Headache for the PCP: Evaluation and Initial Management Chris Jackman, MD Assistant Professor of Neurology Child Neurology of Riley Hospital Director, Riley Headache Center Objectives • • • • Identify a systemic evaluation of a headache patient Evaluate for causes of secondary headache Recognize how to diagnose common primary headache symptoms of childhood Identify how to treat primary headache syndromes Initial Evaluation 1. Shoulder shrug and look to parents 2. “I don’t know” 3. “Headaches?” It’s in the history • Time course • Time course • Time course • Pain description – Location – Severity – Quality • Associated symptoms Other questions: • Pain description – Location – Severity – Quality • Associated symptoms – – – – – Aura Nausea, vomiting Photophobia, phonophobia Light-headedness, vertigo Autonomic features Red Flags • Time course – Progressive – Morning • Location – Posterior • Postural • Focal neurologic signs – Any • Systemic signs – Fevers, rash • Family history – As in, none • Age – Under 6 years Physical exam • • • • • • Eyes / Fundus TMJ Face Muscles Skin Neurologic Secondary Headaches Non-neurologic causes of secondary headaches • • • • • • • Dental/ TMJ Allergies/ congestion Sinus inflammation/ infection Ear infection/ Mastoiditis Hypothyroidism Pheochromocytoma (Hypertension) Eye-strain It is (probably) not a tumor • Brain tumors are very rare • BUT… – You only need to miss one to be incompetent • The chance of finding a tumor in a patient with headaches and a normal neurological exam is… It is not a tumor • Very low, but not quite zero • Brain tumors typically cause headache when they cause increased pressure • A much more common presentation is focal neurologic signs with minor headache It is a tumor • Key features – Time course (Progressive) – Timing (On awakening) – Postural (Supine) – Focal Neurologic signs – Seizures If it’s not a tumor, what is it? Intracerbral Hemorrhage • Features – Time course (Acute) – History of trauma – Focal Neurologic signs • Types of hemorrhage – – – – – Subdural Epidural Subarachnoid Paranchymal Interventricular Venous sinus thrombosis • Associated with primary or secondary hypercoagulable state • Present with signs of increased intracranial pressure • Sometimes hemorrhage • Red Flags – Time course (Progressive or static) – Postural – Neurologic signs • Papilledema • 6th nerve palsies Ideopathic intracranial hypertension • • • • Mechanism unknown More female, more obese Headache with visual loss Red Flags – Time course (Progressive or static) – Postural – Neurologic signs • Papilledema • 6th nerve palsies Ideopathic intracranial hypotension • Seen in some connective tissue diseases from dural ectasia (or ideopathic) • Mimics LP headache • Red Flags – Time course (Progressive or static) – Postural Meningitis / Encephallitis • Red flags: – Systemic signs (fever) – Focal Neurologic signs (meningismus, encephalopathy, seizures) Chiari I Malformation • • Protrusion of cerebellar tonsils below the foramen of Monro Red flags: – – Location (posterior) Postural, pain with neck movements – Focal Neurologic signs (ataxia) – Worse with cough, sneezing, valsalva Post-traumatic or Post-concussive Headache • Red flags: See hemorrhage • Will get better, may take months • Cognitive changes are common, will also improve Headache Evaluation Do I order LABS? Headaches in children younger than seven years of age Chu ML, Shinnar S. Arch Neurol, 49:1992; 79-82 • Study of 104 children referred to Child Neurology • Studies performed prior by the pediatrician • Studies included: – – – – Cell counts Basic electrolytes Tranaminases Urinalysis • “Uniformly unrevealing” • Similar prospective study in adults of 193 patients showed same results Do I order a SCAN? American Academy of Neurology Practice Parameter: Evaluation of children and adolescents with recurrent headaches 2002 • Neuroimaging – Combined 6 studies – 605 of 1275 had imaging (CT in 116, MRI in 483, both in 75) – 97 children with imaging abnormalities (16%) • 79 considered incidental • 14 surgically treatable • 4 medically treatable American Academy of Neurology Practice Parameter: Evaluation of children and adolescents with recurrent headaches 2002 • Of the 14 surgical lesions: – 10 tumors – 3 symptomatic vascular malfomations – 1 significant arachnoid cyst • All had an abnormal neurologic examination – – – – Papilledema Abnormal eye movements Motor dysfunction Gait dysfunction American Academy of Neurology Practice Parameter: Evaluation of children and adolescents with recurrent headaches 2002 – Parameters which distinguish headache patients with space occupying lesions • • • • • Headache of less than one month duration Absence of a family history of migraine Abnormal neurological examination Gait abnormalities Seizures – Those patients with headaches for less than 6 months and at least one of the above symptoms are considered “high-risk” • “High-risk” = 4% chance of space occupying lesion CT vs. MRI? Primary Headache Disorders Migraine Diagnosis and Treatment: Results From the American Migraine Study II Headache 2001;41:638-645 • Survey mailed to 20,000 homes, identified 3577 individuals who met criteria for migraine • 48% had previously received a physician diagnosis • 24% of those undiagnosed had missed at least one day of work or school in the previous three months • Those missed were: – Lower income – Younger age (18-29) – Male Migraine epidemiology • Headache prevalence – Tension type HA 78% – Migraine 16% – Children • 3-8% by age 3 • 37-52% by age 7 • 57-82% in 7-15 year olds • Peak incidence – Women – age 12-13 (aura), 14-17 (without) – Men – age 5 (aura), 10-11 (without) Comprehensive Review of Headache Medicine; Levin M Ed; Oxford 2008 “If nothing is wrong with me, doctor, why do I have these headaches?” Migraine pathophysiology • Primarily a NEUROGENIC process • We think • For