Migraine with brainstem aura symptoms include vertigo, double vision, and slurred speech. Learn how this rare subtype is diagnosed and when to seek urgent care.
Migraine with brainstem aura symptoms can be among the most frightening in all of migraine medicine. Episodes produce neurological signs that originate in the brainstem, the region controlling vital functions like consciousness, eye movement, balance, and basic motor coordination. When those functions are temporarily disrupted during a migraine attack, the result is an experience that can look, from the outside, like a stroke or a serious neurological emergency. Understanding what this condition is and when its symptoms require urgent care are the two most important things anyone with a suspected or established diagnosis should know.
This subtype was known as basilar migraine or basilar-type migraine for decades, referencing the basilar artery at the base of the brain. The name was updated to migraine with brainstem aura to better reflect the mechanism: the symptoms arise from brainstem dysfunction during the aura phase, not necessarily from spasm or compromise of the basilar artery itself. If you have seen the older term in medical records or online, it refers to the same condition.
To meet diagnostic criteria, at least two of the following must occur during an episode, and no motor weakness should be present (which would point to hemiplegic migraine instead):
These brainstem symptoms occur in the aura phase and are fully reversible. They last from 5 to 60 minutes (each individual symptom) and develop gradually over at least 5 minutes. They are followed by, or occur simultaneously with, visual or sensory aura features in most cases, and then by headache in the majority of attacks.
The headache that follows typically has standard migraine features: pulsating, moderate to severe, worse with activity, accompanied by nausea, photophobia, and phonophobia.
The combination of vertigo, double vision, ataxia, and dysarthria is a textbook description of a posterior circulation stroke or TIA. Before migraine with brainstem aura can be diagnosed, a clinician must:
This is not a diagnosis that can be made on the basis of one episode without imaging and clinical workup.
The following require emergency evaluation, regardless of whether you have an established migraine with brainstem aura diagnosis:
If you or someone with you is experiencing these symptoms for the first time, do not drive. Call emergency services.
Migraine with brainstem aura sometimes coexists with typical migraine with aura. A person may have some attacks with pure visual aura and others with brainstem features. The presence of brainstem symptoms in even a subset of attacks is what drives the subtype classification.
People with vestibular migraine sometimes have overlapping features, particularly vertigo. The distinction matters because brainstem aura requires specific diagnostic exclusions that vestibular migraine does not. See vestibular migraine symptoms for a comparison of how dizziness presents across these two subtypes.
For context on how aura types are classified more broadly, types of migraine aura covers visual, sensory, and speech aura in detail.
Diagnosis is clinical and requires documented episodes meeting criteria, negative vascular workup, and specialist oversight. A headache neurologist with experience in rare migraine subtypes is the appropriate clinician for this condition.
Management considerations for migraine with brainstem aura differ from standard migraine in some respects, particularly around the use of certain acute treatments. Those decisions belong entirely to a clinician who knows your full medical history.
Given the dramatic nature of brainstem aura symptoms, detailed logs of each episode serve a specific purpose: they help your neurologist confirm that episodes are stereotyped (occurring in the same pattern), which is the key feature distinguishing migraine from vascular causes. An episode that looks different from the established pattern warrants prompt reassessment.
Log each episode with: date and time, which brainstem symptoms occurred, the sequence and timing of onset, whether visual or sensory aura also appeared, headache characteristics, and full recovery time. The what to log in a migraine diary guide provides a framework for this. Tracking consistently in the Migraine Tracker: CGRP Log app gives your neurologist organized data across months, not just a recalled summary of recent attacks.
For understanding how episodic and chronic patterns develop over time, episodic vs chronic migraine is a useful read alongside this one.
Only a clinician can diagnose migraine with brainstem aura and determine appropriate care. Given the overlap with posterior circulation stroke, establishing that diagnosis with full evaluation before managing episodes independently is non-negotiable.

Basilar migraine was the older name for this condition. It was renamed migraine with brainstem aura to reflect updated understanding of the underlying mechanisms and to move away from implying the basilar artery is directly responsible. The terms refer to the same clinical entity.
