Objective: Investigate the utility of caloric testing and videonystagmography in the dizzy patient as it may relate to vestibular migraine. Study design: Retrospective cohort. Setting: Tertiary referral center in an ambulatory setting. Patients: 28 adult patients with a complaint of dizziness presented to a combined dizzy clinic and completed a migraine questionnaire in addition to caloric testing. Intervention: Migraine questionnaire administered in addition to caloric testing already indicated for dizzy patients. Main outcome measures: Responses to migraine questionnaire and nystagmus sum frequency (eye speeds) from caloric testing. Results: After exclusion criteria, 28 patients were included in the analysis. 13 Dizzy patients who answered 'yes' to two or more questions on the migraine questionnaire (migraine group) were compared with 15 patients that answered 'yes' to less than two questions (non-migraine group). Affirmative response to 2/3 of the first three questions was previously demonstrated to have good sensitivity and specificity for migraine headache 1 . The nystagmus sum beat frequency including right and left ears with warm and cold water caloric testing was measured. Patients in the migraine group vs. patients in the non-migraine group had a mean nystagmus frequency of 97 and 99 beats respectively. A trend was observed in which migraine patients were four times less likely to have a sum nystagmus frequency less than 50 than those in the non-migraine population 7.7% (1/13) vs. 26.6% (4/15) respectively (p=0.33). Conclusions: Nystagmus sum frequency observed between the migraine and non-migraine group was remarkably similar. The migraine group was observed to have a trend sum frequency less than 50 four times less than the non-migraine group. Further investigation is necessary to determine the utility and reproducibility of these findings.
