1 Headache Management Fariborz Khorvash Associate Professor of Neurology

2 Why talk about headaches?

3 Headaches are a common problem They are sometimes difficult to treat Can usually be treated well by internists Headache management is often not optimal Recent advances can translate into better treatment

4 Problems in management Chest pain approach – Does this patient have a brain tumor? Episodic care Underdiagnosis of migraine headache Ineffective treatments are commonly used – Acetaminophen, Butalbital/ASA/Caffeine Inappropriate use of analgesics

5 Red Flag Signs: Thunderclap headache New onset headache Headache with neurologic signs Headaches in pregnancy Headaches in elderly Progressing headaches Changes in frequenc or quality of headache

6 Internal medicine residents Prepared to manage migraines 48% Prepared to manage MI, DKA, Asthma 95%

7 Sinus Headache? What is a sinus headache? Many patients with migraines have sinus symptoms. – Rhinorrhea, congestion, ocular symptoms occur in up to 46% of patients with migraines

8 Study of 2991 patients with sinus headaches – Self or physician diagnosed – 88% met IHI criteria for migraine Patients reported – Sinus pressure – 84% – Sinus pain – 82% – Nasal congestion – 64% Diagnosis of sinus headache should be reserved for those patients who meet diagnostic criteria for sinusitis. Schreiber, Archives of Int. Med. 2004; 164: 1769

9 Brain Imaging: New onset headache Headache with neurologic sign Headache with seizure Headache with elevated ICP Patient request …….

10 Headaches 1. Intracranial pathology 2. Contiguous structures 3. Migraine 4. Cluster 5. Tension type 6. Chronic daily/Rebound

11 Intracranial pathology Tumor Subarachnoid hemorrhage Meningitis Pseudotumor cerebri

12 Tumor 111 consecutive patients with primary or metastatic brain tumor – Classic early morning headache is uncommon – Primary symptom in only - 44% – Worse with bending over - 33% – Similar to TTH in 77%; migraine in 9% – Nausea and vomiting – 40% Forsyth, Neurology, 1993

13 Imaging Relatively solid recommendations – Not indicated in patients with migraines and normal exam – Indicated in patients with headache and abnormal exam

14 Less solid recommendations Headache worsened by valsalva, exertion, sex Abrupt onset or awakens patient from sleep Change in established pattern New headache in patient >50 Progressively worsening headache Comorbidities: HIV, cancer, immune suppression

15 Contiguous structures Sinuses? Eyes Ears TMJ Teeth Temporal artery Cervical spine

16 IHS criteria for migraine without aura Duration 4-72 hours Two of the following characteristics – Unilateral – Moderate – severe intensity – Pulsating – Aggravated by routine physical activity Headache accompanied by one the following – Nausea or vomiting – Photophobia or phonophobia 5 attacks No other explanation

17 Pathophysiology of migraine Old theory: vasoconstriction triggers vasodilation Current concepts – Originates as a neurologic event in the brain stem – Trigeminal nerve ganglion is stimulated – Vasodilation occurs – Serotonin release contributes

18

19 Treatment of migraines Acute Preventive – Life style – Pharmacologic

20 Principles of management Establish a diagnosis Treat early Use adequate doses Tailor treatment to the severity of attack Use migraine specific therapies Use preventive strategies Form a therapeutic alliance with the patient Empower the patient Avoid narcotics

21 Acute treatment Mild - oral – ASA 975 mg – Naproxen mg – Ibuprofen mg – Cataflam – Ergotamine 2 mg + caffeine 200 mg – Brufen/caffeine/codeine Mild with nausea – Add metaclopramide 10 mg

22 Severe – Tryptans: oral, nasal, wafer, subQ – DHE 1mg subQ, IV, nasal spray – Alternatives Ketorolac 60 mg IM – Adjuncts Promethazine Chlorpromazine (phenergan) – Narcotics

23

24 Tryptans Contraindications – CAD – CAD likely Side effects – Chest and neck pressure – Dizziness – Warmth, numbness, tingling, tightness, flushing – Nausea and vomiting

25 Though sumatriptan may not be the most effective of the tryptans, it is available generically and should be the first choice.

