PATRICK PARCELLS, MD: It's probably going to take a few weeks to potentially even a month to get better, but it may take up to six months. That if you still have any residual problems in six months, that that may last indefinitely. There's a good chance, most of the time, particularly early in MS, most relapses do recover fully.
ANNOUNCER: Currently ms is not curable, but there are medications called interferons that can decrease relapses, and in some cases lessen the damage done.
PATRICK PARCELLS, MD: The average, if you'd look at all MS patients, of relapses, is actually about one per year. And in the studies with the interferons, that average was diminished by about 30 percent.
ANNOUNCER: Relapses may occur even on interferon therapy.
PATRICK PARCELLS, MD: It doesn't mean that there's a failure of interferon. It just means that that relapse still occurred in spite of interferon. I always tell patients there's a greater risk you would be even worse if you weren't on treatment; that you certainly need to stay on treatment.
ANNOUNCER: If treated early, the symptoms of a relapse can be lessened with steroids.
PATRICK PARCELLS, MD: That can certainly make patients feel better, shortens the length of time the relapse will occur, and they will improve more quickly.
ANNOUNCER: Sometimes there is "break-through MS" which means too many relapses or too much progression of disabilities. At that point other drugs may be added to interferon. This is called combination therapy.