now Migraine pathophysiology • Aura – Cortical spreading depression – Front of profound depolarization – Moves across cortex ~ 3mm/min – Following by suppression of neural activity lasting minutes A.P. Leão. Cortical Spreading Depression Migraine pathophysiology Migraine without aura Pediatric diagnostic criteria • • • • • At least five attacks fulfilling criteria B-D (below) Headache attacks lasting 1 to 72 h Headache having at least two of the following characteristics: – Unilateral location, may be bilateral, frontotemporal (not occipital) – Pulsing quality – Moderate or severe pain intensity – Aggravation by or causing avoidance of routine physical activity (eg, walking, climbing stairs) During the headache, at least one of the following: – Nausea or vomiting – Photophobia and phonophobia, which may be inferred from behavior Not attributed to another disorder Migraine with aura Pediatric diagnostic criteria • • At least two attacks fulfilling the criteria B-D (below) Aura consisting of at least one of the following, but no motor weakness: – – – • At least two of the following: – – – • Fully reversible visual symptoms, including positive features or negative features (e.g., flickering lights, spots, or lines) Fully reversible sensory symptoms, including positive features (i.e., pins and needles) or negative features (ie, numbness) Fully reversible dysphasic speech disturbances Homonymous visual symptoms or unilateral sensory symptoms At least one aura symptom develops gradually over 5 min or different aura symptoms occur in succession over 5 min Each symptom lasts between 5 min and 60 min Not attributable to another disorder And… …Chronic Daily Headache… Chronic Daily Headache • Transformed (or chronic) migraine – History of migraine – Progresses to chronic, low level headache with periodic migraines • Chronic tension type headache – Lack significant migranous features – Less severe intensity – Tightening more than pulsating • New daily persistent headache Chronic daily headaches evaluation • Look for red flags* • Ask about analgesic overuse * Especially in New Daily Persistent Headache Practice Parameter: Pharmacological treatment of migraine headache in children and adolescents D.

Silberstein, MD NEUROLOGY 2004; 63: 2215–2224 Migraine treatment - Abortive • Ibuprofen, acetaminophen, ketorolac, indomethacin, ASA • Combinations (Acetaminophen/ASA/caffeine) • Antiemetics (promethazine, chlorpromethazine • Opiates, barbituates (no, no, never…) • Corticosteroids • Triptans – 5HT1b, 1d, and 1f agonists – Contraindications include cardiovascular disease or risk factors, Reynaud’s, hemiplegic migraine – Side effects include nausea, dizziness, chest and throat tightness Migraine treatment - Abortive Migraine treatment Prophylactic • When to use prophylaxis – Headaches frequent – Headaches severe – Headaches disruptive • Side effects and burden of taking a daily medicine < the life disruption caused by (appropriately treated) headaches Migraine treatment Prophylactic • • • • • Antihistamines Beta-blockers Tricyclics Anticonvulsants Calcium channel blockers Migraine treatment Prophylactic • Antihistamines – Cyproheptadine • • • • Little studied, often used Reduce headaches from 8.4 to 3.7 per month Somnolence, weight gain Initial dose 1-2 mg QHS, max 4 mg BID Lewis D, Diamond S, Scott D, et al. Prophylactic treatment of pediatric migraine. Headache 2004;44:230–237. Migraine treatment Prophylactic • Beta-blockers – Propranolol most studied – Three small, prospective class II studies with conflicting results – Exercise intolerance – Contraindicated in asthma, depression – Initial dose 20 mg, up to 160 mg Migraine treatment Prophylactic • Tricyclics – Amitriptyline most studied – Anticholinergic effects, somnolence – Black box warning re: suicidality – Baseline EKG and monitor for QT prolongation – Initial dose 10 mg up to 100 mg – Give at dinner Migraine treatment Prophylactic • Anticonvulsants – Topiramate (or zonisamide) • Best studied – Valproate • Effective but side effects can be significant – Levetiracetam/ Lamotrigine • Limited (poor) data Migraine treatment Prophylactic • Calcium channel blockers – Conflicting data – Familial hemiplegic migraine – Abdominal discomfort – Monitor EKG and blood pressure Chronic Daily Headache Treatment • Preventative medications – – Evidence is spotty at best • Topiramate is best studied, anecdotally all migraine medications may work – Transformed migraine or for medication overuse – early prophylactic treatment – Chronic tension type headache – late medical treatment – New daily persistent headache – doesn’t matter Non-pharmacologic Treatment • Lifestyle! Lifestyle! Lifestyle! – Analgesic overuse – Sleep – Diet – Psychiatric Non-pharmacologic Treatment • Analgesic overuse – Opiotes/ barbiturates > triptans >>NSAIDS – Any used over 15 days/month, some over 10 days/month – Can treat by a period of elimination or by moderation – Headaches may take 4-6 weeks to improve Non-pharmacologic Treatment • Sleep – Snoring – Movements – Quality – Quantity – Continuity Non-pharmacologic Treatment • Diet – Meats (Iron, B12) – Vegetables (Folate?) – Skipping meals – Hydration – Caffeine Non-pharmacologic Treatment • Psychiatric evaluation – Anxiety – Depression – Obsessive-compulsive disorder • Non-pharmocologic management – Biofeedback – Self-hypnosis – Relaxation Take home points: • Red flags – Progressive time course – Postural – Worse in the morning – Any neurologic sign or symptom – Worse with valsalva • Practice your fundoscopic and cranial nerve exam Closing thoughts… • • • • • Watch for red flags Know when to image If unsure whether to image, refer Know helpful lifestyle modifications Know when to start or refer for prophylactic medications • Remember: “Your patient does not want to have a headache” References • • • • • • • • • Sargent JD, Solbach P.
