Headache Management

Neurology

 Why talk about headaches?

 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

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

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

Internal medicine residents

 Prepared to manage migraines 48%

 Prepared to manage MI, DKA, Asthma 95%

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

 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.

Brain Imaging:

 New onset headache

 Headache with neurologic sign

 Headache with seizure

 Headache with elevated ICP

 Meningitis

 Pseudotumor cerebri

Tumor

111 consecutive patients with primary or metastatic brain tumor

Classic early morning headache is uncommon

Primary symptom in only - 44%

Similar to TTH in 77%; migraine in 9%

Nausea and vomiting – 40%

Forsyth, Neurology, 1993

Imaging

 Relatively solid recommendations

– Not indicated in patients with migraines and normal exam

– Indicated in patients with headache and abnormal exam

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

Contiguous structures

 Sinuses?

 Eyes

 Ears

 TMJ

 Teeth

 Temporal artery

 Cervical spine

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

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

Treatment of migraines

 Acute

 Preventive

– Life style

– Pharmacologic

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

Acute treatment

 Mild - oral

ASA 975 mg

Naproxen 500-1250 mg

Ibuprofen 800-2400 mg

Cataflam

Ergotamine 2 mg + caffeine 200 mg

Brufen/caffeine/codeine

 Mild with nausea

– Add metaclopramide 10 mg

 Severe

– Tryptans: oral, nasal, wafer, subQ

DHE 1mg subQ, IV, nasal spray

Alternatives

 Ketorolac 60 mg IM

Adjuncts

 Promethazine

 Chlorpromazine (phenergan)

Narcotics

Tryptans

 Contraindications

– CAD

– CAD likely

 Side effects

Chest and neck pressure

Dizziness

Warmth, numbness, tingling, tightness, flushing

Nausea and vomiting

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

Narcotics

 Not more effective

 Not specific for underlying pathophysiology

 Sedating

 Positive reinforcement?

 Potential for abuse

 Public health crisis

Preventive therapies

 Amitriptyline 25-150 mg

 Propranolol 80-240 mg

 Divalproex sodium 500-1500 mg

 Sodium valproate 800-1500 mg

 Venlafaxine 75-150 mg

 Fluoxetine 20-40 mg??????

 Dysport

 All are 70% effective

 Reduce frequency and severity of attacks

 Response cannot be predicted

 Dose adjustments necessary

 Calcium channel blockers less effective

 Decision process

Life style changes

 Establish and maintain routines

– Sleep

Meals

Exercise

 Dietary triggers

– Caffeine, chocolate, alcohol, aged cheeses, monosodium glutamate

Nonpharmacologic management

Effective

Relaxation training

Cognitive behavioral therapy

Ineffective

Acupuncture

Hypnosis

Manipulation

TENS

Hyperbaric oxygen

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

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

Mild to moderate intensity (nonprohibitive)

Bilateral

– No aggravations from walking stairs

Both of the following

Photophobia and phonophobia absent (or only one present)

10 previous attacks

Management of TT headaches

 Acute headaches

– Minor analgesics

 Chronic tension type headaches

– Same diagnostic criteria

– Occur 15 days per month

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

 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

Treatment goals for CTTH

 Identify and eliminate triggers

 Amitriptyline

 Symptomatic treatment with NSAID

 Avoid overuse

 Stress management

Analgesic abuse or rebound headaches

¾ of patients with chronic daily headaches overuse analgesics

 Transformed migraines

– Past history of discrete migraines

Analgesics implicated

 Butalbital/aspirin/acetomenophen/caffeine

 Codeine, propoxyphene, oxycodone, hydrocodone

 Aspirin, acetomenophen

 NSAID

 Nasal decongestants and antihistamines

 Ergotamine

 Tryptans

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

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

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?
