NMO): What It Is, Symptoms & Treatment

  https://my.clevelandclinic.org/health/diseases/9858-neuromyelitis-optica-nmo

  Myelitis is inflammation of your spinal cord. The symptoms of myelitis include muscle weakness or paralysis, spasticity, pain, incontinence, and sexual dysfunction. […] If NMO affects your brainstem, it can cause symptoms such as uncontrollable hiccups, nausea and vomiting, hearing loss, double vision, facial paralysis, dizziness, and nerve-based pain in your face. […] NMO attacks will cause vision problems, as they affect your optic nerves. That causes eye pain and disruptions in your vision. These usually get worse over a few days or weeks before peaking. […] When myelitis is severe, the pressure on your spinal cord can disrupt nerve signals to every part of your body at or below the affected area. That can cause muscle weakness, paralysis, and loss of the sense of touch below a certain point.

• #9 Neuromyelitis optica (NMO): Symptoms, treatment, and more

  https://www.medicalnewstoday.com/articles/170302

  Neuromyelitis optica (NMO), or Devics disease, is an inflammation of the sheath that protects the nerves in the eyes and the spinal cord. It can lead to weakness, eye pain, and temporary vision loss. […] Symptoms of NMO may vary and become more severe after multiple episodes, and confirming the triggers for these episodes requires further research. Resulting nerve damage can cause permanent damage and disability. […] People with NMO can develop optic neuritis, which causes eye pain and vision loss. They can also develop transverse myelitis (TM), which causes weakness or paralysis in the arms and legs, as well as a loss of bladder and bowel control. […] Symptoms may include: weakness in the arms and legs, pain in the arms and legs, increased sensitivity to cold and heat, tight, painful spasms in the arms and legs, bladder, bowel, and sexual difficulties.

• #10 Neuromyelitis Optica | Children’s Hospital of Philadelphia

  https://www.chop.edu/conditions-diseases/neuromyelitis-optica

  Neuromyelitis optica (NMO) is a rare inflammatory disease of the central nervous system affecting the optic nerves and spinal cord that can cause temporary or permanent blindness and paralysis. […] The most common presenting symptom of NMO is optic neuritis, in which patients experience pain inside one or both eyes particularly with eye movements, and loss of vision. Other symptoms may include: Weakness or paralysis in the legs or arms, Difficulty walking, Numbness or tingling, Painful spasms, Uncontrollable nausea, vomiting, or hiccups, Bladder or bowel control problems. […] In some attacks, dangerous complications can include unregulated changes in vital signs like heart rate and blood pressure, or even respiratory failure. An NMO attack is a medical emergency and needs to be treated promptly.

  https://www.apollohospitals.com/corporate/diseases-and-conditions/neuromyelitis-optica-nmo-disease-symptoms-causes-and-treatment/

  Neuromyelitis Optica disease causes episodic attacks, which means they come and go. These attacks can be severe and last anywhere between a few days and months. […] The symptoms are classified into optic neuritis, myelitis, and brain function disruption. […] The inflammation of the spinal cord is called myelitis. The inflammation results in swelling and increased pressure on the spinal cord or the nerves close to the spinal cord. Therefore, it may partially or entirely block the nerve signals that transmit through the affected nerve. The symptoms depend on the location of the inflammation in the spinal cord. The following are the symptoms of myelitis: Weakness in the muscle or paralysis affects the body parts below the affected spinal cord or further below the affected spinal nerve causing problems in using the arms and hands and trouble walking and standing. If myelitis is present in the cervical spinal cord, it can result in paralysis or muscle weakness that controls breathing. It can be life-threatening.

  Other symptoms of NMO may include: Hiccups. Nausea and vomiting. […] Symptoms may get better and then worse again. When they get worse, it’s known as a relapse. Relapses can happen after weeks, months or years. Over time, relapses can lead to total blindness or loss of feeling, known as paralysis.

