Migraines in children: Guidelines for primary care management of headache

September 2, 2019

– So I’m gonna talk most of the time but I’m also gonna share the platform with Emily Foxen-Craft. Dr. Foxen-Craft is a
Pediatric Psychologist interested in pain and
she’s gonna talk about part of the management
of headaches with me. So when we talk about, let’s see how this is working. – This one’ll work. – There we go. – Just want a little flash
up there it takes a second. – All right, you can talk out loud. – It’s coming. – (laughs) So when we’re
talkin’ ’bout headaches in kids, there’s no disclosures here, it’s very easy for us
to makes lists like this of what’s a primary headache and what’s a secondary headache. Where a primary headache is
if you treat the problem, you’ve got it solved,
whereas a secondary headache is a headache that’s due
to an underlying cause and you really have to find the cause. Most of the headaches we see
in kids are migraine headaches. We’ll come to tension-type headaches. It’s very, very unusual to
see cluster headaches in kids. I think I’ve seen that twice in my career. Secondary headaches are fairly common. Most of the time they’re
fairly easy to recognize. And probably the most common we see is because of depression. When people have sinus disease it’s usually fairly straightforward. Tumors and mass lesions we’ll talk about in terms of increased
intracranial pressure, similar to with hydrocephalus. I’m not gonna have enough time
to talk about pseudotumor. But these all present with
increased intracranial pressure. Meningitis is again usually
fairly straightforward with a stiff neck and meningeal signs. Although these might not be present in kids under two years of age. Subarachnoid hemorrhages happen in kids, they’re much less common than adults. But if you do see a sudden onset of a worst headache of somebody’s life, then you have to think about it. Usually you can diagnose it with CT scan, but about 8% are missed and
you need an LP for that. Seizures commonly have
headaches postictally. So it’s not unusual for
a child who has a seizure to have the seizure resolved
and have a headache. It’s fairly unusual for a headache to be the sole manifestation of a seizure. And it tricks us sometimes
because the headaches tend to be brief, come and go periodically throughout the day. But most of those headaches
that come for a few seconds or a couple minutes and go away, are really benign headaches. And we see them pretty commonly in kids. In young kids we see those
waking the kids up at night. Temporomandibular joint dysfunction can present with headaches
but perhaps more commonly, headaches can result from teeth clenching. If you keep your fist
contracted for an hour, you build up lactic
acid, you get headaches. The same thing with people
clench their teeth at night. It’s sort of a reflex when
somebody, a kid presents with a headache to send
’em to an eye doctor to get their refraction checked. That’s pretty unusual as
a cause of a headache. If you do cross your eyes,
your pupils constrict, your depth of focus increases, like you’re stopping down
an aperture of a camera and you can see better and
that can give you a headache. But most kids don’t do that. On the other hand, sleep problems are real common causes of headaches. Kids not getting enough
sleep, sleeping poorly. High blood pressure can cause headaches, but it also can result
from increased pressure. And then, more and more kids are drinking lots of caffeine energy drinks and withdrawal can cause
seizures, headaches. Increased intracranial pressure, classically you have progressive headaches that worsen with lying down. Because there’s high pressure,
they wake you at night and are present first
thing in the morning. They can be associated
with mental status changes. Nausea and vomiting, but
though these are really not specific ’cause we can
see those with migraines. And obviously papilledema. You can get a sixth nerve palsy, reminding you the sixth nerve
controls the lateral rectus so your eye tends to go inward because you can’t abduct the eye. This is a false localizing thing as sixth nerve gets
compressed or stretched. In infants who have high pressure, they can develop macrocephaly
or bulging fontanelle, or can have something called sunsetting in which the pressure in the midbrain keeps their eyes from going up, so it looks like their eyes
are setting in their orbits. That’s a sign of increased ICP. Tension-type headaches, we
don’t say tension headaches anymore because the muscle
tension actually isn’t increased, but classically as a
diffused band-like headache. Described as aching, kind
of non-specific complaints. Often resolved with minor
over-the-counter analgesics. Typically no nausea or vomiting
but increase with stress. But the increase with stress
is certainly not specific. That happens with migraines. Migraine with aura. So about 10 or 15% of
migraineurs have an aura. They don’t have to have
