Pathological forms of brain electrical activity and localization of its sources in patients with trigeminal neuralgia

No significant differences from the typical electroencephalogram were observed in patients with trigeminal neuropathy. In patients with typical trigeminal neuralgia, the electroencephalogram variations were detected both in the changes of dominant activity and in the appearance of individual pathological phenomena. The three-dimensional localization of pathological activity generators points to the involvement of the median nonspecific brainstem structures into pathological process evoked by trigeminal neuralgia.