• #13 Neuromyelitis Optica – Child Neurology Foundation

  https://www.childneurologyfoundation.org/disorder/neuromyelitis-optica/

  The breakdown of myelin can cause different symptoms in NMO depending on the part of the nervous system affected. […] Three specific areas of the brain and spine are commonly affected in NMO. When they are inflamed, symptoms appear. […] Transverse myelitis: This is inflammation in the spinal cord. It can cause: Weakness, numbness, cramping, or tingling of one part of the body. Tremor in one part of the body. Problems with urination or stooling (accidents). […] Optic neuritis: This is inflammation of the nerves that connect the eyes to the brain. It can cause: Loss of vision. Blank spots in the visual field. Blurry vision in one or both eyes. Loss of color vision (colors may look pale or washed out in one or both eyes). Pain, especially with eye movement. […] Area postrema syndrome: Inflammation in this area of the brain (the emetic reflex center at the floor of the fourth ventricle deep inside the brain) can cause: Nausea or vomiting. Long episodes of hiccupping.

• #14 Improving the Diagnosis of Neuromyelitis Optica Spectrum Disorder

  https://www.clinicalpainadvisor.com/cch/improving-the-diagnosis-of-neuromyelitis-optica-spectrum-disorder/

  Optic neuritis: A primary symptom of both MS and NMOSD, optic neuritis causes vision loss and pain with eye movements. Specific patterns of optic neuritis may help clinicians to distinguish among the 2 diseases. In patients with NMOSD, for example, optic neuritis is often longitudinally extensive, affecting more than half of the optic nerve. […] Area postrema syndrome (APS): Symptoms of intractable nausea, vomiting, and hiccups in APS are the presenting signs in approximately 12% of cases of NMOSD. […] Symptomatic brainstem syndrome: Brainstem lesions which may be evident on MRI are associated with a wide range of symptoms including hemiparesis, dysphagia, respiratory difficulties, oculomotor abnormalities, hearing loss, vertigo, and vestibular ataxia, as well as facial palsy, cranial nerve abnormalities, trigeminal neuralgia, and excessive yawning.

• #15 Neuromyelitis Optica – Child Neurology Foundation

  https://www.childneurologyfoundation.org/disorder/neuromyelitis-optica/

  The area postrema syndrome will often occur prior to the other symptoms associated with NMO. […] Generally, NMO symptoms will last for weeks. Sometimes symptoms go away entirely, and sometimes the damage is permanent. […] Some people with NMO will only have one attack. Others will have many. Attacks of NMO can cause serious problems with: Walking. Urination and stooling. Vision. […] In some rare cases, NMO can cause death. […] The brain and spinal cord cannot be repaired once damaged. Children with transverse myelitis (inflammation in the spinal cord) may need physical therapy or occupational therapy. This can improve walking and movement. […] NMO does not usually affect the way children think or process information. However, having a chronic illness can be stressful. Children may need counseling or psychological therapy to cope with the stress.

• #16 How Neuromyelitis Optica Progressed for Me

  https://www.webmd.com/eye-health/features/nmo-progression

  Joanna Robles, MD, first began having unusual symptoms in the summer of 2020. She had bouts of nausea and vomiting that she couldn’t explain. Eventually doctors diagnosed her with neuromyelitis optica (NMO), but the initial days were confusing. […] The primary way to diagnose the disease is with a blood test that looks for antibodies against a protein called aquaporin-4 (also called NMO-IgG). When the disease has been diagnosed, doctors treat any flare-ups and then try to prevent other flare-ups from happening. […] Most people who are diagnosed with NMO have either vision loss and eye pain — usually in one eye, but it can be both — or problems caused by inflammation of the spinal cord. That can include arm or leg weakness, numbness, and pain. […] Uncontrollable nausea, vomiting, or hiccups like Robles had are less common symptoms but very specific to this disease, says Aaron Miller, MD, medical director of the Corinne Goldsmith Dickinson Center for Multiple Sclerosis.

