Migraine, a neurological disorder that causes severe disability, is characterized by recurrent moderate to severe attacks associated with vegetative symptoms. Patients with frequent attacks may overuse drugs, which can lead to migraine chronization and headache. In the last decade, neuromodulatory approaches have been developed for the treatment of headaches that do not respond adequately to treatment. Non-invasive neuromodulation techniques are an evolving field in migraine research and treatment. Non-invasive vagus nerve stimulation is one of the non-invasive neuromodulation techniques. Promising findings on vagus nerve stimulation in people with chronic pain, including migraine and cluster headaches, are slowly being recognized. Stimulation of the vagus nerve provides a way of regulating autonomic tone. Auricular vagus nerve stimulation regulates abnormal sympatho-vagal balance while activating the parasympathetic system, including anti-inflammatory pathways (cholinergic anti-inflammatory pathway and hypothalamic-pituitary adrenal axis). It is aimed to evaluate the effect on pain and pulse variability after vagus nerve stimulation in women with migraine disease and to learn how the vagus nerve crosses according to the pulse measurements taken from the right and left index fingers.
