This feeling is different from feelings of fainting or uneasiness as experienced during motion sickness. A vertigo episode lasts for few minutes to 72 hours. You experience moderate to severe symptoms that hinder your everyday activities.
At least half of the episodes happen with one of the following migraine symptoms:
- A headache that has any of the two of these characteristics: one-sided, pulsating, moderate to severe, gets worse with activity
- Sensitivity to light or sound
- Seeing flashing lights before your eyes (a migraine aura) at the beginning of a vertigo spell
Neurologists and Neuro-otologists are specialized in diagnosing and treating vestibular migraine. Patients with a vestibular migraine require lifestyle modifications like eating and sleepingon time reducing caffeine, salt and alcohol intake. For patients having more than three episodes in a month, migraine prophylasis must be started with medicines like beta blockers, calcium channel blockers, SSRI’s and antiepileptic medications. Terminating the headaches and controlling vertigo with vestibular suppressants may be necessary.