  Neuromyelitis optica spectrum disorder (NMOSD) is a rare autoimmune disease in which the immune system thinks the healthy tissues of the central nervous system are a threat and attacks them. Some of its symptoms are similar to the symptoms of multiple sclerosis, so it may be misdiagnosed as MS. […] NMOSD is a relapsing disease. This means that new inflammation in the nervous system produces relapses—also called flare-ups or attacks. The relapses can be weeks, months or years apart. Between relapses, people may experience some recovery. Relapses, which usually affect the optic nerves or spinal cord, can happen over hours or days. Some people have pain behind their eyes or notice that colors look faint or gray. They may also lose some strength and sensation in the arms, trunk and legs and have bladder or bowel control problems. Relapses require immediate medical attention to prevent worsening and minimize permanent disability.

  Signs and symptoms usually follow a relapsing and remitting course, but occasionally can be progressive (monophasic). Deficits can be temporary or permanent, the latter especially in the absence of treatment. […] Fatigue is a common symptom, with studies showing that as many as 77% of people with NMOSD have fatigue. Fatigue has been found to correlate with quality of life in people with NMOSD. […] The disease can be monophasic, i.e. a single episode with permanent remission afterwards. However, at least 85% of patients have a relapsing form of the disease with repeated attacks of transverse myelitis and/or optic neuritis. In patients with the monophasic form, the transverse myelitis and optic neuritis occur simultaneously or within days of each other. On the other hand, patients with the relapsing form are more likely to have weeks or months between the initial attacks, and to have better motor recovery after the initial transverse myelitis event. Relapses usually occur early, with about 55% of patients having a relapse in the first year and 90% in the first five years.

  Neuromyelitis optica spectrum disorder (NMOSD or NMO) is a rare inflammatory disease of the central nervous system (eye nerves, spinal cord, and brain). NMOSD is sometimes also called neuromyelitis optica or NMO. […] The chance of recurrence of disease activity after a first attack is greater than 90 percent. Attacks in NMOSD can be devastating. Outcomes vary widely among people, but the condition is still considered potentially devastating. Left untreated, early and severe disability is common. […] After the first attack, NMOSD follows an unpredictable path, and remission can vary. Attacks can last weeks to months. Symptoms may last off and on for years. They may also be temporary and can fully or partially resolve, most often after a course of treatment. However, this may not be the case for everyone. Reactions to treatment are highly unpredictable.

  When untreated, relapsing NMOSD relapses on average every 7 months. However, it can also relapse more or less often. Those who are on treatment may have a relapse about every 15 months. […] Generally, NMOSD symptoms begin suddenly. While symptoms may be temporary, each attack is damaging to the nerve fibers. Some people appear to recover fully after an attack, while others do not. […] When faced with a diagnosis of NMOSD, you will likely want to know if the disease will get better or worse over time. NMOSD affects everyone differently. The unpredictable course of disease makes it hard to know what will happen over time. New damage to the brain, eyes, and spinal cord during attacks can make the symptoms of NMOSD worse over time. Within 5 years, half of those diagnosed with NMOSD require a wheelchair.

  In children, NMOSD can cause confusion, seizures, or coma, according to the Mayo Clinic. […] About 90 percent of people with NMOSD have the relapsing form of the disease with periodic attacks and recovery in between, according to the Oregon Health Science University (OHSU) Brain Institute. But some people have whats known as the monophasic form of NMOSD, meaning they experience just one attack. […] An attack of NMOSD can last from days to weeks, according to NORD. The immediate goal of treatment for NMOSD is to stop the attack as quickly as possible. […] Periods of recovery between attacks can last for weeks, months, or even years, depending on individual differences and the treatments people receive, according to the OHSU Brain Institute. […] In anyone with NMOSD, the likelihood of future attacks without treatment is high, and there is no point in time when youre considered cured of the condition. That means youll need ongoing treatment to suppress your immune system and prevent future attacks, according to the National Multiple Sclerosis Society.

  https://www.massgeneral.org/neurology/treatments-and-services/about-neuromyelitis-optica-nmosd

