[Trigeminal evoked potentials in migraine].
Trigeminal evoked potentials (TEP) were studied in 19 patients with migraine without aura. Significant shortening of latent periods of early and late TEP components was observed during stimulation on the side of headache as compared with the same indices during stimulation on nonalgesic side. Hyperreactivity of trigeminal vascular system in patients with migraine without aura during the period between the attacks is discussed. Asymmetry of laten TEP periods may determine the preferential side of headache, on the one hand, and may reflect the changes in trigeminal system following the repeated lateralized fits of migraine, on the other hand. Administration of 1 g of aspirin resulted in increase (normalization) of the latentions of TEP components. After efferalgan administration TEP changes were not registered. The suggestion is made that inhibitory influence of aspirin on the truncal trigeminal system is one of the central mechanisms of its action.
