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
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
Thunderclap headache
New onset headache
Headache with neurologic signs
Headaches in pregnancy
Headaches in elderly
Progressing headaches
Changes in frequenc or quality of headache
Prepared to manage migraines 48%
Prepared to manage MI, DKA, Asthma 95%
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.
New onset headache
Headache with neurologic sign
Headache with seizure
Headache with elevated ICP

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
Relatively solid recommendations
– Not indicated in patients with migraines and normal exam
– Indicated in patients with headache and abnormal exam
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
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
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
Acute
Preventive
– Life style
– Pharmacologic
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

– 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.
Not more effective
Not specific for underlying pathophysiology
Sedating
Positive reinforcement?
Potential for abuse
Public health crisis
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
Establish and maintain routines
– Sleep

Meals
Exercise
Dietary triggers
– Caffeine, chocolate, alcohol, aged cheeses, monosodium glutamate

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
“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.”

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
Identify and eliminate triggers
Amitriptyline
Symptomatic treatment with NSAID
Avoid overuse
Stress management
¾ of patients with chronic daily headaches overuse analgesics
Transformed migraines
– Past history of discrete migraines
Butalbital/aspirin/acetomenophen/caffeine
Codeine, propoxyphene, oxycodone, hydrocodone
Aspirin, acetomenophen
NSAID
Nasal decongestants and antihistamines
Ergotamine

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
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
