The differences in trigeminal system functional state in chronic and frequent migraine patients

Electrophysiological tools like trigeminal somato-sensory evoked potentials (TSSEP) are used for evaluation of trigeminal system (TS) functional state. The activity of the later is an important factor in migraine pathogenesis. The study aim was to analyze the TS functional state in chronic and frequent migraine patients in relation with age during the migraine attack (critic period) and in the interictal period on lateralized stimulation (left/right).
