More study is needed to better understand what causes migraine with brainstem aura. Small studies have found that most people with migraine with brainstem aura have a family history of some sort of migraine.4
As with all types of migraine, a person’s lifestyle and environment can trigger a migraine attack.
Diagnosing migraine with brainstem aura
Migraine with brainstem aura is diagnosed using the person’s description of their symptoms. This is why keeping a migraine diary can be so helpful in finding treatments and understanding your own triggers. Sometimes other tests may be ordered to rule out other health conditions. These tests include:
- Brain MRI
- MR angiogram or MRA (This test looks at the blood vessels going to the brain)
- Electroencephalogram or EEG (This test looks for evidence of seizures)
- 24-hour heart monitor
- Specialized blood tests
Treatments for migraine with brainstem aura
The most common treatments for migraine with brainstem aura include:1
- Pain killers, such as acetaminophen or ibuprofen, and anti-nausea drugs for acute treatments (after the migraine has started)
- Preventive treatments such as topiramate, verapamil, and lamotrigine
Drugs that are commonly prescribed for other types of migraines are not recommended for people who have migraine with brainstem aura. These drugs include triptans, ergotamines, and beta-blockers.
