What Is Refractory Epilepsy?
[MUSIC PLAYING]
JOHN WHYTE: Welcome, everyone.
I'm Dr. John Whyte.
I'm the Chief Medical Officer
at WebMD.
Today, I want to spend some time
with you talking about
epilepsy, particularly
sudden unexpected death
in epilepsy.
Joining me to help provide
insight are two experts.
Dr. Stephan Schuele; he is chief
of Epilepsy
and Clinical Neurophysiology
in the Department of Neurology
at Northwestern Medicine.
And Tom Stanton;
he's the president of the Danny
Did Foundation.
Gentlemen, thanks for joining
me today.
STEPHAN SCHUELE: Thanks
for having us.
JOHN WHYTE: Stephan,
I want to start off with--
can you provide an overview
for the audience of what we mean
by sudden unexpected death
in epilepsy?
We've heard about sudden death
in heart disease, but what does
it mean when we're talking
about epilepsy?
And do we know the risk factors?
STEPHAN SCHUELE: Very
good question.
Yeah, you know, when we think
about seizures and epilepsy,
we kind of-- everybody
can imagine that you can have
a trauma, or you could drown
from a seizure.
You can be involved
in an accident.
But I think what a lot of people
are not aware of is the fact
that you can actually die
from a seizure itself.
You know, the seizure can be so
strong that you don't wake
up afterwards.
That is, fortunately, extremely
rare and happens, you know, in 1
in 1,000 patients a year.
So if I see 1,000 patients,
it happened in one patient.
But obviously, it happens
in my practice
because I see patients every day
with epilepsy.
It is even more common
in patients who have really
bad epilepsy.
So that's one of the
risk factors.
So patients that are not
controlled on their medications,
the risk goes up.
To keep it in perspective--
most patients with epilepsy
are otherwise healthy.
You know, it affects you
in your best years of
life often.
JOHN WHYTE: That's why advocacy
is so important-- helping
explain to folks with epilepsy
and their caregivers,
what sudden unexpected death
may mean,
as well as the general public.
As you alluded to, there's
some misconceptions.
So, Tom, tell us a little bit
about the mission
and what's your objectives.
TOM STANTON: Sure, thanks, John.
You know, when we started,
unfortunately, it was
after a tragedy
that our family experienced.
My nephew, Danny, had epilepsy,
was diagnosed around the age
of 2.
And like Stephan alluded to,
he was otherwise healthy,
which is oftentimes the case
for people with epilepsy.
He had about four seizures over
the next 2 and 1/2 years that
his parents witnessed.
And they were all during sleep,
which is something that,
you know,
some people aren't even
aware of that seizures can
happen during sleep.
And it's fairly common.
Danny was 4 and 1/2 and he went
to a routine checkup with
his neurologist.
They adjusted his medication
based on weight gain.
And it was 4 days later
that his mom found
him unresponsive.
He had been lost,
and they didn't know why.
It wasn't until the death
certificate was administered
that they saw this term SUDEP.
And it was just this kind
of shocking experience.
Not only did they lose
their son, who they had been
with the day prior,
but they lost it to a risk
that they had never been
counseled about, they had never
heard of.
And so his parents decided they
didn't want that to happen
to other families
and established that Danny Did
Foundation to help
other families avoid
that scenario.
JOHN WHYTE: Thank you, Tom,
for sharing that story
and to his parents as well,
which really helps us to
better advocate.
Tom, where are we kind
of in this landscape
of educating folks,
raising awareness?
Because in some ways,
we want to remind people
that you can have a normal
life, right?
You might have to have
some adjustments.
But then we want to say,
but wait, you have to be
alert to this issue
of sudden unexpected death.
How do you bridge that
and provide good information
for folks?
TOM STANTON: I think for us,
it involves working both sides
of the equation.
So we talk with patients
and caregivers about the fact
that they're being empowered
with this information.
It's given from a place
of power, empowerment and
not fear.
And sometimes patients
or caregivers have to instigate
the discussion so
that the doctor feels that they
have permission to move ahead
with the conversation.
On the flip side, we really
encourage physicians to openly
discuss SUDEP for a variety
of reasons.
One, both the AAN and the AES,
they both recommend disclosure.
There was a 2017 SUDEP guideline
in which they recommend
disclosure for all people
with epilepsy.
