Neuromyelitis optica
An attack orrelapse of NMO results in the nervous system becoming inflamed. The inflammation usually occurs in the optic nerve and spinal cord, and causes new symptoms or the recurrence of previous symptoms.
Less common symptoms of NMO can include unexplained nausea and vomiting, unexplained itching and tonic spasms (painful muscle contractions). In someone with known NMO, these symptoms may signify a new relapse.
NMO symptoms can range from mild to severe. In some cases, there may only be one attack of optic neuritis or transverse myelitis, with good recovery and no further relapses for a long time.
However, in severe cases, there can be a number of attacks which lead to disability. Disability occurs because the body can't always fully recover from damage caused by the attacks on the spinal cord and optic nerve.
