The content of my presentation will include discussion of unapproved or investigational uses of medication for acute and preventative treatment of migraine headache

in children

ObjectivesObjectives

• Understand diagnosis of primary headache in children using the International Classification of Headache Disorders (ICHD-3)

• Develop an appropriate treatment plan for children diagnosed with migraine headaches

• Recognize when to refer children with migraine headaches

Migraines are CommonMigraines are Common

• There are 28 million people in the world with Migraine

• Migraines occur at all ages

Migraine headaches in children and adolescents are often under recognized or

NOTNOT taken seriously

Pediatric Migraine ImpactPediatric Migraine Impact

• Migraine - Top 5 most prevalent childhood disorders

• Headache - 3rd ranked illness - related cause of school absence

• Pediatric migraine - $36 billion impact in USA

• WHO Survey - rates severe migraine with quadriplegia as one of the Most Disabling chronic disorders

What is the Key to Diagnosing What is the Key to Diagnosing Migraine?Migraine?

• Accurate Diagnosis

• Effective Communication

International Headache SocietyInternational Headache Society (IHS) (IHS)

• Classification system for headache diagnosis developed in 1988

• International Classification of Headache Disorders 3rd Edition (ICHD-3)

Headache ClassificationHeadache Classification

1. Primary: Headache is the Problem

2. Secondary: Symptom of Underlying Disorder

3. Painful cranial neuropathies, other facial pains and other headaches

Diagnosing MigraineDiagnosing Migraine

Migraine without AuraMigraine without AuraICHD-3, 2013ICHD-3, 2013

• At least 5 attacks

• Last 4 -72 hours untreated (2 - 72 for children under 18 years of age)

• Two of four characteristics– Unilateral location (commonly bilateral in kids)– Pulsating quality– Moderate or severe intensity– Aggravated by routine activity

Migraine without AuraMigraine without AuraICHD-3, 2013ICHD-3, 2013

• During the HA at least one of the following:

– Nausea and/or vomiting

– Photophobia and phonophobia (may be inferred by child’s behavior)

• Not attributed to another disorder

Migraine with AuraMigraine with AuraICHD-3, 2013ICHD-3, 2013

• Criteria same as Migraine without Aura but also have:

– Focal neurological symptom usually developing over 5-20 minutes and lasts less than 60 min

– Visual, Sensory, Speech, Motor, Brainstem, Retinal

– At least 2 attacks

– Headache begins during the aura or follows aura within 60 minutes

Chronic MigraineChronic MigraineICHD-3, 2013ICHD-3, 2013

• Headache occurring on 15 or more days per month for > 3 months, which has the features of migraine headache on at least 8 days per month

• Often results from unresolved status migrainosus


Status MigrainosusStatus MigrainosusICHD-3, 2013ICHD-3, 2013

• Present attack meets criteria for migraine without aura and is typical of other attacks

• Both of the following– HA > 72 hours – Severe intensity


• Interruption during sleep and short lasting relief due to medication are disregarded

Challenges of Treating Pediatric Challenges of Treating Pediatric MigraineMigraine

• Diagnosis and assessment of symptoms is complicated by the inability of children to articulate their complaints

• Other infectious, allergic, or gastrointestinal disorders of childhood may mimic symptoms of migraine

• Lack of research conducted in children and adolescents

ICHD-3, 2013ICHD-3, 2013

• Frontal HA with pain in one or more regions of face, ears or teeth

• Clinical, nasal exam, CT and/or MRI imaging and/or lab evidence of acute or acute-on-chronic rhinosinusitis

• Simultaneous onset of headache and facial pain

• Headache and/or facial pain resolve within 7 days after successful treatment

• At least 10 attacks (more than once but less than 15 days/mos)

• HA lasting from 30 minutes to 7 days

• At least 2 of the following:– Pressing/tightening quality– Mild or moderate intensity– Bilateral location– Not aggravated by routine physical activity

Episodic Tension-TypeEpisodic Tension-TypeICHD-3, 2013 ICHD-3, 2013

• Both of the following:

– No nausea or vomiting (anorexia may occur)

– Photophobia or phonophobia


Medication-Overuse HeadacheMedication-Overuse HeadacheICHD-3, 2013ICHD-3, 2013

• Analgesics at least 15 days/mos for > 3 mos

• Triptans at least 10 days/mos for > 3 mos

• HA has developed or markedly worsened during analgesic overuse

• Headache resolves or reverts to previous pattern within 2 months after stopping analgesics

• Daily low dose medication use worse than high dose use once a week

• Caffeine can also be culprit

Medication-Overuse HeadacheMedication-Overuse HeadacheVasconcellos, et al, 1997Vasconcellos, et al, 1997

Retrospective review of pts > 4 HA/wk• N = 98, mean age = 12.1

Frequency of HA per month– Initial = 27.5– After 1 mo. without analgesics = 7.3– After 2 mo. without analgesics = 5.4(P<0.0001)

Daily use of analgesics may reduce the effectiveness of preventative HA meds

Acute headache attributed to traumatic Acute headache attributed to traumatic injury to the headinjury to the head

ICHD-3, 2013 ICHD-3, 2013

• Traumatic injury to the head has occurred

• Headache is reported to have developed within 7 days after one of the following:– 1. the injury to the head– 2. regaining of consciousness following the injury to the head– 3. discontinuation of medication(s) that impair ability to sense or

report headache following the injury to the head

• Either of the Following:– Headache has resolved within 3 months after the injury to the head– Headache has not yet resolved but 3 months have not yet passed

since the injury to the head

So How Do You Treat Pediatric So How Do You Treat Pediatric Headaches?Headaches?