it with every headache. An aura is a neurologic dysfunction. So it can be a negative thing, I lose my vision or get blurry vision, or a positive phenomenon, I
see things that aren’t there, sparkles, dots, zig-zag lines. If they have a unilateral headache, the aura is usually contralateral to that. And visual symptoms resulting
from occipital involvement are most common, but you
can have sensory, motor, language, cognitive, or
cerebellar dysfunction. When my wife was pregnant the first time, she developed an aphasia, and I brought her to the obstetrician, everything were checked out okay. And she was nice enough to develop a left-sided throbbing headache when the neurology resident
walked in the room. So it’s not unusual something like that. The visual symptoms. Classically you have, this
is where you’re looking, a zig-zag line that’s expanding and leaves a scotoma behind. But you can get sensory, motor, or language like I mentioned. The headache is usually throbbing. In adults it’s classically unilateral. In kids it’s more commonly bilateral. It can be frontal or temporal, although sometimes we
see them occipitally. Gradual onset, going on
over minutes to hours. Classically two to six hours. Usually it’s shorter in
children than adults. And classic for migraines,
activity worsens the headache. So running in gym class, going up stairs. And it’s very classic for
sleep to improve the headaches. Even sometimes a nap. A lot of GI symptoms, loss of
appetite, nausea, vomiting. They can get very tender
to non-specific things. So somebody has a migraine, you touch their forehead, it hurts. That’s a phenomenon called allodynia. And then very classically,
photophobia or phonophobia. Light or noise sensitivity,
one or both, but not always. Migraine without aura is more variable. There’s often personality changes, a vague dizziness, malaise. The headache may be
unilateral and pounding, often hard to describe. Again can go on for
variable periods of time. And classically when somebody
has a migraine with aura, they throw up, they feel better. With migraine without aura,
that tends not to happen. Triggers, most of the time
people have migraines, there’s no specific trigger. But the ones we see are
stress, head trauma. Dr. Ichesco will talk a
little bit more about that. But even without a concussion, just lightly bumping your
head can bring on a migraine, heading a soccer ball. Certain foods, that’s fairly uncommon. When they’re doin’ careful studies, maybe 10 or 15% have a
specific food trigger. Menstrual cycle, so 60% of women have worsening of their
migraines with their periods. And 15% have exclusively
with their periods. Even if you get enough sleep,
changing your sleep habits will often bring on migraines. So staying up late Friday
night and Saturday night, bringing on headaches later. Missing meals is classic. And then certain odors such as perfumes, very classic for bringing on headaches. Family history. So if you had to guess,
what percent of children with migraines have a family
history of one or both parents? Just think about it for a second. It turns out to be 80 or 90%. Now the issue is getting the history. So I can’t tell you how
many times I’ve asked, Does anybody get migraines? The answer is no. Well I’m gonna start Billy on medicine X. Well that didn’t work for my migraines. I thought you didn’t get ’em? (audience laughing) Well, I don’t, I used to. Or, I don’t get migraines,
I get sinus headaches. I get sick to my stomach, I see sparkles and lights and noise bother me but it’s because of my sinuses. So you really have to ask, does anybody now get headaches
or get headaches in the past? The other things that’s
specific to pediatrics or more common in pediatrics
is migraine variants. A lot of what we see
aren’t really presenting with the headaches as
much as other things. We talk about complicated migraines as migraines with a non-visual aura. So any of the other
things that we talk about, there’s ocular migraines, in which you lose vision in one eye. Most of the people that come in and say, I had a headache and I lost
vision in my right eye, are really talking about
a right hemianopsia. It’s the same if you cover
the right eye and left eye. Occasionally have a
very astute kid comes in and says, I lost vision in my right eye. I could see perfectly well
when I cover my right eye, and I’m totally blind
when I cover my left eye. The retina’s involved in the migraine. The retina we can think
of as part of the brain. Opthalmoplegic migraine
affecting the cranial nerves. Basilar migraines are very common, they often present with syncope. So it’s two or more brainstem features. So loss of consciousness, your
reticular activating system keeps you awake. Ataxia, tinnitus, double vision, the brainstem keeps your eyes aligned. Bilateral sensory symptoms as the fibers come up from your neck. We see kids with acute
confusional migraines. It’s basically up to 24 hours of delirium. Come to the ER, can’t tell
