What is the diagnosis of neuromyelitis optica?
A diagnosis of neuromyelitis optica spectrum disorder (NMOSD) is based upon a clinical examination looking for the presence of characteristic symptoms and imaging studies ( MRI) of the brain, spinal cord, and eyes. [4] Additional testing may include a blood test looking for a specific type of antibody and a spinal tap to collect a small amount of fluid that surrounds the brain and spinal cord to look for white blood cells. [3]

Why does NMO happen?
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.

Some people with NMO also have other autoimmune diseases such as Sjogren’s Syndrome or Systemic Lupus Erythematosus (SLE).
What is the cause of NMO?
The cause of NMO in the majority of cases is due to a specific attack on the aquaporin-4 (AQP4) water channel located within the optic nerves and spinal cord. Aquaporins (AQPs) are proteins that transport water across cell membranes. More than 70% of NMO and NMOSD patients test positive for an antibody biomarker in the blood called ...
What is the role of astrocytes in demyelination?
Astrocytes are supportive cells in the brain, spinal cord and optic nerves, and damage to astrocytes is believed to lead to demyelination. In cases associated with anti-MOG antibodies, it is considered that anti-MOG antibodies may trigger an attack on the myelin sheath resulting in demyelination.

What is NMO in biology?
NMO is considered to be an autoimmune disease (where the immune system reacts against healthy tissue as if it was a threat). In the majority of cases of NMO, the immune system recognizes the AQP4 water channel as foreign and develops antibodies (NMO-IgG or anti-AQP4 antibody) to attack AQP4 on the surface of astrocytes, ...
What is the biomarker for NMO?
More than 70% of NMO and NMOSD patients test positive for an antibody biomarker in the blood called the NMO-IgG or anti-AQP4 antibody. In people with NMO who test negative for anti-AQP4 antibodies, up to a third may be positive for auto-antibodies directed against a component of myelin called myelin oligodendrocyte glycoprotein (MOG).

Who first reported spinal cord and optic nerve disorders?
Sir Thomas Clifford Allbutt. First reports on an association of spinal cord and optic nerve disorders date back to the late 18th and early 19th century. However, only an 1870 report by Sir Thomas Clifford Allbutt created sustained interest of neurologists and ophthalmologists in this rare syndrome.
How many people with NMO have permanent paralysis?
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 paralysis or blindness 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.
What is NMOSD in medical terms?
The term NMOSD (neuromyelitis optica spectrum disorders) has been designed to allow incorporation of cases associated with non- AQP4 biomarkers. Therefore, it includes all the clinical variants due to anti-AQP4 plus other non-related but clinically similar syndromes like anti-MOG associated encephalomyelitis. Some cases with MOG + and AQP4 + antibodies have been found.
What is NMOSD?
Neuromyelitis optica spectrum disorders ( NMOSD) is an etiologically heterogeneous syndrome predominantly characterized by acute inflammation of the optic nerve ( optic neuritis, ON) and the spinal cord ( myelitis ). Episodes of ON and myelitis can be simultaneous or successive. A relapsing disease course is common, especially in untreated patients. In more than 80% of cases, NMO is caused by immunoglobulin G autoantibodies to aquaporin 4 ( anti-AQP4 ), the most abundant water channel protein in the central nervous system. A subset of anti-AQP4-negative cases is associated with antibodies to myelin oligodendrocyte glycoprotein ( anti-MOG ). Rarely, NMO may occur in the context of other autoimmune diseases (e.g. connective tissue disorders, paraneoplastic syndromes) or infectious diseases. In some cases, the etiology remains unknown ( idiopathic NMO).
What causes NMOSD?
Causes. NMOSD is caused by an autoimmune attack on the nervous system. In more than 80% of cases, IgG autoantibodies against aquaporin-4 ( anti-AQP4+) are the cause, and in 10–40% of the remaining cases, IgG antibodies against MOG are the cause.
How does NMO differ from MS?
NMO differs from MS in that it usually has more severe sequelae after an acute episode than standard MS , MS infrequently presents as transverse myelitis, and oligoclonal bands in the CSF , as well as white matter lesions on brain MRI, are uncommon in NMO, but occur in over 90% of MS patients.
What is the most common manifestation of a disease?
The most common initial manifestation of the disease is inflammation of the spinal cord (myelitis). Myelitis causes spinal cord dysfunction, which can cause muscle weakness, reduced sensation, or loss of bladder and bowel control as well as erectile dysfunction.

Types of NMO treatments include: Intravenous corticosteroids: These manage an ongoing attack. Plasma exchange: Healthcare professionals typically recommend this if corticosteroids aren’t enough to manage an attack. It involves filtering blood to remove certain antibodies linked to NMO symptoms.
What is the best medicine for NMO?
The Food and Drug Administration (FDA) has approved three drugs for NMO in anti-AQP4 positive people: Healthcare professionals may also use several other immunosuppressants, including rituximab (Rituxan) and mycophenolate mofetil (CellCept), off-label to prevent NMO attacks.
How long does a monophasic NMO last?
There are two types of NMO: Monophasic NMO: This single acute attack of NMO lasts for about 1 month and does not recur within 3 years. It occurs very rarely. In fact, a 2020 study that followed people with NMO for a longer period of time suggests the condition might not actually exist.
What is the life expectancy of a person with NMO?
The life expectancy of a person with NMO varies widely. Past studies have suggested that the natural 5-year mortality rate for NMO is about 22–30%, according to a 2021 research review. More recent research suggests that with treatment the rate declines to 3–7%. Mortality depends on several factors, including:
