What is neuromyelitis Optica?
neuromyelitis opica is a nervous system disorder that can disrupt vision and lead to weakness or paralysis in the arms and legs. People who have a disorder usually experience sporadic episodes of optical nerve and spinal cord inflammation between periods without symptoms. Symptoms of neuromyelitis Optica are similar to symptoms associated with multiple sclerosis, although these two conditions can be distinguished by the severity of episodes and the amount of brain. There is no medicine, but doctors can prescribe medicines that reduce the frequency and length of attacks. It is an autoimmune disorder in which the immune system attacks the oily lining of nerve cells called myelin. Once the myelin protective coverings are getting worse and deteriorate, nerve cells lose the ability to generate and send impulses in effective pitch.
When the optical nerve is disrupted by neuromyelitis Optica, one can experience eye pain, blurred vision and inability to distinguish colors. Visual problems tend to develop suddenly at the beginning of the episode and gradually deteriorate over the course of many days. Temporary blindness can occur after about two or three weeks during a heavy episode. Weakness, numbness and tingling feelings on the limbs are also common in neuromyelitis Optica and some people experience temporary paralysis. Symptomatic episodes can return every few days or weeks, but many people enjoy months or even years among attacks.
When a patient shows signs of neuromyelitis Optica, specialists can perform a number of diagnostic tests to confirm the condition and exclude multiple sclerosis. Neurological tests are used, computer scanning of tomography and screen for displaying magnetic resonanced want to identify the disintegration of myelin along the optical nerve and spinal cord and ensure that the brain cells are not inflamed. Patients looking for consultations during a period without symptoms can show very few signs of chronic disorder so they can be afterRequired to return when episodes appear.
After confirming the diagnosis, the physician may provide corticosteroids such as prednisone to relieve the immediate symptoms of pain and inflammation. In order to reduce the chances of frequent future episodes, immunosuppressive drugs can be prescribed to patients to marry daily. Most people who use their medicines still have occasional attacks, but are less serious. If serious problems continue to be repeated, the patient may need to receive regular blood plasma transfusions to dilute autoimmune response.