  Neuromyelitis optica spectrum disorder (NMOSD) is a rare autoimmune disease of the central nervous system in which a persons immune system invades the optic nerves and spinal cord leading to vision loss and paralysis. […] Unlike in MS, the disease does not progress between attacks, but the attacks themselves are generally more severe than in those patients with MS. Generally characterized by an unpredictable and relapsing course, NMO causes increasing disability with each attack. […] When NMOSD attacks, patients may experience optic neuritis inflammation of the optic nerves that causes eye pain and reduced vision in one or both eyes and/or transverse myelitis inflammation of a segment of the spinal cord, causing sensory changes, potential loss of bladder and bowel control, numbness, tingling and possible paralysis.

  Most people experience recurring NMO attacks (relapsing) while some people may get a one-time attack (monophasic). Early diagnosis and timely treatment with immunosuppressive drugs improve the outlook. Medicines and therapies can ease the symptoms and people with NMO may live for many years. People who have monophasic NMO have a better prognosis than those with relapsing NMO.

  https://www.saintlukeskc.org/health-library/neuromyelitis-optica

  Neuromyelitis optica (NMO) is a rare autoimmune disease that affects the central nervous system. […] NMO mainly affects the spinal cord and the optic nerves—the nerves that carry signals from the eyes to the brain. As a result, the disease can cause paralysis and blindness. […] The onset of NMO varies from childhood to adulthood, with two peaks, one in childhood and the other in adults in their 40s. Women are more often affected than men. […] There are 2 types of NMO: Relapsing form, which has periodic flare-ups, with some recovery in between. This is the more common kind. Women are far more likely to have this form than men. […] Monophasic form, which involves a single attack that lasts a month or 2 then may be free from attacks for several years. Men and women get this type equally.

• #25 Frequently Asked Questions About Neuromyelitis Opticamail2

  https://guthyjacksonfoundation.org/nmo-faqs/

  NMO symptoms can vary from person to person and may resemble MS symptoms in many ways. NMO is most commonly characterized by inflammation of the spinal cord and/or optic nerves, causing any one or more of the following symptoms: Rapid onset of eye pain or loss of vision (optic neuritis). Limb weakness, numbness, or partial paralysis (transverse myelitis). Shooting pain or tingling in the neck, back or abdomen. Loss of bowel and bladder control. Prolonged nausea, vomiting or hiccups. Sometimes these symptoms are temporary, and resolve on their own. In any case, it is important to discuss these symptoms with your doctor to help consider NMO in your diagnosis. […] The time interval between relapses or attacks can range from days, weeks, months or even years apart. Some cases have been known to have attacks 15 years apart. In some patients there is only one episode (no relapses), but such cases are relatively uncommon. Relapsing NMO is most common and identified by recurrent attacks separated by months or years. Attacks are usually followed by partial or complete recovery during periods of remission. This relapsing form of NMO appears to affect women 4 times more commonly than men. Unfortunately, in some severe cases of relapsing NMO, recovery may not occur following a relapse, causing permanent disability. Monophasic NMO is less common and is usually characterized by a single, severe attack over a short period of time (days or weeks). As a rule, relapses do not occur in monophasic NMO. This form of NMO typically affects optic nerve(s) and the spinal cord. Interestingly, women and men tend to be equally affected by this form of NMO. When a patient is first diagnosed with NMO, it is unclear whether they will experience a monophasic or relapsing course. In either scenario, accurate and rapid diagnosis of relapses is a key to minimizing severity and promoting recovery.