if they’re have encephalitis or complex partial seizures. Then it becomes clear it’s a migraine. You can get an aura without a headache, so the visual changes or vertigo is one of the common presentation. One of the common causes of
vertigo in kids is migraines. Certain genetic things can
cause hemiplegic migraines that run in families. Trauma-induced migraines. The British literature is full of people who headed a soccer ball
and went blind for an hour, with our without a headache, and it’s a migraine aura with that, they may not have a headache. There’s something called
benign paroxysmal vertigo. It seen in infants. So they may all of a
sudden fall to the ground, look terribly distressed. The astute mother may
notice the eyes are going boom, boom, boom, boom, there’s nystagmus. Goes on about 10 minutes. If the kids are old enough,
they may say they’re dizzy. And then it goes away. They often have a family
history of migraine. Often evolve into more typical migraines. Similarly there’s something called benign paroxysmal torticollis, where, oops, skip that, where kids are like that for a day or two. They’re terribly distressed,
they’re vomiting, and goes on and may evolve
into more typical migraines. And then cyclic vomiting. If people who have migraines
often present initially with just a lot of vomiting,
evolve into migraines. About half the cyclic
vomiters, are migraineurs, it’s hard to know, so it’s
a matter of treating them. But if it doesn’t work,
you don’t have a diagnosis, ’cause the treatment
doesn’t work for everything. Complications of migraine. So just real quickly, status migrainosus is having a migraine
going on for 72 hours. Different from people who
have chronic, daily headaches. Kids often come to the ER
with dehydration, vomiting. Migrainous infarction, so
higher risk of having strokes if you have migraines,
the reasons aren’t clear. Sometimes they’re tiny,
little things like this. But sometimes they’re bigger. Higher risk of cardiovascular disease in people with migraines
but it’s not clear why. I’m gonna focus the rest
of the talk on treatment. So a lot of it is reassurance. There’s a huge amount of anxiety in kids and in parents of kids who
come in with migraines. A lot of times just telling
them this is not a brain tumor is enough to make the headaches better, because you’re relieving anxiety. If there’s clear precipitants,
we try to avoid those. Every time you smell perfume,
well don’t smell perfume. It’s hard to avoid stress,
but Dr. Foxen-Craft will talk a little bit about that. Getting enough sleep, sufficient sleep. And I’ll talk about
abortives and preventatives, but I want Dr. Foxen-Craft to come up and talk about behavioral treatments. Oops, I guess that we
got out of order here. So I’ll talk about abortives first. So just, these are better
if you use at the onset. For most people,
over-the-counter medications seem to work quite well. There are prescription medications, triptans that work quite well. Some are approved for kids, some aren’t. Sometimes they’re combined with naproxen. There’s a number of combinations
of various medications that seem to work well for migraines but sometimes not covered by insurance. And then the barbiturates such
as butalbital seem to work but can cause kids to get really sleepy. A number of other medications. Occasionally we’ll use narcotics but we really want to avoid those except in kids who maybe have, once or twice a year, killer headaches that nothing else seems to work, and then I’ll use it for them. Steroids we tend to use for kids we can’t break the headache. Sometimes they work, sometimes they don’t. I’ll use a five-day prednisone burst. And then we’ll use a
variety of antiemetics for kids who have a lot of vomiting. Let’s talk about a few
preventative medicines. For a primary care doctor,
what I would recommend is getting familiar with one or two preventative medications,
getting comfortable using them and feel free to use them. We use preventative medicines in kids who have at least one or
two headaches per week, particularly if they’re moderately severe. We’ll often use them for six to 12 months if the kids are doing well, then we’ll taper the medications. I’ll go through some of
the medications we use, but we tend to use antihistamines, tricyclics, calcium channel blockers, seizure preventatives, and beta blockers. Cyproheptadine’s the one
that’s the easiest to use. It’s an antihistamine. It comes in a liquid, it comes
in a four milligram tablet. Typical dose for a really little kid, I’ll start with two milligrams a day. It’s usually divided BID, but
because it makes people sleepy we sometimes just give it at bedtime. And it seems to work quite will there. The two main side effects are
sleepiness and weight gain. Small kids seem to tolerate
it better than teenagers. But if I have a very, very
thin teenager who can’t sleep, I’ll often use it in
that situation as well. It works quite quickly,
so I’ll sometimes use it when I really need to