Another factor is that patients
and caregivers really desire
to be informed.
JOHN WHYTE: Stephan, what's
your strategy at Northwestern?
How do you approach
these discussions?
Or in some ways, what do you
want viewers and listeners
to hear in terms
of the questions
that they may think
about asking?
STEPHAN SCHUELE: I look at it
in the broad context
of education.
You know, when you have
your patient coming
with the first seizure,
they have--
many of them have questions
which fill a full hour.
And I think that that
is correct, you know?
If I would have
my first seizure, I would have
an hour of questions for you.
So I think if you create
a culture of education
and being open for questions
of your patients,
I think that's probably the most
important aspect to actually
lead into discussing SUDEP
as well.
And then, obviously, education
for ourselves.
My nurses know about SUDEP.
All my residents and fellows
know about SUDEP.
And we have several lectures
a year, which focus on the topic
of SUDEP.
JOHN WHYTE: Tom, Danny Did has
a lot of resources for patients,
for parents, for caregivers.
Tell us about some
of these resources
and how folks can access them.
TOM STANTON: I think
one of the most
important resources
is just to help patients
and caregivers know
the questions to ask
their doctor to help them tailor
their individual risk level.
I think that's really
important in terms of coming up
with a modified treatment plan
is to know where do they fall
on this risk spectrum.
And I think knowing what
those risk factors are.
So Stephan mentioned a few
of them, both of which
impacted my nephew.
Even though he didn't have
a high volume of seizures,
he had convulsive seizures.
They happened during sleep.
So I think just knowing
the questions to ask,
knowing what the risk factors
are, feeling like you have
permission to instigate
the conversation.
And those are all things
that people can learn more about
on our website, which
is dannydid.org.
In that worst case scenario,
John, where someone has lost
someone to SUDEP,
that's another way that we can
support, not the way that we
want to, but offering just
bereavement support to let them
know that they're not alone
in suffering this kind
of horrible loss.
And that there's a community
around this thing
called SUDEP is another way
that we're there for families.
JOHN WHYTE: Well, I wanted
to ask about this concept
of community,
because you're really building
a sense of community.
Tell us about that.
TOM STANTON: Yeah, I think
there's really no disease state
that has achieved progress
without that drive and urgency
that comes from parent advocacy.
And that's really what we were
founded on, is just two parents
that wanted to carry their
son forward.
Epilepsy can be a really
isolating disease.
There's a lot of stigma
around it.
So bringing people together
in environments that allow them
to not only gain information
and resources,
but really to form relationships
and social bonds,
too, is something that's
important to us.
We also have an event that we
co-host called Partners
Against Mortality in Epilepsy,
or PAME.
And it's really focused
on moving forward solutions
around what causes SUDEP?
How can it be prevented.
What kind of research
do we still need to learn more
about it?
And that meeting is really
the only place that we know
of where people have lost
a loved one to SUDEP
can come and talk
with other families
and gain some resources
and support.
JOHN WHYTE: Stephan,
in your mind, what are
the priorities
or the initiatives
that we need over the next year
or 2
in order to reduce the incidence
of SUDEP?
STEPHAN SCHUELE:
For many patients with epilepsy,
understanding what is the
best treatment
and how vital is their treatment
really starts in some way
with understanding what
the worst thing is which can
happen to them.
You know, my patients don't have
pain every morning to take
their medication.
They take their medication so it
gets them through the
day safely.
And I think that knowing
about what they are preventing
with taking their medication I
think is an important aspect
of SUDEP.
You know, I think number two is
we are--
Northwestern is a big
epilepsy center.
We offer epilepsy surgery
for patients.
And we recently realized
that actually the patients who
are successful
undergoing surgery
have reduced risk of dying
from SUDEP than patients who
are not candidates or choose not
to go down that route.
So I think that's another aspect
that there are treatments which
are available, which I think
we want to make
sure patients understand
that they're there.
I think there's a big push
in the epilepsy community
for better seizure detection
and recognition of seizures.
So bed alarms, wrist alarms,
things which can make patients
feel safer and also family
members be quicker in responding
I think is an important aspect
to it.
And then, lastly, is, obviously,
we want to understand
the actual mechanism of SUDEP,
which is more research driven.
