Kathie Teta, RN, CPNP PANDA Neurology Atlanta, Georgia 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 ◦ MAOIs ◦ Propranolol Calcium channel antagonists – Verapamil Others – – – – – NSAIDs Riboflavin Magnesium Petadolex Feverfew Condition Asthma Depression Athlete Avoid b-Blocker Epilepsy Arrhythmia Bipolar Tricyclic Antidepressant TCA Peptic Ulcer Disease NSAIDs Peripheral Vascular Disease Ergots/Triptans Adapted from Silberstein S. Headache in Clinical Practice. 2002:93. 56 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 Behavioral Treatments Relaxation training* Hypnotherapy Thermal biofeedback training* Physical Treatments Acupuncture Electromyographic biofeedback therapy* Transcutaneous electrical nerve stimulation (TENS) Cognitive/behavioral management therapy* Occlusal adjustment *Proven effective in clinical trials Cervical manipulation Adapted from US Headache Consortium Headache Guidelines. www.aan.neurology.org. 2000 Botox injections Nerve blocks Trigger point injections Nerve stimulator trials Transcutaneous sumatriptan (battery powered) Livodex – inhaled DHE 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
