diagnosis

When I was misdiagnosed with multiple sclerosis (MS), and five years later, properly diagnosed with neuromyelitis optica (NMO), I was told that a hallmark symptom of each disease was optic neuritis. This occurs when the immune system mistakenly attacks the optic nerve, causing inflammation, which can lead to…

Fourteen years ago, when I was in the process of being diagnosed, I suffered a major neuromyelitis optica (NMO) attack on my spinal cord. The resulting transverse myelitis robbed me of the feeling in my arms and hands. As an artist, this was utterly devastating. My manual dexterity…

A system that stages neuromyelitis optica spectrum disorder (NMOSD) based on damage to astrocytes — the specific brain cells that are attacked in NMOSD — was recently developed by a team of researchers in Japan. While more work is needed, the system identifies four stages, largely based on astrocytopathy…

Examining the thickness of certain retinal layers in the eye, along with structural changes in the eyes’ blood vessels, can help differentiate neuromyelitis optica spectrum disorder (NMOSD) from multiple sclerosis (MS), a study found. Overall, two particular retinal layers — the peripapillary retinal nerve fiber layer…

I still remember the feeling of despair I had while sitting on a cool stretcher in the neurologist’s office, after hearing devastating news about my health. The neurologist admitted that he had no idea what I had, but he assured me it was a severe condition. I wondered why after…

A vision test using a 2.5%-contrast letter chart is more effective than the conventional 100%-contrast chart at detecting previous episodes of optic neuritis, an eye condition that is often the first symptom of neuromyelitis optica spectrum disorder (NMOSD), a study shows. Results, drawn from responses in unaffected people and those…

When I was being diagnosed, my initial MRI revealed that I had long lesions over several sections of my spinal cord. While I knew nothing about the disease I was about to be diagnosed with, I understood that any damage to my spinal cord was bad news. It meant I…

Using a live cell-based assay to test for the presence of aquaporin-4 antibodies (AQP4-IgG) can accurately identify people who have neuromyelitis optica spectrum disorder (NMOSD), new research suggests. Scientists said the cell-based assay was “a highly specific diagnostic biomarker of NMOSD and did not yield false positive results.” These findings…

Because there is little information available about certain diseases, many people may be misdiagnosed or undiagnosed. People with rare diseases are at a disadvantage compared with people with well-known medical conditions. Not only do people with rare diseases have limited information, but also their treatment is often not as…
