Know the signs of an MS relapse and how to handle it.
When a patient is diagnosed with relapsing-remitting MS, their antennae are automatically up for signs and symptoms of a relapse, which is a short-term flare that involves new symptoms in a specific spot on the body. The symptom usually comes on over the course of days to weeks and then goes away over days to weeks.
There are a lot of misconceptions around MS relapses and how to handle them. Here, neurologist Michelle Fabian, MD, clears things up.
What Are Symptoms of an MS Relapse?
“There are some very typical relapse symptoms of MS,” says Dr. Fabian. Those include optic neuritis (a temporary visual blurring), dizziness, numbness, or weakness. “It’s a localized thing. Either it would be one half of the body or maybe both legs, but something that's localized on the body.”
What Causes an MS Relapse?
The truth is, doctors don’t know. “We don't really understand why a patient has the onset of a relapse but for some reason the immune system turns on and the white blood cells go into the central nervous system and create a new lesion in the brain or the spinal cord,” explains Dr. Fabian. She says there are two things known to make relapses more likely:
1. Infection, like a flu: “If a person has an infection with relapsing remitting MS, most of the time they don't develop a relapse, but sometimes they can,” says Dr. Fabian. What happens is the the immune system gets activated to fight the infection and then continues to attack the central nervous system.
2. Being postpartum: For some women after they have a child, they have an increased risk of having an MS relapse.
How Are MS Relapses Treated?
This might be surprising, but not all MS relapses require treatment. The regular immune-modifying medication patients take helps prevent relapses from happening in the first place. But should a relapse occur, treatment may only be necessary if symptoms are taking a toll on your safety or quality of life.
“We have them come in, we examine them and we monitor the symptoms. The reason we treat a relapse is if a person has trouble functioning. That would typically mean seeing, walking or using their hands or they're in pain, which is rare and then we would use steroids,” says Dr. Fabian. These drugs don’t prevent relapses from happening, but they can help decrease the time the patient has a relapse.
What Should a Patient Do During a Relapse?
First things first, always call your doctor. “I like to worry about it with you,” says Dr. Fabian. “I don't want you to just be at home worrying about that symptom by yourself.” Second, it’s important to know that, with newer MS medication options, relapses actually happen much less frequently; it can be years between them. So a relapse could be a sign that your current MS treatment isn’t working as well as it should be. And your doctor might want to consider changing your treatment plan.
Second, take things easier. Try to avoid activities that will make you feel worse. You might need to take public transportation or drive to work instead of walking, for example. And carve out time for plenty of rest, so you “give your body a break until you can get better,” says Dr. Fabian.
Dr. Fabian is the assistant professor of neurology at The Mount Sinai Hospital in New York City.
00:00:00,000 --> 00:00:03,695
00:00:03,695 --> 00:00:08,692
Relapsing-remitting MS is a form of MS
where a patient only has episodes of
00:00:08,692 --> 00:00:14,310
inflammation or relapses, and
they don't have any signs of progression.
00:00:14,310 --> 00:00:19,200
What that means is they'll have a new
symptom that comes on over days and
00:00:19,200 --> 00:00:22,420
then usually leaves over days and weeks.
00:00:22,420 --> 00:00:24,225
And when they're not having a relapse,
00:00:24,225 --> 00:00:27,330
they're not getting any worse
in terms of their symptoms.
00:00:27,330 --> 00:00:32,629
00:00:32,629 --> 00:00:36,167
The first day people don't usually
know they\re having a relapse,
00:00:36,167 --> 00:00:40,080
because it could just be kind of an off
day, a symptom that's gonna go away.
00:00:40,080 --> 00:00:42,780
But if the symptom is more the next day,
00:00:42,780 --> 00:00:44,870
then especially if it's more the next day.
00:00:44,870 --> 00:00:47,560
That's when I think people really
know that they're in a relapse.
00:00:47,560 --> 00:00:51,570
So there are some very typical
relapse symptoms of MS, and
00:00:51,570 --> 00:00:54,050
those would be optic neuritis.
00:00:54,050 --> 00:00:59,260
So that would be a temporary
visual blurring, dizziness,
00:00:59,260 --> 00:01:04,580
numbness, or weakness and
that's like a localized thing.
00:01:04,580 --> 00:01:08,414
Like either it will be one half of
the body or maybe both legs, but
00:01:08,414 --> 00:01:10,980
something that's localized on the body.
