“Migraine patients tend to have an increase risk of BPPV. No one has looked at vestibular migraines to distinguish that from just migraines but migraine patients in general have a slightly higher risk of BPPV. And one possibility there is, if you go back to animal studies, trigeminal noxious, trigeminal stimulation, can actually induce inflammatory changes in the inner ear. That may be a possibility. I think there was a question on the pathophysiology of migraine. So migraine is a disorder of the trigeminal cervical system where each of the trigeminal nerves and the upper cervical nerves all combine to control sensation, control pain. And so if you keep getting migraine attacks, this recurrent trigeminal activation, that could proceed theoretically cause some inflammation in your inner ear. Over time, that may be the cause of the increased risks of BPPV.”
