1. Define concepts of a migraine headache
and migraine variants from other headache
types in the pediatric/adolescent population
2. Discuss pathophysiology of migraine
headaches
3. Discuss indications for diagnostic testing
for migraines
4. Identify appropriate treatment strategies
for acute migraine management
5. List types of preventive versus abortive
treatments for headaches and migraines
6. Discuss when referrals to pediatric
neurology are needed for further evaluation
and management
Moderate to severe pain:
◦ Unilateral/bilateral
◦ Throbbing/squeezing
2 of 3 cardinal features:
◦ Photophobia
◦ Inability to function
◦ Nausea/vomiting
Exertional worsening
Sound sensitivity
Duration of 4 to 72 hours
Similar to migraines without aura
20 – 30 % migraneurs have aura (99% of these
have visual auras)
Warning symptoms may include:
◦
◦
◦
◦
Visual disturbances
Numbness in arm or leg
Difficulty speaking
Warning symptoms last 5 – 6 minutes and typically
are followed by headache pain
Headaches occurring on or > 15 days per
month
Current or prior diagnosis of migraine
Lasting on average > 4 hours per day
Obesity
Lowered social economic status
Stressful events
Snoring
Overuse of caffeine
Depression
Anxiety
Use of over-the-counter medications more
than 1 – 2 times per week
Overuse of abortive prescription medications
Abdominal migraines
◦ Diffuse abdominal pain, sometimes associated with
headache
◦ Can last 1 – 72 hours
Benign paroxysmal vertigo
◦ Usually occurs in toddlers and young children
◦ Appear off balance, may refuse to walk
◦ Can last minutes to hours
Cyclic vomiting
◦ Occurs in school-age children
◦ Forceful, frequent vomiting lasting 1 hour to 5 days
4 -5% of young children
5 – 6% in preadolescents
Increases in adolescence
18% women, 6% men as adults
Migraine Prevalence (%)
AGE- AND GENDER-SPECIFIC
PREVALENCE OF MIGRAINE
Lipton RB, Stewart WF. Neurology. 1993.
Strong family history of migraines
Foods:
◦ MSG, peanuts, chocolate, caffeine, cheese,
nitrites
Chronobiology: sleep disturbance
Environmental: weather changes
Stress: school, family changes,
moving
Physical: sports activities, heat
Letdown: weekends, vacation, end
of projects
Sinus infection
◦ Nasal congestion
◦ Nasal drainage
◦ Pain over frontal or maxillary sinuses
Dull, aching, nonthrobbing
Not associated with vomiting
Pain or discomfort in the head, scalp, or neck,
usually associated with muscle tightness in
these areas
Brain lesion
Subarachnoid hemorrhage
Meningoencephalitis
Acute hydrocephalus
Chiari I malformation
Pseudotumor Cerebri
Imaging studies
◦ CT vs MRI
If new onset severe headache
Hard to treat or progressive headaches
AM headaches/AM vomiting
Focal features on examination
Poor family history
Blood tests
◦ R/O causes for fatigue, possible infection, thyroid
abnormalities
Lumbar puncture
◦ If concerns with papilledema
Lifestyle modifications
◦ Diet
Increase water
Decrease caffeine
Decrease nitrates
◦ Sleep
◦ Dealing with stress
Decrease use of over-the-counter
medications
Phamacologic therapy
Functional response (ability to return to
normal activities)
Consistent and quick onset
Prevent headache recurrence
Well tolerated
Cranial vasoconstriction
Peripheral neuronal inhibition
Modulates activity in neuroreceptors at
multiple sites along trigeminal pathway
Nonspecific: (for
mild/moderate pain)
◦
◦
◦
◦
◦
NSAIDs
Combination analgesics
Opioids
Neuroleptics/antiemetics
corticosteroids
Specific (for severe pain)
◦ Triptans
◦ Ergotamine (DHE)
Oral therapies: most
medications
Nasal sprays: sumatriptan,
zolmitriptan, DHE
Injectable: (SQ, IM, IV)
sumatriptan, DHE,
injectable NSAIDs, opioids,
neuroleptics
Suppositories: antiemetics,
ergots, opioids
Imitrex (sumatriptan) and Maxalt (rizatriptan)
– usually tier 1 on insurance formularies
Use at early onset migraine
May repeat 1X in 2 hours if needed
Maximum 2 doses in 24 hours
Should be used no more than 2 times per
week
Decrease attack frequency (by 50%) duration
and intensity
Improve responsiveness to acute treatment
Improve function and decrease disability
Migraine significantly interferes with patient’s
daily routine, despite acute Rx
Acute medications contraindicated,
ineffective, intolerable AEs or overused
Frequent headache (>1 - 2 attacks per week)
Uncommon migraine conditions
Patient preference
Anticonvulsants
◦
◦
◦
◦
◦
Valproate
Gabapentin
Topiramate
Zonegran
Neurontin
Antidepressants
ß-adrenergic
blockers
◦ TCAs
◦ SSRIs

antagonists

First line preventive treatment
◦ Corticosteroids – for daily headaches that have
been occurring for several weeks
◦ Topamax (topiramate) - consider weight/eating
habits
◦ Amitriptyline – consider mood, sleep difficulties
◦ Cyproheptadine – consider for young children
◦ Calcium channel blockers/beta blockers – consider
if mildly hypertensive

Refer children and adolescents with
headaches if:
◦
◦
◦
◦

◦
Poor response to acute treatment
Uncertainty of diagnosis
Unusual features
Co-morbidities
Need for preventive treatment
Concerns or alarming findings on examination