• #26 NMO – International Pediatric Multiple Sclerosis Study Group

  https://ipmssg.org/professionals/other-demyelinating-diseases/nmo/

  Neuromyelitis optica (NMO), also known as Devic’s disease, is an autoimmune disorder in which immune system cells and antibodies mistakenly attack and destroy myelin cells in the optic nerves and the spinal cord. The damage to the optic nerves produces swelling and inflammation that cause pain and loss of vision; the damage to the spinal cord causes weakness or paralysis in the legs or arms, loss of sensation, and problems with bladder and bowel function. […] NMO occurs in two different forms: a single attack extending over a month or two, or a more common relapsing form in which the person experiences multiple attacks. […] Children with NMO usually present with “attacks” of new neurological symptoms appearing within a few hours or days. Children with NMO can have attacks with symptoms of blurred vision, or loss of vision in one eye or both eyes. Other symptoms are weakness or numbness of the arms or legs. Some children experience confusion or extreme lethargy at their attacks. Other possible symptoms including vomiting, fever or seizures.

  Neuromyelitis optica spectrum disorder (NMOSD), also known as Devics disease, is a rare and debilitating autoimmune disease caused by inflammation in the central nervous system (the optic nerve, brain stem and spinal cord). If left untreated, this inflammation can cause repeat attacks and permanent disability, such as blindness and paralysis. […] Within one year, 60% of those with NMOSD will have repeat attacks with no NMOSD treatment. […] After five years, four out of 10 of those with NMOSD may be legally blind in at least one eye, and two out of 10 may require a walker. […] Of those with optic neuritis (or vision challenges), 67% had partial or no recovery following an NMOSD attack. […] A single attack can cause disability. […] Attacks are usually more severe and can result in permanent disability. […] Hiccups, nausea and vomiting are more common symptoms. […] People with NMOSD can experience a wide range of seemingly unconnected symptoms. If you are experiencing any new or worsening symptoms, contact your doctor immediately as it may signal a new attack.

• #28 Neuromyelitis optica spectrum disorder – Wikipedia

  Approximately 20% of patients with monophasic NMO have permanent visual loss, and 30% have permanent paralysis in one or both legs. Among patients with relapsing NMO, 50% have blindness or paralysis within five years. In some patients (33% in one study), transverse myelitis in the cervical spinal cord resulted in respiratory failure and subsequent death. However, the spectrum of NMO has widened, due to improved diagnostic criteria; and the options for treatment have improved. As a result, researchers believe these estimates will be lowered.

  Neuromyelitis optica spectrum disorder (NMOSD) is a severe demyelinating diseases, which in seropositive cases, is caused by an autoantibody to the aquaporin-4 (AQP4) water channel. The classic presentation of NMOSD is with the triad of bilateral optic neuritis, longitudinally extensive myelitis, and positive anti-AQP4 antibody, although a far wider range of manifestations are now recognized as part of NMOSD. […] NMOSD is usually a relapsing condition, characterized by bilateral optic neuritis (usually bilateral, but can be unilateral) and myelitis resulting in blindness and myelopathy (paraplegia often with atypical symptoms such as pain and pruritus) respectively. Although the two classically present concurrently, it is not uncommon for one to precede the other by up to several weeks, or to occur each as standalone clinical presentations. […] Patients with a relapsing course have a poorer prognosis: blind in one or both eyes: monophasic 22% vs relapsing 60%; monoplegia or paraplegia: monophasic 31% vs relapsing 52%.

  These symptoms often come as attacks that can last for days or months, then lessen or stop. Attacks, or relapses, may come months or even years apart. They can leave permanent damage and disability and can lead to other issues. […] Over 40% of people with neuromyelitis optica can become legally blind in at least one eye within five years of the condition first appearing. […] Treatment is most effective when it begins as early as possible. Early intervention can slow or stop progression of the disease and prevent disabilities. […] NMO is not a curable condition. But early intervention and treatment can stop progression of the disease, prevent disability and prevent relapses. The goal is to maintain or improve your quality of life. […] The life expectancy of patients with NMO will vary a great deal from person to person. Without treatment, it often leads to worsening disability and can shorten life expectancy. But with effective treatment, life expectancy for a patient with NMO is the same as a person who does not have the condition, and progression of disability can often be slowed or stopped, leading to greater quality of life.

