The Blink Reflex in Migraine

Abstract: The blink reflex is an objective and useful method to study the trigeminal system. It was recorded in 43 migraine patients and the findings compared with those of 31 healthy controls. The latencies of the R1 component were in the normal range in both groups. The R2 latencies ranged between 30 and 32 ms in the control group. In contrast, more than half of the patients with migraine had R2 latencies between 32 and 35 ms in the migraine group. Some migraine patients had latencies above 35 ms. The R2 latency was s… Show more

“…However, they did not indicate whether or not this study was performed during patient migraine attack or not. They stated that these findings could be presented as objective evidence of the involvement of trigeminal afferents and/or polysynaptic pathways in the brainstem of patients with migraine headache [29]. In the present study, right- and left-sided R1, as well as R2i and R2c latency values were compared with those of the control group, and significantly longer latencies were detected in the patient group, supporting role of trigeminovascular system in migraine.…”

“…These data indicate suppression of the brainstem interneurone part of the blink reflex during a migraine headache attack. (Avramidis et al 1998) The R2 latency differs statistically significantly between control subjects and migraine patients (Bánk et al 1992). The R1 and R2 latencies, amplitudes and areas of the basal blink reflex are similar in migraineurs ictally and between migraine attacks and also in control subjects.…”