treat headaches urgently. Tricyclics either
nortriptyline or amitriptyline. My sense is amitriptyline works better but has more side effects. Comes in a variety of pill sizes. Usually start, what I
tend to do is I start low, because I don’t want people
to have side effects. Usually 10 milligrams at
bedtime and build up weekly. I used to build up toward
75 milligrams at bedtime, and now I go toward 30. May have a month or two latency of onset. Lots of side effects, sleepiness, orthostatic hypotension,
you can get dry mouth, weight gain, mood changes. The most dangerous side
effect is arrhythmia so I really wanna make
sure there’s nobody, they’re not suicidal, there’s
no little kids at home. And I’ll, I tend to use
them as a 1st line drug, but also in kids with
chronic, daily headaches. I tend to get an EKG first. Ron can say whether it’s
cost effective or not. But what tends to happen is I build up to a large dose eventually and I see these little changes in the EKG. I’ll go to the cardiologist, I’ll say, “Is it from the tricyclic?” They go “I don’t know, what’d it look like “before you started?” So I tend to get them but. (audience laughing) Topiramate’s an anti-seizure medicine. It comes in tablets, sprinkles,
you can make a suspension. We use much smaller doses of this for migraines than we use for seizures. So I’ll tell a teenager I’m using what I use for a six
month old with epilepsy. Large number of side effects. Most common are loss of
appetite, and not sweating. But it can cause a lot of confusion, word-finding difficulty. You know, why did you put me on Stupimax? (audience laughing) But I tend to use it as
a 2nd line medication or in overweight patients
because of the weight loss. We tend to use verapamil in kids. It doesn’t work on adults. It can take a long time to work. I usually start it at 80
or 120 milligrams a day. The 120 has a long-acting form. Again, may take a month or two to work. The two most common side effects are orthostatic hypotension
and constipation. And I tend to use it for
complicated migraines, patients with non-visual auras although there’s very little
if any data to support that. And then there’s a number
of people who are using combinations of vitamins and cofactors. A number of commercially
available combinations. People tend to use these when
there’s a preventative needed but really, parents, I don’t
want my kid on a medicine, but I can use a combination of vitamins. Not a lot of data about
whether they work or not. What works best? So there’s finally a multi-center trial called the CHAMP study published
in the New England Journal in November 2016 comparing amitriptyline, topiramate, and placebo for migraine. Primary outcome was 50%
reduction in headache days. Amitriptyline worked 52% of the time, topiramate 55% of the time,
placebo 61% of the time. (audience laughing) Similar for all secondary outcomes. So we don’t know what to do. (audience laughing) And they stopped it for futility. The people running this study still tend to use
amitriptyline and topiramate. Maybe they weren’t using
enough in this study and we, you know, it’s really unclear. A lot of the people in our group have gone to these
vitamin and cofactors now. Because they say, well these medicines cause more side effects than placebo and they don’t work as well so. But we just don’t know. 20% of the migraineurs develop
these chronic headaches. You get these patterns where
these episodic headaches build up and there’s a
chronic headache going on. And they’re often a combination of tension or mixed tension-like. They’re often postconcussive,
they have dizziness that’s often vague, fatigue,
missing a lot of school. And when these happen, you
have to look for depression, psychosocial issues and abuse. And we really want to avoid the situation where they’re taking, you know, acetaminophen or ibuprofen every day. And these are the situations,
this was the trigger I was supposed to be using
for behavioral interventions at this case, ’cause
that seems to work best in these patients. – Hi I’m Emily, thank you
so much for having me here. So I’m here to talk to
you about a couple things that you might consider
incorporating in your practice in terms of managing
migraines that have very few to no side effects, so here we go with non-pharmacological
management techniques. So the two categories I usually work in and recommend considering are optimizing either what we call the lifestyle factors, or headache hygiene factors in terms of managing their headaches. And in these I sometimes
conceptualize it with patients like, think about it like a pie chart, like, all these different
things are gonna be things that affect your headaches. Let’s try to find the ones that are big ingredients for you, as well as anything that we can do to manage stress, to prevent triggers, or prevent
this overall stress level that may be maintaining chronic headaches. So some of the lifestyle factors that we really consider like
