A 35-year-old man presents with known relapsing-remitting multiple sclerosis. His history dates back 4 years with a bout of right optic neuritis initially followed by another event two years ago of right hemi-sensory loss. He has not had any further attacks since then and is not currently receiving any treatment. What is the best recommendation at the current time?
1. Initiate beta-interferon therapy for preventative care
2. Obtain an MRI brain with and without contrast to assess current disease activity
3. Ask to return in 6 months for routine re-examination
4. Place on low dose oral prednisone as a prophylactic agent
