“An additional study showed some fascinating associations between Meniere syndrome and vestibular migraine. Thirteen percent to 18% of those initially diagnosed with probable or definite vestibular migraine developed bilateral, low-frequency sensorineural hearing loss within 9 years. Interestingly, 7% to 11% developed cochlear symptoms that met the American Academy of Otolaryngology, Head and Neck Surgery (AAO-HNS) criteria for bilateral Meniere syndrome  .”
" Finally, one study showed that caloric testing triggers a migraine in some individuals. In this study, 39 individuals with a history of a migraine underwent caloric testing. Within 24 hours, 19 of these individuals developed their typical migraine symptoms. 47% of those that developed a migraine within 24 hours actually developed a migraine during testing. This study design used a matched control group and only one of 21 from this group developed a migraine within the initial 24-hour period after testing . This finding is perplexing, leading one to believe that peripheral vertigo can be a trigger of a migraine or migraine-related symptoms."
