Pattern Reversal and Flash Visual Evoked Potentials in Patients with Migraine and Tension-Type Headache

Objective: Migraine and tension-type headache (TTH) are the most common primary headaches. It was aimed to obtain information about pathophysiology of these headaches by performing visual evoked potentials (VEPs) patients with migraine TTH. Material Methods: Healthy individuals, episodic migraine, TTH were included in this prospective study. Pattern reversal flash VEPs performed all participants. VEP applied while interictal period. In addition, severity analyzed Visual Analogue Scale (VAS). Results: Thirty-one healthy 27 patients, 31 Age gender not different between groups (p>0.05). VAS scores (8.0±1.2) higher than those (6.5±1.1) (p <0.001). The mean right/left P100 wave latencies control, TTH, 89.8±7.5/91.0 ± 6.2, 91.0±4.9/91.3±5.2, 97.6±8.1/97.1±7.5 ms, respectively. P2 104.7±15.9/104.8±14.5, 98.6±11.5/98.7±10.8, 115.5±16.3/118.3±6.2 P100, P2, N3, P3 waves group control (p<0.05). Conclusion: This study showed that had controls patients. These findings may indicate central mechanisms as well peripheral play a role originates from tissues.
