Symptoms can range from mild to severe depending on what part of the brain, spinal cord, or optic nerves have been affected. Symptoms may last for a few days or be permanent. They may also improve and then come back months to years after they have initially occurred. In some cases, even though the initial symptoms improve, you may have permanent changes that your doctor is able to detect during your exam.
