Blink Reflex Response in Migraine - A Clinical Study

Blink reflex is a polysynaptic reflex. It is a non-invasive method that can provide information on peripheral and central neurological functions of trigemino-vascular mechanisms for migraine. Numbers of studies are done by the researchers of western countries on habituation responses of blink reflex and its importance in the treatment of migraine. In our study indicate the small changes in latency, amplitude and interval of blink reflex among migraine patients, but the values are not statistically significant. This may be due to a difference in the patients approach after the migraine attack to the neurology department. Most of the migraineurs are out patients, so further study on the important of blink reflex could not be done. Habituation of the trigemino-vascular system by electrical stimulation of the supra-orbital nerve is an important for bio-feedback mechanisms in controlling migraine.
