Migraine headaches are "a class of disabling primary headache disorders, characterized by recurrent unilateral pulsatile headaches. The two major subtypes are common migraine (without aura) and classic migraine (with aura or neurological symptoms)."[1] Laymen often use the term for any severe headache, especially with nausea and sensitivity to light and sound, but there are specific criteria. Just as the term is overused in some contexts, however, true migraine has different manifestations, is underdiagnosed, and is sometimes preventable as well as treatable.

Classification

  • Common migraine (without aura)
  • Classic migraine (with aura or neurological symptoms)

Diagnosis

Migraines are underdiagnosed[2] and misdiagnosed.[3] About a third of headaches that patients report as being migraines are truly migraines[4]; while about 90% of headaches that are self-reported not to be migraines are truly not migraines.[4] The diagnosis of migraine without aura, according to the International Headache Society, can be made according to the following criteria, the "5, 4, 3, 2, 1 criteria":

  • 5 or more attacks
  • 4 hours to 3 days in duration
  • 2 or more of - unilateral location, pulsating quality, moderate to severe pain, aggravation by or avoidance of routine physical activity
  • 1 or more accompanying symptoms - nausea and/or vomiting, photophobia, phonophobia

For migraine with aura, only two attacks are required to justify the diagnosis.

The mnemonic POUNDing (Pulsating, duration of 4-72 hOurs, Unilateral, Nausea, Disabling) can help diagnose migraine. If 4 of the 5 criteria are met, then the positive likelihood ratio for diagnosing migraine is 24.[5]

The presence of either disability, nausea, or sensitivity to light can diagnose migraine with[6]:

Treatment

Abortive treatment

General-purpose analgesics, from acetylsalicylic acid and acetaminophen, to NSAIDs to opioids, may be useful in attacks, but there are some potential problems with overuse. Caffeine may improve their effectiveness. When the diagnosis is confirmed, much more specific drugs may be useful.

Since the pain comes significantly from dilated blood vessels, drugs that contract the painful vessels, with due care for vascular disease that may increase risk, are disease-modifying. In the past, ergotamine was the standard, but it has significant risks although it is still used. The triptan class of specific vasoconstrictors is now the standard. There are some agents that desensitize the receptor involved the vasodilation.

High dose acetylsalicylic acid (1000 mg), sumatriptan 50 mg and low dose ibuprofen 400 mg are equally effective at reducing pain to mild or none at two hours according to a randomized controlled trial; however, sumatriptan was led to more patients being pain free at two hours (37% versus less than 33% for other groups).[7]

Phenothiazines, such as prochlorperazine 10 mg parenterally and chlorpromazine 0.04 to 0.1 mg/kg parenterally, are more effective than placebo and more effective than metoclopramide according to a meta-analysis of randomized controlled trials.[8]

Combination therapy

A combination of sumatriptan 85 mg and naproxen sodium 200 mg was better than either drug alone according to a randomized controlled trial funded by the manufacturer of the study drug.[9]

Nonpharmacological treatments

Investigational treatments

Corticosteroids may help prevent recurrence after abortive treatment according to a meta-analyses of randomized controlled trials with number needed to treat of nine[10] or 10[11].

Telcagepant (MK-0974), an oral antagonist of calcitonin gene-related peptide receptor, may be as effective as zolmitriptan but with less drug toxicity according to a randomized controlled trial.[12]

Preventive treatment

Perhaps a third of patients meet consensus criteria for preventive treatment.[13]

The antiepileptic drug topiramate can increase response among patients with migraine according to a randomized controlled trial.[14]> The relative benefit increase was 113.0%. For patients at similar risk to those in this study (23.0% had response), this leads to an absolute benefit increase of 26%. 3.8 patients must be treated for one to benefit (number needed to treat = 3.8). Click here to adjust these results for patients at higher or lower risk of response.

Prognosis

Migraines with auras in mid-life may be associated with stroke[15] and brain infarcts on magnetic resonance imaging[16].