  NMO Disease Life Expectancy is affected by early diagnosis, treatment, disease progression and relapse frequency, and demographic/genetic factors. […] Effective management of NMO through immunosuppressive therapies, lifestyle modifications, and support systems significantly improves life expectancy for those with the condition. […] Timely diagnosis and treatment of NMO are essential for reducing the severity and distinguishing it from multiple sclerosis (MS), as well as for reducing the mortality rate. […] The disease progression and frequency of relapses influence the life expectancy of NMO patients. It has been observed that a higher frequency of attacks is linked to a reduced life expectancy. […] About 22% of individuals diagnosed with the dominant AQP4-positive NMOSD subtype need a mobility aid within five years of the disease onset.

  https://www.myvaccinelawyer.com/vaccine-injury-lawyer/resources/vaccine/injury/neuromyelitis-optica/life-expectancy/

  Late-onset, which occurs in patients over 50 years of age, is associated with increased motor disability and potentially higher mortality rates. […] NMO generally has a more severe disease course compared to MS. […] The average life expectancy for patients with NMO is approximately 5 years following the initial attack if left untreated; however, with treatment, outcomes are substantially improved. […] Proper management of NMO, including therapies, lifestyle changes, and support, improves patient health and life expectancy. […] Immunosuppressive therapies help reduce the risk of recurrence and induce remission in NMO patients, ultimately impacting disability and death.

  Considered a hallmark of NMOSD, longitudinally extensive transverse myelitis (LETM) is defined as myelitis spanning at least 3 spinal segments. Neurologists should be aware that short-segment myelitis is also common in NMOSD; neglecting to consider this is associated with delay in diagnosis and treatment. […] Relapse rates in women with NMOSD do not change during pregnancy in contrast to women with MS, who have a reduced relapse rate during pregnancy; relapse risk increases during the first 3 months postpartum in both women with NMOSD and MS, however. […] The most common presenting features of NMOSD in children include visual, motor, and constitutional symptoms (ie, vomiting, fever, seizures). A single study reported a mean annualized relapse rate (ARR) of 0.6 in pediatric-onset NMOSD compared with 1.0 in adult-onset NMOSD; time to disability is longer in patients with pediatric-onset, largely explained by the severity of a first episode of myelitis in adults.

NMO mainly affects the spinal cord and the optic nerves—the nerves that carry signals from the eyes to the brain. As a result, the disease can cause paralysis and blindness. […] The onset of NMO varies from childhood to adulthood, with two peaks, one in childhood and the other in adults in their 40s. Women are more often affected than men. […] The conditions do have some similar symptoms, however they are usually more severe in NMO. Vision problems with multiple sclerosis usually affect 1 eye at a time, while NMO may affect both eyes at the same time. […] These are possible symptoms of NMO: Pain in the eyes, Loss of vision, Weakness or numbness in the arms and legs, Paralysis of the arms and legs, Difficulty controlling the bladder or bowels, Uncontrollable vomiting and hiccups.

  Neuromyelitis optica spectrum disorder (NMOSD) is a rare autoimmune disease that affects the central nervous system. […] NMOSD mainly affects the spinal cord and the optic nerves the nerves that carry signals from the eyes to the brain. As a result, the disease can cause paralysis and blindness. It can rarely affect the brainstem (base of the brain) causing intractable vomiting, hiccups, sleep attacks, and other rare symptoms. […] Unlike MS, the attacks of NMOSD are usually more severe. Vision problems with MS usually affect one eye at a time and result in mild visual impairment while NMOSD may affect both eyes at the same time and may cause severe visual loss. Likewise, spinal attacks in NMOSD can lead to severe paralysis and painful tonic spasms much more severe than what is seen in MS.

• #36 Neuromyelitis Optica (NMO) vs. MS: How These Conditions Compare

  https://www.healthline.com/health/neuromyelitis-optica

  NMO is a rare disease that damages the optic nerve, brain stem, and the spinal cord. […] It leads to optic neuritis, which causes pain in the eyes and loss of vision. Other symptoms can include muscle weakness, numbness, and bladder control problems. […] NMO attacks, on the other hand, can be severe and lead to health problems that cant be reversed. Early and aggressive treatment is important in reducing the harm caused by NMO. […] NMO may strike once and last for a month or two. […] NMO doesn’t have a progressive course like MS can. The symptoms in NMO are due only to attacks.