What makes someone to stop
breathing or the medication
which can prevent that
from happening
from the flattening of the EEG
and the lack
of respiratory drive
to catch a breath
and come out of it, you know,
which is all what it needs
to get out of there.
I think we are working hard
on understanding
those mechanisms
and maybe have medications
eventually or stimulators
or other devices which can
resuscitate
patients successfully.
JOHN WHYTE: Well, certainly
there is more work to be done,
more research, more awareness.
I want to thank you both
for really leading the charge
in how we raise awareness
of SUDEP
and how we can better manage it.
So thank you both.
STEPHAN SCHUELE: Well, thanks
for having us.
[MUSIC PLAYING]
If your doctor says you have refractory epilepsy, it means that medicine isn't bringing your seizures under control. You might hear the condition called by some other names, such as uncontrolled, intractable, or drug-resistant epilepsy.
Your doctor can try certain things to help keep your seizures under better control. For instance, they might try different combinations of drugs or a special diet.
Your doctor may also put a device under your skin that sends electrical signals to one of your nerves, called the vagus nerve. This may cut the number of seizures you get. A Neuropace device is a reactive neurostimulator that detects seizures and shocks the brain to stop them.
Surgery that removes a part of the brain that causes your seizures may also be an option. With any of these treatments, you may still need to take epilepsy medicine throughout your life.
It's natural to feel anxious when the doctor tells you your epilepsy isn't getting better with the medicine you're taking. You don't have to go through it alone, though. It's important to reach out to family and friends to get the emotional support you need. You might also want to join a support group, so you can talk with other people who are going through the same things you are.
Causes
Doctors don’t know why some people have refractory epilepsy and others don't. You can have refractory epilepsy as an adult, or your child might have it. About 1 in 3 people with epilepsy will develop it.
Symptoms
The symptoms of refractory epilepsy are seizures despite taking anti-seizure medication. Your seizures could take different forms and last from a few seconds to a few minutes.
You may have convulsions, which means you can't stop your body from shaking.
When you have a seizure, you may also:
- Black out
- Lose control of your bowels or bladder
- Stare into space
- Fall down suddenly
- Get stiff muscles
- Bite your tongue
Getting a Diagnosis
Your doctor has several ways to diagnose refractory epilepsy. They may ask you questions such as:
- How often do you have seizures?
- Do you ever skip doses of your medicine?
- Does epilepsy run in your family?
- Do you still have seizures after taking medicine?
Your doctor may also give you a test called an electroencephalogram. To do this, they'll place metal discs called electrodes on your scalp that measure brain activity.
Other tests might include a CT scan of your brain. It's a powerful X-ray that makes detailed pictures of the inside of your body.
You might also need to get an MRI of your brain. It uses magnets and radio waves to make pictures of your brain.
If you need surgery to treat refractory epilepsy, these tests can help doctors find out where your seizures are starting.
Your doctor will most likely want you to report your symptoms regularly. They may try several drugs at different doses.
Questions for Your Doctor
- What might be causing my seizures?
- Which tests are needed to diagnose refractory epilepsy?
- Should I see an epilepsy specialist?
- What treatments are available for refractory epilepsy?
- What precautions should I take to avoid getting injured during a seizure?
- Are there any limits on my activities?
Treatment
Medications. Your doctor may take a second look at the drugs you're taking. They may suggest another medicine, either alone or combined with other drugs, to see if it helps you have fewer seizures.
Many drugs can treat epilepsy, including:
- Brivaracetam (Briviact)
- Cannabidiol (Epidiolex)
- Carbamazepine (Carbatrol, Tegretol)
- Cenobamate (Xcopri)
- Clobazam (Sympazan)
- Divalproex (Depakote)
- Dilantin (Phenytek)
- Eslicarbazepine (Aptiom)
- Felbamate (Felbatol)
- Gabapentin (Neurontin)
- Lacosamide (Vimpat)
- Lamotrigine (Lamictal)
- Levetiracetam (Keppra)
- Oxcarbazepine (Trileptal)
- Perampanel (Fycompa)
- Potiga (Ezogabine)
- Primidone (Mysoline)
- Rufinamide (Banzel)
- Tiagabine (Gabitril)
- Topiramate (Topamax)
- Vigabatrin (Sabril)
- Zonisamide (Zonegram)
Surgery. If you still have seizures after trying two or three anti-epilepsy drugs, your doctor might recommend brain surgery.
