Association Between Benign Positional Vertigo and Migraine in Indian Population

Benign positional vertigo (BPV) occurs when freely floating otoconia which are normally attached to the utricular macula, enter the posterior semicircular canal and move under the influence of gravity. It is the most common cause of peripheral vertigo. Migraine is a common headache disorder which is characterized by hemicranial, throbbing pain and may be preceded by aura. The relation between vertigo and migraine is intriguing and in day to day practice, often not clear. 100 diagnosed patients of BPV, aged more than 20 years, were evaluated for presence of headache specifically migraine based on International Headache Classification 3rd Edition, beta version. We also compared the success of epley’s manoeuvre in patients having BPV & headache as compared to patients with complaints of vertigo alone. Overall seventy-four patients had successful epley’s manoeuver and the rest did not show improvement even after four trials. Thirty-four patients reported headache and migraine was diagnosed in only ten patients. 67.6% of patients with headache had successful epley’s maneuver however fifty-one of the 66 patients without headache had successful epley’s manoeuver. Prevalence of migraine was only 10% in patients with BPV in our population and we observed that presence of headache does not suggest success or failure of epley’s manoeuvre.
