It is also known as neuromyelitis optica (NMO) or Devic's disease. Some of its symptoms are similar to the symptoms of multiple sclerosis, so it may be misdiagnosed as such.
Sjogren's syndrome is an autoimmune disease that can mimic some of the symptoms of MS such as fatigue and joint pain.
The mortality associated with NMOSD is high and variable. When it is not identified or when it remains untreated, about 30% of patients die within the first 5 years of the disease.
Devic's disease, also known as neuromyelitis optica (NMO) spectrum disorder, is a rare neuro-immune disorder that affects your eyes and your spinal cord. It may also attack the brain.
There are three main types of MS - relapsing, primary progressive and secondary progressive. MS affects everyone differently.
Establishing a causal relationship between the virus and the disease has been difficult because EBV infects approximately 95% of adults, MS is a relatively rare disease, and the onset of MS symptoms begins about 10 years after EBV infection.
It is also known as neuromyelitis optica (NMO) or Devic's disease. Some of its symptoms are similar to the symptoms of multiple sclerosis, so it may be misdiagnosed as such.
Symptoms are generally more severe for the NMO spectrum disorder attack than the MS attack. A specific blood marker that is found in people with NMO spectrum disorder is not found in people with MS. In MS, individual episodes are usually mild. Over time, they may or may not cause progressive disability.
Causes. NMO is an autoimmune condition. This means the body's immune system reacts abnormally and attacks healthy tissues, causing the symptoms of NMO. NMO is usually not inherited, but some people with NMO may have a history of autoimmune disorders in the family and may have another autoimmune condition themselves.
The cause of multiple sclerosis is unknown. It's considered an immune mediated disease in which the body's immune system attacks its own tissues. In the case of MS , this immune system malfunction destroys the fatty substance that coats and protects nerve fibers in the brain and spinal cord (myelin).
Some of the most common mimics include migraine and chronic cerebrovascular disease, according to Dr Schiess. Vasculitic autoimmune diseases such as systemic lupus erythematosus (SLE) and Sjögren's syndrome can also result in white matter abnormalities on MRI.
Although MRI is a very useful diagnostic tool, a normal MRI of the brain does not rule out the possibility of MS. About 5 percent of people who are confirmed to have MS do not initially have brain lesions evidenced by MRI.
Misdiagnosing MS can have harmful effects. A person may be started on an unnecessary treatment course with possibly detrimental side effects. That's why it's so important to work with your healthcare team to accurately diagnose MS and rule out every other possible reason for your symptoms.
Can I have multiple sclerosis for years and not know it? Yes. MS can go undetected for years. Research has suggested that many patients experience MS-related symptoms and signs several years before receiving a definite diagnosis of the disease.
An MRI scan can detect MS activity early on , sometimes before an individual experiences any worsening symptoms.
your genes – MS isn't directly inherited, but people who are related to someone with the condition are more likely to develop it; the chance of a sibling or child of someone with MS also developing it is estimated to be around 2 to 3 in 100.
In MS, immune cells attack the myelin, which leads to the symptoms of MS. In NMO, the immune system only attacks the spinal cord and brain throughout the duration of the disease. In contrast, MS can affect the brain, spinal cord, and optic nerve.
MS is not directly inherited from parent to child. There's no single gene that causes it. Over 200 genes might affect your chances of getting MS.
Lifetime risk of MS by relationship to someone with MS:
Parent - 1 in 67. Child - 1 in 48. Relatives that were less closely related had a lower risk. The lifetime risk in the general population is about 1 in 330.
What is the average age of MS diagnosis? An MS diagnosis can come in childhood thorugh to age 50 and beyond. However MS is most commonly diagnosed between the ages of 20 and 40, and is approximately three times more common in women than men.
Segal says. “Some people with COVID-19 infections experience neurological symptoms that may be secondary to this response. MS is caused by an abnormal immune response targeting the central nervous system. This raised concerns that COVID-19 could exacerbate MS.”
COVID-19 risk for people with MS
However certain factors, including some disabilities that may result from your MS, have been shown to increase the risk of a severe case of COVID-19: Progressive MS. Older age.
Clostridium perfringens and epsilon toxin may explain many of these mysteries.” An environmental trigger is required for MS to occur in a genetically susceptible individual, and the abundance of epsilon toxin-producing Clostridium perfringens in people with MS suggests it could be the culprit.
