Since about 85% of people with MS have relapses, you’ve probably had personal
experience with relapses. A relapse is a period where MS symptoms get worse
or new symptoms appear. These symptoms may include fatigue, vision problems,
bowel or bladder problems, abnormal sensations, or difficulty walking.

In order to be considered a relapse, this period must last for at least 24
hours, and must occur at least one month after the last relapse. Otherwise,
it is considered a pseudorelapse – see "MS pseudorelapses: smoke
and mirrors?" in this health feature. Most relapses develop over about
a week, and resolve slowly over weeks to months. Relapses are also known as
exacerbations or flare-ups.

So what is happening in the body during a relapse? An area of brain tissue
becomes inflamed, leading to the destruction of myelin, the protective coating
of nerve cells. This is also known as demyelination, and leads to the
worsening of neurological symptoms. It is not known exactly why relapses occur,
but this is part of the underlying disease for people with relapsing forms of
MS.

Once the relapse is over, MS symptoms return to their baseline level (the level
they were at before the relapse started). This is known as a remission. "Remission"
does not mean that all MS symptoms have disappeared, just that they have gone
back to their pre-relapse levels.