• #38 Diagnosing and Managing Neuromyelitis Optica

  https://www.uspharmacist.com/article/diagnosing-and-managing-neuromyelitis-optica

  Neuromyelitis optica (NMO) is an autoimmune disorder of the central nervous system that targets the optic nerves and the spinal cord, resulting in optic neuritis and myelitis, respectively. Symptoms may consist of pain, bowel and bladder dysfunction, fatigue, cognitive impairment, and psychiatric disturbances. NMO/NMOSD results in recurrent attacks that can lead to severe disability, blindness, and paralysis. Symptoms can be grouped as visual (blindness), motor (spasms/spasticity/paralysis) and/or sensory dysfunction (neuropathic pain, bowel and bladder dysfunction, and sexual dysfunction), and psychiatric or cognitive impairment. […] Pain severely impacts quality of life, with pain having a prevalence of over 80% in NMO/NMOSD. The pain syndrome experienced can be neuropathic, nociceptive, and/or mixed pain syndromes. NMO/NMOSD-related pain can be chronic in nature as the disease progresses or can develop during acute relapses. Fatigue in NMO/NMOSD affects quality of life, depression, sleep quality, and pain intensity, which worsens with high fatigue severity. Lower urinary tract symptoms occur in about 80% of NMO/NMOSD cases in which they may experience frequency, urgent and stress incontinence, nocturia, urinary retention, and incomplete evacuation. The most common lower urinary tract symptom is urinary retention.

• #40 Neuromyelitis Optica: Symptoms, Causes, Treatment, and More

  https://www.webmd.com/brain/neuromyelitis-optica

  NMO happens because your body’s immune system attacks healthy cells in your central nervous system (your brain and your spinal cord). […] These attacks can happen over days or weeks — this is called monophasic NMO. Or you may go a long time between attacks, even months or years. This is called relapsing NMO. With relapsing NMO, symptoms go away but can come back and get worse over time. […] The signs of NMO fall into two categories. See your doctor if you have any of these symptoms: […] Optic neuritis: inflammation of the optic nerve (this carries information from your eye to your brain). You might feel sudden pain inside your eye. That can be followed by problems like not seeing clearly or even blindness. It usually happens only in one eye, but it can happen in both. […] Transverse myelitis: inflammation of the spinal cord. This can cause problems with your arms and legs, including pain, weakness, numbness, or paralysis. It also can lead to loss of control of your bladder and bowel. You could have nausea, vomiting, hiccups, a stiff neck, or a headache. […] Children who have NMO may seem confused, have seizures, or fall into a coma.

  https://www.mayoclinic.org/diseases-conditions/neuromyelitis-optica/diagnosis-treatment/drc-20375655

  Diagnosing neuromyelitis optica involves a physical exam and tests. […] Criteria to diagnose neuromyelitis optica spectrum disorder (NMOSD) were proposed in 2015 by the International Panel for NMO Diagnosis. […] The spinal fluid might show a very high level of white blood cells during NMO episodes. This is greater than the level usually seen in MS, although this symptom doesn’t always happen. […] Neuromyelitis optica can’t be cured. But treatment can sometimes lead to a long-term period with no symptoms, known as remission. NMO treatment involves therapies to reverse recent symptoms and prevent future attacks. […] In the early stage of an NMO attack, a healthcare professional might give a corticosteroid medicine such as methylprednisolone (Solu-Medrol). […] Plasma exchange is often recommended as the first or second treatment, usually in addition to steroid therapy.

  Your healthcare professional might recommend that you take a lower dose of corticosteroids over time to prevent future NMO attacks and relapses. […] Monoclonal antibodies have been shown in clinical trials to be effective in reducing the risk of NMO relapses. […] Intravenous immunoglobulins, also known as antibodies, may decrease the relapse rate of NMO.