26 Narcotics Not more effective Not specific for underlying pathophysiology Sedating Positive reinforcement? Potential for abuse Public health crisis

27 Preventive therapies Amitriptyline mg Propranolol mg Divalproex sodium mg Sodium valproate mg Venlafaxine mg Fluoxetine mg?????? Dysport

28 All are 70% effective Reduce frequency and severity of attacks Response cannot be predicted Dose adjustments necessary Calcium channel blockers less effective Decision process

29 Life style changes Establish and maintain routines – Sleep – Meals – Exercise Dietary triggers – Caffeine, chocolate, alcohol, aged cheeses, monosodium glutamate

30 Nonpharmacologic management Effective – Relaxation training – Cognitive behavioral therapy Ineffective – Acupuncture – Hypnosis – Manipulation – TENS – Hyperbaric oxygen

31 Aspirin for migraine prevention? Observations from the Physicians’ Health Study – 22,071 doctors randomized to 325 mg of ASA or control Treatment group: 6% experienced migraine after randomization Control group: 7.4% experienced migraine Treatment effect: 20% Buring, JAMA, 1990

32 Cluster headaches “A healthy robust man of middle age was suffering from troublesome pain which came on every day at the same hour at the same spot above the orbit of the left eye: after a short time the left eye began to redden, and to overflow with tears; then he felt as if his eye was slowly forced out of its orbit with so much pain, that he nearly went mad. After a few hours all these evils ceased, and nothing in the eye appeared at all changed.” Textbook 1745

33 Clinical features Unilateral – 100% Restlessness – 93% Retroorbital – 92%, (temporal – 70%) Lacrimation – 91% Conjuctival injections – 77% Nasal congestion/rhinorrhea – 75% Ptosis/eyelid swelling – 74% Phonophobia/phophobia – 50%

34 Periodicity Duration: 8 weeks Bouts per year: 1 Maximum attacks per day: 4 Attack duration: min Nocturnal: 73%

35 Treatment Acute – Subcut tryptans 74% effective within 15 min Nasal may be effective Zolmitriptan 10 mg po – 60% response within 30 min – Oxygen

36 Treatment Prophylactic – a small trial involving 30 patients – Verapamil 120 tid 80% of patients responded – 40% at the end of one week Attacks per day after one week – Verapamil -.6 – Placebo – 1.6 Leone, Neurology, 2000

37 Other effective therapy – Prednisone Bridge to verapamil Tapered over 3 week – Lithium – Sodium valproate – Methysergide

38 Tension-type headaches Duration 30 min – 7 days Two of the following characteristics – Pressing or tightening ( not pulsatile) – Mild to moderate intensity (nonprohibitive) – Bilateral – No aggravations from walking stairs Both of the following – No nausea or vomiting – Photophobia and phonophobia absent (or only one present) 10 previous attacks

39 Management of TT headaches Acute headaches – Minor analgesics Chronic tension type headaches – Same diagnostic criteria – Occur 15 days per month

40 CTTH: An RCT Amitriptyline vs stress management vs combination – 409 patients recruited from primary care practices and randomized to one of 4 treatment groups Amitriptyline – 48 Stress management – 38 Amitriptyline and stress management – 45 Placebo – 38 Holroyd, JAMA, 2001

41 Results: All three treatment groups effective – Mean headache index score – Days of at least moderate pain – Analgesic medication use – Headache disability Amitriptyline produced results more quickly. Combination treatment (AM+SM) produced greater than 50% reduction in HA severity in 2/3 of patients

42 Treatment goals for CTTH Identify and eliminate triggers Amitriptyline Symptomatic treatment with NSAID Avoid overuse Stress management

43 Analgesic abuse or rebound headaches ¾ of patients with chronic daily headaches overuse analgesics Transformed migraines – Past history of discrete migraines

44 Analgesics implicated Butalbital/aspirin/acetomenophen/caffeine Codeine, propoxyphene, oxycodone, hydrocodone Aspirin, acetomenophen NSAID Nasal decongestants and antihistamines Ergotamine Tryptans

45 Management strategies Make a diagnosis Establish and maintain a relationship Inform the patients Stop symptomatic treatment Start prophylaxis – amitriptyline Steroid taper (ranitidine 300 bid) Recognize and treat the underlying headache disorder Guard against overuse

46 Effectiveness of treatment Most patients will stop symptomatic treatment Steroids seem to reduce withdrawal symptoms 60-70% of patients improve Improvement occurs over 6 months 30% of patients relapse

47 Conclusion How do we diagnose migraine headaches? How should we treat migraines? What causes migraines? Who needs a CT scan? How do we recognize cluster headaches? How do we diagnose tension type headaches? Does anything work for chronic daily headaches?
