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]
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]:
- sensitivity of 81%
- specificity of 75%
Treatment
Abortive treatment
Corticosteroids may help prevent recurrence after abortive treatment according to a meta-analysis of randomized controlled trials.[7]
Comparative studies
A randomized controlled trial found that 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; however, sumatriptan was led to more patients being pain free at two hours (37% versus less than 33% for other groups).[8]
Another randomized controlled trial, funded by the manufacturer of the study drug, found that a combination of sumatriptan 85 mg and naproxen sodium 200 mg was better than either drug alone.[9]
Preventive treatment
Perhaps a third of patients meet consensus criteria for preventive treatment.[10]
The antiepileptic drug topiramate can increase response among patients with migraine according to a randomized controlled trial.[11]> 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.
