Inclusion Criteria:

Episodes include study neurologist or neuro-ophthalmologist diagnosed: acute optic neuritis, cerebellar, brainstem dysfunction, myelitis, focal cerebral, and/or definitive focal sensory dysfunction.
New objective clinical finding other than a sensory exacerbation, or bowel/bladder signs alone. Sensory deficits alone will not qualify except for optic neuritis.
Subjects may continue on their current immunomodulating therapy (such as interferons or glatiramer acetate) throughout the course of the study. Women who become pregnant after the 5-day treatment of steroids should discontinue immunomodulatory treatment.

Prior use of immunosuppressive treatments within 90 days of index episode (mitoxantrone, azathioprine, IVIg) or plasmapheresis.
Any patient who is pregnant or breastfeeding.
Unable to perform the Multiple Sclerosis Functional Composite consisting of: Timed 25-Foot Walk, 9-Hole Peg Test, and Paced Auditory Serial Addition Test (3 second).