• Acute

• Preventative

• Biobehavioral

• Treat attacks rapidly and consistently without recurrence

• Restore patient’s ability to function

• Minimize the use of rescue medications

• Optimize self-care and reduce use of resources

• Cost-effectiveness

• Minimal or no adverse events

Goals of Acute TreatmentGoals of Acute Treatment

Acute Migraine TreatmentAcute Migraine Treatment

• Over-the-Counter Medication– Ibuprofen most effective in children

Dosage: 10 mg/kg (Hamalainen, et al, 1997)– Naproxen sodium (Aleve) may be substituted for

ibuprofen – Aspirin and Excedrin are other options (> 16 years)

• 24-32 ounces of sports drink for vascular rehydration at HA onset

Early Treatment = Successful Treatment


Faster Onset of Action:– Almotriptan (Axert)– Eletriptan (Relpax)– Rizatriptan (Maxalt, Maxalt-MLT)– Sumatriptan (Imitrex-tablet, NS, SQ,)– Sumatriptan + Naproxen sodium (Treximet)– Zolmitriptan (Zomig, Zomig-ZMT, nasal spray)

Slower Onset of Action:– Frovatriptan (Frova)– Naratriptan (Amerge)


No Narcotics!

• Use of opioids prevents reversal of established migraine and central sensitization (Jakubowski et al. Headache 2005; 45:850-61)

– Patients with migraine were given parenteral sumatriptan and ketorolac

– 71% were pain free and without allodynia within 60 minute of ketorolac infusion

– In contrast to the responders (9/9), non-responders (1/19) had treated their migraine with opioids

Medication Overuse PreventionMedication Overuse Prevention

• Limit analgesic use to 2-3 days a week

• Triptan use limited to 6 headaches a month

• Limit: No more than 2 doses of medication per headache- need IV acute tx if HA persists

Management of Intractable Acute Management of Intractable Acute MigrainesMigraines

When do you Refer for Intravenous Acute When do you Refer for Intravenous Acute Headache Treatment?Headache Treatment?

• Acute / Non-responsive to home abortive treatment

• Chronic Migraine - Impaired functioning

• Chronic Migraine - Acute exacerbation

Acute Headache Treatment AlgorithmAcute Headache Treatment Algorithm

Migraine Preventative TreatmentMigraine Preventative Treatment

Goals of Migraine PreventionGoals of Migraine Prevention

• Reduce HA attack Frequency, Severity and Duration

• Improve Responsiveness to TX of Acute Attacks

• Improve Function and Reduce Disability

• Improve Quality of Life

• Educate Patient/Family to become Active Participants in HA Management

Common Preventative MedicationsCommon Preventative Medications

Antidepressants– Amitriptyline (Elavil)

Anticonvulsants– Topiramate (Topamax)– Valproic Acid (Depakote)– Levetiracetam (Keppra)

Antiserotonergic– Cyproheptadine (Periactin)

Neutraceuticals

-Vitamin B2 (Riboflavin)

-Coenzyme Q10

-Vitamin D3

Botulinum toxin A (Botox)

Botox (onabotulinumtoxin A)Botox (onabotulinumtoxin A)

• Injected directly into overactive muscles

• Reduces contractions, relaxes muscles

Preventative Treatment PrinciplesPreventative Treatment Principles

• Criteria to Start: – Frequency >1 week and/or – Disability from HA

• Purpose is to prevent not cure migraines

• Never expect a lifetime of preventative treatment

• Start low and go slow when increasing dose to limit side effects

• Full response to medication not seen until on full dose for at least 6-8 weeks

• Slowly wean medication after treatment goal (3-4 HA/month) for 4-6 months

• No medications FDA approved for migraine prevention in children

Biobehavioral TreatmentBiobehavioral Treatment(“Healthy Habits”)(“Healthy Habits”)

Common Headache TriggersCommon Headache Triggers (Riback, P., 2000) (Riback, P., 2000)

• Eliminate Caffeine• Diuretic • Addictive• Caffeine-Withdrawal Headache

Healthy Eating HabitsHealthy Eating Habits

• Regular meals and snacks

• Encourage regular intake of fruits, vegetables, and dairy

• Food triggers uncommon in children

Healthy Sleep HabitsHealthy Sleep Habits

• Recommend 8-9 hours– No Naps

• Keep regular sleep schedule– Do not oversleep more than 2-3

hours on weekend, especially on Sunday

– Avoid naps

• Establish a bedtime routine to help child fall asleep

ExerciseExercise

• Three times a week for 20-30 minutes

• Hydrate before, during, and after exercise– May need 32 ounces before and after exercise to

prevent dehydration triggered headache– Sports drink is best

• Do not exercise before bedtime

School Issues: Proactive ApproachSchool Issues: Proactive Approach

– Provide School Letter with Acute Headache Treatment Plan, Hydration/Restroom Needs

– Recommend Parent/Child Review Headache Tx Plan with Teachers

– Discuss Expectations for School Attendance with Headache

– Evaluate Headache Disability at Each Visit

When to Refer for Specialty Care?When to Refer for Specialty Care?

Child PsychologistChild Psychologist

• Lifestyle changes

• Stress management

• Learn coping strategies for chronic pain

• Teach Biofeedback-Assisted Relaxation Techniques

Child Neurologist/Headache SpecialistChild Neurologist/Headache Specialist

• Any concern about a secondary cause of headaches (unless it is sinus disease)

• Headaches that do not meet ICHD-II criteria

• Headaches unresponsive to treatment interventions

• Transient neurological signs during headache episodes

ConclusionsConclusions

• Migraine headaches are common and may often be under-recognized - Think Migraine!

• Diagnosis should rely on standardized criteria

• Imaging should be guided by “warning signs” with specific criteria used as suggestions

• Multi-modal treatment may be necessary:Acute Preventative Healthy Habits Pain Management

• Consider referral for Headache Specialty Care
