Why does migraine cause vertigo?

Vertigo is a common presentation of Migraine. Balance depends on the brain comparing information from the inner ears, vision and the body. During a migraine attack, altered sensory processing can make those signals feel mismatched, creating a sensation that you or the room is moving when it is not.

Vertigo is different from feeling faint or generally unsteady. It may come with nausea, motion sensitivity, light sensitivity or headache, but it can also happen without head pain. Because inner-ear conditions and other illnesses can also cause vertigo, a new or changing pattern deserves a clinical assessment.

Sit or lie down promptly when vertigo starts, and rise slowly once it settles. Keep a clear path to the bathroom, use support on stairs, and avoid driving, cycling, swimming alone or using machinery while you feel the room spin. A quiet, low-light space and your usual migraine plan may help.

Record the sensation, whether head movement triggered it, how long it lasted, associated migraine symptoms and any medicines taken. This helps a clinician decide whether the episodes fit migraine-related vertigo or need another evaluation.

Call emergency services for vertigo with new face drooping, weakness, numbness, trouble speaking, severe difficulty walking, fainting, chest pain, a sudden severe headache, double vision or new hearing loss. These symptoms need urgent assessment and should not be managed as a routine migraine attack.

Make a medical appointment for a first episode of vertigo, recurring episodes that are changing, persistent imbalance, ear pain or hearing symptoms, or attacks that interfere with work and daily activities.

Ask how to describe your dizziness accurately, whether your symptoms suggest migraine-related vertigo, and which symptoms would need emergency care. Bring a note of timing, head movement, hearing changes, nausea and medication response.