• #43 Neuromyelitis Optica Spectrum Disorders

  https://practicalneurology.com/articles/2019-feb/neuromyelitis-optica-spectrum-disorders

  Acute exacerbations of NMOSD are initially treated with IVMP, typically 1 g daily for 3 to 5 days. Some clinicians include an oral prednisone taper starting at up to 1 mg per kg per day (usually 15-30 mg/day) and decreasing gradually over several weeks depending on individual factors such as timing of disease modifying therapy, patient comorbidities, and tolerance of oral glucocorticoids. Long-term oral glucocorticoids are associated with significant toxicity and are often avoided in favor of steroid-sparing immunotherapy. […] Given the available data, we prefer rituximab (RTX) for most patients with NMOSD. If there are contraindications to RTX, we typically use mycophenolate mofetil (MMF).

• #44 Diagnosing and Managing Neuromyelitis Optica

  https://www.uspharmacist.com/article/diagnosing-and-managing-neuromyelitis-optica

  NMOSD attacks can be characterized as unpredictable, severe, and recurrent. The most prevalent ones are transverse myelitis, optic neuritis, and area postrema syndrome inflammation or lesions of brain stem that lead to nausea, uncontrollable vomiting, hiccups, or a combination of these symptoms. These are neurologic worsening symptoms that reflect focal or multifocal CNS inflammation that develops acutely or subacutely, in the absence of fever or infection, with a duration of at least 24 hours occurring more than 30 days after the previous attack. […] In contrast to those of MS, acute attacks of NMO/NMOSD often result in permanent damage from relapses and cumulative disability. Therefore, aggressive, high dosages of steroids for acute management are widely accepted by most expert panel recommendations and considered the treatment mainstay. Typical dosing includes high-dose IV methylprednisolone 1,000 mg given daily for 3 to 5 days.

  Neuromyelitis Optica NMO is also known as Devics disease or neuromyelitis optica spectrum disorder (NMOSD. […] Up to 30% of patients, however, have residual visual and neuromuscular disabilities after the initial attack, which can worsen with relapses. […] The symptoms of NMO arise either out of optic neuritis and/or transverse myelitis, depending on which nerves are affected. […] Symptoms include: Pain inside the eye, Blurry vision or loss of vision. […] Symptoms may include any of the following: Pain, weakness, and/or numbness in arms and legs, Paralysis of arms and legs, Loss of control over bladder and/or bowel functions, Uncontrollable hiccups, nausea, and vomiting, Stiff neck and headache. […] Currently, there is no cure for NMO, but treatments can reduce the frequency and severity of attacks and alleviate symptoms. […] Symptoms after an NMO attack are generally more severe than those after multiple sclerosis (MS) attack, though, unlike MS, NMO rarely has a progressive stage between episodes. […] NMO episodes can have debilitating and irreversible effects, and can also lower life expectancy.

• #54 Updated diagnostic criteria for neuromyelitis optica spectrum disorders (NMOSD)

  https://blog.swedish.org/swedish-blog/updated-diagnostic-criteria-for-neuromyelitis-optica-spectrum-disorders-nmosd

  Neuromyelitis optica (NMO) is a neuroinflammatory disorder characterized by optic neuritis and extensive myelitis. Like multiple sclerosis (MS), it can have a relapsing remitting disease course. Some of the NMO patients tend to run a more aggressive disease course. Most patients with NMO have Ig G antibodies to the aquaporin-4 water channel (AQP4). […] Patient with clinical presentation with at least one core syndrome should be evaluated for possible NMOSD. Some of these syndromes are similar to MS, such as optic neuritis and acute myelitis. Other typical syndromes, such as area postrema syndrome (intractable nausea and vomiting, or hiccups), an acute brainstem syndrome or symptomatic narcolepsy should also be evaluated carefully. […] These valuable criteria allow us to make a correct diagnosis of NMOSD early in the disease course.