we’ve mentioned here all day are sleep, but also hydration, nutrition, getting regular physical activity, as well as considering
medication adherence. Are the kids actually
taking the medications they’re prescribed regularly and with appropriate timing and doses. So I’ll talk briefly about
one of the main things that I find most complicated
but very effective to help with migraines and
that is addressing sleep. So we know that kids and teens these days are definitely overall not
getting enough recommended sleep but there’s been studies to suggest that the migraneurs and pediatric
kids with headaches get less sleep even than
their same-age peers. And what we also starting to understand is that the headaches can be correlated with the worse sleep. So as we’re probably all expecting, this is likely bidirectional, headaches causing poor sleep,
poor sleep causing headaches. The families or patients that
are presenting to your office may have their own theory
about the direction of that, but what we’re starting
to understand is really addressing the sleep, even
though it may be viewed as an effect of the
headaches, can actually really dramatically
improve their outcomes. And it’s important to recognize that these other behavioral interventions that we’re gonna be
considering, are less likely to be effective if these
kids are sleep deprived. So some of the targets, we
often talk about screen time. But other really helpful outcomes or targets to consider
are the consistency. So like we’ve talked about a lot of kids have very disrupted sleep schedules between the weekends and weekdays, or are just like kind
of all over the place. Like I don’t normally go to
bed around the same time, so trying to get them on a somewhat of a consistent sleep schedule
can be really helpful. And sometimes that needs
to be a gradual change as opposed to a sudden change. But I also like to make
sure I don’t underestimate the effects of conditioning
with the bedroom and the bed. So some two recommendations
to consider with kids are making sure that they are
only using the bed for sleep. A lot of the kids will tell you, like, I do my homework in bed,
and I do my Netflix in bed, and I’m Snapchatting in bed,
and all that good stuff. And that creates an
association with their bed and their bedroom that this
is not a place for sleep. So it’s a pretty powerful
effect to remove all of that from the bed, only do
sleeping activities in bed, and see if that starts to have an effect after done consistently
for a little while. Similarly, a conditioning effect can occur when they’re tossing and turning, having difficulty falling asleep at night or waking up frequently. So we try to break that cycle
by getting the kids out of bed when they can’t fall asleep. Engaging in a quiet,
non-screen related activity and going back to bed when
they are ready to go to sleep. So picking and choosing, experimenting and trying to find what
recommendations work for them. And I do this process usually through just some simple
motivational interviewing. Help engaging them in problem solving, as opposed to telling them what to do ’cause they’ve been told all
over again to sleep better. So sometimes that gets you
a little better success. Stress reduction is another
big area that we consider with managing headaches and
migraines through behavior. We really view this as a
self-management approach. This is something that
the child or teen can do for themselves to help their symptoms. And when practiced
regularly, can actually, there’s a meta-analysis a little
while ago that showed that about 50% of outcomes were improved in about 50% of pediatric patients. So that was sometimes frequency
or duration or intensity. Which a lot of these kids would view as a very significant improvement. So some common relaxation
strategies that are taught and that I do with my patients are diaphragmatic breathing, progressive muscle relaxation,
and some guided imagery, personalized to what works for them. You should know of course
there are many apps, podcasts, things like YouTube clips and yoga can all be helpful as well. Many of you have heard about biofeedback and it’s really exciting
but I really try to remember that it is an adjunct to relaxation. It’s not a tool that’s
gonna heal the child in and of itself. But what it does is it really provides either auditory or visual kind of feedback about what they’re doing to
their body when they relax. And it can be very empowering. It can help them understand
what they’re doing and motivate them to stick with it. So there’s a number a variety
of modalities that we use from pretty low tech to high tech. But all it does is it really shows the kid this is what you’re doing to your body and we teach them a little bit about this is a mechanism,
this is what’s happening. And if you practice regularly, this is something that can
be really be helpful for you. But again, it’s that regular practice. So in our well-rounded,
