Neuromyelitis optica NMO, sometimes known as ‘Devic’s disease’ is a rare autoimmune disorder of the central nervous system CNS where antibodies can damage the spinal cord and/or optic nerves during attacks.
17.03.2015 · MRI characteristics of neuromyelitis optica spectrum disorder. An international update. MRI lesions characteristic of neuromyelitis optica spectrum disorder. The actual utility of lesion probability maps to distinguish NMO and MS is limited by an unclear definition of some traditional criteria for MS-suggestive findings. Multiple Sclerosis and Neuromyelitis Optica. Until recently, Neuromyelitis Optica was thought to be a type of Multiple Sclerosis. However, recent discoveries indicate that NMO and MS are distinct diseases. Traditionally spinal cord lesions seen in NMO are longer than MS but this is not always the case.

It is important to distinguish NMO from MS as the treatment not only is different but treating a patient with NMO with MS-specific therapies e.g. beta-interferon or natalizumab can actually lead to its exacerbation 5.
Although NMO spectrum disorders have very similar clinical and radiologic characteristics to MS, the diseases are treated very differently. A majority of NMO patients, typically women, are initially misdiagnosed with MS. While NMO is treated by immunosuppressant therapy, MS is treated by immunomodulation therapy, which may worsen NMO. MS abbreviations NMO Neuromyelitis Optica Also known as Devic’s syndrome, neuromyelitis optica is a form of inflammatory demyelinating disease, which resembles, or mimics, MS in several ways. Despite Similarities, NMO and MS Take Different Courses, Require Different Treatments. November 26, 2010. Dear Mayo Clinic: What can you tell me about neuromyelitis optica? Distinguishing between NMO and RRMS is important in guiding treatment, but biomarkers of NMO and MS can be absent early in the disease process.

Multippel sklerose MS er en kronisk betennelsesykdom i sentralnervesystemet hjernen og ryggmargen.MS gir ulike symptomer, avhengig av hvilke områder som påvirkes av betennelsen.De vanligste symptomene ved MS er utmattelse MS-fatigue, tremor, vannlatingsproblemer, kognitive forstyrrelser, gangvansker og ustøhet, redusert syn og synsforstyrrelser, muskelsvakhet, endret.

08.02.2020 · Neuromyelitis optica NMO has long been considered as a variant of multiple sclerosis MS rather than a distinct disease. This concept changed with the discovery of serum antibodies Ab against aquaporin-4 AQP4, which unequivocally differentiate NMO from MS. Patients who test positive for AQP4-Abs and present with optic neuritis ON and transverse myelitis TM are diagnosed with NMO. Neuromyelitis optica NMO, also known as Devic's disease, is a rare condition that affects the spinal cord and the nerves of the eyes optic nerves. It can cause a wide range of symptoms, such as weakness, blindness, nerve pain and muscle spasms. 08.02.2020 · Neuromyelitis optica NMO has been described as a disease clinically characterised by severe optic neuritis ON and transverse myelitis TM. Other features of NMO include female preponderance, longitudinally extensive spinal cord lesions >3 vertebral segments, and absence of oligoclonal IgG bands. In spite of these differences from multiple sclerosis MS, the relationship between NMO.
The Anti-NMO antibody strangely enough. The problem is only about ?? 78% of people with NMO have this antibody. So when the test is positive it is the real deal, but when it is negative you are not as sure. NMO is far, far more rare than MS and also tends to be far more serious and disabling, so we are hoping for MS, I would presume.

In the past, NMO was considered to be a severe variant of multiple sclerosis MS because both can cause attacks of optic neuritis and myelitis. Recent discoveries, however, suggest it is a separate disease.
It is now clear that NMO-IgG anti-AQP4 plays a direct role in the pathogenesis of NMOSD. In MS lesions, the distribution of AQP4 protein expression depends upon the stage of demyelination, while in NMOSD lesions, there is a loss of AQP4 expression that is unrelated to the stage of demyelination. Neuromyelitis optica NMO is a heterogeneous condition consisting of the inflammation and demyelination of the optic nerve optic neuritis and the spinal cord.It can be monophasic or recurrent. Currently at least three different kinds are proposed based on the presence of autoantibodies thought to produce the disease: anti-AQP4, anti-MOG and anti-NF. Not that long ago neuromyelitis optica was called Devics MS but it was split because it seems to have a different pathology and responds to MS drugs differently. It also more commonly presents itself East Asia. One of the features of NMO in some people is the production of an antibody to Aquaporin 4 a water channel on astrocytes.
Background: The authors previously proposed diagnostic criteria for neuromyelitis optica NMO that facilitate its distinction from prototypic multiple sclerosis MS. However, some patients with otherwise typical NMO have additional symptoms not attributable to optic nerve or spinal cord inflammation or have MS-like brain MRI lesions. I have neuromyelitis optica NMO. NMO was once considered a subset of MS. NMO has very similar symptoms to MS so unfortunately a lot of NMO patients are misdiagnosed as having MS when really they do not. NMO and MS although similar symptoms have very different treatment plans and different medications. Thus, if MS pat. The NMO antibody has high specificity and variable sensitivity depending on population being studied. Its discovery has not only aided in distinguishing NMO from MS but also helped to define the features that characterize NMO. On the other hand, MOG protein has been more variably associated with MS.
