[Vestibular migraine]

Among varieties of migraine characteristic of liquidators of effects of the Chernobyl catastrophy and ChNPP personnel migraine with a manifest vestibular component holds a prominent place. As many as 803 middle-aged patients, average age (39.6 +/- 11.8) years, were examined. Among these were the ChNPP personnel, liquidators, and migrators from Pripyat, who had received low doses of radiation to 0.5 rem. Used in the examination were questionnaire survey (HOACK), vestibular tests (Uemura, Fukuda, etc.), nistagmography, cardiography with Takagasi loading tests, multisensory evoked potentials. Virtually all examinees demonstrated disturbances in the vestibular function. Of these, 92.4 percent of subjects had headache complaints. In 35 percent of the examinees, pain was of a typical migranous character. Additional signs included asthenization, vegetative symptomatology, vestibulocardial syndrome, emotional derangements. The histamine blocking agents dimenhydrinate and betaserk proved to be the most effective treatment options in the above patient population.