00:01:10,980 --> 00:01:13,860
It's not usually the entire body.
00:01:13,860 --> 00:01:19,060
And we don't really understand why
a patient has the onset of a relapse,
00:01:19,060 --> 00:01:22,040
some reason the immune system turns on.
00:01:22,040 --> 00:01:26,294
And the white blood cells go into
the central nervous system, and
00:01:26,294 --> 00:01:29,398
create a new lesion in the brain or
00:01:29,398 --> 00:01:33,060
There's only two things that we know
that can trigger an MS relapse.
00:01:33,060 --> 00:01:34,620
One thing is an infection.
00:01:34,620 --> 00:01:38,000
So if a person has an infection
with relapsing-remitting MS,
00:01:38,000 --> 00:01:41,870
most of the time they don't develop
a relapse, but sometimes they can.
00:01:41,870 --> 00:01:45,801
We do know that what happens is
the immune system gets activated to fight
00:01:45,801 --> 00:01:46,729
00:01:46,729 --> 00:01:49,390
And then they attack on
the central nervous system.
00:01:49,390 --> 00:01:53,120
The second thing is that some
women after they have a child,
00:01:53,120 --> 00:01:56,460
they do have an increased
risk of having a relapse.
00:01:56,460 --> 00:01:58,970
So, not all relapses are treated.
00:01:58,970 --> 00:02:01,034
It depends on what the relapse is.
00:02:01,034 --> 00:02:04,280
So if a patient is
tolerating the symptoms,
00:02:04,280 --> 00:02:10,080
we actually just have them come in, we
examine them and we monitor the symptoms.
00:02:10,080 --> 00:02:14,900
The reason we treat a relapse is if
a person has trouble functioning.
00:02:14,900 --> 00:02:18,700
That would typically mean seeing,
00:02:18,700 --> 00:02:22,650
using their hands, or
they're in pain, which is rare.
00:02:22,650 --> 00:02:24,540
And then we would use steroids.
00:02:24,540 --> 00:02:29,200
So because the thing with steroids, they
decrease the time a patient has a relapse.
00:02:29,200 --> 00:02:33,490
What's important to understand is that
actually not treating an MS relapse is not
00:02:33,490 --> 00:02:34,790
dangerous in and
00:02:34,790 --> 00:02:40,050
of itself, because the body heals
the inflammation that was there.
00:02:40,050 --> 00:02:44,250
Okay, with or
without treatment that will be healed.
00:02:45,280 --> 00:02:48,940
But the thing is if a person is
having like trouble seeing or
00:02:48,940 --> 00:02:53,320
they can get into problem with that.
00:02:53,320 --> 00:02:56,360
Sometimes when patients
do have a relapse and
00:02:56,360 --> 00:02:59,408
they are not kind of
listening to their body.
00:02:59,408 --> 00:03:03,283
And they continue to do things
to maybe aggravate the symptom,
00:03:03,283 --> 00:03:05,290
that's not a great idea.
00:03:05,290 --> 00:03:08,470
So if somebody's having
tingling in their feet
00:03:08,470 --> 00:03:13,790
they might want to take the bus that day
instead of walking all the way there,
00:03:13,790 --> 00:03:16,710
just to give their body a break
until they can get better.
00:03:16,710 --> 00:03:19,740
A patient should always let us know when
they think they're having a relapse.
00:03:19,740 --> 00:03:21,410
First of all, I just, as a doctor,
00:03:21,410 --> 00:03:24,130
I would always tell a patient,
I like to worry about it with you.
00:03:24,130 --> 00:03:27,510
I don't want you to just be at home
worrying about that symptom by yourself.
00:03:27,510 --> 00:03:28,340
00:03:28,340 --> 00:03:32,330
it is very important, cuz we need to make
sure we have you on the best treatment.
00:03:32,330 --> 00:03:35,410
Patients in the newer
treatments that we have out
00:03:35,410 --> 00:03:38,550
can expect a relapse very infrequently.
00:03:38,550 --> 00:03:41,040
On average, in our trials,
it's like one in every eight years.
00:03:42,250 --> 00:03:45,700
And so because of that, it is a sign
that maybe we need to have a patient on
00:03:45,700 --> 00:03:49,627
a different treatment if they're having
relapse on the treatment they're on.
00:03:49,627 --> 00:03:50,689