It can help a lot if your epilepsy only affects one side of your brain. Doctors call that refractory partial epilepsy.
A surgeon removes the area of your brain that's responsible for your seizures.
It's natural to worry about brain surgery and to wonder if it will affect the way you think or if you'll seem like a different person afterward. Talk with your doctor about what to expect if you choose the surgery or if you don't, so you can weigh the risks and benefits. A lot of people who have the surgery say that getting free of seizures -- or at least making them less common and less intense -- makes them feel much better.
The surgeon usually operates on an area of your head that's behind your hairline, so you won't have noticeable scars.
After it's done, you'll probably need to stay in an intensive care unit of the hospital for a few days. After that, you'll move to a regular hospital room, where you may need to stay for up to 2 weeks.
You should take it easy for a while after you get back home, but you'll probably be able to return to a normal routine in 1 to 3 months. Even with the surgery, you might need to take seizure medication for a few years. You might need to stay on the drugs for the rest of your life.
Talk to your doctor about any side effects you might have from the surgery. You can ask them to put you in touch with other people who've had the surgery, so you can better understand what to expect.
Diet. The ketogenic diet may help some people with epilepsy. It's a high-fat, low-protein, no carb diet. You have to start it in a specific way and follow it strictly, so you need a doctor's supervision.
Your doctor will watch closely to see whether or when you can lower any of your medication levels. Because the diet is so specific, you may need to take vitamin or mineral supplements.
Doctors aren't sure why the ketogenic diet works, but some studies show that children with epilepsy who stay on the diet have a better chance of reducing their seizures or their medications.
For some people, a modified Atkins diet may help, too. It's slightly different from the ketogenic diet. You don't have to restrict calories, protein, or fluids. Also, you don't weigh or measure foods. Instead, you track carbohydrates.
People with seizures that are hard to treat have also tried a low-glycemic-index diet. This diet focuses on the type of carbs, as well as the amount that someone eats.
Electrical stimulation, also known as neuromodulation. This technology works directly on your nerves. It changes or controls nerve activity by sending electrical signals or medicine to a specific area. Methods include:
- Cortical stimulation. Temporary electrodes are placed on the surface of your brain. The doctor sends a signal through them at a level low enough that you won’t notice. If it helps, they can be replaced with permanent electrodes for continuous stimulation.
- Closed-loop stimulation. The doctor implants a device under your scalp and within your skull. It’s connected to two electrodes placed either on the surface of your brain, in the brain, or both. The electrodes record your brain waves. When the neurostimulator detects seizure-like activity, it sends a small electrical current to your brain that can stop, shorten, or maybe prevent the seizure.
- Deep brain stimulation. The doctor implants thin electrodes deep into certain areas of your brain and a pulse generator under your collarbone. Wires under your skin connect the two. The pulse generator sends signals to disrupt abnormal patterns of brain activity.
- Vagus nerve stimulation (VNS). The doctor puts a device that looks like a heart pacemaker under your left collarbone. It connects to the vagus nerve in your neck through a wire that runs under your skin. The device sends a current to the nerve, which may cut down on the number of seizures you get or make them less intense.
Clinical trials. You may want to ask your doctor if you could take part in a clinical trial. These trials test new drugs to see if they're safe and if they work. They're often a way for people to try new medicine that isn't yet available to everyone.
Taking Care of Yourself
Stress can sometimes trigger seizures. Talking to a counselor is a great way to find solutions to manage your stress.
Try going to a support group, too. You can talk with people who know what you're going through and who give advice from their own experience.
What to Expect
Even though you have refractory epilepsy, it's still possible to get your seizures under control. It may be a matter of switching to a different treatment.
Your doctor may find a different drug combination that helps. Getting electrical stimulation of the vagus nerve means fewer seizures for about 40% of people who try it. And if a brain surgeon can remove the part of the brain that's causing seizures, the seizures may stop, or at least happen less often and become less intense.
Getting Support
As you are finding out what works best, you'll need a strong network of family and friends who can offer emotional support, especially if your seizures prove hard to control. Having a trusted person to listen to you can be a great comfort when you're going through something tough.
Ask your doctor for information on support groups in your area. You can also find out about support groups by going to the website of the Epilepsy Foundation.