comprehensive treatment of headaches, you may
at some point consider referring to a psychologist to help with persistent chronic or
episodic headaches or migraines. Some of the things you might
want to bring a psychologist on board to help with are things like, when they’re not adhering
to medication regimens. When they’re avoiding a lot of school they say because of the
headaches and migraines. If you already know or
have identified presence of depression, anxiety,
or other health conditions that may impact their headaches or how they treat their headaches. Or if the family just
expressed an interest in non-pharmacological pain management, this is a great place
to have a psychologist come out and help. So you may consider whether
to refer to specialists in pain psychology, such as us at Mott, or whether a general child
or adolescent psychologist in your practice or in the
community may be of help. So we really work best when
we’re working with kids when the primary concerns are
really around the headache. So things like, I’m
worried about my headaches, or my headaches are making me
not perform as well in school. And when there’s kinda mild depression or anxiety symptoms present. I can usually detect that by saying like, what are you stressed out about? As opposed to like, do
you have anxiety disorder? But if depression or anxiety
is much more generalized, pervasive, disruptive to life, that’s when I would really consider primarily addressing those, and hopefully that will help address the headaches, and maybe pain psychology
can be an adjunct to that but primarily kinda considering
the depression or anxiety. So thank you very much. (audience applauding) – About two more minutes, is it good? All right, I don’t. So when you’re evaluating a headache what you wanna look at is blood pressure, the head circumference
particularly a small kid. Whether they have sinus tenderness. You wanna do a good, careful
neurologic examination, including looking in their eyes. Look for depression, look at sleep. And then two overlapping slides, when do you image and when do you refer? And I don’t know the right
answers for all these. So we wanna do an imaging
study, preferably an MRI, when there’s an abnormal
neurologic examination, when there’s signs of increased
intracranial pressure, that is the headaches are
improving with sitting up or frequently wake the kids at night. Although I have to tell
you, most of the headaches that wake people at night are migraines. When there’s a
progressively severe course, or even a change in the severity or the quality of the headache, so kids with migraines
can develop brain tumors and we can’t forget that. When do you refer to a neurologist? Overlapping again, abnormal
neurologic examination, there’s associated seizures,
changes in mental status, things you’re doing just aren’t working. And we’re available for advice as well. Other signs of increased
ICP, onset after trauma or they’re abusing analgesics. The role of the primary caretaker, I think you have to be
able to diagnose migraines and know when the headache is more worrisome than being a migraine. Know when to image and when to refer or do one or the other. Be familiar with abortive medications and I would say at
least two preventatives, and feel free to use them,
that’s really your job. Let’s lead into a program
we’re just starting. We’re totally overwhelmed
with referrals for headaches. And it’s making me sick
but our wait time now is about 14 months to get into our clinic and we’re not taking people who have not been on preventative, not failed a preventative. But we wanna do better for
the kids and for you guys so what we’re starting is something called Pediatric Headache ECHO. So this is a program
that we’re just starting. It’s to train primary caretakers in terms of how to take care of kids. So this is a telementoring program where we’re gonna have a
series of eight sessions. Each one if gonna be
about 15 or 20 minutes of didactic talks, but then
the rest of it’s going to be case presentations that the participants, and there’ll be about 20
participants, you know, per round of eight sessions,
we’ll present their cases and discuss ’em with the
experts and with each other, the idea being that you
really become experts at treating the headaches and
can manage them on your own. It’ll allow us to see the
kids we really need to see in the clinic faster,
and allow your patients to get managed faster and better without having to wait. So you’ll be getting publicity on this, it’s getting started at the end of May. And we’re actually really
excited about starting. There’s a family that donated money to support a coordinator for it and it’ll be a fun thing, thank you. (audience applauding)

  1. 14:31 Cyproheptadine "fast acting so consider when urgent" – wouldn't this mean it should be rather used in an acute migraine than as prophylaxis?
    Also, the drugs presented (Amitriptyline, Topiramate) are more for peds than for adults?
